Recent Advances in Chemical Engineering- RACE 2012

Department of Chemical Technology, North Maharshtra University, Jalgaon Page 2



PREFACE I welcome all the participants in Recent Advances in Chemical Engineering (RACE) -2012 a one day Seminar. It

gives immense pleasure to me to bring in the notice to all that Department of Chemical Technology has been organizing two

to three conferences every year in the emerging areas of research to update the teaching and research community with the latest developments. There are four conferences/

seminars and three workshops scheduled for this academic year in the areas of Nano Technology, Chemical Engineering, Polymer

Technology, Green Chemistry, Food and Oil Technology. This (RACE-12) is the second seminar in the series of Recent Advances in Chemical Engineering (RACE) organised by the Department.

Unlike other branches of studies chemical engineering has very vast scope starting from heat transfer to mass transfer to process development to transport phenomenon to chemical thermodynamics to chemical reaction

engineering (can be based on biochemical engineering, polymer reaction engineering, reaction engineering of the inorganic materials etc.) to

mathematical modelling and simulation to plant design . Since chemical engineering deals with the chemical products development, therefore protection of environment is a very big issue. Hence seminar can’t fulfil its

purpose without discussing the environmental aspects. The relevance of the event is reflected by the more than 400 entries of participants from every corner of the country. During rheotic sessions of

deliberations of experts as well as interactions at a common platform, the budding scientists and technocrats shall certainly get the guidance and

directions with the innovative ideas. It is my belief that RACE-2012 will be a grand success event which will fulfil the aspirations of the researchers. I hope all of you will enjoy the

stay at North Maharashtra University, Jalgaon. Thanking you

Dated 4.2.2012 Prof. Satyendra Mishra Chairman, RACE-2012

Abstract

The surface roughness as output cutting parameter is needed to be address for

production of goods with precision and quality. An experimental investigation and modeling

of cold work tool Steel AISI H13 (hardness 51 HRC) is presented. An experimental

investigation and prediction model for the surface roughness of hardened die steel is

presented in this paper. Adaptive Neuro-fuzzy inference system (ANFIS) is used in

prediction model using speed, feed and depth of cut as an input cutting parameter and surface

roughness as an output parameter. The measured surface roughness (Ra) is compared with the

predicted using bell shape, triangular and trapezoidal membership function. It is observed that

the average prediction accuracy using triangular membership function is 99.88 %.






STPW (SPENT TEA POWDER WASTE) AS AN ADSORBENT FOR

REMOVAL OF NICKEL FROM WASTE WATER S. L. Pandharipande, Sachin M. Pokale

Associate Professor, M Tech (Chem Engg),Nagpur

Chem. Engg. Dept., LIT, RTM NU, Nagpur

Abstract

Adsorption is a separation operation for the removal of a constituent of a gas, vapor or

liquid by a surface or interface. There are two types of adsorption phenomena, physical and

chemical. Physical adsorption: A readily reversible phenomenon, as the result of

intermolecular forces of attraction between molecules of the solid and the substance

adsorbed. The solid is highly porous, containing many fine capillaries, the adsorbed the

adsorbed substance will penetrate these interstices if it wets the solid. The industrial

adsorption operation depends upon this reversibility for recovery of the adsorbent for reuse,

for recovery of the adsorbed substance, or for the fractionation of mixtures. Removal of

metallic compounds from waste water is a challenging task for chemical engineers.

The present work has suggested a novel adsorbent in the form of treated spent tea powder for

removal of Ni from waste water and is carried in following parts:

Procurement and treatment of used or spent tea powder waste (STPW).

Determination experimentally, the equilibrium relationship using spent tea powder

waste (STPW) and activated charcoal as adsorbents for varying concentrations of Ni

in water solution. The analysis of Ni is done at Govt of India recognized laboratory.

The comparison of the adsorption efficiency of activated charcoal with STPW is also

carried out.

Abstract

Continuous and increased thrust for improvement in quality and product throughput

has made process industries to undergo major transformation in process operation in the

recent past. As majority of the process industries now operates at relatively higher operating

conditions of process variables there is an increased risk of accidents, or occupational

exposure to hazardous chemicals in process plants. Considering a number of such hazardous

process industries (such as petrochemical, polymeric materials, chlor-alkali, nitration, fiber,

etc.), these days the process industries are one of the most vulnerable to major disasters.

Vivid reminders of few disastrous events related to process industries are Union Carbide,

Bhopal India; Icmesa Chemical Company, Seveso, Italy.Even, after these disasters and

subsequent timely updated legislations in safety management changes thereof, there are

reports of continuous accidents and incidents reoccurring in the chemical process industries.

Some of the reported accidents of last decade are discussed in the paper. Such incidents

reiterate the concern of safety for process workers. From the reports of the accidents, it can be

inferred that the root cause of all these events depends on the variety of interrelated factors

such as social environment, fault of a person, and unsafe act and conditions. This realization

and the increased awareness to prevent or at least reduce the frequency of occurrence of such

accidents, major efforts are needed towards raising the level of safety and understanding all

the underlying factors that result in an accident, incident and the disaster. It is realized that a

number of shortcomings exist in implementing OHSMS.Therefore, an attempt is made to

explore the OHSMS practices of Indian industries, identify the loopholes and hindrances for

its implementation. Real life examples from Indian process industries have been considered

to access the level of OHSMS implementation with respect to Indian context.



CHITOSAN NANOPARTICLES AS DELIVERY SYSTEMS FOR

THIOGUANINE Sangeetha Kumar, Lekshmi Ajithkumar*, K.Sathish Kumar

Department of Chemical Engineering, SSN college of Engineering, kalavakkam – 603 110.

Abstract

Chitosan nanoparticles have gained more attention for drug delivery because of their

better stability, low toxicity, simple method of preparation and providing versatile routes of

administration. The aim of this paper was to evaluate the prospective of chitosan

nanoparticles as carriers for an anticancer drug, 6-Thioguanine. Chitosan nanoparticles (CT,

CTG, CTI, CTGI) were prepared in the presence of gold, iron oxide and gold-iron oxide

nanoparticles by Solvent evaporation method. Fourier transform-infrared analysis revealed no

possible interactions among the constituents with the chitosan nanoparticles. Scanning

electron microscopic analysis showed that the particles were nearly spherical in shape with an

average size of 100-150 nm. The diameter of gold, iron oxide, gold-iron oxide nanoparticles

were determined using TEM techniques and were found to be in order of 5-20 nm.

Encapsulation efficiency (%) of thioguanine in chitosan-gold nanoparticles showed

considerable increase over thioguanine in chitosan without gold nanoparticles. The rate of

controlled release of Thioguanine encapsulated Chitosan with gold, iron oxide and gold-iron

oxide nanoparticles was carried out in 0.1M phosphate buffer (pH 7.0) and 0.1M HCl

solution. The data resulted from experimental studies indicated that the rate of drug release

for Thioguanine encapsulated Chitosan with gold and gold-iron oxide nanoparticle was

controlled and steady when compared to Thioguanine encapsulated Chitosan with iron oxide

nanoparticles. Application of in vitro drug release date to various kinetic equations indicated

higuchi matrix model indicating uniform distribution of thioguanine in the nanocapsules.

Abstract: Bulk emulsion explosive is an important rock breaking explosive as it has excellent

detonation characteristics and good water resistance. It is safe and can be charged quickly.

The matrix of this emulsion is non-explosive in nature. The emulsion explosive compositions

contain a water immiscible organic fuel as a continuous phase, an inorganic oxidizer salt

solution as a discontinuous phase and an emulsifier. To make it explosive, air bubbles are

incorporated in the matrix by addition of different chemical gassing agents like aqueous

solution of sodium nitrite and aqueous solution of sodium bicarbonate. Low matrix

temperature does not favour the gas bubbles formation and therefore an accelerator is

required to enhance the rate of gassing. Sodium bicarbonate was used as a gassing agent and

acetic acid as accelerator. The present study attempts to determine the optimum amount of

gassing agent and accelerator to be added to emulsion matrix at low temperatures to achieve

the desired rate of gassing.

Keywords: Chemical gassing, Temperature, Viscosity, Accelerator, Gassing agent.



ANALYSIS OF VELOCITY DISTRIBUTION AND FLOW BEHAVIOUR

OF INDUSTRIAL DUCTS USING CFD

Mechanical Engg.Dept., Govt. College of Engg., Jalgaon

Abstract

This paper focuses on a design modification to a number of industrial ducts using

Computational Fluid Dynamics (CFD) analysis considering all flow features relating to the

duct system efficiency. The main objective of this paper is to provide improved flow

conditions into the top of a gas furnace wind box and along the duct with no re-circulation,

minimum pressure losses and low turbulence levels. A geometrically 3D CFD model is

assembled to capture the complex air pre-rotation before approaching the blower, air

circulation in the blower region and airflow in the duct system to a boiler. First the CFD model

is validated with experimental data at three fan Variable Inlet Vane (VIV) percentage

openings. Then, a parametric study is carried out to remove recirculation regions in the duct.

The recommended modifications provided a significant improvement in minimizing

recirculation regions in the duct and subsequent testing of modified duct system has validated

the approach using CFD analytical tools.

CFD analysis helps to optimize the design of a number of industrial ducts. The ducts

are used to provide air to a gas boiler in a power station. Usually the ducts are suffering from

a low efficiency due to air circulation inside the duct, high turbulence intensity into the top

of a gas furnace windbox and pressure differentials at burner injector inlets. In this paper we

analysed two duct systems and provided preliminary design concepts for the redesign of the

systems based on a detailed flow analysis.

Abstract:

A DRUG broadly speaking, is any substance that, when absorbed into the body of a

living organism, alters normal bodily function. In pharmacology, a drug is a CHEMICAL

SUBSTANCE used in the treatment, cure, prevention or diagnosis of disease or used to

otherwise enhance physical or mental well being. Drugs are usually distinguished from

endogenous Bio-chemicals by being introduced from outside the organism. Drugs both

MEDICINAL and RECREATIONL, can be administered in a variety of ways rather than just

one. Drug delivery system generally classified into Primary, Secondary and Tertiary

categories.

Recent studies have led to significant advances in understanding the impact of key

drug carrier properties such as, SIZE, SURFACE CHEMISTRY and SHAPE on their

performance. The successful drug delivery carries to navigate through multiple physiological

hurdles including Reticulo Endothelial System (RES) clearance, target accumulation,

intracellular uptake and endosomal escape. Each of these processes may require unique and

often conflicting design parameters, thus making it difficult to choose a design that addresses

all these known hurdles.

Researchers have attempted for many years to develop drugs based on QSAR

(Quantative Structure Activity Relationships) and simultaneously based on Kernel

Regressions (Algorithms). However, access to computational resources was not available

when these efforts began, so attempts consisted primarily of STATISTICAL

CORRELATIONS of structural descriptors with biological activities. This presentation will

discuss the application of QSAR & KERNAL in drug design. Some examples which will be

presented on computer assisted drug and molecular design and some, on computer-based

Visualization and Modeling.

Abstract

Triclopyr is a selective herbicide used to control woody plants and broadleaf weeds. The

herbicide is absorbed by leaves and roots and is moved throughout the plant in both the phloem

and xylem. Triclopyr acts as a synthetic auxin, giving a plant an auxin overdose which interferes

with growth. Since it has a low Henry‟s Law Constant, except for spray drift, triclopyr is not

expected to be found in air. In soil and water the conversion of TBEE and TEA to triclopyr acid is

rapid, thus the fate of triclopyr acid is the focus of most research. TBEE and TEA hydrolyze

quickly in natural water, while triclopyr acid has little tendency to hydrolyze at all. It is a

conservative method for the registered uses of triclopyr BEE. More realistic methods for this

product are under-development. The use of a farm pond to model exposure to species that inhibit

fast-flowing streams and the use of triclopyr BEE at rates less than the modeled maximum label

rates are also being developed. The method indicated very minimums of the direct acute risks to

the endangered and threatened fish for all registered uses of triclopyr BEE.

Abstract

Owing to the unfavorable impact on the environment of mineral oil-based lubricants,

there has been a steady increase in the demand for biodegradable, environment-friendly

lubricants. The two step process for the production of biodegradable lubricant-based stocks

from epoxidized used cooking oil and its methyl esters with a lower pour point via Amberlite

IR 120 as catalysts was developed. This involves ring-opening reactions by alcoholysis. The

ring-opening reaction of epoxidized used cooking oil was carried out with alcohol in presence

of Amberlite IR 120 as a catalyst and identity of products was confirmed by IR and 1H-NMR

spectra. The favorable physico-chemical properties like viscosity, acid value, pour point and

cloud point, oxidative and thermal stability of the resulting product was determined. The data

indicates that these epoxides have significant potential to be used as fuel additives or

lubricating fluid.

Abstract

In this work Membrane Distillation is applied to concentrate orange Juice.

Clarified orange juice (11o Brix) obtained from fresh fruits and a sugar solution was

subjected to membrane distillation. The experiments were performed on a flat sheet

module using orange juice and sucrose solution as feeds. The concentration of a sucrose

solution, used as a model fruit juice and also orange juice, was carried out in a direct

contact membrane distillation using hydrophobic PTFE membrane of pore size 0.2 μm and

porosity 70%. Surface modification of PTFE membrane has been carried out by

treating membrane with alcohol and water solution to make it hydrophilic and then

hydrophobicity was regained by drying. The influences of the feed temperature, feed

concentration, flow rate, operating time on the permeate flux were studied for treated and

non treated membrane. In this work treated and non treated membrane were compared in

terms of water flux, Within the tested range, MD with surface modified membrane

the water flux has been significantly improved by treating the membrane surface.

Abstract

Distillation is the primary separation process used in the chemical industry for liquid

mixtures separation. Apart from the numerous advantages of the distillation, it has a

drawback, namely its significant energy requirement. In order to reduce the energy

consumption of these systems energy integration is applied within the distillation columns or

with other units of the global process. The specific literature offers a large number of

solutions for the energy integration. During the process design it is important to select the

best applicable energy integration for the distillation system in the case of given separation

task. Apart from the economic criteria, nowadays the environment consciousness and

controllability are also important parameters of the process design.

The primary motivation of the study is to elaborate a complex process design

methodology that evaluates the distillation systems based on exergetic, economic and

greenhouse gas (GHG) emission aspects for the separation of azeotropic mixture of isobutyl

alcohol and isobutyl acetate using extractive and pressure swing distillation column

sequences. The aim of the methodology is to determine how the pressure swing distillation

should be applied in process design to obtain information about the accuracy of the design

alternatives. The methodology is tested and demonstrated on pressure swing distillation. The

studied distillation systems are compared to other extractive distillation and to the non-

integrated conventional arrangement in the case of the separation of ternary mixtures.

Applying the proposed methodology reveals that among the investigated distillation schemes

the pressure swing distillation proves to be the best applicable since it shows the most

favored features in a wide and flexible range. The application of the methodology on the

energy integrated distillation proofs the accuracy of the complex evaluation methodology. On

the other hand, it highlights and demonstrates that the exergy analysis can predict the results

of the economic study and the environmental evaluation to make the decisions, associated

with process design, much simpler.

Abstract

Biomass is all plant and animal matter on the Earth's surface. Harvesting of biomass

such as crops, trees or dung and using it to generate energy such as heat and electricity, is the

bio energy. Biomass is categorized on the basis of type of nature and availability of wastes

and organic residue. This waste biomass is converted into useful fuel by different process

such as pyrolysis, combustion, destructive distillation, gasification & anaerobic bio-

gasification.

Pyrolysis is thermal degradation of biomass in complete absence of oxidizing agent.

Pyrolysis of biomass gives rise to three different products: solid (charcoal), liquid (tar) and

gases (CO, CO2, H2, CH4, hydrocarbons). In the present study, pyrolysis of saw dust

particles of size 250 µm is carried out in the muffle furnace considering the temperature

range of 773 K-1073 K. The effect of temperature and residence time on volatiles and char is

analyzed. It is found that as the temperature and residence time increases the amount of

volatiles increases and the amount of char particles and unburned saw dust decreases till it

achieve steady state.

Abstract

MCM-22 was used to synthesized different metal loaded catalyst by ion exchange of

the respective ions into MCM-22 at 900C. The prepared catalyst were used to catalyzed the

benzylation of naphthalene with benzyl chloride (BC). The catalyst activity increased with

increased with increase in benzyl chloride to naphthalene mole ratio and selectivity towarde

the mono-benzylated product increases. 40% Zn-MCM-22 has been found to be an efficient

and reusable catalyst for Friedel-Crafts alkylation reaction in high yield. In the current work,

it is found that ZnCl2/ MCM-22 zeolite exhibit superior catalytic activity and shape

Abstract

This research paper evaluates the knowledge in industrial fire safety. Fire safety is

one of the most important factor in an industrial establishment to prevent the loss of lives &

property as well as damage to the environment.However, in spite of several advances made in

fire detection and fire fighting, fire continues to be highly unpredictable and hence the best

course of action is to put the maximum emphasis on fire prevention. Fire safety system aims

to achieve a defence-in-depth concept and provides direction to select the optimum

combination of the three levels - prevention, detection & suppression and mitigation to ensure

safety.

This paper on fire safety is an attempt to highlight the importance of fire safety in all

facilities. The consequences of fire are colossal. The means to enhance fire safety measures,

are enumerated below:-

a) Cognizance of Fire risk - The fire risk should never be ignored or overlooked or

underestimated in industries.

b) Prevention of Fire – Efforts should be put to prevent initiation of fire through

preventive measures.

c) Prompt detection – Early detection helps a lot in mitigating losses/damages to

personnel and property.

d) Fire Safety attitude -The causes of fire like presence of combustibles, ignition sources

and gases /vapors evolved during combustion and their hazards involved etc. should be

demonstrated.

The information provided in this paper is of general nature hence brief and adequate for

instituting a fire safety programme in industries.

Key words :- Industrial fire risk, fire prevention, fire safety attitude.

Abstract

The Monitor computer program has been specifically designed to analyse fouling

trends in heat exchanger networks. It is a vital weapon in the battle to reduce exchanger

fouling costs and maximise profitability.It is a rigorous monitoring tool that makes proper

and timely analysis of heat exchanger network economics quick and easy. It also uses

rigorous thermodynamic methods to simulate fluid behavior. Flash calculations predict the

separation of a two-phase fluid into liquid and vapour and include handling of water as a

separate phase. It is also used for the fouling calculations; Fouling Calculations are the main

simulation calculations in the Monitor computer program. On a case-by-case basis, the

program determines the heat, material and pressure balances over all the units in the network

and the fouling coefficient for each exchanger. If you later want to investigate the effect of

different fouling factors on the furnace inlet temperature, use the Specify Fouling calculation.

This calculation allows you to modify fouling factors for any or all exchangers and determine

exchanger exit temperatures. The results are shown in the specify fouling report which

shows the calculation history, exchanger exit temperatures and the furnace inlet temperatures.

The software also used for the generation of the PFD, as with any simulation program, all

Monitor operations work from a drawing of the Process Flow Diagram which displays the

units in the Network and the streams that connect them. The PFD is created graphically using

point and click, drag and drop. The important strength lies in its ability to identify trends that

are due only to changing fouling resistances and not caused by other factors, such as

changing crudes and product slates and varying ambient conditions which all conspire to

mask the real trends. The software allows us to perform routine calculations for a number of

Networks with a minimum of effort. This software provides the flexible output. You can

export the PFD drawing to PowerPoint so that you can use it in a presentation. You can get

results tables displayed directly on the screen. You can have a summary of Reconciliation,

Fouling and NFIT runs for a range of cases. You can plot results from a range of cases to

view trends.

Abstract

In order to determine initial conditions for preparation of polybutadiene with given

physicochemical characteristics, a fuzzy neural network (FNN) model was constructed to

estimate the physicochemical characteristics of the polymer (the ratio of cis form polymer

and the polydispersity index (PDI) and the conversion ratio from the initial conditions in the

batch polymerization process. The mean absolute errors of the FNN model for the conversion

ratio, the ratio of cis form polymer and PDI as the actual scale were 7.13, 0.23 and 0.17%,

respectively. Analyzing for the constructed FNN model, the relationships between the

process conditions and physicochemical characteristics were obtained as IF_/THEN rules.

Using the constructed FNN model and a genetic algorithm (GA) combined with reliability

index (RI), the process conditions with the given physicochemical characteristics and

conversion ratio were calculated. The calculated and actual process conditions showed an

average relative error of 3.9%.

Abstract

In the present work production of hydrogen using aluminum and aluminum alloys with

aqueous alkaline solutions was performed. Nowadays, new processes of H2 generation from

water via Al corrosion are mainly limited by Al passivation. This process is based on

aluminum corrosion, consuming only water and aluminum which are cheaper raw materials

than other compounds used for in situ hydrogen generation, such as chemical hydrides. In

principle this method does not consume alkali because the aluminate salts produced in the

hydrogen generation undergo a decomposition reaction that regenerates the alkali.

While in the current work, alloy of aluminum with silicon have been taken. Effect of

aluminum and aluminum alloy concentration, corrosion time and pH on generation of

hydrogen was studied. SEM was used to study the changes in surface properties of metal

occurring due to corrosion. The obtained result showed that Al/Si alloy produces more

hydrogen than aluminum, although with a low reaction efficiency reaching a hydrogen

production yield upto 14 % at pH 12. Maximum production of hydrogen from Al/Si alloy

upto 800 cm3. Furthermore, an improvement of hydrogen production rates and yields was

observed varying aluminum alloys composition and increasing their reactive surface, with

interesting results for Al/Si alloys. The development of this idea could improve yields and

reduce costs in power units based on fuel cells which use hydrides as raw material for

hydrogen production.

SOLAR POWER SATELLITE: THE SOLUTION TO WORLD’S

ENERGY CRISIS

Abstract

Space solar power is a challenging, long-term opportunity to tap space's unlimited

resources rather than relying only on Earth's limited ones. It will help sustain human life on

Earth and, at a future time, in space. Space has a number of advantages for solar power.

Resources are limited but the desires are unlimited. The solution to this problem of finite

sources is to utilize terrestrial renewable energy resources to the maximum extent possible,

while at the same time developing Space solar power a global, 24-hour-a-day energy supply.

The volume of solar energy hitting the earth is more than twice that generated by all the

forms of energy sources – both conventional and non-conventional put together. The energy

received from the Sun in just one hour is sufficient enough to meet the entire global energy

demand for around one year. Electricity generation using photo-voltaic cells is receiving

increasing attention as a means of electricity generation that produces neither CO2, NO2 nor

SO2 pollution as do systems using fossil fuel burning, nor radiation like nuclear power

systems. However, because solar energy generation is impossible at night and of poor

efficiency during cloudy weather, stable electricity generation is difficult. However, if solar

panels are launched into space they can produce power continuously, independent of the

weather and of the day-and-night cycle. The Solar Power Satellite (SPS) concept involves a

satellite carrying photo- voltaic panels in geo-stationary orbit (GEO) to generate electricity,

and transmitting this power to the Earth's surface. Solar power generation, especially space

solar power, is one of the most promising alternative technologies for reducing CO2

emissions and thus reducing “Green House Effect”. This paper gives the design principles of

the solar power satellite, the components and their functions and how it becomes a reliable

solution to energy crisis.





APPLICATIONS OF COMPUTATIONAL FLUID DYNAMICS IN

CHEMICAL ENGINEERING

Hyderabad Campus, Shameerpet -500078 (A.P)


Abstract CFD is a branch of fluid mechanics that uses numerical methods and algorithms to

solve and analyze problems that involve fluid flows. Computers are used to perform the

calculations required to simulate the interaction of liquids and gases with surfaces defined by

boundary conditions. This makes it possible to achieve various results without actually

performing the experiment.

In this paper, various applications of CFD in chemical engineering involving fluid

flow, heat and mass transfer are discussed. Starting from basic applications like nozzles,

diffusers, heat exchangers, catalytic converters, even the most recent and advanced

applications of CFD which include food processing and chemical reactor design have been

studied. CFD models and sample simulations are also included in this paper for the sake of

better understanding.

Using computational fluid dynamics to design commercial-size batch and continuous

reactors can eliminate subjective experience and empiricism, and lead to better-designed,

more-efficient units. When modeling chemical reactors using CFD, the fluid-flow patterns

and temperature fields are calculated from conservation equations for mass, momentum and

enthalpy. Using Ansys Fluent, fluid flows under various conditions have been simulated. For

reacting flows, the mixing and transport of chemical species needs to be calculated using

species-transport equations. Each equation is a statement of conservation of a single species.

Multiple- species equations can be used to represent components in a mixture, each of which

has different physical properties. To balance the mass transfer from one species to another,

reaction rates are used in each species conservation equation, and have as factors, the

molecular weights, concentrations and stoichiometries for that species in all reactions.

Abstract

In the area of green synthesis, design of catalyst free reaction is an important goal for

chemist. In this regard, the use of glycerol in portfolio of available green solvents as a

reaction solvent has attracted great attention in the recent past and has become an active area

of research in green chemistry. Literature survey reveals that tetrazole have important

properties as precursors of a verity of nitrogen containing heterocycles. They also have been

used in wide range of applications in material science, pharmaceuticals and synthesis of non-

covalent complex.

Tetrazole moiety has greater synthetic interest, prepared via [3+2] cycloadition

reaction starting from organic nitriles and sodium azide in glycerol under catalyst free

condition. The corresponding 5-substituted 1H-tetrazole were obtained with good excellent

yields (68-95%)

Abstract

The global chemical industry faces a range of challenges nowadays in increasing the

energy efficiency, reduce energy consumption in the process and environmental pollution.

Novel technologies and radical improvements are required to address these challenges.

Carbon- di -oxide, a green house gas which contributes to global warming has to be removed

from the flue gas to adhere to environmental regulations. Conventional removal of Carbon-

di-oxide from flue gas is done by amine absorption followed by stripping. However, in

membrane separation process, the separation takes place without phase transition thus saving

energy. A membrane contactor has the advantages of both membrane technology and

absorption technology. It also has many advantages over conventional contacting devices

such as high surface area per unit volume of contactor, separate control of gas and liquid flow

and known gas – liquid interfacial area. The absorption rate of CO2 per unit volume of the

membrane contactor is 2,7 times higher than that of the packed column because of the

increased gas-liquid contacting area. In a membrane contactor the membrane serves as an

interface between the feed gas and the absorption liquid. In the case of separation of CO2

from flue gas stream, CO2 diffuses from the feed gas side through the membrane pores and is

then passed to the liquid phase and absorbed in the absorption liquid.The objective of the

present work is to mathematically model a membrane contactor for the separation of Carbon-

di-oxide from flue gas. Poly vinylidene florid (PVDF) membrane contactor is mathematically

modelled for the separation of Carbon-di-oxide from a flue gas mixture using Mono Ethanol

Amine (MEA) aqueous solution by considering fully developed laminar flow in the tube side,

constant tube and shell side pressures, wetted mode model, negligible axial dispersion, real

gas behaviour, steady state and iso-thermal operating conditions.

Abstract

In this study, we used effective technology for the extraction of waste water.

Extraction was carried out with 90% (v/v) ethanol to obtain sericin powder. Micro-particulate

drug delivery of aceclofenac was prepared by gelation technique using a blend of sodium

alginate, chitosan and sericin as release retardant. The formulations were investigated for

various evaluation parameters like in vitro drug release, ex-vivo mucoadhesivity.

Characterization of the microsphere was done by FTIR. All the formulations showed

good sustained release compared to the pure drug. The drug release data obtained were

extrapolated by Zero order, Higuchi, First order, Korsmeyer-Peppas and Hixson-Crowell

equations to know the mechanism of drug release from the formulations.

The results showed a good fit in Zero order model and Korsmeyer-Peppas model.

The R2 value ranges from 0.910 to 0.981 for Zero order model and for Korsmeyer-Peppas

model R2 values range from 0.887 to 1.00 and coefficient of determination n values range

from 1.044 to 1.926.

Kinetic modeling of in vitro dissolution profiles revealed the drug release mechanism

ranges from diffusion controlled or Fickian transport to anomalous type or non-Fickian

transport, which was only dependent on the type and amount of polymer used. The drug

release followed both diffusion and erosion mechanism in all cases.

The simulation of kinetic modeling on drug release from controlled drug delivery

systems was done. Development tool used for simulation was Microsoft Visual Studio 2005.

The platform used was C# .Net Framework. Simulation could be used to predict the release

kinetics before the release systems are realized.

Key words: Micro-particulate drug delivery, mucoadhesivity, simulation, sustained release.

Abstract

Polytetrafluoroethylene (PTFE) is a remarkable membrane material. Due to its high

melting point, PTFE fine powder cannot be processed using the conventional melting

processing methods. Instead, techniques such as paste extrusion, rolling and sintering have to

be employed.

The water vapor transport properties of polymer membranes are critical in applications of

waterproof breathable clothing materials. Several test methods are available for measuring

the permeability of polymer membrane or laminates but they are either time-consuming or

require large amounts of sample. A new test apparatus was devised for determining the water

vapor permeability of polymer. Additionally, the water vapor transport behavior of the PTFE

membrane does not depend upon the water content in the polymer.

Unsintered PTFE films were uniaxially stretched using Universal Testing machine at

a speed of 100 mm/sec and sintered in the stretched position by blowing hot air of

temperature 3700C over it for 5 minutes and cooled down to room temperature. Sequential

biaxial stretching of PTFE film has been done by first stretching in transverse direction and

sintered in the stretched position and then stretched in longitudinal direction and sintered

similarly as mentioned above. MVTR of both uniaxially and biaxially stretched films was

determined by inverted cup method and the MVTR was found to be 4500 g.m-2.24 h-1 for

uniaxially stretched and 5075 g.m-2.24 h-1 for biaxially stretched film as per ASTM E 96.

These high values of Moisture Vapor Transmission Rate (MVTR) show good breathability of

the films and are quite suitable for using as a waterproof breathable moisture barrier

membrane for fire protective suits.

In addition, we describe a precision PTFE stretch operation with asymmetric heating

system, and how it can be used to improve the properties of PTFE membrane. Different

stretching ratio (none and 50%), asymmetry heating temperature (420oC), and different

heating time (5 and 10 s) were used to modify the PTFE membrane pore size. It was found

that a higher stretching rate tends to result in larger pore size and broader pore size

distribution at the same heating time. At a shorter heating time and without stretch at

asymmetric heating process, the porosity of PTFE membrane was increased from 50 to 70%

and the mean pore size was decreased from 0.15 to 0.08 mm.

Key words: PTFE membrane films, WVTR, Different stretching ratio.

Abstract

A semi-fluidized bed is characterized by a combination of packed bed or fixed bed at

the top and fluidized bed at the bottom within a single contacting vessel. Such a bed has

advantages of both packed and fluidized beds. Various authors including Fan and Wen, G. K.

Roy and Ho et al. have studied the hydrodynamic, mass transfer, reaction kinetics of Semi-

fluidized beds. In the present study hydrodynamic characteristics viz. pressure drop of a co-

current gas-liquid-solid semi-fluidized bed have been studied using liquid as continuous

phase and gas as discrete phase. Experiments have been conducted in a 100 mm ID, 1.8m

height vertical Perspex column using air, water and glass beads in order to develop a good

understanding of each flow regime in gas-liquid-solid semi-fluidization. It is found that

pressure drop increases with increase in particle size, expansion ratio and superficial gas

velocity. The minimum liquid semi-fluidization velocity increases with particle size, bed

expansion ratio and decreases with superficial gas velocity.

Abstract

A kinetic investigation of the slurry phase epoxidation of styrene with hydrogen peroxide

has been carried out, for the first time, over nanoporous Mn(III)salen catalyst, in a batch

reactor, in the temperature range 303-348 K. It was found that product selectivity and rate of

reaction are greatly influenced by concentrations of styrene and hydrogen peroxide. Kinetics

studies reveal that the mechanism of the reaction is of the “Redox” type. The rate equation, r

= k1 k2 POPH / (k1 PO + k2 PH) deduced, assuming a study state involving two stage oxidation-

reduction process, presented the data most satisfactorily for conversion of styrene to styrene

oxide. A tentative mechanism of the process has also been suggested.

Abstract

Carboxylic acids are organic acids characterized by the presence of at least one

carboxyl group. Glycolic acid is a mono carboxylic acid having wide variety of uses such as

in textile industries, as preservative in food & in cosmetics etc. In the synthetic

manufacturing recovery of acid is essential. Reactive extraction is a closed loop process and

with proper combination of extractant and diluent could bring intensification in removal of

glycolic acid from dilute solutions. Quaternary amine could be cheap and effective extractant

for recovery of glycolic acid owing to their ability to extract acid under both acidic and

neutral pHs. For elucidation of various parameters effects on the reactive extraction of

glycolic acid, Aliquat 336 was used with xylene, MIBK and ethylene chloride as diluent

respectively. Aliquat 336 was used in volume percentage of 10-30 % in various diluents. A

tremendous increase in degree of extraction was obtained in all the cases when compared

with physical extraction. Data on equilibrium extraction were given in terms of distribution

coefficient (KD), degree of extraction (E%) and equilibrium complexation constant (KE). KE

was obtained to be 1.306, 0.875 and 1.484 l/mol when 30% Aliquat 336 was used in xylene,

MIBK and ethylene chloride respectively. When comparing the diluents in the acids

investigated are found a striking difference between MIBK and xylene while ethylene

chloride on the other side gives maximum extraction.

Abstract

Ionic liquids (ILs) are a group of new organic salts that exist as liquids at a low

temperature (<100 ◦C). An important feature of ILs is their immeasurably low vapor

pressure. For this reason, they are called „green‟ solvents, in contrast to traditional volatile

organic compounds (VOCs). ILs have many attractive properties, such as chemical and

thermal stability, non-flammability, high ionic conductivity, and a wide electrochemical

potential window.

This Paper summarizes recent applications of ionic liquids (ILs) as „green‟ solvents in

extractions of a variety of substances, including metal ions, organic and bio- molecules,

organosulfur from fuels, and gases. ILs could also be used along with another „green‟

technology, supercritical fluid extraction (SFE), for a more effective separation of products

from ILs. In addition to their environmentally-benign feature, ILs have other favourable

properties over organic solvents used for extraction, such as adjustable hydrophobicity,

polarity and selectivity.

Abstract

Alumina-zirconia composite materials were produced with different acid ratios by the

sol-gel method using aluminum isopropoxide and zirconium chloride. The composites were

produced by changing acid ratio in alumina. The composite materials were calcinated at

600°C, 900°C and 1300°C. The effects of acid concentration and calcination temperature on

the surface area and pore radius were determined from the nitrogen adsorption isotherm at 77

K. The density of the composites was also measured. The minimum density of produced

material was recorded as 1.35 g cm-3

at an acid ratio of 0.2. The highest specific surface area

and pore diameter of the lightest material are 191.86 m2 g

-1 and 18.4 Ǻ, respectively.

Although pore diameter and specific surface area are not changed at any of the experimental

temperatures which were tested by decreasing acid ratio, the density is slightly increased.

However, it was observed that the calcination temperature significantly affects the surface

area and density of the material.

Abstract

Heat exchangers have several industrial and engineering applications. Techniques for

heat transfer augmentation are relevant to several engineering applications. In recent years,

the high cost of energy and material has resulted in an increased effort aimed at producing

more efficient heat exchange equipment. The Augmentation techniques are broadly classified

into three categories – Active, Passive and Compound. In active techniques, external power is

used to facilitate the modification, while passive technique do not require any direct input of

external power and when any two or more techniques are employed simultaneously, then it

comes under compound techniques. The study consist of the effect of concentric conical ring,

full length twisted tape, the twisted tape with spacing and twisted angles on the heat transfer

coefficient. The work also reported for the present studies going on in this field.

Abstract

Two types of equilibrium and non-equilibrium stage models are generally used to

simulate the mass transfer of packed distillation column. Using non-equilibrium model

requires the calculation of mass transfer coefficients, thus, usually equilibrium-based methods

are preferred to be used for simulations of distillation columns.

In this paper, packed column distillation of production of Mono Ethylene Glycol in FARSA

SHIMI Company (Assaluyeh - Iran)‟s Ethylene Glycol portion has been simulated through

using the equilibrium model and solving the related equations. The simulation has been

carried out in the MATLAB environment. The column also has been simulated in the Aspen

Hysys and Aspen Plus ver.2006.5 environments. Then, the output has been compared with

software results, designing and operating data of the underlying columns which demonstrate

good consistency with the model. Having the model validated, the effect of some operating

parameters has been analyzed through the model.

Abstract

Now a day, the important development in the industry is that many traditional

chemical processing techniques are reaching their optimum performance while consumers

demands stretch and governmental regulations tighten. The central starting point is the

knowledge of chemical process, which causes activation of the reaction or deterioration of the

quality of the products with knowledge of the behavior of reactions. Under external

influences, it is possible to accelerate processes and to reduce the chemical usage. Some of

the major reaction types are Photocatalytic (UV), Microwave and Ultrasonic assisted

Abstract

Several diesters compounds were synthesized from commercially available castor oil

derived acid derivatives and common fatty acids. The key step in the three step synthesis of

oleochemical diesters entails the formation of acetylated capryl hydroxy stearate with

different fatty acids (dihydrostearic acid, myristic, palmatic, stearic, oleic, linoleic acids)

through selection of the suitable reactants such as 12-hydroxy stearic acid, capryl alcohol (2-

octanol) and p-toluenesulfonic acid (ptsa) as one of the acid catalyst for esterification and

further acetylation of capryl hydroxy stearate with acid anhydride to form diester. All of these

produced compounds are liquid except 12-hydroxy stearic acid are solids. The diester formed

from the reaction mass was monitored by verifying its pH, temperature. The characterization

analysis revealed that tested parameters, which include moisture content, specific gravity at

25‟C, refractive index at, 25‟C, acid value, saponification value and iodine value of

respective diester, were within the standard specifications. The identity of products was

characterized by GC and TLC. The results showed that increasing chain length of the mid

chain ester and in the end-chain ester had a positive influence on the high temperature

properties of diesters In fact the value obtained for the ester formed indicates that the ester

could certainly be used as emollients. The diester was compared with Isopropyl Myristate

which is one of the best emollients in terms of spreadability test.

Keywords: Castor oil derivative, esterification, acetylation capryl hydroxy stearate,

acetylated capryl hydroxyl stearate, diesters, Isopropyl myristate, spreadability test,

Abstract

This article mainly deals with recovery of CS2, which is entrapped inside the fibre in

spinning section of the Viscose staple fiber plant. The fiber enters a specially designed closed

rectangular box called the “recovery trough”, where a jet of steam under high pressure and

temperature is passed uniformly at different points to vaporize the CS2 entrapped in the fiber,

which is then allowed to flow upwards through a conical shaped vent to the scrubber and then

to the condensation system, consisting of optimally designed heat exchangers for the

condensation of CS2.

Various improved designs for more recovery were analyzed and the best suggested

design is being discussed. These design models are suitable even during drastic climatic

changes. Recovery of more CS2 from the spinning means results in lower emission rates and

exposure to the operator. Carbon disulphide (CS2) that escapes in the spinning section is very

expensive to recover and hence allowed to escape into the atmosphere. The new recovery

trough has been provided with automatically adjustable and porous baffles to maintain

required pressure inside the trough. This method is relatively cheap and safe for the recovery

of CS2.

Abstract

Experimental reactor was a cylindrical bubble-column made of glass, with an inside diameter of 11cm and a height of 26.3(cm). The column was equipped with the sparger type of perforated plate with the porosity. In this study, liquid phase and gas phase were water and air respectively. Gas hold up, bubble size and effect of sparger type in different gas velocity were investigated. Gas hold up was determined with differential pressure method and used to estimate the transition velocity in slurry bubble column reactors. The results showed that with increasing the superficial gas velocity, the total gas hold up increases. Also perforated -type sparger increases the diameter of bubbles up to 35% and decreases gas hold up to about 40% respectively. Also it was found that the Hikitas correlation predicts the gas hold up value better than other presented correlations in this system.

Abstract

This article deals with the total steam and energy analysis of the Acid Plant section of

Grasim Industries Limited, Nagda. Heat losses in various components of acid plant are

analyzed. The main product produced in the acid plant section is Sulfuric Acid (H2SO4).

Sulfuric acid is mainly used in the Spin Bath section in the process of VSF production.

Sulfuric acid is manufactured by the latest Double Conversion Double Absorption (DCDA)

technology by burning sulfur in air to form sulfur dioxide, which is then catalytically

converted to sulfur trioxide and absorbed in sulfuric acid in Absorption Towers to get sulfuric

acid.

Heat is generated in Furnace and Convertor due to the exothermic reactions. This

excessive heat is used to produce steam. Main components of acid plant where significant

heat transfer takes place are Melting Pits, Waste Heat Boilers, Heat Exchangers and

Economizers.

The steam generated is used in sulfur melting pits and CS2 plant. The extra steam

generated is sent to Auxiliary plant and other sections.

Based on our observations and readings recommendations are provided on how to

reduce the heat losses and conserve energy.

Abstract

Fluidized catalytic cracking (FCC) gasoline normally contains n-paraffins, i-paraffins,

olefins, aromatics, sulphur and other trace impurities. Thus it has to be treated to obtain

products of desired composition, octane no. , sulphur content, etc. Here we have investigated

and discussed some of the techniques which could prove to be a better alternative to the

currently existing technologies used for the purpose:

use of ZSM-5/SAPO-11 composite zeolite for hydro upgrading FCC gasoline with the

aim of obtaining product having improved gasoline research octane number, high liquid

yield, good desulfurization activity and lower coke amount

controlled carbonizing of zeolites to be used for the separation of light hydrocarbon

mixtures due to size exclusion and differential adsorption properties of the carbonized

zeolite

use of modified nano-scale ZSM-5 zeolite on olefins reduction in FCC gasoline

use of ultrastable zeolite Y (USY), containing a metal in an oxidation state above zero

Abstract

Delayed coking process has generated renewed interest among the petroleum refiners

because of the trend of processing heavy oils in petroleum refineries. Because of the tight

refinery margins, it has become imperative to squeeze out value added products out of the

petroleum residue. In the present work, the coking of Bombay High vacuum residue (BHVR)

which is obtained as a bottom of the vacuum distillation unit from a crude oil of Indian origin

(Bombay High) was investigated. The experiments were carried out in the batch reaction

mode in the temperature range of 430-475C and at a pressure of 0.2 MPa in an autoclave

bomb reactor. The reaction time was varied in the range of 5 to 90 minutes. A comparison

between the coking behavior of BHVR which forms one of the major commercial feedstocks

of Indian Origin with that of Arabian Mix vacuum residue (Sawarkar et al., 2007) has been

sought. The reaction mixture was quantified in terms of gas, distillates, coke, and

unconverted vacuum residue. The coke yield was found to be significantly lower for BHVR

vis-à-vis Arabian Mix vacuum residue while that of liquid product yield was found more than

that for Arabian Mix Vacuum Residue under similar operating conditions.

UTILIZATION OF DAIRY WASTE SCUM FOR THE PRODUCTION

OF BIODIESEL AND GLYCERIN

Pravin Kasture, A.N. Sawarkar





Abstract: Milk production in India is about 150 million tons per year and is expected to increase

in the future in view of the increasing demand. Large dairies usually have number of

equipments for handling, processing, storage, packing and transportation of milk and

associated products. It may be pointed out that huge quantities of water are used for

housekeeping, sterilizing, and washing equipments and during this process residual butter and

associated fat which are washed get collected in effluent treatment plant as a scum. This scum

causes direct as well as indirect operational difficulties for effluent treatment and hence is a

notorious waste for the dairy industries as it causes disposal problems. The present work

investigates the feasibility of the utilization of this dairy waste scum from milk industry for

the production of biodiesel and glycerin. The dairy waste scum was procured from a dairy

situated in Sangamner, Dist Ahmadnagar, Maharashtra. KOH was used as a catalyst for the

transesterification process. The effect of temperature, methanol to oil ratio, and reaction time,

and agitation were investigated. The fuel properties viz., specific gravity, viscosity, flash

point, pour point, and distillation characteristics for 90% of the biodiesel recovery were

studied. Except for pour point which was found to be higher vis-à-vis petroleum diesel, the

other properties were quite comparable and some even better than the properties petroleum

diesel. The present analysis confirms that biodiesel from dairy waste scum is quite suitable

with recommended fuel properties as per ASTM standards. This way for using dairy waste

scum reduces the cost of production of bio-diesel as it is obtained from the non-edible oil as

well as the problems related to the disposal of dairy scum.

Abstract

Nicotinic acid (3-pyridine carboxylic acid) is widely used in the food, pharmaceutical

and biochemical industries. Fermentation technology (enzymatic conversion of 3-

cyanopyridine) for the production of nicotinic acid in particular has been known for more

than a century and acid have been produced in aqueous solutions. Reactive extraction for the

recovery of the organic acids by a suitable extractant has been found to be a promising

alternative to the conventional processes. In the present work extraction studies for the

recovery of nicotinic acid organophosphorus solvating extractant (TBP) was carried out. A

comparison with the extraction efficiency of pure diluents alone was also studied at same

temperatures. Equilibrium data that is essential for the design of extraction process was

obtained. Physical extraction was studied using simple hydrocarbons such as ketone,

kerosene oil and alcohol. These solvents could not provide high distribution of the acid.

Studies on chemical extraction of nicotinic acid was done and various parameters such as

effect of initial acid concentration, effect of diluent, effect of extractant type and effect of

extractant composition on extraction degree were investigated. Solvation numbers and

equilibrium constants between water and nicotinic acids were also determined.

Abstract

Biodiesel is a renewable, environmentally friendly substitute for petroleum-based

diesel fuel. It is produced from vegetable oils, animal fats, or wastes cooking oils and fats,

and can be used in existing diesel engines without any expensive modifications. Biodiesel can

also be added to petroleum diesel to create a biodiesel blend with favorable performance

attributes and environmental benefits roughly proportional to the biodiesel fraction. Biodiesel

is safe, nontoxic, biodegradable, and reduces the emissions of many harmful compounds

associated with the combustion of petroleum-based diesel. Because biodiesel is produced

from domestically produced plant oils or waste fats, switching from petroleum-based diesel

to biodiesel decreases dependence on foreign petroleum, reduces net greenhouse gas

emissions, and provides tangible benefits for the domestic economy.

This paper describe the biodiesel analyze the social, political, and economic factors

that have prompted people to consider replacing petroleum-based diesel with biodiesel, and

explore the potential for biodiesel adoption in India. Public and private fleet vehicles

represent a particularly attractive market for biodiesel, especially in the India, although future

demand is dependent on public policy decisions. Since one of the key values provided by

biodiesel is the regional nature of its production.

Abstract

Production of hydrogen from renewable energy sources offers a great potential for

CO2 emission reduction, responsible for global warming. Among renewable energies,

liquid biofuels are very convenient hydrogen carriers for decentralized applications such

as micro-cogeneration and transports. Ethanol, produced from sugar plants and cereals,

allows a reduction of more than 60% of CO2 emissions in comparison to gasoline.

BIOSTAR is an R&D project, co-funded by the French Agency for Environment and Energy

Management (ADEME) which aims at developing an efficient source of hydrogen from

bioethanol, suitable for proton exchange membrane fuel cell systems. The objectives are

to obtain, through catalytic process at medium temperature range, an efficient conversion

of bioethanol into pure hydrogen directly usable for PEMFC. CETH has developed a

catalytic membrane reformer (CMR), based on a patented technology, integrating a steam

reforming catalyst as well as a combustion catalyst. Both catalysts have been developed

and optimized for membrane reactor in partnership with the University of Poitiers. The

composite metallic membrane developed by CETH allows hydrogen extraction near the

hydrogen production sites, which enhances both efficiency and compactness.

Abstract

Microreactor technology (MRT) has been receiving increasingly more attention

during the recent decades. Microreactor, having characteristic length scale in the sub-

millimeter range, is a very promising device to be used for various small scale favoring

applications such as for distributed hydrogen production. Small size is favorable for many

reasons. In addition to compactness and lightweight micro-scale reactors provide, several

other advantages compared to conventional reactors have been perceived. They are safer to

use, have higher heat and mass transfer rates and simplified scale-up, to name a few. Besides,

higher selectivity‟s and/or yield can be attained for a number of reactions.

In the context of distributed hydrogen production, microreactors can serve as

reformers, for instance. This review is actually concerned with microreactors and their

potential applications for onsite hydrogen production using a steam reforming (SR)

technique. This review is concerned with SR of both methanol (SRM) and ethanol (SRE)

since these fuels have great advantages over other more common fuels such as methane or

gasoline. Most importantly, these two alcohols can be reformed at lower temperatures

compared to high temperature methane or gasoline reforming thus allowing higher

efficiencies. Moreover, bio-ethanol, which can be converted from biomass, is an extremely

attractive fuel to be used in SR to produce hydrogen as it allows zero net gas emissions to the

air.

Abstract

In the unsafe horizon of pollution, global warming, and energy crises, all resulted

owing to the fossil fuels, hydrogen fuel obtained by steam reforming of bio-derived ethanol

(bioethanol), can be a potentially strong candidate as a clean energy carrier based on the

renewable sources of energy. In this paper, the key issues related to this steam reforming of

bioethanol for hydrogen production are discussed in the view of potential applications for

polymer electrolyte membrane (PEM) fuel cell. Need for the development of catalyst for CO

free production of hydrogen is emphasized to obtain a commercially viable bioethanol steam

reforming system; also the commercial feasibility of hydrogen production is discussed. The

design challenges in bioethanol steam reformer to operate at high pressure and issues related

to membrane module operation are discussed. Moreover, acknowledging the critical

importance of distributed power devices and systems, we foresee the development of

bioethanol based distributed hydrogen production device by steam reforming of bioethanol.

A great deal of enthusiasm is currently noticeable for synthetically derived fuels from

the fossil sources. Notable among such fuels are the diesel, gasoline and jet fuel for which

fairly well developed commercial manufacturing processes are in place. A more recent

addition to this family of sulfur free, near-zero aromatics synthetic fuels is dimethyl ether

(DME), which is considered an excellent substitute for conventional diesel and liquefied

petroleum gas (LPG).Asian Countries particularly china, India, Japan And Koreawith

theirhighest expected energy consumption rates are showing great interest in DME as these

countries are large consumers of diesel, DME has involed interested as an environmentally

being fuel.

provide aprotective layering on the metal surfaces toavoid corrosion. Lubricating oils are

preparedby blending different viscosity-based oils withsuitable proportion of additives. Base

oils areeither derived from crude oil or are syntheticmaterial manufactured by chemical

processes.Re-refining of used lubricating oil is anintelligent option for any country, more so

forIndia, as it would conserve both the naturalresources as well as foreign exchange. It

wouldalso make us near self-reliant in lube oils.In this paper, an attempt has been made

Abstract

The oxidation behavior of Fe-Cr-Al alloys containing 10% chromium and aluminum

in the range of 2 - 8% by weight in pure oxygen at 1 atmosphere pressure at higher

temperatures under cyclic conditions (3 hour cycles) has been studied. In metallographic

investigation, healing layers of Cr2O3 and of Cr2O3/a -Al2O3 could be observed after

breakaway of the initial protective alloy in case of the 2%Al and 4%Al alloys but the 6%Al

and 8%Al alloys reformed external a -Al2O3 scales at all the temperatures and develops a

convoluted configuration. It is postulated that lateral growth results from the formation of

oxide within the existing oxide layer by reaction between oxygen diffusing inward down the

oxide grain boundaries and aluminium diffusing outward through the bulk oxide. The scales

developed on the four alloys maintain more or less good contact with the alloy and thicken

more slowly in case of 2%Al and 4%Al alloys. These effects can be associated with the

reduction in the rate of transport of chromium across the scale in case of 4%Al and 6%Al

alloys and with formation of intergranular and internal oxides in the underlying alloy

substrate.

Abstract

Ultra-low-sulfur diesel (ULSD) used to describe diesel fuel with substantially lowered

sulfur content. The combination of ULSD with advanced emission control technologies is

sometimes called clean diesel. Almost all of the petroleum-based diesel fuel available in

Europe and North America is of a ULSD type. The move to lower sulfur content is expected

to allow the application of newer emissions control technologies that should substantially

lower emissions of particulate matter from diesel engines. This change occurred first in

the European Union and is now happening in North America. New emissions standards,

dependent on the cleaner fuel, have been in effect for automobiles. ULSD has lower energy

content due to the heavy processing required to remove large amounts of sulfur from oil,

leading to lower fuel economy. Using it requires more costly oil. Concerns about the world's

oil supply and ever-rising fuel prices have brought a renewed focus on diesel's superior fuel

economy. Because of their unique engine design, diesel engines are typically 20-40% more

fuel-efficient than comparable gasoline engines. The transition to clean diesel will have a

definite impact on future consumer choices, as automakers formulate strategies and introduce

new passenger vehicles to take advantage of this shifting market. The cleaner diesel fuel

program significantly reduces sulfur content, creating immediate health benefits, and

allowing engine manufacturers to begin using advanced emissions control systems that

further reduce harmful emissions. Currently, the vast majority of ultra-low sulfur diesel is

produced from petroleum. However, biodiesel (along with some emerging advanced fuels) is

inherently ultra-low sulfur and could help meet ULSD requirements in the future. Ultra-low

sulfur content in diesel fuel is beneficial because it enables use of advanced emission control

technologies on light- and heavy-duty diesel vehicles.

Keywords: Ultra-low-sulfur diesel, emissions standards, clean diesel, biodiesel.

ethanol still age. With the skyrocketing price of vegetable oil, there is much interest in

algaculture, which is farming algae to harvest for making biodiesel, bioethanol, biogasoline,

bio-methanol, biobutanol and other bio-fuels. Microalgae have the potential to become a

major global renewable fuels source, beneficially utilizing sunlight, carbon dioxide and

nutrients to rapidly grow long chain hydrocarbons (lipids). These procedures have been

refined through bench-scale extraction tests and batch processed pilot plant trials and

validated through collaboration with leading entities in the private and public sectors.

Another best alternative source of energy is the energy obtained by fusion of

hydrogen atoms. Nuclear fusion is the process by which multiple atomic nuclei join together

to form a single heavier nucleus. It is accompanied by the release or absorption of large

quantities of energy. It has been accompanied by extreme scientific and technological

difficulties, but has resulted in progress. Fusion power would provide much more energy for

a given weight of fuel than any technology currently in use, and the fuel itself (primarily

deuterium) exists abundantly in the Earth's ocean: about 1 in 6500 hydrogen atoms in

seawater is deuterium. An important aspect of fusion energy in contrast to many other energy

sources is that the cost of production is inelastic.

Abstract

Process intensification consists of the development of novel apparatuses and

techniques that compared to those commonly used today, are expected to bring dramatic

improvements in manufacturing and processing, substantially decreasing equipment size,

production capacity ratio, energy consumption and ultimately resulting in cheaper,

sustainable technologies.

Waste water produced from many industries such as sugar, dyeing, textile, mineral

processing and food processing industries is either reused after being treated by conventional

treatment methods or pumped to drainage systems without treatment. This represents serious

environmental problems and causes challenges to the countries which face water shortage.

Old waste water treatment processes were facing the problems with increased capacity needs

as well as the variety of constraints for their disposal processes.

Membrane technology is one of the separation or water treatment use now a days. The

potential applications of the combination or coupling of membrane technology with aerobic

digestion could be utilized for treating waste water coming from different operations of sugar

industry such as mill house, process house, boiler house, cooling pond to level suitable for

direct reuse, safe discharge to surface water bodies and for the drinking pourse. Advantages

of the process include good control of biological activity, high quality effluent free of

bacteria and pathogens, smaller plant size, and higher organic loading rates. Also effective

removal of nitrates, herbicides, pesticides, and endocrine disrupting compounds may be

achieved by this process. Combination also reduced the capital cost, operating cost,

construction cost of aerobic digester and retention time. Thus this combination is referred as

"Process Intensification".

Abstract

The chemical industry handles a variety of raw materials to convert them into

industrially useful chemicals. Millions of industrial accidents occur every year. In this

accidents large no. of workers lose their lives every year in the world. Accidents may cause

injury which may sometime result in death or certain displacement. The significance of

Safety & Health in chemical industries has been a vital issue in achieving productivity and an

edge in the competitive world. Small quantities of dangerous goods can be found in most

workplaces. Whatever they are used for, the storage and use of such goods can pose a serious

hazard unless basic safety principles are followed. In chemical industries the process

conditions depends on parameters like temperature, pressure, flow, etc. if the control

elements of these parameters fail then it causes loss of control of the process which may

result in an emergency situation and if it is not controlled immediately then it may lead to

disaster. It can cause collapsing of equipments or leakage of hazardous chemical or an

explosion or a fire. There should be proper control of elements and systems which control the

operating parameters, such as hot water supply, cooling water supply, refrigeration system,

instrumentation, air supply, blower system, fees pump, etc. The purpose of this Industrial

Abstract

Now day‟s Chemical industry is focusing on efficient management of energy. For this

purpose, energy integration design procedure is a very beneficial tool and is an important

phase in determining the cost of preliminary design. The most important equipment in energy

integration is heat exchanger. The networking of heat exchanger gives optimum energy

utilization in chemical industry. The purpose of the Heat exchanger networking is to

maximize heat recovery, thereby lowering the overall plant costs. The heat exchanger

networks deals with two categories: Synthesis of heat exchanger networks with the goal of

designing a structure that provides the lowest total costs, Data reconciliation with the goal of

establishing true performance of the network and identifying correct heat transfer coefficients

for individual exchangers in the network. Heat exchangers network synthesis, generally starts

with the choice of a particular value of the process streams approach temperature, ΔTmin.

Temperature interval, Pinch Analysis and mathematical programming are the technique used

to synthesize optimal heat exchanger networks. In design of HEN first minimum energy

requirement for minimum heating and cooling requirements for a heat-exchanger network

then the pinch range of temperature was indentified. Based on this analysis suitable HEN can

be suggested.

Abstract

In this study, a membrane reactor containing both a H2 selective dense polymeric

membrane and a commercial Cu/ZnO/Al2O3 Low Temperature Shift catalyst was developed

for simultaneous water gas shift reaction and hydrogen separation. The membrane showed

excellent H2/CO2, H2/N2 and H2/CO selectivities and high H2 permeabilities at 210 0C and 5

atmg upstream Auto thermal reformate feed gas pressure. In the water gas shift (WGS)

membrane reactor, the membrane selectively removed H2, one of the products of WGS

reaction, while the commercial LTS catalyst was used to catalyze the reversible WGS

reaction. By removing H2 simultaneously, the reversible WGS reaction was shifted toward

the products so as to achieve about 96% CO Conversion.

Abstract

Heterogeneous catalysis is widely applied in industry due to important advantages it

offers to chemical process in comparision with homogeneous catalysts may be : easy

separation of reaction products from catalyst ,no limitation of reaction conditions , especially

reaction temperature , no corrosion of reactor , regenerable , easy to handle and easy and safe

disposal. There is relatively less studies of solid base catalysts in comparision of solid acid

catalysts. Alkaline earth oxides (MgO,CaO,SrO,BaO) , alkaline oxides (Li2O , Na2O, K2O ,

Rb2O ,Cs2O ), rare earth oxides ( La2O3, CeO , Y2O3 , Nd2O3 , etc) and others such as ThO2

ZrO2 ZnO, CdO are solid base catalysts 1,2

. Types of reactions catalyzed by solid bases are

(1) Isomerization of double bond (H migration): olefins, alkyne, allene, unsaturated

compounds containing heteroatom (s) (2) Additions: hydrogenation, amination, aldol (3)

Decomposition: alcohol, amine, halogen substituted alkane (4) Alkylation: phenol \, aniline

(5) Esterification: aldehyde and (6) Exchange: olefin-D2, H2-D2 1. In the present work ZnO

was chemically modified with appropriate nitrate salts of different elements with varying

amounts (qualitatively and quantitatively) by wet-impregnation, dried at 96 ˚ C using a water

bath and calcined at uniform temperature of 500 ˚

C for 6 h in the muffle furnace. The

modified solids were examined by recording XRD profiles for their modifications (phase

change, if any) and effect of different modification with respect to quantitative addition of

respective solutions is studied for I /I0 of ZnO (wurtzite structure ) . The different inorganic

phases formed were ascertained by JCPDS diffraction files3. The XRD profiles of some

modified ZnO catalysts are presented. Cyclohexanone is an important intermediate because

of its use in the manufacture of ε- caprolactum (via cyclohexanone oxime route) which is

used in as lactam for nylon 6. It finds applications as solvent for cellulose acetate,

nitrocellulose and natural and vinyl resins4.

Cyclohexene (which is formed due to dehydration

of cyclohexanol) is used as an alkylating component and as a stabilizer for high octane

gasoline and also finds applications in the manufacture of maleic acid, hexahydrobenzoic

acid and cyclohexanecarbaldehyde5.

The chemically modified ZnO catalysts are proposed to

study for dehydrogenation of cyclohexanol by vapour phase (eco-friendly) at atmospheric

pressure.

Abstract

Several Mathematical Models have been developed for processes involving Packed

Bed Extraction Column. According to these models, the mass transfer as well as

hydrodynamic processes is important factors for the column performance. Usually, the

mathematical simulation models describing processes in the packed columns are very

complex despite of many simplified assumptions are made. It also needs excessive time to

prepare computer programme to produce simulation data for further analysis. Therefore, an

alternative approach based on Artificial Neural Network is applied to assist in speeding up

the simulation process. This paper presents a new application of Artificial Neural Network

Abstract

Green energy is energy that is produced in a manner that has less negative impact on

environment than energy sources like fossil fuels. The goal of green energy is to create power

with as little pollution as possible as a by-product. The main renewable energy sources are

hydro, biomass (organic matter), geothermal, solar, wind and biofuels.The various bio-fuels

are bio-diesel, bio-ethanol and biomass. The bio-fuels are combustible materials directly or

indirectly derived from bio-mass commonly produced from plants, animals and micro-

organisms but also from organic waste. The bio-fuel may be solid, liquid or gas and include

all kind of biomass and derived products. The bio-ethanol is produced from corn, wheat and

sugarbeet.The bio-diesel is produced from animal fats and vegetable oils such as rapeseed oil,

canola oil, soybean oil, sun-flower oil, palm oil. The gaseous bio-fuels are bio-gas, landfill

gas and synthetic gas.

Bio-fuels replace fossil fuels avoiding GHG emissions. However, large scale

expansion of biofuels could cause the release of GHG emissions.The sustainable energy is

energy that in its production or consumption has minimum negative impact on human health

and the healthy functioning of vital ecological systems. It is accepted that renewable energy

is a sustainable form of energy which has attracted more attention in recent years.More and

more are using green energy sources because it is the only way they can aid the environment.

Green energy is the future of next generation fuels.

UDCT, NMU, JALGAON (425001)

Abstract

Solid wastes such as mill sludge are generated at various rolling mill operations in

steel industry which are collected in process water treatment units close to the rolling mills.

This mill sludge by product contains various size fractions (Top size -1mm) of iron oxides,

moisture and hydrocarbons (oil and greases) from different sources. Generally, non-oily mill

scale containing high iron is being recycled through either briquetting or sintering route

without any difficulties. The majority of oil mill scale produced in steel industry leads to land

contamination. Recycling of mill scale is challenging due to high oil content. The excessive

oil mill scale introduced through the sinter plant could potentially from dioxins, initiate glow

fires to damage the equipment and cause a blue haze in the electrostatic precipitators used to

clean the gases discharge from sintering operations. The oil contaminated mill scale in

sintering making would also cause cracking of hydrocarbon.

Therefore, a techno-economic viable pre treatment process is required to reduce the

oil content before sinter making to recycle the mill scale. This poster shows Supercritical

carbon dioxide (SCCO2) extraction, that approximately removes 80% of oil from steel swaf

during a 60-minute process to produce a batch of recyclable steel, and phosphorous removal

also reacts the required level. This poster also compares with other physical and chemical all

removing processes and proves SCCO2 process as best process.

Abstract

A large range of (used) waste oil can be recycled and recovered, either directly in the

case of high oil content wastes, or after some form of separation and concentration from high

aqueous content materials. Certain types of waste oils, lubricants in particular, can be proceed

allowing for direct reuse. The use of waste oil after treatment can be either a high energy

content, clean burning fuel or a lube base stock comparable to highly refined virgin oil.

The three most commonly used re-refining technologies in respect of aiming at

ensuring optimal product yield, meeting utility and energy requirements, limiting hazardous

chemicals used and waste volumes produced are:

The acid/clay re-refining process

The vacuum distillation/clay process

The vacuum distillation/hydro-treating process (hydro-processing)

Acid clay re-refining process is non eco-friendly similarly other two process are less

economical.

To search an eco-friendly and economical method a research were carried out by

using 1-butanol as solvent in batch reactor at low temperature.

The specific gravity and viscosity reduction were observed for low temperature 1-

butanol treatment. Similarly, decrease in flash point was also observed. From comparison of

re-refined lube oil base stock with low temperature 1-butanol, solvent treated oil; it was

observed that low temperature 1-butanol solvent treated oil follow the required specification.

Abstract

Supercapacitors are expected to have a much longer cycle life than batteries because

negligibly small chemical charge transfer reactions are involved. Electric double layer

capacitor (EDLC) or Supercapacitor uses carbon as the electrodes and stores charge in the

electric field at the interface. It uses either aqueous or non-aqueous electrolyte. It gives high

power density but low energy density. So the next generation electrochemical double layer

capacitor which uses transition metal oxide as the electrode material along with carbon has

been under innovation which is expected to deliver both desirable power and energy

densities.

As per this we consider this easy, fast and well-organized route to prepare the

uniform coating of PEDOT: PSS on carbon nanotube (CNTs) as electrode by template-free

chemical route such as dip coating at room temperature (27 oC) for Supercapacitor. This work

investigated an efficient, short reaction time, neat conditions and cost-effectiveness for CNTs

coated by PEDOT: PSS. The resultant PEDOT: PSS coated CNTs material was characterized

by X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry,

Fourier transform infrared spectroscopy and UV–visible spectroscopy. The electrochemical

capacitance properties of the composite were investigated with cyclic voltammetry (CV),

galvanostatic charge–discharge and electrochemical impedance spectroscopy (EIS)

techniques in the two- or three-electrode cell system. From these studies it is confirmed that

the as prepared coating of PEDOT: PSS on carbon CNTs possesses good electrochemical

properties.

Abstract

Biodiesel is an renewable diesel fuel alternative to petroleum-based diesel fuel.

Manufactured from natural oils such as soybeans oil, non edible seeds oil or animal fat. used

in diesel engines, and provides a cleaner burning alternative to petroleum diesels. The

environmental benefits of biodiesel includes lower exhaust emissions of particulate matter

and greenhouse gases such as CO, CO2, SO2 and contains no sulphur . Another advantage of

biodiesel is that it can be manufactured domestically. In the present study cotton seed oil is

used for production of Biodiesel production. Unsaturated fatty acids / triglycerides present in

any oil are converted into ethyl-methyl ester (Biodiesel) when treated with methanol by

immobilization of microorganism i.e. Aspergillussp. Rhizopus sp.enzyme Lipase have been

extracted which will be more efficient for effective conversion of unsaturated fatty acids into

esters (Biodiesel). BIODIESEL produced have advanced characteristics than conventional

chemical methods of biodiesel production.

Abstract

Chromatography is regarded as an analytical technique employed for the purification

and separation of organic and inorganic substances. UPLC refers to Ultra Performance Liquid

Chromatography. UPLC can be regarded as a new direction for liquid chromatography.

UPLC is a new category of analytical separation science that retains the practicality and

principles of High Pressure Liquid Chromatography (HPLC), while increasing the overall

interlaced attributes of speed, sensitivity and resolution. UPLC with its shorter analysis times,

narrow peak widths and enhanced peak heights has been widely accepted for better and faster

separation. The UPLC technique in chemistry and instrumentation provides more information

per unit of work. This technique uses very fine particles (less than 2.5μm) so decreases the

length of column, which saves time and reduces solvent consumption. The UPLCTM

technology, based on the use of columns packed with 1.7 µm porous particles combined with

higher pressures than those conventionally applied in HPLC, enabled to improve in peak

resolution, sensitivity and speed of analysis. UPLC chromatographic system is designed in a

special way to withstand high system back-pressures. The UPLC system allows shortening

analysis time up to nine times comparing to the conventional system using 5 µm particle

packed analytical columns. This technique is applicable to both radioactive and stable isotope

labeled drug candidates. The application of UPLC resulted in the detection of additional drug

metabolites, superior separation and improved spectral quality.

ABSTRACT

Corrosion is the destructive attack of a material by reaction with its environment. The

serious consequences of the corrosion process have become a problem of worldwide

significance. In addition to our everyday encounters with this form of degradation, corrosion

causes plant shutdowns, waste of valuable resources, loss or contamination of product,

reduction in efficiency, costly maintenance, and expensive overdesign; it also jeopardizes

safety and inhibits technological progress.. Corrosion control is achieved by recognizing and

understanding corrosion mechanisms, by using corrosion-resistant materials and designs, and

by using protective systems, corrosion inhibitors, devices, and treatments. In this research

paper, we shall discuss about the classification and mechanism of corrosion inhibitors, used

in corrosion engineering By definition, a corrosion inhibitor a chemical substance that, when

added in small concentration to an environment, effectively decreases the corrosion rate. The

use of chemical inhibitors to decrease the rate of corrosion processes is quite varied. In the oil

extraction and processing industries, inhibitors have always been considered to be the first

line of defense against corrosion. A great number of scientific studies have been devoted to

the subject of corrosion inhibitors. However, most of what is known has grown from trial and

error experiments, both in the laboratories and in the field. Rules, equations, and theories to

guide inhibitor development or use are very limited.

ABSTRACT

In 2010, the daily global consumption of petroleum exceeded 123 million barrels

resulting in the release of almost 19 billion metric tonnes of carbon dioxide into the

atmosphere1. Consumption is expected to increase steadily over the next 50 years, driven in

part by higher demands in developing nations. An alternative fuel for automotive

transportation is of particular interest and would have a substantial impact on carbon

emissions. Battery and fuel-cell technologies are strong candidates to replace gasoline and

diesel engines. In particular, hydrogen is an attractive energy carrier because it is carbon-free,

abundantly available from water, and has an exceptional mass energy density2. Hydrogen is

stored on surface of material by physorption or weak van der wal forces. Thus, materials with

large surface areas and low densities, such as metal–organic frameworks and certain activated

carbons, are attractive for hydrogen storage applications. We have synthesized a Metal

Organic Framework Copper Triazolate (Cu TRZ) having high surface area and hydrogen

adsorption test were carried out on that material up to 70 bar. Copper triazolate showed good

adsorption capacity of hydrogen.

Abstract

Experimental and theoretical studies were carried out to investigate the performance

of a fluidized bed ion exchange system to remove nitrate. The exchange of nitrate on strong

anion exchange resin (TULSION A-27) was studied in the flow rate range of 2 to 7 L/h.

Nitrate removal was done at five conditions of the expanded bed height (Z). The results

showed that the experimental data can be fitted to Richardson and Zaki equation, and the

comparison between the experimental and calculated terminal velocities showed low relative

error. Solid-liquid fluidized beds (SLFB) are used in industry for hydrometallurgical

operations, catalytic cracking, chromatographic separation, ion exchange, adsorption,

crystallization and sedimentation, etc. However, the packed bed ion exchange process has

some disadvantages such as high pressure drop and bed clogging. These disadvantages can be

eliminated if the packed bed is replaced by a fluidized bed. The purpose of this study was to

investigate nitrate removal in a liquid-solid fluidized bed ion-exchange system. The effects of

operating parameters including liquid flow rate and height of the bed on the removal rate of

nitrate were studied. The experimental data of voidage versus superficial velocity were

successfully correlated using the Richardson-Zaki Equation.

(according to recent studies, plastics can stay unchanged for as long as 4500 years on earth)

product is growing rapidly and the problem is what to do with plastic-waste. The use of

these materials in road making is based on technical, economic, and ecological criteria. The

lack of traditional road materials and the protection of the environment make it imperative to

investigate the possible use of these materials carefully. While building roads, the provisions

based on the parameters that affect the sustainability but at minimum cost. Methodology

includes a combination of collection and analysis of plastic waste and its application for

bitumen modification and other road construction material. There are two different processes

to incorporate waste plastic bags into the bituminous mixes. Two processes were adopted

(1) Dry process:-Mixing the appropriate quantity of dry shredded plastic bags with hot

aggregate prior to production of bituminous mixes at hot mix plant. (2)Wet process:-Blending

of shredded plastic bags & bitumen prior to the production of modified bituminous mixes.

The performance test proved that the fatigue life of road pavement is doubled and the

stability of roads & resistance to rutting and water damages increased.

Key words: plastic, dry process, wet process, bitumen.

Abstract

The world is facing an energy crisis. Industrialization and urbanization have sharply been

increasing energy usage. Reliance on fossil fuels could produce unprecedented environmental

damage. The solution to this problem of finite sources is to utilize renewable energy

resources to the maximum extent possible. With the increasing interest in biodiesel as an

alternative to petro diesel; many have looked at the possibility of growing more oilseed crops

as a solution to the problem of peak oil. There are two problems with this approach: first,

growing more oilseed crops as a solution to the problem of peak oil. There are two problems

with this approach: first, growing more oil seed crops would displace the food crops grown to

feed mankind. Second, traditional oilseed crops are not the most productive or efficient

source of vegetable oil. A recent breakthrough is bio fuel from algae. Algae have the

potential to produce up to ten times more oil per acre than traditional bio fuel crops such

as oil palm. They can survive where agricultural crops can‟t, such as in salt water and on

marginal land. They thrive on a diet of waste carbon dioxide and the nutrients in agricultural

run-off and municipal waste water. And in addition to fuels, valuable co-products, such as

biopolymers, proteins and animal feed can be made during the process. In this paper methods

of cultivation and harvest of algae and the potential of algae as a fuel is described in detail.

Abstract

The present investigation was carried out to study the removal of indigo dye using a

non conventional adsorbent coconut shell. The adsorption isotherm is obtained in batch

reactor. It is found that dye adsorption capacity (pollutant removal efficiency) of a steady

system depends on adsorbent material, pH of solution, adsorbent dose, particle size, initial

concentration, and type of activation. It is observed that, the process uptake followed first

order adsorption rate expression and obeyed Langmuir and Freundlich model of adsorption.

The Langmuir isotherm is best fitted with respect to Freundlich isotherm for the adsorbent

studied.

Abstract

In recent years the consumption of plastics has increased drastically; because of the

fact that is lightweight, does not rust or rot, reuse and conserves natural resource e is the

reason for which plastichas gained this much popularity. Again, plastics save energy and

CO2emission during their use phase .But used of plastics from household and industries are

recognized to be a major environmental problem. Plastics waste s can be classified as

industrial and municipal plastic waste s according to their origins; these groups have different

qualities and proprieties and are subjected to different managementstartles .The municipal

solid waste (MSW) predicts include paper, container‟s, tin cans,plastics, aluminumcans ,and

food scraps ,as well as sewage .MPWs normally remain a part of MSWs as they are discarded

and collected as household wastes. Plastics usually account for about 7% of the total MSWby

weight and much more by volume .IN order to recycle MPWs , separation of plastics from

other household wastes is required .The waste products of industry and commerce include

plastic ,paper, wood, and metal scraps ,as well as agricultural waste products.

ADVANCE SEPERATION TECHNIQUE- REACTIVE DISTILLATION Deepak P. Sondawale, Gaurav R . Mahalle, Amruta V . Ghatre

B.Tech Chemical Engineering Third Year

University Department Of Chemical Technology NMU, Jalgaon

Abstract

The combination of chemical reaction with distillation in only one unit is called

reactive distillation. The performance of reaction with separation in one piece of equipment

offers distinct advantage over the conventional, sequentional approach which involves

designing of eight distillation columns and two reactor ancillary equipment in consideration

with manufacture of methyl acetate. Especially for equilibrium limited reaction such as

esterification and ester hydrolysis reaction, conversion can be increased far beyond chemical

equilibrium conversion due to the continuous removal of reaction product from reactive zone.

This may lead to an enormous reduction of capital and investment cost for manufacturing

processes involving healthy initial investment and may be important for sustainable

development due to lower consumption of resources. Due to complex interaction between

chemical reaction and separation the performance of the reactive distillation column is

influenced by several parameter like and vocation of reactive and non reactive column

section, reflux ratio, feed location throughput.

Abstract

Due to continuous increase in price of fuels, there is a need of alternative fuels which

are more efficient and cheaper cost. This is accomplished by the production Ethanol, is a

"clear, colorless liquid with a characteristic, agreeable odour " and taste, This is the drinkable

alcohol, the active ingredient in beer, wine and spirits.

Ethanol is made by fermenting and then distilling starch or sugar crops such as sugar-

cane, maize, sorghum, and wheat and other grains, or even cornstalks, fruit and vegetable

waste Ethanol fermented from renewable sources for fuel or fuel additives are known as bio-

ethanol. Additionally, the ethanol from biomass-based waste materials is considered as bio-

ethanol. Currently, there is a growing interest for ecologically sustainable bio-fuels. Bio

ethanol production from potatoes is based on the utilization of waste potatoes. Waste potatoes

are produced from 5-20 % of crops as by-products in potato cultivation.

HOW DOES IT WORK?

Ethanol is a very high octane fuel, replacing lead as an octane enhancer in gasoline

.Fuels that burn too quickly makes the engine knock. The higher the octane rating, the slower

the fuel burns, and the less likely the engine will knock. When ethanol is blended with

gasoline, the octane rating of petrol goes up by three full points, without using harmful

additives. Adding ethanol to gasoline oxygenates the fuel adding oxygen to the fuel mixture

so that it burns more completely and reduces polluting emissions such as carbon monoxide.

In this project or paper we tried to produce ethyl alcohol from a potato waste, at a

laboratory scale it was successful and also check all the parameters like pH, pressure,

temperature, purity of product. The waste or bi-product from this process can be further used

in polymer or in paper and pulp industries. we had performed this project in final year

(Diploma In Chemical Engg). From this project or paper we have conclude that the the

ethanol is used as a alternative fuel and says that “ETHANOL- THE FUEL OF FUTURE.”

ABSTRACT

This report review drilling method common to drillers, with an emphasis on oil well

drilling methods. For completeness mention is made of methods tools used in the oil & gas

industry. Natural gas is a relatively clean burning source of energy that is used for electric

generation, heating, cooking and many manufacturing processes. The demand for natural gas

and other energy sources is rapidly increasing as world population grows, the standard of

living rises, and the world economy expands.

While there are many alternative fuels – coal, wind, solar, water, biomass fuels, and

most importantly, conservation and more efficient use of energy – these, by themselves, will

not meet the demand for power in the foreseeable future. Therefore, the demand for natural

gas will continue to rise. Where natural gas is compassion of gas in which the concentration

of H2S will higher upto harmful condition so introducing the first high-pressure Shell-

Paques/THIOPAQ unit to removal of deadly gas H2S from the natural gas. H2S in the sweet

gas is guaranteed to be 4 ppm(v), while the total design amount of sulfur to be removed per

day is approximately 1 ton. Sulfur concentrations were typically 4ppm(v) H2S or lower in the

treated gas and the H2S removal efficiency was always above 99.5%. and this is a biological

process for removing H2S from (high pressure) natural gas, synthesis gas and refinery gas

streams.

Abstract Zinc oxides nanoparticles have been paid more attention for their distinctive

properties. They are extensively used for solar energy conversion, catalysis, in electronics as

gas sensors, cosmetics etc. Paint industry is one of the biggest beneficiaries from zinc oxide

used as pigments and formulation of antifouling coatings in marine sector.

The synthesis of nano zinc oxide by different routes however was associated with

difficulties of regulating particle size distribution and stabilizing this distribution. In present

work there is use of solution spray process, the basis was to control the reaction at molecular

level through contact of reactants (precursor and precipitant) in aqueous solution at highly

atomized level through spray and use of surfactants for preventing the aggregation. Zinc

oxide nanoparticles thus obtain with regulating particle size and stabilization this distribution

and their utilization in antifouling formulation. Microbial growth on a wide variety of

surfaces can produce phenomena such as corrosion, fouling, dirt, smells and even serious

hygiene and health problems. Thus there is a great contribution of zinc oxide nanoparticles in

the development of antifouling coatings.

ABSTRACT

It is proposed to study newer techniques already employed globally for water

purification. Numbers of research papers were studied and following outcome was obtained.

The presence of natural organic matter, organic micro pollutants and pathogens in water are

some of the challenges for water treatment industries. Pollutants are known to cause colour,

taste and odour problems whilst many organic micro pollutants such as polycyclic aromatic

hydrocarbons (PAHs) are carcinogenic and have endocrine disrupting effects. Moreover,

pathogenic contamination of water causes disease outbreaks and this leads to high death rates

globally. It is observed from various papers and experiments conducted therein by

researchers that advanced technology employed for detoxification is much more effective and

easier. They are

1. Membrane Technology

2. Photocatalysis of TiO2 nanocatalyst

This paper attempts to discuss the above two methods of water purification involving the

concept, Objectives and applications which will be widely used as a viable tool in water

treatment process.

Abstract

Petro-diesel fuel has been used as a source of energy since its discovery in early 6th

century. Reserves of petroleum have been extracted since then and these reserves were and

still are not renewable. Increasing fuel demand worldwide, rapid rise of crude oil price,

limited reserve and its effect on environment push scientists to look for a clean and renewable

fuel in replacement of petroleum based fuel. With environmental and energy source concerns

on rise, using agricultural fats and oil as fuel in diesel engine has captured attention.

Biodiesel is clean alternative burning fuel used for vehicles or for different purpose by

blending with various fraction of biodiesel in diesel fuel like e.g. B5, B20

Biodiesel production from algae is a promising technique. Microalgae have the

potential to produce 5,000 – 15,000 gallons of biodiesel per acre per year, biodiesel from

ethanol. The biodiesel fuel has little more cost than traditional with different reasons like less

demand, availability feedstock, the biodiesel produced is more viscous & not used for

vehicles the decreasing of viscosity increases the overall cost & usage of different techniques

for production increases the overall costs of production. The optimization of cost is done by

the proper utilization of the byproduct produce, using the efficient homemade techniques for

production, production from waste oil & maintaining the viscosity. The cost of biodiesel may

be optimized by increasing the demand of biodiesel & it will be increased by the availability

of feedstock, the availability increases by educating people toward usage of biodiesel. The

biodiesel is environmentally friendly fuel compared to traditional.

Abstract

Self-healing materials are a class of smart materials that have the structurally

incorporated ability to repair damage caused by mechanical usage over time. The inspiration

comes from biological systems, which have the ability to heal after being wounded. Initiation

of cracks and other types of damage on a microscopic level has been shown to

change thermal, electrical, and acoustical properties, and eventually lead to whole scale

failure of the material. Polymers and polymer composites have been widely used in

tremendous engineering fields because of their advantages including light weight, good

processibility, chemical stability in any atmospheric conditions, etc. However, long-term

durability and reliability of polymeric materials are still problematic when they serve for

structural application. Exposure to harsh environment would easily lead to degradations of

polymeric components. Comparatively, micro cracking is one of the fatal deteriorations

generated in service, which would bring about catastrophic failure of the materials and hence

significantly shorten lifetimes of the structures.

B.E (Chem Engg.) S.S.B.T.‟S C.O.E.T, Bambhori, Jalgaon


Abstract

Over 85% of all new heat exchanger applications in oil refining, chemical, petro-

chemical, and power generation are accommodated through the use of conventional shell and

tube type heat exchangers. The fundamental basis for this statistic is shell and tube

technology is a cost effective, proven solution for a wide variety of heat transfer

requirements. However, there are limitations associated with the technology which include

inefficient usage of shell side pressure drop, dead or low flow zones around the baffles where

fouling and corrosion can occur, and flow induced tube vibration, which can ultimately result

in equipment failure. This paper presents a recent innovation and development of a new

technology, known as Twisted Tube technology, which has been able to overcome the

limitations of the conventional technology, and in addition, provide superior overall heat

transfer coefficients through tube side enhancement. This paper compares the construction,

performance, and economics of Twisted Tube exchangers against conventional designs for

various materials of construction including reactive metals. Conventional TEMA (Tubular

Exchanger Manufacturers Association) type shell and tube type heat exchangers consist of a

number of round tubes attached to a tube sheet inside a cylindrical vessel, with tube sizes,

tube lengths, and shell diameters varying depending on the requirements of the application.

Heat transfer surface areas can vary from a few square feet to over 25,000 square feet. The

Twisted Tube heat exchanger originated in Eastern Europe and became commercially

available in Scandinavia in the mid 1980‟s. It was developed primarily to overcome the

limitations inherent with conventional shell and tube technology.




FUTURE FUEL WOOD GAS

Final year Diploma student Govt.Poly.Yavatmal


Abstract

Increasing population, deforestation and changing climatic conditions have led to a

decline in the availability of fuel wood in the India. The purpose of this for the fabrication,

installation, and operation of a biomass gasifier unit (i.e., a 'producer gas' generator, also

called a "wood gas' generator) that is capable of providing emergency fuel for vehicles, such

as tractors and trucks, in the event that normal petroleum sources were severely disrupted for

an extended period of time. These instructions have been prepared as a manual for use by any

machine that is reasonably proficient in metal fabrication or engine repair. The process is

based on incomplete combustion of wood: due to lack of air, gases are created: carbon

monoxide they found a new use here due to their adhesiveness. In the filters, gas is purified

(dust and other impurities are removed) and cooled from 250-300oC to 25-30

oC cool gas is

easier to mix with air, the main fuels, hydrogen and methane. Where the gas mixture mixes

with air in a 1:1 ratio and like the gasoline fumes from the carburetor, which is removed,

starts the engine. The gas is not pressurized since the whole process is taking part in a

vacuum environment.

Abstract

This paper highlights on the materials needs of low-energy intensity separation

technologies that could potentially replace high-energy intensity technologies currently used

in large energy consuming processes. Separation technologies covers all manufacturing

industries and account for approximately 4,500 trillion Btu/yr (TBtu/yr), or about 22% of all

in-plant energy. This paper focuses on the existing practices of the four largest energy consuming industries (chemicals, petroleum refining, forest products, and mining), this paper identifies more than 240 TBtu/yr that could realistically be saved by developing new or advanced materials for low-energy intensity separation technologies. The advanced separation

technologies having low-energy separation systems such as Membranes, Extraction,

Sorption, or with hybrid systems that use low-energy technologies to replaces high-energy

systems. All low-energy intensity separation technologies (extraction, adsorption, absorption

and membrane) depend on a material's properties interacting with the chemical constituents

of an industrial stream to perform the separation. The current application of these low-energy

intensity separation technologies to industrial streams has been limited by the material‟s

performance and cost.

Abstract

Pectinases are a big group of enzymes that break down pectic polysaccharides of plant

tissues into simpler molecules like galacturonic acids. Since pectic substances are a very

complex macromolecule group, various pectinolytic enzymes are required to degrade it

completely. Pectinases are one of the most widely distributed enzymes in bacteria, fungi and

plants. Pectinase production occupies about 10% of the overall manufacturing of enzyme

preparations. Pectinolytic enzymes are widely used in the food industry for juice and wine

production. This review describes the microbial pectinase production, characterization, and

the industrial application of this enzyme.

Abstract

Out of various water pollutants, organic pollutants, VOCS & insecticides are today‟s

major concerns due to their growing use in every sector like agriculture, industrial and

domestic and their adverse effects on nature and human being. It is therefore necessary to

reduce or eliminate organic pollutants from water and wastewater. Primary removal methods

include screening, sedimentation, floatation, neutralization, activated carbon treatment. In the

present investigation, the primary objective was to study kinetics of isothermal adsorptive

removal of phenol (organic pollutant) from aqueous phase on commercial (GAC) and surface

modified activated carbon. The activated carbon was selected because it is simple, easily

available, selective, low cost etc. A wide range of phenol concentration i.e. from 500 ppm

and 1000 ppm was chosen for the study. Kinetics of adsorption was presented for three

different modes like Stagnant, stirring and flow conditions. A novel packed bed reactor PW-

PBR was fabricated using plastic waste material (empty gum bottle) to study hydrodynamics

and non-ideality in the reactor performance. Effects of various operating conditions such as

type and %age of loading of transition metal (Fe, Ni, Al) reactor type, flow rate, weight of

adsorbent etc. on phenol removal were studied. The amounts of phenol adsorbed were

determined by breakthrough analysis. The characterization of GAC and surface modified

GAC were performed using BET analyzer. It was found that the removal efficiency and

amount of phenol adsorbed increased with order flow conditions>stirring>stagnant. Fe

loading greater than 10% showed maximum efficiency for isothermal phenol removal in

maximum cases.

CARBON SEQUESTRATION

Pradhnyashree Kose, Shweta Chaudhari

Pravara Rural Engineering College, Loni.

Abstract

Concern about global climate change has led to efforts to find a way to reduce carbon

dioxide emissions. Permanently sequestering or storing carbon dioxide thousands of feet

underground in a semiliquid state is one possible solution that shows promise. Small-scale

research is a very important step in testing the viability of carbon sequestration as a long-term

solution. The MRCSP currently hosts three geologic field tests. More than 20 such tests are

being undertaken nationwide. About 3,000 tons of CO2 will be injected over the course of

several months. This Concern about global climate change has led to efforts to find a way to

reduce carbon dioxide emissions.

The term "carbon sequestration" refers to the sequence of processes whereby CO2

emitted from large-scale CO2

emission sources is separated, recovered, and stored under the

ground or at sea. More specifically, the exhaust gas (mainly from combustion) from large-

scale CO2

emission sources such as power plants and steel mills first undergoes a process of

separation and recovery exclusively for CO2

utilizing chemical reactions or the properties of

CO2. This is followed by transportation to the storage site by pipeline or tanker (the latter

requiring liquefaction). The sequestration is completed with the forced injection of the

transported CO2

into the ground or in the sea.

Recent findings show that the amount of organic carbon stored in high-latitude

permafrost regions has been greatly underestimated. While concerns are rising that thawing

permafrost and resultant CO2 and methane emissions are a positive feedback mechanism at

times of anthropogenic global warming, the potential role of permafrost carbon dynamics on

glacial-interglacial timescales has received little attention.

Abstract

Nanotechnology is concerned with the materials and systems whose structures and

components exhibit novel and significantly improved physical, chemical, and biological

properties, phenomena, and processes due to their nanoscale size. Workforce development is

essential to reap the benefits of nanotechnology development along with technology transfer.

The emphasis should be on hands on educational experiences by developing nanotech

laboratory demonstration experiments that could be adaptable and incorporated into existing

courses in engineering and engineering technology. This paper describes a design that is

developed to demonstrate heat transfer using nano-fluids in a mini heat exchanger utilizing

commercially available equipment. Theoretical heat transfer rates were calculated using

existing relationships in the literature for conventional fluids and nano-fluids. Experiments

were conducted to determine the actual heat transfer rates under operational conditions using

nano-fluids and the heat transfer enhancement determined compared to fluids without

nanoparticles.

Abstract

An in silico technique was initiated to characterize the properties and structure of the

protein. The Calotropis procera proteins analyzed in the study shows that these are linear

proteins .Tools used for in silico analysis are expasy tools such as Protparam for primary

analysis, TCoffee for phylogenetic study, PSIpred secondary structure prediction, Cn3D 3D

structure. 3D modelling of proteins are also done. Most of the studied proteins have half life

30 hours in vitro assay in mammalian reticulocytes. In the present study eight proteins from

the plant Calotropis procera are investigated for in silico analysis. Out of which four proteins

are from expansin family. Expansins proteins characteristically cause wall stress relaxation

and irreversible wall extension. Expansins are also expressed in ripening fruit where they

function in fruit softening, and in grass pollen where they loosen stigmatic cell walls and aid

pollen tube penetration of the stigmain germinating seeds for cell wall disassembly, in floral

organs for their patterning, in developing nitrogen-fixing nodules in legumes, in abscissing

leaves, in parasitic plants, and in „resurrection‟ plants during their rehydration. Expansin

proteins have MW of ~25–28 kDa. The peptidic sequence of an expansin consists a signal

peptide of around 20–30 amino acids at the N-terminal end, the putative catalytic domain, a

His-Phe-Asp (HFD) motif in central region and the C-terminal putative cellulose-binding

domain with conserved Trp (tryptophan) residues. Expression of alpha expansin genes may

be regulated by auxin, gibberellin, cytokinin or ethylene, show a transcription induction by

submergence, where hypoxia and submergence increase α-expansin mRNA levels.

FLARING REDUCTION IN THE CHEMICAL INDUSTRIES

Mr. Swapnil Ashok Ghungrud, Prof. G. S. Zamre


College of Engineering and Technology, Babhulgaon(Jh.), Akola-444104

e-mail:- [email protected]

Abstract

Flaring is a combustion process used to dispose of large volumes of combustible

gases including natural gases (sweet gas, sour gas, acid gas or other hydrocarbon vapor)

through a vertical stack. Facilities in the oil and gas industry may routinely flare small

volumes of natural gas that are technically difficult and uneconomic to conserve. Flaring is

also an important safety measure, used to safely dispose of natural gas that would otherwise

pose a hazard to workers, nearby residents and facility equipment during non-routine

occurrences like emergencies, process upsets, equipment failure and power failure conditions

. The burning of valuable gases with the help of additional energy resources in flare stacks

and the destruction of valuable energy resources remain widespread in the world. World

gross production of natural gas rose 3.7% in one year ( in 2007 it was 3,717.9 bcm to 3,854.4

bcm in 2008) . At the same time flaring losses again increased in 2008, going to almost 134

bcm, an annual rise of 4.6%, and now represent 3.5% of the total volume produced. More gas

is flared in Nigeria than anywhere else in the world. The gas industry statistics publisher,

Cedigaz, indicates that Nigeria accounted for 19.79% of global flaring in 2001, more than the

second ( Iran ) and third ( Indonesia ) countries combined.

Incessant demand in energy led to rise in oil and gas production and increased unusual

flaring at various operations. The flaring of gases generates various harmful organic

chemicals, NOx, SO2 and CO, CO2. Environmental pollution, global warming and climate

change issues emerged from the increased flaring. In order to reduce CO2 emission GGFR

has supported at least seven demonstration projects to obtain carbon credits from flaring

reduction projects in major flaring countries. It is going to be necessary for all stakeholders to

step up efforts if flaring reduction is to have a higher impact. If all major contributors of gas

flaring work together and follow flare minimization either by recovery or by reduction, this

will drive the world towards zero flaring worlds.

Abstract Neem oil extraction from Neem seeds (*Azadirachta indica A. Juss*) using hexane

with the help of soxhlet apparatus is presented. Effects Neem seeds are extracted using

hexane solvent with ratio of neem seed powder weight to solvent volume of 1:5. Here we

have studied the yield of oil. Based on the analysis, showed that decreasing particle size

increases the yield of oil and increase in temperature increases the yield of oil. Values of

Density, flash point, saponification value of oil are found in oil testing.

We used mass transfer kinetic model to represent our project data because there is no

reaction between the Neem oil with solvent hexane. Neem oil as an organic material contains

several organic compounds such as nimbin, nimbidin, salannin, etc. Since Neem oil is an

organic material, it readily dissolved in organic solvents like hexane. Here, the mechanism

control for extraction of Neem oil in hexane is mass transfer, and we propose mass transfer

kinetic model to represent the yield data of Neem oil extraction.

Abstract

Our whole world seem to be wrapped in plastic. Plastics are used almost everywhere

like shopping bags, kitchenware, automobile industry, agriculture mulch etc, and also find

various medical applications. Traditional plastics are manufactured from non-renewable

resources like oil, coal and natural gas which will get depleted in near future. It is estimated

that world -wide production of petroleum based plastic is around 100 million tonnes annually

and 7 million barrels of petroleum are required per day to produce that plastic. That is why

the need arrived to produce biodegradable and echo-friendly plastic which can easily

manufacture from natural sources and also it should not be hazardous to environment. For the

past several years, the producers of raw agricultural commodities have suffered from low

prices and surpluses because of reduced demand and increase world supplies. Recently

efforts have been made to reverse the trend by converting agriculture commodities into value

added product. For eg.corn was grown in 1970‟s mainly for livestock feed but today it is

being used increasingly to produce high fructose corn syrup, fuel alcohol and other non food

products.

So the both were favourable to the invention of biodegradable plastic from corn starch

.the process mainly consisting of the conversion of raw corn to starch first, then this corn

starch is fermented with the help of appropriate enzymes reaction yielding the lactic acid

,lactic acid is produced commercially by the fermentation of glucose, molasses of cheese

whey with homofermentative lactic acid bacteria .Some of the strains like Rhizopus oryzae in

surface culture converted D glucose in a chemically defined medium to a large amount of

L(+)- lactic acid .the conversion of lactic acid to the polylactic acid is taking place via lactide

through polycondensation reaction. The biodegradable plastic is provided with a function

and performance as ordinary plastic used. The biodegradable plastic can be converted into

useful items by conventional processing technique like Thermoforming.

Abstract With the continuously increasing population and rapid industrial development, there

is a need for environmentally sustainable energy sources. Bioethanol is an attractive

sustainable energy source to fuel transportation (ethanol from biomass).Bioethanol can

contribute to a cleaner environment and with the implementation of environmental protection

laws in many countries; demand for this fuel is increasing.

Current ethanol production (so called first generation) using crops such as sugarcane,

corn and wheat is well established. Whereas second generation ethanol production utilizes

cheaper and non-food feed stocks like lignocelluloses or municipal solid waste which could

make ethanol more competitive to fossil fuels. Lignocellulosic biomass has been recognized

as promising resource for the production of Bioethanol due to its abundance, low cost and

non-competitiveness with foodstuffs, and is having high contents as cellulose, hemicelluloses

and lignin.

There are various physical, chemical and biological methods for production of

Bioethanol from lignose cellulose followed by fermentation of sugar obtained by enzymatic

hydrolysis of lignocellulosic biomass. Production of ethanol from lignocelluloses requires a

more complex upstream process compared to first generation ethanol production. While there

are ongoing efforts to further enhance properties and delignification with optimization of

underlying process of production or saccharification process using bio-technology. The

positive result of substrate “Lantana camara” was recently found in India. Lantana camara is

a non-edible lignocellulosic biomass growing widely throughout India.

Hence second ethanol production generation is the need of the hour.

Abstract

The minerals and metallurgy industries face one of the most serious environmental

issues as regards the treatment of aqueous or oily effluents. The major pollutants that come of

out of these industries include residual reagents, powders, chemicals, metal ions, oils, organic

and some may be valuable (Au, Pt, Ag). The use of flotation has emerged as one of the key

options due to the high throughput of modern equipment, low sludge generation and the high

efficiency of the separation schemes already available. This technology offers, in most cases,

advantages over settling, filtration, precipitation, or adsorption onto natural and synthetic

adsorbents. The targets are the removal of oils (emulsified or not), ions (heavy metals and

anions) and the reuse or recirculation of the process waters. Advantages include better treated

water quality, rapid start up, high rate operation, and a thicker sludge. New applications are

found in the mining vehicles washing water treatment and reuse, AMD (acid mining

drainage) neutralization and high rate solids/water separation by flotation with micro-

bubbles. It is concluded that this process will be soon incorporated as a technology in the

minerals industry to treat these wastewaters and, when possible, to recycle process water and

materials. In the present communication, the application of flotation in environmental

applications in the context of minerals and metallurgy industries is discussed at length.

Examples of promising emerging techniques and devices are reported and some recent

advances in the treatment of heavy metal containing waters and emulsified oil wastes are

discussed.

ABSTRACT

In natural convection applications, the components used for cooling may represent a

significant portion of the overall weight of the system. Consequently, advanced materials are

of interest in such applications, as they may substantially reduce the total size and the weight

of the system.

The APEX 2000, an Advanced Process Enhancement exchanger, utilizes proven

FBHX Technology to provide a cost-effective and timely solution to severe heat exchanger

fouling problems. Many of these advanced materials have anisotropic thermo physical

properties, hence the control of thermal conductivity is crucial. This work is motivated to

address the lack of understanding of the use of anisotropic advanced materials in natural

convection environments. Numerical simulations are carried out to test the performance of

heat sinks made of such materials and comparisons are made with the heat sinks of traditional

engineering materials under the same conditions. The results demonstrate that the total

weight of the system may be reduced drastically with the use of advanced materials relative

to the most commonly used heat sink materials at the same thermal performance. Total

resistance, conduction and convection resistances, and a performance related FOM values for

each heat sink are presented. It is shown that pyrolytic graphite based heat sinks show the

best thermal performance, while Carbon- foam heat sinks offer tremendous performance due

to the material's low density.

IF you are facing severe heat exchanger fouling problems . And have made the

decision to Take Action to Eliminating Fouling, you may want to consider one of the APEX

2000 Test Units which are available on a lease basis. These short term, low budget test units

are offered to provide for an on-site evaluation of a specific application of the FBHX

Technology. Typical Applications among 50 Installations in Europe, the U.S., the U.K. and

Iceland.

Abstract Green Chemistry is also named as Sustainable Chemistry. It is a philosophy of

chemical research and engineering. It encourages the design of products and processes,

reduces the use and generation of hazardous substances. The concept of Green Chemistry was

proposed by Paul Anestas in year 1994. Green Chemistry encourages the redesign of existing

industrial processes that reduce or eliminate the generation of hazardous byproducts.

Chemists and Chemical engineers use the knowledge and practices in chemistry to design

chemical products and chemical processes to serve the needs and wishes of society by

concerning the laws of health and the environment. The purpose of these laws is to promote

the principles of Green Chemistry and Engineering to reduce the impact of chemical waste on

environment. To illustrate, we consider here some features of polylactic-acid production and

the significant advantages of a “green” polymer relative to other polymers made from

petroleum. It is almost impossible to get 100% conversion in any process as waste materials

are also produced. These waste materials are always disposed in environment. The animal

and human populations are exposed to these waste materials which may be harmful to health

or may lead to environmental degradation. Green Chemistry and Engineering provide a way

to overcome environmental degradation. The main goal of chemical profession is to

manufacture chemical products for society. Therefore it is essential that these products and

their method of manufacturing will minimize harm to the environment. How Green

Chemistry is essential for chemists and chemical engineers is discussed in this article. Keywords: Green Chemistry, Hazardous substances, pollution, environmental degradation.

Abstract

Nanotechnology is poised to play a significant role in the development of clean, less

expensive energy. The potential of nanotechnology for solving some of today‟s greatest

energy challenges is vast. The recovery of unconventional sources of natural gas is yet

another potential application of nanotechnology. Unconventional sources of natural gas

include tight sandstones, shale gas, and coal bed methane. Nanotechnology applications may

prove useful in accessing or exploiting these unconventional natural gas sources. The

interaction of nanoparticles and mineral grains or fluid interfaces in the reservoir is a new

field of research. We can inject a certain volume of nanoparticles with specific characteristics

into a well and by analyzing the nanoparticle concentration from an observation well we learn

about the geology and reservoir characteristics. In this case, the nanoparticles act as tracers.

Ferromagnetic nanoparticles can be injected into the well bore prior to petrophysical well

logging. The injected particles enhance well-log readings and yield better measurements

about the reservoir properties. Because of their large surface area to volume ratio, new

nanoparticle-surfaced proppants are being developed that could enhance the effectiveness of

hydraulic fracturing treatments.

Abstract

Heat pipes are very flexible systems with regard to effective thermal control. They

can easily be implemented as heat exchangers inside sorption and vapour-compression heat

pumps, refrigerators and other types of heat transfer devices. Their heat transfer coefficient in

the evaporator and condenser zones is 103– 105 W/m2 K, heat pipe thermal resistance is

0.01–0.03 K/W, therefore leading to smaller area and mass of heat exchangers.

Miniature and micro heat pipes are welcomed for electronic components cooling and

space two-phase thermal control systems. Loop heat pipes, pulsating heat pipes and sorption

heat pipes are the novelty for modern heat exchangers. Heat pipe air preheaters are used in

thermal power plants to preheat the secondary–primary air required for combustion of fuel in

the boiler using the energy available in exhaust gases. Heat pipe solar collectors are

promising for domestic use.

This paper reviews mainly heat pipe developments in the Former Soviet Union

Countries. Some new results obtained in USA and Europe are also included.

Abstract

In the past, the values of ionic liquids thermophysical properties were found to have

significant effect on the design of physico-chemical processing and reaction units by

influencing directly the design parameters and performance of equipments. The influence of

actual errors in the thermophysical properties of ionic liquids can render any future design as

not working or excessively costing. Nanoparticle Enhanced Ionic Liquids (NEILs) are a new

and innovative class of heat transfer fluids which exhibit fascinating thermo physical

properties compared to their base ionic liquids. NEILs formed by the dispersion of nanometer

sized solid particles, rods or tubes for example Single-walled nanotubes (SWCNTs), multi-

walled nanotubes (MWCNTs) and fullerenes (C60, C80, etc.), opens in traditional ionic

liquid. This paper deals with analysis of the most important thermal properties for an optimal

technological design of process plants, namely thermal conductivity and heat capacity of

ionic liquids and ionanofluids, from experimental data to molecular modelling of heat

transfer and storage in these types of systems. Ionic liquids based on Cnmim cations and

(CF3SO2)2N, BF4, PF6 anions are used to illustrate the most important behaviours Results

on thermal conductivity and heat capacity of ionanofluids as well as the estimation of heat

transfer areas for ionanofluids and ionic liquids in a model shell and tube heat exchanger

reveal that ionanofluids possess superior thermal conductivity ranging from 2 to 35%, and

heat capacity and require considerably less heat transfer areas as compared to those of their

base ionic liquids. Based on experimental results, it is concluded that Nanoparticle Enhanced

Ionic Liquids are novel class of fluids which shows great potential for advanced heat transfer

applications.

Abstract At present era, there is enormous increase in newer formulations, chemicals, drugs,

and so on. So there is need of assuring safety and efficacy of these products with standard and

advanced analytical testing. Hyphenated techniques suggest the better option for the fast,

accurate analytical testing. Amongst them, LC-MS is widely used separation technique now

days. Liquid chromatography produces pure or nearly pure fractions of chemical components

in a mixture and Mass spectroscopy produces selective information such as, molecular weight

for identification using standards or library spectra. In LC- MS methods, analytes are

separated, detected directly from molecular characteristics as molecular mass and molecular

disintegration patterns. LC-MS/MS today holds enormous potentials for improvements in

laboratory medicine mainly in therapeutic drug monitoring, endocrinology, toxicology,

analyses and food analysis. In this paper, the recent advances in LC-MS method, its

methodology and its applications in various fields are reviewed.

Abstract

Green Chemistry is a philosophy of chemical research and engineering, that

encourages the design of products and processes that minimize the use and generation of

hazardous substances. In 1990 the Pollution Prevention Act was passed in the United States.

This act helped to create a modern operation for dealing with pollution in an original and

innovative way. It aims to avoid problems before they happen.

As a chemical philosophy, green chemistry applies to organic chemistry, inorganic

chemistry, biochemistry, analytical chemistry, and even to physical chemistry. While green

chemistry seems to focus on industrial applications, it does apply to any chemistry choice.

The term green chemistry was coined first by Paul Anastas in 1991.Paul Anastas, then

of the United States Environmental Protection Agency, and John C. Warner developed 12

principals of green chemistry, which help to explain what the term means in practice. The

principals cover the concepts as:

# The design of processes to maximize the amount of raw material that ends up in the

product

# The use of safe, environment-benign substances, including solvents, whenever

possible

# The design of energy efficient processes

# The best form of waste disposal: not to create it in the first place.

In this Paper we'll be discussing the first principal of green chemistry i.e. It is better

to prevent waste than to treat or clean up waste after it is formed. Attempts are being made

not to only quantify the greenness of chemical process but also to factor in other variables

such as chemical yield, the price of reaction components, safety in handling chemicals,

hardware demands, energy profile and ease of product workup and purification. Green

chemistry is increasingly seen as a powerful tool that researchers must use to evaluate the

environmental impact of nanotechnology.

Abstract

Word moves on energy. A fluctuation in supply and price of energy imparts bad

effect. Like air, water and food, man needs energy in different forms. Energy has always

played an important role in human and economic development and in society well-being.

Without the heat and electricity from fuel combustion, economic activity should be limited

and restrained. Modern Society uses more and more energy for industry, services, homes and

transport .This is only true for oil, which has become the most traded commodity and part of

economical growth is linked to its price.

Fuel is a substance burned as a source of heat or power. The heat is derived from the

combustion process in which carbon and hydrogen in the fuel substance combine with

oxygen and release heat .The provision of energy as heat or power in either mechanical or

electrical form is the major reason for burning fuel.

Mostly we used non-renewable energy source for electricity generation and other

purposes.This fuel create carbon dioxide and various toxic gases which is harmful to the our

environment as well as it is limited on the earth so we would have to find out clean fuel for

future i.e hydrofuel. This seminar related to fuel cell and hydrogen technology.This seminar

include introduction to fuel cell, basic structure of fuel cell, reforming of hydrogen,

renewable energy system, biological method for hydrogen production.It also contain benefit

and obstacle to the success of fuel cell and the development of hydrogen based economy.

Abstract

A biochemical fuel cell is a device which converts chemical energy into electrical

power. The catalysts used in this process can be either inorganic or organic type giving rise to

'inorganic fuel cells' or 'biochemical fuel cells', respectively. Biochemical fuel cells use either

microorganism or enzymes as active components to carry out electrochemical reactions. The

efficiency of such a device theoretically can be as high as 90%. The difficulty in attaining

these values arises due to sluggishness of electron transfer from active site to conducting

electrode. This can be overcome by using mediators or by immobilizing active components

on conducting electrode. We have immobilized fad-glucose oxidize on a graphite electrode

using a semiconducting chain as a bridge. At the present stage of development, such a device

tacks high current densities, which is essential for commercial power generation but Can Be

used in applications such as pacemakers and glucose sensors.

STEVIA: PROSPECTS AS AN EMERGING NATURAL SWEETENER

Abstract

In the last couple of decades, growing concern about health and life quality has

encouraged people to exercise, eat healthy food and decrease the consumption of food rich in

sugar, salt and fat. Omission of added sucrose in foods increases the relative proportion of

polymeric carbohydrates that may have beneficial effect for a balanced food intake as well as

for human health. In addition, there has been an increase in the demand by consumers for

food with functional properties. Changes in eating habits and lifestyle are mainly due to

incessant search for health.

In the past, food science was concerned with the development of food for human

survival, a goal that was substituted by the concept of production of quality food. More

recently, the main concept has become to use food as a means of promoting health and

welfare, while reducing the risk of disease . The food industry has responded to this demand

and as a consequence, there has been a fast growing increase in diet foods and beverages

available to consumers in many markets of the world. With increased consumer interest in

reducing sugar intake, food products made with sweeteners rather than the sugar have

become popular. Sweeteners are alternative substances to sugars, which give food a sweet

taste and are used to partially or totally replace sucrose. The discovery of great number of

sweeteners during the last decade has triggered the development of sugar free products,

particularly for diabetic, obese people and for dietetic purpose. Sweeteners such as nutritive

(Polyols) and nonnutritive/ intense sweeteners (Artificial and natural) have become

alternatives to replace sucrose and have been widely used in various food products. Natural

sweeteners are mainly plant constituents. Plants have contributed to about 75 highly sweet

compounds.

These sweet compounds fall mainly within the terpenoid, flavonoid and protein

compound classes, although altogether nine districts structural groups of potently sweet

molecules have been derived from plants. So far, highly sweet compounds have not been

documented as these occurred in lower plants, insects or native organisms and the taxonomic

distribution of plants, known to biosynthesize highly sweet compounds, is random within the

angiosperm super order as classified according to Dahlgren. Several highly sweet plant

constituents are used commercially as sucrose substitutes in one or more countries. The plant

secondary metabolites of most widespread interest in this regard are Steviol glycosides i.e.

Stevioside and Rebaudioside A, constituents of the Stevia rebaudiana bertoni. These two

products, made from S. rebaudiana are widely available in Japan, with Stevioside approved as

a sweetener in Brazil and having limited use in Korea too. In India, the use of artificial

sweeteners in food products has not been very common so far when compared with the

majority of western countries. However, over the past decade, there has been a steady

increase in many Indian retail foods that are labeled as „diet‟ and /or „light‟. Contrary to the

situation on the late 1980s when only people with health problems (e.g. diabetes or high





blood cholesterol) used to buy these products, many Indians have now started to consume

low calorie foods and are eating less sugar and fat as part of their main diet. Given the

reasonably sound track record of plant constituents and particularly S.rebaudiana (Stevioside

glycoside) as “Intense” sweetening agents and because of the great public demand for natural

food ingredients, particularly for diabetic and dietetic applications, FSDU, PFA has worked

on the prospects of Steviol glycosides as sugar substitute.

This comprehensive document on S.rebaudiana have included aspects for legal

regulations of various countries, marketing and economic issues, status of stevia in India,

commercial extraction, practical application of Stevioside in foods and beverages stability

and Organoleptic studies , estimation of Stevioside when present in food or other samples. As

well as botanical field and literature studies, chemistry, toxicological, mutagenicity,

pharmacological properties, electrophysiological and behavioral methods for natural

sweetener detection using Mongolian Gerbil and Cariogenicity study on Stevioside and

Abstract

As the industrial water contains some toxic compounds, small amounts of refractory

organic pollutants , such as anionic surfactants, small amount of heavy metals , such as cupric

and chromic ions and large amounts of sodium salts, ammonia, nitric acid, acetic acid and

many more. These compounds are harmful to human body and also the eco-systems.

But one of these waste nitric acid is having harmful effects on human beings like

Asthma, corrosive to eyes, mouth, stomach skin, dilute nitric acid causes mild skin irritation

and give painful burn to skin. To remove such toxic compounds, the Adsorption method is

applied. These can be applied by using different media such as activated carbons, saw dust,

Abstract In the 21

st Century as the population has grown to a greater extent, there is a rise in

the number of paper mills in the market. Today‟s industrial environment is competitive, it is

well known fact that paper mill wastes like lignin causing enormous destruction and

producing negative impacts on national economics. Though it is almost impossible to fully

recoup the damage caused by lignin, it is possible to minimize the potential risks. Lignin is

main factor of environment pollution.

The residue from combustion of pulverized coal that is waste by product from thermal

power station is known as fly ash, (pozzolana). Although it is not a cementitous, it combines

with lime to form a material having cementing properties. The aim of this project is to study

the removal of lignin from paper mill wastes using fly ash as an adsorbent and to compare the

suitability of these two materials with activated charcoal.

The use of such technique would result in a number of benefits not only it would

provide either controlling lignin waste strength but it will also provide valuable empirical

data for the improvement of treatment on lignin and further protect environment with the use

of unproductive waste fly ash.

Nowadays many paper industries are faced with the problem of wastewaters being

badly biodegradable because of tannins, lignin etc. removal of lignin by fly ash may prove as

an appropriate method for the destruction of very complex, multi-dimensional, and

permanent compounds and lignin. This project studies the removal of lignin water as a model

case with the aim of removal of lignin and enhancing water biodegradability also separated

turbid lignin.

The discharge of highly colored effluents by Kraft pulp and paper mills is a major

environmental concern. A process utilizing fly ash to treat Kraft effluents has developed in

this study.

Abstract

Membrane bioreactors (MBRs) can replace the activated sludge process and the final

clarification step in municipal wastewater treatment. Membrane bioreactor (MBR)

technology, which combines biological-activated sludge process and membrane filtration has

became more popular, abundant, and accepted in recent years for the treatment of many types

of wastewaters, whereas the conventional activated sludge (CAS) process cannot cope with

either composition of wastewater or fluctuations of wastewater flow rate. MBR technology is

also used in cases where demand on the quality of effluent exceeds the capability of CAS

Along with better understanding of emerging contaminants in wastewater, their

biodegradability, and with their inclusion in new regulations, MBR may become a necessary

upgrade of existing.

In recent years, applications of membrane separation techniques in wastewater treatment

have drawn worldwide attention to researchers and engineers. The membrane bioreactor

(MBR) process, which consists of an activated sludge bioreactor and a microfiltration

membrane, is an emerging biotreatment technology that has demonstrated a great promise in

water reuse. It has the advantage of the rapid development in membrane manufacturing and

the potential to fundamentally advance biological treatment processesing technology in order

to fulfill the legal requirements in wastewater treatment plants.




BAMBOO BASED BIODEGRADABLE PLASTICS

[email protected]

Abstract

Past ages of human society have been called the Stone, Bronze, Copper, Iron, and

Steel Ages, based on the material that was relied upon the most during that time. Today, the

total volume of plastics produced worldwide has surpassed that of steel and continues to

increase. Without a doubt, we have entered the Age of Plastics.

The plastics are made using non-renewable products such as petroleum products etc.

And the use of plastics continues to grow, raising the important question: how can we balance

convenient living with concern for ecology? There is a new generation of biodegradable

plastics emerging, bioplastics. The plastics that are biodegradable are made mostly or entirely

from renewable sources. The non-renewable sources should be replaced by renewable sources.

Bamboo based plastics are important not only because bamboo is least expensive but because its

high strength, biodegradability and low cost. The biodegradable plastics can be made by using

natural fibers such as jute, sisal etc.

This paper deals with what are plastics, how are they harming our earth, why

biodegradable plastics, how are they processed. If society is indeed becoming more and more

committed to resource conservation, environmental preservation, and sustainable

technologies, biodegradable plastics will find their place in this Age of Plastics.

Abstract

Switchgrass (Panicum virgatum L.) shows potential as a sustainable herbaceous

energy crop from which a renewable source of transportation fuel and for biomass-generated

electricity could be derived. Switchgrass can be used as a fuel source to power ethanol plants,

which results in reduced use of fossil fuels and contributes to a more positive energy balance

for cellulosic ethanol. Switchgrass is a native warm-season, perennial grass indigenous to the

Central and North American tall-grass prairie into Canada. The plant is an immense biomass

producer that can reach heights of 10 feet or more. Its high cellulosic content makes

switchgrass a candidate for ethanol production as well as a combustion fuel source for power

production. A technique for regenerating switchgrass plants via tissue culture has been

proven and new population of regenerated plants have been established in the field. Research

on the physiology of switchgrass has shown that lowland and upland ecotypes differ in

photosynthetic rate but not in respiration rate. Findings in each of these areas can contribute

to development of switchgrass as a sustainable bio-energy crop.

Abstract Utilization of renewable energy sources such as biomass offers environmental

benefits while providing sustainable power generation for utilities and industry. It offers

markets for dedicated energy crops such as switch grass, while providing needed energy for

power generation, thereby offsetting or reducing the need for fossil fuels. In areas where

fossil fuels are scarce and biomass fuels are available, biomass. Utilization offers alternative

low cost methods for power generation. Gasification of biomass, rather than combustion,

offers efficiency, environmental, and operational advantages including the ability to use the

producer gas in fuel cells. The producer gas composition from this gasifier will be used in a

fuel cell power plant simulation study.

Biomass gasification means incomplete combustion of biomass resulting in

production of combustible gases consisting of Carbon monoxide (CO), Hydrogen (H2) and

traces of Methane (CH4). This mixture is called producer gas. Producer gas can be used to run

internal combustion engines (both compression and spark ignition), can be used as substitute

for furnace oil in direct heat applications and can be used to produce, in an economically

viable way, Fuel cells convert hydrocarbon fuels to electricity at efficiencies exceeding

conventional heat engine technologies while generating extremely low emissions. However

under present conditions, economic factors seem to provide the strongest argument of

considering gasification. In many situations where the price of petroleum fuels is high or

where supplies are unreliable the biomass gasification can provide an economically viable

system – provided the suitable biomass feedstock is easily available.

Contact ID: [email protected], [email protected]

Abstract

As the Environmental and health issues are taken into consideration there is a need

for the development of efficient and low cost technology for controlling air pollution. One

of the technology is Bio-oxidation, which is “the process based on microbes that can

remove both water-soluble and non-water soluble emissions from the air when it is passed

through the Bio-oxidation system.” Biological technology solutions are advancing as a

technology of choice for odour control and Volatile Organic Compound (VOC)/

Hazardous Air Pollutant (HAP) control of air emissions.

The efficiency of the bio-oxidation system is based on the medium that is used for

the growth of microorganism. There are various bioactive media such as soil , peat or

compost which are used to biodegrade contaminants present in air. In these bioactive

media biodegradation rates were low. To solve this problem two or more technologies are

combined which includes combination of bio-trickling filter and biofilter. In bio-trickling

filter synthetic media such as ceramic or plastic is used in which biodegradation rates are

high and in biofilter compost media is used. Combination of these two biofilters gives

better results.

Bio-oxidation systems don‟t require fossil fuels to provide the air for bio-oxidation

and there is no need to heat the device. So a company can save upto 66% on their

maintenance cost and on their pollution control costs.





BIOCHAR- A WAY FORWARD TO WORLD

Mr.Nazim Quazi, Mr.Tushar Khadasne

Abstract

Biochar is a fine-grained, highly porous charcoal that helps soils retain nutrients and

water. Biochar is found in soils around the world as a result of vegetation fires and historic

soil management practices. Intensive study of biochar-rich dark earths in the Amazon (terra

preta), has led to a wider appreciation of biochar‟s unique properties as a soil conditioner.

Biochar can be an important tool to increase sustainable food production in areas with

severely depleted soils, scarce organic resources, and inadequate water and chemical fertilizer

supplies. Biochar also improves water quality and quantity by increasing soil retention of

nutrients and agrochemicals for plant and crop utilization. More nutrients stay in the soil

instead of leaching into groundwater and causing pollutionThe carbon in biochar resists

degradation and can sequester carbon in soils for hundreds to thousands of years. Biochar is

produced through pyrolysis or gasification processes that heat biomass in the absence (or

under reduction) of air.

Not only this, but also it is a good adsorbent of CO2 thus it can be used to reduce

atmospheric CO2 and thus helps in global warming control.




OCEAN THERMAL ENERGY CONVERSION

Mr.Suhas D. Doke, Mr.Shrikant k.


Anuradha Engineering College, Chikhli. Maharashtra, India .

Abstract

Oceans and seas which cover about 70% of earth are constantly receiving solar radiation

and act as the largest natural solar collector. An ocean as a collector has an enormous storage

capacity Energy from the ocean is available in several forms, such as ocean thermal energy,

wave energy, tidal energy.

Ocean thermal energy conversion (OTEC) is new technology needed to be

harnessed especially in India where the coastline is about 6000 km. Basically, the OTEC

converts the thermal energy, available due to a temperature difference between the warm

surface water and the cold deep water, into electricity.Power from the OTEC is renewable

and Eco-friendly. An OTEC plant can operate in remote Island and in sea-shore

continuously.It is very low grade solar thermal energy, so the efficiency of energy recovery is

quite low. However, since the ocean thermal energy is dispersed over a large ocean surface

area, it has a big potential.According to Ministry of natural and renewable resource(MNRE),

the over all potential of ocean energy in the country in excess of 50,000 MW, there is an

enormous opportunity to tap this renewable source of energy

ADULTERATION OF FUEL

NMU, Dist.- Jalgaon-425001.


Abstract

The blending of kerosene with automotive diesel is generally practiced by oil industry

worldwide as a means of adjusting the low temperature operability of the fuel. This practice

is not harmful or detrimental to tailpipe emissions, provided the resulting fuel continues to

meet engine manufacturer‟s specifications. High level adulteration causes increase in

emissions, as kerosene is more difficult to burn than gasoline. Adulterating of diesel with

kerosene is common malpractice since kerosene is cheaper than diesel. Such adulteration

results in increased pollution, reduced lifetime of components, decrease in engine or machine

performance etc. There are number of techniques used to detect adulteration like use of

markers, gas chromatography etc.

Five fuel-adulterant mixtures in different proportions by volume were prepared and

individually tested for density and kinematic viscosity. Many vehicles seldom maintained

properly run on adulterated fuels. An assessment of the extent of emission represented by

opacity value and fuel quality tests with varied composition of fuel (diesel) and adulterant

(kerosene) proportions in diesel. The usefulness of density and kinematic viscosity tests

applied to different proportional mixtures of fuel and adulterant and also to assess variation in

opacity value (k-value) of emission from combustion of adulterated diesel (kerosene in

diesel) consequent to the extent of adulteration.

Keywords: Adulteration, gasoline, kinematic viscosity.

Abstract

Environmental and human safety concern has become determining factors in chemical

engineering and process development. Currently, there is a strong emphasis On the

development of more sustainable separation processes.In Chemical industries Distillation,

Extraction, Adsorption, etc. are used as separation techniques. But there is a need of

advanced separation techniques. The main goal is to be creative and blend artistic interests

with scientific technology to produce compounds with enhanced properties, eventually

replacing conventionally produced products. The supercritical fluid extraction has been

applied only recently to sample preparation on an analytical scale. It has the potential to be

environmentally friendly “green” processing techniques, and in some cases replacing the

traditional organic solvents based extraction techniques with solvents like supercritical CO2,

ethanol and water. The solvent used in this technique is a supercritical fluid, substance above

its critical temperature and pressure. By controlling the level of pressure / temperature /

modifier the important properties of a SCF via density, viscosity, diffusivity, heat capacity

and thermal conductivity can be varied to make it more feasible. In addition carbon dioxide

which is the most adopted super-critical fluid has low cost in a non-flammable compound and

devoid of oxygen, thus protecting liquid sample against any oxidative degradation. Main

advantages of SCF instead of conventional organic solvents such as achieving high purity

extracts, no residual solvent ,single step processing, reduced operating cost, selective

fractionation, faster separation,eco-friendly,physiologically compatible.It finds application in

natural foods and flavours, pharmaceuticals, polymers, chemicals and equipment cleaning.

Abstract

"Smart" coating systems are engineered to respond to electrochemical processes

responsible for corrosion by providing a self-repairing system. Smart Coatings have long

been used to provide corrosion protection for metals exposed to corrosive environments.

Coatings provide corrosion protection by a number of mechanisms. The most common

mechanism involves the stablishment of a barrier between the environment and the substrate,

breaking the connection through the electrolyte between anodes and cathodes on the surface

of the substrate that is needed to sustain a corrosion reaction. A second corrosion protection

mechanism afforded by some coatings is cathodic-sacrificial protection. Several smart

coating system strategies employ electroactive polymers EAPs) such as polyaniline. These

coating systems capitalize on the two unique properties of EAPs, their ability to: (1) conduct

electricity and (2) bind and expel molecules or ions in response to an electrochemical

potential. For a smart coating system, the switching of the EAP redox state is triggered by

local electrochemical reactions occurring on the surface of a metal which occur during a

corrosion process. Thus, if the EAP is engineered to contain an inhibitor ion as a dopant, the

ion is released when a corrosion process (metal oxidation) occurs. This presentation will

focus on the chemistry of EAPs for corrosion protection of high tensile strength aluminum

alloys such as 2024-T3, which are of great interest in the aerospace industry. In contrast to

pure aluminum, which is resistant to pitting corrosion, the increased susceptibility of the

2024-T3 aluminum alloy to pitting corrosion is centered upon the unique electrochemistry of

the intermetallic inclusions, specifically oxygen reduction reactions (ORR). The goal is to

incorporate organic ORR inhibitors into coating systems that are released upon demand.

Abstract

Biomass gasifier is used for producer gas which is used for thermal and electrical

application. Gasifier can classify into two types i.e. fixed bed & fluidized bed biomass

gasifier .After considering advantages & disadvantages of different type of biomass gasifier it

is found that fluidized bed process have advantages of excellent gas-solid mixing and unifier

temperature within the bed. Presence of dense suspension provides a large thermal inventory

of separator is used for solid capture and recycle in order to extend the solid residence time in

the reaction zone.CFB gasifier operate in either turbulent fluidization or fast fluidization

regime. These features not only improve carbon conversion but also reduce tar yields. In the

past decade intensive R&D activities have been conducted in various institution world wise

on fluidized bed reactors .Although CFB biomass gasification is undergoing rapid

commercialization. Fundamental and pilot scale studies are needed for optimization and scale

up, as well as to fill knowledge gaps in underlying principals.

Abstract

Membrane systems have become a tried and accepted natural gas treating technology

with distinct advantages in a variety of processing applications. Variety of materials was

using for manufacture such type of CO2 removal membrane from natural gas. Although there

are requirement of new research which have been installed onshore, some offshore facilities

do exist, and many more are planned.

Some early installations highlighted the need for suitable preprocessing prior to

membrane treatment. Suitable manpower, energy for treatment, raw material quality is

responsible for CO2 removal from natural gas. This need has led to the development of a

robust and comprehensive pretreatment scheme that ensures extended membrane life.

Pretreatment, in combination with the continuing development of advanced membranes, has

even further enhanced the reliability and performance of membrane technology and made it

the CO2 removal technology of choice in a variety of processing conditions.

Abstract

Thousands of new chemicals enter the market every year on a global scale. The risks

associated with the chemical industry are commensurate with their rapid growth and

development. Apart from their utility, chemicals inherent properties and hazards i.e., they are

flammable, explosive, toxic or corrosive etc. Industrial accidents are disasters that happen in

industrial sites. A lot of industrial disasters have happened since the 19th century. On 3 Dec

1984 leakage of MIC gas at Union Carbide Corporation killed several peoples was one of the

biggest chemical industrial accident ever, which created need for advance safety measures.

Beside from accidental happenings, industrial accidents can also be caused by negligence on

the part of the company or incompetence of personnel. It is important that all safety measures

are implemented in order to have a secure work environment where negligence and

incompetence cannot be blamed for accidents that occur. Although these measures may be

implemented, there may still be accidents that cannot be avoided. Some of these can be

caused by natural disasters that can strike at any given moment. Fukushima Daiichi nuclear

disaster in which there was a series of equipment failures, nuclear meltdowns, and releases of

radioactive materials at the Fukushima I Nuclear Power Plant, following the Tōhoku

earthquake and tsunami on 11 March 2011. It is the largest nuclear disaster since the

Chernobyl disaster of 1986. The significance of Safety in chemical industries has been a vital

issue in achieving productivity and an edge in the competitive world. This abstract is an effort

to present the various factors affecting the safety in chemical industries in recent times and

Abstract

Worldwide, the average baseline consumption of fresh water is 300 liters per day per

person which equals to around one hundred thousand liters of fresh water per person

annually. The demand for fresh water in India will be tremendous, which will be required by

the increased population. Almost 20% of the world's population is facing lack of access to

safe drinking water. Water covers over 75% of the earth surface and saline water makes up

97.5% of this; however just 2.53% is fresh and potable, used for different purposes such as

domestic, industrial and agriculture demands. Based on the latest figures from “World Water

Development Report” more than 50 percent of the nations in the world will face water crises

by 2025, however by 2050 about 75 percent of the world population will have a significant

possibility of facing water shortages. The answer to these water challenges is to find or create

new, alternatives, and inexpensive resources of fresh water. Traditionally dams and artesian

wells have been used in order to provide fresh water; however the amount of water that can

be produced in these ways is insufficient or unpredictable. Therefore creating a new source of

potable water has been a significant issue worldwide.

Desalination could hold the key for new fresh water resources.

Abstract

Heat transfer is defined as the transmission of energy from one region to

another as a result of temperature gradient. Heat transfer found chief applications in

design of thermal and nuclear power plants including heat engines, steam generators,

condesers, internal combustion engines, refrigeration and air conditioning units etc.

This paper presents an experimental comparison of four different types of heat

transfer enhancement techniques or methods in heat exchangers: two insert devices (a

displacement device and a swirl flow device), extended surfaces, and obstruction devices.

Heat transfer processes and the methods and devices that can be implemented to

enhance the heat transfer. The experimental setup and apparatus required to carry out these

experiments are relatively simple. The apparatus includes five tube-within-a-tube heat

exchangers with three thermocouples at each end, two rotameters, a heating element, a water

pump, and a data acquisition device. Four of the five heat exchangers are modified by one

type of the above-mentioned heat transfer enhancement techniques. The equipment is

relatively inexpensive and available in almost all undergraduate heat transfer laboratories.

Abstract

Mixed column is a modified bubble column which is nothing but combination of two

different types of column like bubble column-trickle bed, packed column-bubble column, etc.

Design of bubble column, trickle bed & their internals has been studied separately.

In the present work studies have been carried out on the hydrodynamics of two-phase

gas-liquid flow in a modified bubble column & packed bed column. Where a sparger is used

as gas-liquid distributor, studies have been carried out on gas holdup characteristics and

pressure drop. A model for pressure drop in the modified bubble column based on

mechanical energy balance within the framework of dynamic interaction of the phases has

been formulated. The model includes the effect of bubble formation and foam drag at

interface on the pressure drop. Correlations were also developed to predict the gas holdup and

pressure drop. The experimental data have been found to agree well with the proposed model

and correlation. The experimental results were compared with other system and the overall

performance of the present system has been found to be highly encouraging as a gas-liquid

contactor.

To improve the transfer operation and its efficiency, researchers are trying different

kinds of multiphase contacting devices viz. simple bubble column, bubble column with

internals, trickle bed with different types of packing. The main advantages of two phase up

flow mixed column are large interfacial area available inside the bubble column and surface

renewal take place inside the packed column.

DIMETHYL ETHER – THE NEXT GENERATION FUEL Amolkumar A. Durbude, Omkar S. Pune, Vishal V. Deshmukh

Final year B.Tech Chemical Engineering,

UDCT, NMU Jalgaon

Abstract

DME (Dimethyl Ether, CH3–O–CH3) is an LPG-like synthetic fuel. DME is a clean

burning synthetic fuel that can substitute for conventional diesel, liquefied petroleum gas

(LPG). As a diesel fuel replacement it reduces NOx emissions 90%. It can be transported as a

pressurised liquid similar to LPG. DME can be economically produced from a number of

feedstock like natural gas, biomass and coal. It is gaseous at ambient conditions but can be

liquefied at moderate pressure. With a high cetane number, DME has very attractive

characteristics as an alternative fuel for diesel engines. The properties of DME are similar to

those of LPG. DME can be blended up to 20% with LPG and used for household cooking and

heating, without any modifications to equipment or used as a replacement. DME can also be

used as a clean burning substitute for diesel in transportation and as a clean fuel for power

generation. DME can be manufactured by dehydration of methanol but also by direct

synthesis from synthesis gas. Synthesis gas can be produced from any carbon containing raw

material. Currently, the most economic way to produce synthesis gas is by reforming natural

gas. Large-scale manufacture of DME from natural gas can be cost competitive with diesel

fuel. The synthetic gas is then catalyzed to produce DME. It can be produced by coal. coal is

first gasified to produce a synthesis gas rich in CO and hydrogen. It produces by-products

CO2, methanol and water which are separated from the product DME by distillation.

Methanol is recycled to DME synthesis reactor to be converted into DME. Synthesis gas can

also be produced from biomass, but having a higher cost than from natural gas. By using

biomass as feedstock, the emissions of fossil CO2 can be considerably reduced.

Abstract

With rising urbanization and change in life style and food habits, the amount of

municipal solid waste has been increasing rapidly. The term municipal solid waste refers to

solid from houses, streets and public places, shops, offices and hospitals. The average person

produces almost one ton of wastes per year. In most of the cities & towns the municipal solid

waste is being dumped & burnt in open spaces without understanding the adverse impacts on

the environment. The waste in the dumping ground undergoes various anaerobic reactions

produces offensive Green House gases such as CO2, CH4 etc. These gases are contributing

potentially to Global Warming & Climate Change phenomenon. This mismanagement of

waste will cause serious long term environmental damage.

We can use this municipal solid waste to generate electricity by capturing methane

(landfill gas). Methane is a primary constituent of landfill gas (LFG).Instead of allowing

LFG to escape into the air, it can be captured, converted, and used as an energy source. The

captured methane will be combusted to generate electricity that will feed to the national

power grid and used as an alternative source of cheap and renewable energy that will reduce

dependence on grid power and this will displace fossil fuel based electricity generation.

The benefits of this are that the non-reusable waste is converted into combustible

gases for electricity generation. Utilization of municipal solid waste leading to reduction of

the use of fossil fuel and reduction of GHG emissions.

Abstract

Man has a habit of chewing the chewing gum since ancient times. Today it is one of

the most popular dosage form, used for delivering the many active components. The first

medical chewing gum was introduced in market in 1928 consisting of aspirin an analgesic

drug. Chewing gum can be used as drug delivery for many active components. With the

inclusion of medical chewing gum in the European pharmacopeia in 1998, have further

contributed to the acceptance of this method of drug delivery Many children find it difficult

to swallow tablets. To overcome this problem, liquid formulations have been developed A

chewing gum formulation is an obvious alternative. As chewing gum as a drug delivery

system is to be expanded into additional therapeutic areas, it is important that the delivery

form is acceptable to the end-users Active substances and additives sweeteners like sorbitol

Mannitol and suitable fruity flavors and non sticky Gum Base are used. There are two

methods of evaluation of Chewing gum one is vitro and another is vivo method. based on this

drug delivery of chewing gum is suggested. Prevention and cure of oral diseases are obvious

targets for chewing gum formulations

Abstract

Many refiners find themselves with underutilized FCC capacity while at the same

Time they must cope with stranded streams such as coker naphtha and FCC C4‟s and C5‟s

which have little value as fuel blending stock due to olefin content and Octane issues. This

problem will be aggravated as more cokers come on-stream to convert additional resid

material and as FCC units increase severity to maximize propylene production. It is possible,

however, to upgrade such olefins-containing streams to high-value petrochemicals using

SUPERFLEX™, a commercialized fluid catalytic cracking process, which converts olefins-

containing C4-C8 streams predominantly to propylene, with large quantities of ethylene and

aromatics also produced. In addition, elements of high severity C4 and naphtha cracking can

be integrated into an FCC unit co-processing traditional FCC feedstocks such as VGO using

the MAXOFIN™ FCC Process. This paper provides a general overview of the KBR

SUPERFLEX, ACO and MAXOFIN FCC processes, including discussion of their similarities

to, and differences from, refinery FCC‟s. Information is included regarding the yield

performance of cracking streams such as coker naphtha and FCC C4/C5‟s and the

implications regarding product octane and olefin content.

Abstract

Hydrogen as a high-quality and clean energy carrier has attracted renewed and

ever increasing attention around the world in recent years, mainly due to developments in

fuel cells and environmental pressures including climate change issues. Membranes are also

important to the subsequent purification of hydrogen. For hydrogen production and

purification, there are generally two classes of membranes both being inorganic: dense phase

metal and metal alloys, and porous ceramic membranes.The two key advantages of dense

metal membrane are that is 10 * cheaper than palladium membranes and has 10 * better

performance.Most hydrogen separation membranes operate on the principle that only

hydrogen can penetrate through the membrane because of the inherent properties of the

material. The mechanism for hydrogen penetration through the membrane depends on the

type of membrane. Most membranes rely on partial pressure of hydrogen in the feed stream

as the driving force for permeation which is balanced with partial pressure of hydrogen in

the product (permeate)stream.

Eltron‟s membrane is the separation of hydrogen and carbon dioxide from

gasified-coal.Eltron‟s hydrogen transport membrane system(HTM) is under development for

separation of hydrogen from carbon dioxide in an Integrated Gasification Combined Cycle

(IGCC) power plant designed for carbon capture and storage. Process performance economics

were evaluated for IGCC plants with carbon capture using HTM in comparison with

conventional technology. Detailed process simulations were developed to evaluate the

performance of IGCC plants using conventional technology for the baseline cases, and

comparison cases using the hydrogen transport membrane for hydrogen/carbon dioxide

separation.

occurrence is finite. In concepts for new products, the price, performance, and product safety

criteria are equally important and have a correspondingly high importance right at the start of

product development. To ensure a high degree of product safety for consumers and the

environment, renewable resources have often been shown to have advantages when compared

with petrochemical raw materials and can therefore be regarded as being the ideal raw

material basis. Results from oleo chemistry show that the use of vegetable fats and oils allows

the development of competitive, powerful products, which are both consumer-friendly and

environment-friendly. Recently developed products, which fit this requirement profile, are

the anionic surfactants cocomonoglyceride sulfate and the nonionic sugar surfactant alkyl

polyglycoside. These products are used especially as mild surfactants in cosmetic

formulations. In polymer applications derivatives of oils and fats, such as epoxides, polyoils,

and dimerisations products based on unsaturated fatty acids, are used as plastic additives or

components for composites or polymers like polyamides and polyurethanes. In the lubricant

sector fatty acid based esters have proven to be powerful alternatives to conventional mineral

oil products.

NMU, Jalgaon-425001


Abstract

A homogenous single phase, the supercritical fluid possesses the density and solvating

power of a liquid with the viscosity and diffusivity of a gas resulting in greater extraction

efficiency compared to traditional extraction process. SFE offers exiting opportunities in the

field due to improved quality and purity of extracts, faster extraction times, and reduced

solvent consumption .The main attraction of SFE is the use of carbon dioxide(CO2) as the

solvent as it shows good solvent characteristics like low toxicity, non inflammability ,also it

is not harmful environmentally. It can reach supercritical conditions at pressure 73.8 bar and

temperature 31.3 .It shows applications in various fields like extraction of medical

components from plants, extraction of essential oils, in food industry, in environmental and

soil analysis, extraction of metalloid and metal species from a solid or liquid material.

Beside these advantages SFE requires high capital investment, large numbers of

variables to optimize, and there are some difficulties in scale up. SFE is not a fully mature

technology and needs to be more fully developed in five areas to be successful in tomorrow‟s

environmental lab such as general rugged extraction methods, ease of use, automation, etc.

Enhanced understanding of methods development and a firmer theoretical base will allow

SFE to become an established technique for sample preparation.

Department Of Chemical technology, North Maharashtra University,

Jalgaon-425001


Abstract

Waste heat is heat, which is generated in a process by way of fuel combustion or

chemical reaction, and then “dumped” into the environment even though it could still be

reused for some useful and economic purpose. The essential quality of heat is not the amount

but rather its “value”. The strategy of how to recover this heat depends in part on the

temperature of the waste heat gases and the economics involved. Large quantity of hot flue

gases is generated from Boilers, Kilns, Ovens and Furnaces. If some of this waste heat could

be recovered, a considerable amount of primary fuel could be saved. The energy lost in waste

gases cannot be fully recovered. Usually higher the temperature, higher the quality and more

cost effective is the heat recovery.Recovery of waste heat has a direct effect on the efficiency

of the process. This is reflected by reduction in the utility consumption & costs, and process

cost. Indirect Benefits are reduction in pollution, reduction in equipment sizes, reduction in

auxiliary energy consumption.

Abstract

ZnO nanoparticles have been paid more attention for their distinctive properties. They

are extensively used for solar energy conversion, catalysis, in electronics as gas sensors,

cosmetics etc.

The synthesis of nano ZnO particles by different routes however associated with

difficulties of regulating particle size distribution and stabilization. In present work there is

use of solution spray process, Zinc Acetate ((CH3COO)2 Zn.2H2O) is used as a precursor and

Sodium Hydroxide (NaOH) as a precipitator at room temperature, with varying conc. /type of

surfactant. The basis of this technique is to control the reaction at molecular level through

contact of reactants (precursor and precipitant) in aqueous solution at highly atomized level

by using sprays and use of surfactants for preventing the aggregation. ZnO nanoparticles thus

obtain with regulating particle size and subjected to characterization such as FTIR, AFM and

properties related to gas sensing behavior were performed.

The thin films of ZnO of different thicknesses were deposited onto precleaned

amorphous glass substrate at room temperature and as deposited films are used for

characterization of transport properties. The room temperature and high temperature

resistivity is measured by four probe technique. The bulk resistivity, carrier concentration,

activation energy were evaluated. By using Thermo Electric Power (TEP) measurement the

Fermi energy and scattering coefficient were evaluated.

The results of characterization reveal the feasibility of synthesized nano ZnO in gas

sensing applications.

Abstract

As with all environmental exposures, the potential impacts of hazardous waste

incineration on human health and the environment should be addressed scientifically and

thoroughly. Making a scientifically valid connection between operation of an incinerator and

resulting disease within a population is a difficult undertaking, requiring the combined efforts

of toxicologists, epidemiologists, environmental chemists, physicians, and other disciplines.

Concerns regarding the potential impacts of incineration needed to be addressed and

communicated, both accurately and effectively, if the actual risks of incineration are to

become widely used. This information describes how to control hazardous substances at

work so that they do not cause ill health. It will help you understand what you need to do to

comply with the Control of Substances Hazardous to Health (COSHH) Regulations 2002 (as

amended) which apply to the way you work with these substances me widely understood.

BIO-DENITRIFICATION

Akshay Jakhete, Sayali Titre




Abstract

Elevated levels of nitrate, nitrite, and ammonia have been identified within shallow

soil and groundwater regimes at several places in India. Traditional means of addressing

impacts have proven to be both costly and often ineffective. This has lead to the

development, testing and implementation of techniques for the remediation of fertilizer based

groundwater impacts based on the- Enhanced In Situ Bio-Denitrification (EISBD) principles.

EISBD techniques have been evaluated using bench studies, field based pilot tests and full

scale remediation. It can be concluded that remediation of the fertilizer-based ground water

impacts using EISBD is generally both technically feasible and economical. Important

lessons learned, the process of evaluating and applying EISBD techniques, and the positive

and negative aspects of this remediation option are described herein.



EVALUATION OF VARIOUS ADSORBENTS FOR REMOVAL OF

TOLUENE

Miss. Swati Phalak, Mr. R. S. Sirsam

University Department Of Chemical Technology, NMU. Jalgaon.


Abstract

One of the most common terms used in the solvent industry is volatile organic

compound and is abbreviated as volatile organic compounds. VOCs are a large group of

organic chemicals that readily evaporate at room temperature. VOCs can be defined as

organic chemicals with a vapour pressure of more than 0.1 mmHg at 200C and 760 mmHg,

which participate in atmospheric photochemical reactions.

Many industrial processes handling organic solvents produce VOCs. These VOCs not

only cause environmental pollution, but also represent an economic loss. VOC removal and

recovery have become a big issue that needs to be addressed.

Traditional techniques for VOCs removal include carbon adsorption, condensation,

absorption, but none is efficient enough to meet every need. Membrane separation has

emerged as an excellent alternative or complementary technology for VOC separation.

The development of an advanced VOC destruction process consists of an adsorption

unit followed by an adsorption column. Carbon, zeolite, and polymer adsorbents have each

been used to adsorb VOC and other pollutants from relatively dilute concentrations in air

(from tens to thousands of parts per million by volume) to control emissions. This paper

discusses issues involved in deciding which adsorbent to be used, what type of adsorption

system to be used, and whether it is the right emission control technology. The actual

concentration of the VOC is key to when and how an adsorber would be used.




RISK ASSESSMENT AND MANAGEMENT IN CHEMICAL INDUSTRY

Mr. Nikhil Akhilesh Sinha, Mr.G.S.Zamre



Shri Shivaji College of Engineering & Technology,


Abstract

Risk management is recognized as an essential tool to tackle the inevitable uncertainty

associated with business and projects at all levels. But it frequently fails to meet expectations,

with projects continuing to run late, over budget or underperforming, and business not

gaining the expected benefits.

The goals of chemical safety programs encompass the prevention, assessment, and

management of both short-term and long-term adverse effects to humans and the environment

resulting from the production, use, transport and disposal of chemicals. The tools used

internationally to assess and manage the risks of chemicals on human health have generally

developed independently from the tools used to assess risks to the environment for practical

and historical reasons. However, with increased recognition of the need to protect both

humans and the environment more effectively, an integrated approach to risk assessment that

addresses situations of multi-chemical, multimedia, multicoated, and multispecies exposures

holistically is needed.

Gas Detection Sensor:-

A gas detection sensor permits precise measurement of the concentration of

flammable gas in detection or subject gas the concentration of oxygen in a detection gas

containing flammable gas. In the sensor, the heating of the sensor by contact catalytic

reaction of flammable gas gives off a detection signal of the flammable gas.

This paper explores how to expand risk management to deliver strategic advantage

while retaining its use as a tactical tool in chemical industry and with flammable gas.

Abstract

This paper reviews fundamental issues concerning the crude unit processes. Different

types of corrosion occurring in the different processing vessel, each type of corrosion has

significant control measures. It causes failure of processing vessel and various refinery

equipment dealing with the water and chemicals. Corrosive substances may be liquid or solid,

but most of the liquid which are corrosive include, acids, bases, boiler feed water etc. Various

factors which promote corrosion rate like oxidizing agents, temperature, pH, films, dissolved

salts, fluid velocity, impurities etc. The inorganic salts, sulphur compounds, organic acids,

H2S these are major contributor of corrosion in refinery.

Amines are used in the refineries and gas plant to remove both H2S and CO2 from

feed gas like LPG. CO2 causes problem in hydride formation and affect the specification of

products such as ethylene in gas cracking unit. The corrosion in amine plant is not caused by

amine itself but caused by the H2S, CO2 and by amine degradation products. Control

measures to avoid corrosion in amine plant like selection of material of construction and

operating parameters over which corrosion not occur also have been included in this paper.

Abstract

Reactive distillation technique has become an interesting alternative to some

conventional process especially useful for equilibrium-limited reactions such as esterification

and ester hydrolysis reactions. Conversion can be increased far beyond what is expected by

the equilibrium due to the continuous removal of reaction products from the reactive zone.

This helps to reduce capital and investment costs and may be important for sustainable

development due to a lower consumption of resources.

Reactive distillation is a novel approach to efficient work for homogeneous and

heterogeneous catalyzed esterification of any acid with alcohol in reactive distillation

column. A packed bed reactive distillation column filled with suitable catalyst to perform

esterification reaction is used.

Here we discus how the reactive distillation is useful to perform esterification

reaction, business drivers such as economics environment and social improvements, the scale

up methods applied from pilot plant to commercial scale, advantages of homogeneous and

heterogeneous catalyst.

Abstract

The reaction of molecular bromine (Br2) with aromatic aldehydes and 2-

aminothiophenol is known to produce 2-aminobenzothiazoles. We shown here that

phenyltrimethylammonium tribromide (PhNMe3Br3), a stable, crystalline organic ammonium

tribromide (OATB), can be readily utilized as an alternative electrophilic bromine source. It

is easier to control the stoichiometry of addition with an OATB, which minimizes aromatic

bromination caused by excess reagent. In present work we have developed a novel

application of phenyltrimethylammonium tribromide (PTAB) for the one-pot synthesis of

substituted benzthiazoles from substituted benzaldehydes and 2-aminothiols.

Abstract

A DRUG broadly speaking, is any substance that, when absorbed into the body of a

living organism, alters normal bodily function. In pharmacology, a drug is a CHEMICAL

SUBSTANCE used in the treatment, cure, prevention or diagnosis of disease or used to

otherwise enhance physical or mental well being. Drugs are usually distinguished from

endogenous Bio-chemicals by being introduced from outside the organism. Drugs both

MEDICINAL and RECREATIONL, can be administered in a variety of ways rather than just

one. Drug delivery system generally classified into Primary, Secondary and Tertiary

categories.

Recent studies have led to significant advances in understanding the impact of key

drug carrier properties such as, SIZE, SURFACE CHEMISTRY and SHAPE on their

performance. The successful drug delivery carries to navigate through multiple physiological

hurdles including Reticulo Endothelial System (RES) clearance, target accumulation,

intracellular uptake and endosomal escape. Each of these processes may require unique and

often conflicting design parameters, thus making it difficult to choose a design that addresses

all these known hurdles.

Researchers have attempted for many years to develop drugs based on QSAR

(Quantative Structure Activity Relationships) and simultaneously based on Kernel

Regressions (Algorithms). However, access to computational resources was not available

when these efforts began, so attempts consisted primarily of STATISTICAL

CORRELATIONS of structural descriptors with biological activities. This presentation will

discuss the application of QSAR & KERNAL in drug design. Some examples which will be

presented on computer assisted drug and molecular design and some, on computer-based

Visualization and Modeling.

Abstract

In this work, selected polymeric entrainers have been assess their capability of

breaking the azeotrope of ethanol/water and MTBE/methanol systems. Solubility testing and

group contribution model calculations were used to guide in the initial selection of potential

polymers. Therefore a software package was developed in order to find a suitable solvent

(entrainer) for the above mentioned separation processes. The entrainer selection is based on

azeotropic data, activity coefficients at infinite dilution and vapour-liquid equilibrium (VLE)

data. These data are taken from actual data banks as well as from thermodynamic models.

Experimental VLE measurements were performed to determine whether the selected

polymers are capable of breaking the azeotrope. Selected polymeric entrainers capable of

breaking the azeotrope for the ethanol/water system. Poly(ethylene glycol) at 10 wt % and

poly-(acrylic acid) at 0.45 wt % did break the azeotrope for the ethanol/water system.

Other polymeric entrainers used with the ethanol/water system might be capable of

breaking the azeotrope, but we could not conclusively determine this from the collected data.

In this work we will try to investigate new entrainer and increase purity of product.

Abstract

Coal bed methane (CBM) or coal bed gas is a form of natural gas extracted from coal

beds. In recent decades it has become an important source of energy in United States,

Canada, and other countries. Australia has rich deposits where it is known as coal seam gas.

The primary energy source of natural gas is a substance called methane (CH4). Coal bed

methane (CBM) is simply methane found in coal seams. It is produced by non-traditional

means, and therefore, while it is sold and used the same as traditional natural gas, its

production is very different. CBM is generated either from a biological process as a result of

microbial action or from a thermal process as a result of increasing heat with depth of the

coal. Often a coal seam is saturated with water, with methane is held in the coal by water

pressure[1]. Currently, natural gas from coal beds accounts for approximately 7% of total

natural gas production in the United States.

Abstract

A number of approaches to reducing energy consumption in many important

applications and, thus have direct impact on reducing green house gas emissions. Reducing

friction and improving wear resistance in the motor and the drive is vital in automotive

sector. Reducing friction can lower fuel consumption by about 2% and result in reducing

carbon dioxide emissions. Nano-based nano- coatings and lubricants can significantly reduce

friction coefficient. Reducing energy consumption by using more efficient technologies that

minimize the use of fossil fuels. The adoption of technologies that use renewable energy and

energy storage technologies. Tackling carbon management issues involving separation,

capture, storage and conversion to useful products. Nanotechnology involves consistent use

of nanomaterials such as nanocatalysts, nanomembranes, nanoparticles, aerogels, etc. and

their production requires considerable amount of energy. Batteries and supercapacitors: plug-

in electric and plug-in hybrids have potential to reduce drastically reduce the global warming

and air pollution cause and would also curb our dependence on oil. Nanotechnology holds

great promise for improving performance and life times of Li-ion batteries. It also has the

potential to improve energy and power density, reduces charging time, size and weight

reduction, while improving security stability of the batteries.

University department of chemical technology, NMU


Abstract

The Advanced High-Temperature Reactor (AHTR) is a new reactor concept under

development that uses a solid high-temperature fuel and a liquid fluoride salt coolant.

Depending upon the specific salt coolant that is selected, the liquid melting point of the

coolant is between 350 and 500°C with boiling points typically at or above 1300°C. The very

high volumetric heat capacity of the coolant and its other properties enable the development

of compact modular reactors as well as high-power reactors with passive safety systems. The

base-case design with prismatic fuel blocks is described. The results of a series of trade

studies that may significantly extend AHTR capabilities are also described. Studies of

AHTRs with pebble-bed fuel have developed an AHTR concept with (1) significantly lower

fuel cycle costs than traditional gas-cooled pebble-bed reactors and (2) uranium consumption

per unit of electricity that is 64% of a light-water reactor. Studies of AHTRs with pin-type

fuel assemblies for large power levels have developed core designs with the potential for

significantly better actinide-burning capabilities than either light-water reactors or sodium-

cooled fast reactors. A conceptual beyond-design-basis accident (BDBA) system has been

developed that may allow failures of all decay-heat removal systems (except heat transfer to

the ground) without significant release of radio nuclides to the environment in a large

reactor. This is a significant enhancement in financial risk reduction compared to the present

generation of reactors. The basis for these conclusions and the important technical

uncertainties are described.

IN PROCESS INDUSTRIES Ajay R. Randhe, Pravin A. Koli*

Shree Sant Muktai Institute of Technology (S.M.I.T.), Jalgaon

Abstract

Industrial plants can be thought of as being composed of two distinct systems – the

manufacturing process itself, and the energy supply facilities (often called "Plant Utilities")

required to drive the process. Plant utilities means streams which do not directly interfere the

process but it indirectly affects the efficiency and the quality of the product obtained and

without which plant cannot run. Industrial plant utility systems can be quite complicated.

They usually include between 3 to 5 subsystems, all of which interact with one another to

some degree. These are namely water, steam, air, refrigeration, vacuum, inert gases. There is

an important characteristic of the plant utility systems (PLUS) which is directly related to the

efficiency of the process. Since the plant utility system is required to meet the utility needs of

the process under varying operating conditions (such as startup, shutdown and other

abnormal operations) it is typically designed for considerable operating flexibility. This

flexibility shows up as surplus equipment in the system. The focus of this poster is to

describe how various plant utilities are applied in process plants for use in mitigating the

economic consequences of industrial production.

Email: [email protected];[email protected]

Abstract

In plants, photosynthesis uses solar energy to convert carbon dioxide and water to

sugars and other hydrocarbons. Biofuels are refined from sugars extracted from crops.

However, in artificial photosynthesis, an electrochemical cell uses energy from a solar

collector or a wind turbine to convert to simple carbon fuels such as formic acid or

methanol, which are further refined to make ethanol and other fuels. The key advantage is

that there is no competition with the food supply and it is a lot cheaper to transmit electricity

than it isto ship biomass to a refinery. In this technology ,theelectrochemical cell is used as a

flow reactor, separating the gaseous input and oxygen output from the liquid electrolyte

catalyst with gas-diffusion electrodes. The cell design allows the cell reactor to fine-tune the

composition of the electrolyte stream to improve reaction kinetics, including adding ionic

liquids as a co-catalyst. This technology brings us a significant step closer to reducing our

dependence on fossil fuels while simultaneously reducing emissions that are linked to

unwanted climate change.

concentration in water and wastewater to acceptable levels before its transport and cycling

into the environment. Literature review has established that the synthetic activated carbon has

highest efficiency in removing chromium from waste water amongst the various adsorbents

that have been investigated by the past researchers. In the present work, activated carbon

made out of ground nut husk (which is usually a waste) has been investigated as a natural

adsorbent for the removal of chromium from aqueous solution. Batch experiments were

carried out with a known concentration of chromium in an aqueous solution. Various

parameters such as adsorbent doses, reaction time, temperature, and agitation were

investigated. The study revealed that the carbon made out of groundnut husk acts as very

promising adsorbent as regards to chromium removal. Based on the encouraging results

obtained, we intend to conduct the continuous operation of chromium removal with the aid of

groundnut husk and optimize the parameters involved in the process.

Abstract

As the industry grapples with the concept of sustainable development, risk assessment

represents a potentially useful methodology to engage operations with the broader range of

issues involved. However, a limitation of the traditional risk mitigation approach is that it

focuses on avoiding negative outcomes, whereas a sustainability focus requires consideration

of positive impacts as well. The paper presents a risk assessment approach, which uses

analytic hierarchy process (AHP) to directly and holistically estimate risk, showing greater

flexibility in comparison to traditional methods. It describes the rationale for the project, the

outcomes from the trials and the overall lessons from the exercise This is an essential area to

focus on in order to move beyond the traditional risk mitigation approach towards a more

proactive approach to positive impacts, which can be realised by mining operations. Through

examining organizations with good safety performance, it was intended to identify common

features that are associated with good safety performance. The mining industry‟s contribution

to sustainable development will ultimately be judged not by what is written in policy

documents and public reports, but by what is happening „on the ground‟ at individual

operations. A major challenge for companies, therefore, is to find productive ways of

engaging with sites about sustainable development issues.

Abstract

Increased concerns about environmental damage caused by mineral oil based

lubricants, has created a growing worldwide trend of promoting vegetable oil as base oil for

automobile lubricants. Coconut oil, which is abundantly available in southern states of India,

is reportedly being widely used as two-stroke engine lubricant (2T oil) by autorikshaw1

drivers. A survey among the users of coconut oil as 2T oil brought forth complaints of

increased engine wear. This paper presents tribological properties of coconut oil evaluated

using a four-ball tester and a test rig to test the wear on two stroke engines. The influence of

an antiwear/extreme pressure (AW/EP) additive on the tribological performance of coconut

oil was also evaluated experimentally. The addition of the AW/EP additive has brought about

considerable reduction in wear with coconut oil as 2T oil.

Abstract

Hydrogen sulfide is a highly toxic and corrosive gas which is one of the larger

pollutants of the atmosphere. Cleaning of this gas is necessary not only for pollution

abatement but also for effective use of the gas mixtures like natural gas, biogas etc. for end

use applications like power generation in IC engines, production of heat and steam, electricity

generation/co-generation, use as vehicle fuel: where the presence of hydrogen sulfide at

higher concentration corrodes the internal parts of the engines in a very short operational

duration of run. This various pathways for using biogas show the need of biogas purification,

including the H2S removal.

This paper addresses the removal of hydrogen sulfide from biogas using Fe/NTA

solution. The process consists of two stage countercurrent scrubbing of hydrogen sulfide

from biogas using a chelated polyvalent metal ion which undergoes reduction, followed by

removal of precipitated sulfur in the filtration unit and the oxidation of the reduced metal ion

using oxygen in the air, for recycling.

This particular biogas purification strategy offers many advantages. For instance, the

process can be performed under mild environmental conditions and at low temperature, and it

removes H2S selectively. Because the catalytic Fe/NTA solution is easily regenerated, no

chemicals are consumed. Finally the end product of extraction is elemental sulfur, which is a

stable material that can be easily commercialized or disposed of with minor potential for

further pollution.

ABSTRACT A life cycle assessment (LCA) analysis has been carried out in order to determine the

ecological and carbon footprints associated with biodiesel production from Moringa oleifera

oilseeds. This LCA analysis consists of pre-farm, on-farm and post-farm stages. Pre-farm

data included the information on the production of inputs, on-farm stage included

environmental emissions from diesel use and nitrous oxide (N2O) emissions from N fertiliser

applications and the post-farm stage included dehusking of oilseeds and the conversion of the

production of biodiesel from Moringaoleifera oilseeds.

In this research, global warming and fossil fuel resource scarcity have been found to

be the predominant impacts of the production of biodiesel. Greenhouse gas (GHG) emissions

during the production of 1,000 litres of biodiesel was 1,543 kg of CO2-e (kg CO2 e), when

the biodiesel was produced from Moringa oleifera oilseeds, grown under irrigated conditions.

The GHG emissions under dryland conditions were found to be 33% lower CO2 (i.e. 1,171

kg CO2-e) than that for irrigated conditions for the same level of biodiesel production.

Emissions from the paddock accounted for a significant portion of GHG emissions from

biodiesel production from Moringa oleifera oilseeds, with irrigated land production. Fossil

fuel usage (largely attributed to farm machinery) is a major environmental impact (40%)

from biodiesel production from Moringa oleifera oilseeds under dryland production.

ABSTRACT

Cholesterol is soft waxy fat that is carried through the blood stream. Although

cholesterol is necessary for cell function and body hormones and energy, elevated level

accumlate in blood & lead to health corncern, treatment for lowering cholesteral level often

include anti-cholesterol medication one of which is usally a statin, many drugs, including

some statins are metabolised by enzyme CYP3A4. Howhere, the same enzymes metabolizes

grapefruit juice and combition of some statins casues some high concentration of the drugs

accumlates in the body. Adverse effect such as muscle pain, fatigue & fever or evel fatal

consequences many results. In vitro studies shows that inhibition of CYP3A4 decreased

simvastin metabolism and had no effect on pravastin.

Intraconzole is a drugs used for the treatment of fungal infestation. Howhere, it is

known inhibitor of CYP3A4 and many cause negative side effects if used concomitant with

cholesterol lowering drugs. Other cholesterol lowering drugs such as fenofibrate and niacin,

if used in conjuction with HMG-COA reductase inhibitors, may cause potentally hazardous

drugs interactions.

ABSTRACT:

Sustainable production of renewable energy is being hotly debated globally since it is

increasingly understood that first generation biofuels, primarily produced from food crops

and mostly oil seeds are limited in their ability to achieve targets for biofuel production,

climate changemitigation and economic growth. These concerns have increased the interest in

developing second generation biofuels produced from non-food feedstocks such as

microalgae, which potentially offer greatest opportunities in the longer term. This paper

reviews the current status of microalgae use for biodiesel production, including their

cultivation, harvesting, and processing. The microalgae species most used for biodiesel

production are presented and their main advantages described in comparison with other

available biodiesel feedstocks. The various aspects associated with the design of microalgae

production units are described, giving an overview of the current state of development of

algae cultivation systems (photo-bioreactors and open ponds). Other potential applications

and products from microalgae are also presented such as for biological sequestration of CO2,

wastewater treatment, in human health, as food additive, and for aquaculture.

Abstract Nowadays, waste tires disposal has become a relevant environmental problem.

Although pyrolysis processes seem to be a feasible alternative treatment, a proper application

for generated residues is a task to be solved. In this context, the aim of this work is to valorize

pyrolytic tire char by means of the production of a useful adsorbent for air purification. An

activation process with CO2 was chosen to control the process of microporosity generation.

The activation reaction and the textural properties were followed to achieve the

understanding of porosity evolution. A change in the reaction rate in the first steps of the

process was observed, followed by a linear relationship between activation time and burn off.

Microporosity is generated in two main processes. At the beginning, narrow micro porosity is

formed, and later, a widening of the microspores is taking place. The performance of the new

obtained samples for hot gas cleaning was tested by a process of Phenanthrene (Phe)

adsorption in a fixed bed reactor with a process temperature of 1500c at low inlet

concentrations. It was concluded that the porosity development, both micro-and

nonmicroporosity, increases the physical adsorption capacity of activated carbons, likely due

to a multilayer adsorption process.

Abstract

Among the chief technologies available for reduction of NOx emissions is Selective

Catalytic Reduction (SCR). SCR Technology was initially developed in the United State and

then commercialized in the World including India. A major advantage of SCR is that the

reaction products, nitrogen and water, are innocuous compounds already present in air.

A major environmental issue in the generation of electric power is the emission of

nitrogen oxide, collectively referred to as NOx. NOx consist primarily of nitric oxide (NO)

and lesser amounts of nitrogen dioxide (NO2). The goal of the Clean Coal (Carbon)

Technology Development Programme (CCTDP) Is to enhance the utilization of coal as a

major energy source. Part of this Programme is the demonstration of technologies designed to

reduce emissions of oxides of nitrogen (NOx) from existing coal -fired utility boilers. NOx is

an acid rain precursor and a contributor to the formation of ground-level atmospheric ozone,

which is a health hazard and is also related to smog formation. In 1995, a CCTDP project was

concluded in U.S. that demonstrated SCR technology for the control of NOx emissions.

The SCR processes consists of injecting ammonia (NH3) into boiler flue gas and

passing the flue gas through a catalyst bed where the NOx and NH3 react to form nitrogen

and water-vapor. The results of the CCTDP confirmed the applicability of SCR for coal-fired

power plants. The SCR catalyst made of a solid ceramic material that contains active catalytic

components.

Keywords- SCR, NOx emissions, CCTDP, Coal Fired Utility Boiler.
