CHAPTER 1
INTRODUCTION
A. INTRODUCTION ABOUT THE UGAR SUGAR WORKS 1. Background 1.1 The Ugar Sugar Works Ltd. is one of the pioneers in sugar production in the
state of Karnataka; the Company was incorporated on 11th September 1939,
under the able guidance and kind patronage of his late highness The
Rajasahab of Sangli with a crushing capacity of 500 tons per day.
1.2 Vaidya and Company was the first Managing Agents. In the year 1940, M/s.
Shirgaokar Brothers were called to manage the affairs of the Company and
they were the Managing Agents till 31st December 1969. M/s. Shirgaokar
Brothers who had by then made the Kolhapur Sugar Mills outstanding and
notable success proved to be successful in bringing up the Ugar Sugar
Works Ltd., also.
1.3 Under the overall supervision and control of M/s. Shirgaokar Brothers the
crushing capacity of the factory has been increased from time to time as
detailed in Table No. 1.1. At present the cane crushing capacity 12,000 TCD.

1.4 The company has introduced number of irrigation schemes for the
UCL
11
development of sugarcane in the area.
1.5 The company has started its own distillery during the year 1962-63 and liquor
section in the year 1967-68. New distillery plant unit with production capacity
of 45000 liters of rectified spirit has been commissioned in March 1995.
2. Cane availability 2.1 In Belgaum District where the plant is located, sugar cane is available from
the month of October to April even many times the season has to extend up
to the end of May. Typically, sugar cane availability is for a period of 7 to 8
months in a year. The registered area under sugar cane cultivation allocated
to Ugar Sugar Company is 60,000 acres. The important factor with regard to
the operation of USWL is that the cane arrival is fairly uniform and the plant
reaches the maximum crushing rate within a month of season
commencement. The total cane availability during a season is approximately
40 Lakh tones and most of it reaches the plant during the crushing season.
But now, due to new sugar plants installed in the nearby area, crushing
season days have reduced from 8 months to 5 to 6 months.
3. Steam Generation System
3.1 The main source of energy for the plant is bagasse and on an average the
bagasse generated is about 29% of the cane crushed. About 1 % of the
bagasse generated is utilized for juice filtration and the balance is available
for steam generation. While operating on a steady load the savings achieved
by the plant is about 2 to 3% on cane.
3.2 At present, the sugar plant supplies the entire steam requirement of the
distillery, which is around 10 to 15 tons per hour.
3.3 The existing steam generation system consists of 4 high pressure & 1 low
pressure water tube boilers and the details of these boilers are as given in
Table 1.2.
3.4 About 90% of the sugar plant's process steam requirement, which is at 2.5 kg
UCL
12
per cm2 abs., is met through exhaust of the backpressure turbines and the
balance requirement, which is at 9 kg per cm2, is met through extraction from
turbine.

4. Power Generation System 4.1 From the above steam, total power is generated through three turbines,
which meets the in-house requirement as well as exportable power to
KPTCL grid. The rating of which are as given in Table 1.3 and 4th Turbine
will be idle during season as it is condensing turbine.

* Siemens Turbine is old and fully condensing type which is modified to take extraction from HP to LP loop, hence it needs minimum 30 TPH steam in condensing.
4.2 During the crushing season for the present capacity all the 3 turbines and 4
Boilers are in operation.
4.3 The average own power generation is about 120.00 million units per year.
The major electrical load of the plant comprises boiler fans, feed pumps,
UCL
13
DC drives, cane cutter motors, centrifugals, injection water pumps and
cooling water pumps.
4.4 In addition to steam turbine generators, there are four diesel generators
available with USWL and the total capacity of the DG sets is 4600 KVA.
These DG sets are utilized as standby source of power during emergency
requirement and during start up operation as well as off-season operation.
5. Water and Condensate System
5.1 Only Exhaust steam condensate is recovered from the major process
equipment like Kestners and evaporators. The water from the above
recovery is utilized as feed water for the boilers. In addition, DM water is
available for feed water make up requirement.
6. Major Process Equipments
6.1 The plant follows standard three and half-massecute system for sugar
production.
6.2 The unit has got 2 milling tandems. The WIL mill having a size of 33" x 66"
is capable of crushing 4500 TCD and a second mill namely Shantaram
Machineries Pvt Ltd. having a size of 42" x 84" is capable of crushing 6500
TCD. The milling tandem along with the fibrizer is driven by DC drives.
6.3 The juice evaporation system comprises a quadruple effect evaporation
system. Earlier there was double effect semikesteners followed by
quadruple effect. In all, there were three numbers of SK1 bodies and two
numbers of SK2 bodies + 1 No. Robert’s Body in the pre-evaporators. The
quadruple effect evaporation system has three trains namely A, B & C and
two trains will be always on line. During last modification the above system
has been converted and made straight quad system.
6.4 The quadruple effect evaporation system has three trains namely A, B & C
and two trains will be always on line. The disposition of the heat transfer
surfaces for the streams is as given in Table 1.4

6.8 There are eight cell induced draught cooling towers for removing the heat
absorbed by the re-circulating water from the process.
7. Water supply system 7.1 The complete raw water requirement of the plant is drawn from river
Krishna, which is very near from the plant. The pumping station has got six
pumps out of which two pumps are utilized for sugar plant operation and the
pump ratings are as under:
Pump 1: Capacity: 390 M3/Hour. Head: 36.6 meters.
Pump 2: Capacity: 170 M3/Hour Head: 36.6 meters.
7.2 The raw water, from the river is brought to the plant by a 600-mm
underground RCC pipe and finally discharged into a constant level water
pond.
8. Boiler Feed Water System. 8.

The raw water is passed through the pre-water treatment plant comprises
solid contact clarifier and chemical dosing system. This clarified water is
passed through DM plants having the capacities of 30m3/hr, 60 and 72
m3/hr. (3 bed de-ionization plants). Exhaust condensate received from the
process and turbine condenser is used directly as Boiler feed water.
Softener water is being used as makeup water for power plant cooling tower
and drainage of this water is used as makeup water for sugar plant cooling
tower.
9. DISTILLERY 9.1 There are two distilleries available with the USWL. One is of very old with
the capacity of 30 KLPD and another one is of 45 KLPD. Total existing
capacity is 75 KLPD. Usw is having IML section also wherein bottling with
their own brand are being manufactured. There is a separate effluent
treatment plant ie evaporation and drying effluent to form a powder is
available with USW.

CHAPTER 2
NEED FOR THE PROJECT 1.0
1.1 All the nearby plants are going for the expansion and the forecast is total
crushing days will be reduced. Previously it was only one sugar factory in
Athani taluka, now there are 6 – 7 sugar factories in the radius of 20 to 30
KM. 1.2 Athani Farmers is going for expansion to 5000 TCD
Krishna SSK is going for expansion to 5000 TCD
Renuka Sugar – Kokatnur is going for expansion to 15000 TCD
Renuka Sugar Raibag SSK is going for expansion to 5000 TCD
Mohanrao Shinde Arag is 2500 TCD.
New plant Shirguppi sugar is coming up with capacity – 5000 TCD
New plant Shivshakti sugar is coming up with capacity 2500 TCD. 1.3 To achieve maximum crushing in minimum crop days with maximum sugar
recovery it is essential to go for expansion. Present overheads at Ugar are
already high, which leads to face difficulties in arriving at competitive cane
price. Hence Ugar Sugar management is proposing to expand the sugar
plant capacity to 20000 TCD.
2 Ugar Sugar has already taken steps to overcome the bottlenecks faced to
crush 416.66 TCH (10000 TCD in 24 hrs) and during last season USWL
has crushed almost 416.66 TCH. One of the bottlenecks is still exists i.e.at
cane unloading station of 42 x 84 mill. Due to space constraint and lower
capacity cane un-loaders they are unable to maintain uniform cane feeding.
Bagasse moisture will be on higher side, which leads to fluctuations in boiler
steam working parameters and in turn affects the crushing. Along with cane
unloading station the other parameters, i.e. reduction in crop days in future,
higher overheads per ton of cane and competitive cane price, sugar plant
expansion seems to be essential. Hence USWL proposing to expand the
crushing capacity.
UCL
18
2.1 Alongwith the expansion of the sugar plant capacity to 20000 TCD it is also
proposed to expand cogen power plant capacity to 76 MW with distillery of
200 KLPD capacity.
2.2 The main areas covered under the sugar plant expansion is mill and Boiling
house..
2.3 Mill Expansion: it is proposed to reshuffle the cane unloading system and
enhancing the unloader capacity from 7.5 MT to 12.5 MT to overcome the
existing cane feeding bottle necks and addition of Zero Mill of size 50” X
100” and last mill of 50 X 100 with GRPF for existing 42 X 84 mill to crush
at the required capacity.
2.4 Boiling House capacity to be increased to 20000 TCD, for new additions
capacity shall be suitable for 909 TCH. One parallel boiling house set has
been proposed for the expansion. 2.5 The viability of the sugar factory is improved due to cogeneration, which is
also a need of the State to have more power to meet the growing power
demand in the State. 2.6 Alcohol plays one of the important role in the countries economy. Alcohol is
by product of sugar industry, which is linked to agriculture. There alcohol
produced from molasses deserves the preferential place as a substitute
feed stock for chemical industry and to bridge a gap in our every need. The
gap between the availability of alcohol and requirement by the industry has
been avoiding.

CHAPTER 3
PRODUCT SALE POLICY 1.0 Sugar Sale Policy
A) Sugar sales are governed by sugar control order of Central Government
& the releases are given to the Sugar Factory in proportion to their
production / stock of season with the factory. Factory will follow these
rules for sugar sale & abide by the rules. Sugar is sold to Government
nominees & or wholesale dealers registered with the Government.
2.0 Molasses Sale Policy A) Molasses sales are governed by State Excise. Factory will possess M1
license issued by the Commissioner of State Excise, which will permit to
produce the molasses, hold in stock & sell molasses to authorized
parties. Factory will find the parties i.e. Distilleries, Cattle Feed producer
or otherwise exporter of molasses who can purchase the molasses at
remunerative price. This will be followed till such time as own distillery
is established.
3.0 Filter Cake Sale Policy (Press Mud) A) Filter cake is produced as a by-product at the rotary vacuum filter where
the muddy juice is filtered. This filter cake is rich in minerals, potash as
also the phosphate, sulphites & organic matter which means rich
manure. Hence, this is most suitable for soils. The factory will adopt the
policy to return the rich manure to soil by selling the filter cake
particularly to cane growers who have supplied the cane to factory. It is
general experience that cane growers are very much interested to
purchase filter cake at a nominal price fixed by the factory.

CHAPTER 4
TECHNO COMMERCIAL ASPECTS
1 Description of operating Scheme: a) The plant operating scheme envisages both mill tandems of Dia 33” X
66” and 42” X 84” will operate at 6000 & 14000 TCD respectively to
the total capacity of 20000 TCD. Boiling house is also being expanded
to take additional load of expanded capacity.
b) 33’’X 66’’ mill with minor modifications will crush 6000 TCD as per the
existing past data. It is proposed to modify and enhance the capacity
of 42 X 84 Mill to 14000 TCD by adding zero mill of 50’’ X 100’’ and
last mill also 50” X 100” along-with the modifications in the cane
unloaders, cane preparatory devices and existing mills.
c) Juice heaters will be added to balance the mass and temperature i.e.
wide gap plate type heat exchanger is proposed to operate on vapour
condensate. Existing juice heaters will be modified to suit the
expanded capacity.
d) Juice sulphiter and syrup sulphiter are proposed to be added suitably
to handle the total juice flow for the expanded capacity
e) It is proposed to add juice clarifier to maintain the required retention
time for juice clarification.
f) Plate type juice heaters are also proposed in addition to the existing to
operate on 1st body vapours
g) It is proposed to add evaporator body for 1st and 2nd effect in the
existing set up, for Heat & mass balance. There will be total 3 streams,
two operating and one set will be cleaning so that every 10 to 15 days
clean set will be online.
h) In addition to the existing Batch type A pans and continuous pan it is
proposed to add one more continuous pan for A massecuite boiling. It
is proposed to add continuous horizontal pans for B and C massecuite
handling.
UCL
23
2 nos batch type A centrifugal machines are prposed for the expanded
capacity
Four numbers of continuous centrifugal machines are proposed for B
and C massecuite for the expanded capacity
Modification is proposed in the sugar drying and sugar hoppers. There
is no change in sugar silo system
One additional sugar bagging and conveying system up to sugar go-
down is proposed
One additional cooling tower is proposed to take additional heat load
generated by condensers
For cogeneration 1 new Boiler of 100 TPH with working parameters of
110 ata and 540 deg C temperature. Alongwith new Boiler one old
Boiler of 32 bar 380 deg temp is proposed modify to get outlet
temperature 490 deg C.
For above Boiler Two TG sets have been proposed, 1 no 12 MW back
pressure TG set suitable for 32 bar steam and one 20 MW double
extraction cum condensing TG set suitable for new Boiler steam.
Switch yard with transmission line is also to be expanded suitably.
Existing Distillery capacity is 75 KLPD, additional 125 KLPD distillery
to be added.
b) Bagasse saving for 135 days operation with 909 TCH increased
crushing & 90 PLF nearly 137696 MT of bagasse can be saved. Total
Bagasse saving in a season for 909 TCH will be about 137696 MT
c) During season as well as off season USW needs steam to distillery 25
TPH and for evaporator drier of ETP about 25 TPH. This requirement
will be fulfilled by operating cogeneration during season & off season.
d) When cogeneration is in operation distillery steam requirement can be
met through the turbine extraction. Hence it is essential to operate
cogeneration during off season with saved bagasse.
e) Accordingly during off season one of the Boilers will be operated on
saved bagasse for maximum possible days.
UCL
24
2 Operation of the Plant During Crushing Season: a) 310 TPH Steam will be generated from 4 nos Boiler at 62 bar and 55
TPH from modified Boiler at 32 bar, 490 deg C temperature, 100 TPH
steam will be generated from new Boiler of 100 TPH capacity.
The entire steam generated in the boiler is fed to four turbines. 260
TPH for SNM Turbine, 92.50 TPH for DEC Turbine and 80 TPH to
new Back pressure Turbine. The uncontrolled extraction from the
turbine at 9 ata gives 37.5 TPH of steam approximately at a
temperature of 270 Deg. C. The controlled extraction from the turbine
at 2.5 ata provides 380.06 TPH of steam approximately at 140 Deg. C.
b) A quantity of 30 TPH of steam, being the difference between the
generation and input to SNM Turbines at 62 bar will be mixed with 32
bar 50 TPH steam from modified Boiler through PRV to get 80 TPH.
c) With the above given steam input & extractions from the turbine, the
co gen TG generates 72890 KW, at the generator terminals. Part of
the generated power is used for meeting power requirement of the
auxiliaries of the co gen plant & the power requirement of the sugar
factory.
d) Only the exhaust steam condensate from the sugar factory process &
the condensate from turbine surface condenser are being used as the
feed water for the boilers. The cycle make up water for the operation
of co gen plant will be DM water.

During production of sugar, valuable by- products like Molasses, Bagasse and press mud are produced. At present all molasses produced is sold to the parties getting allotments of molasses from this factory. The commissioner of excise controlling authority for molasses distribution. The molasses production of this factory is round 60000 Tons per annum, because increased availability of sugar cane and the capacity of the factory to crush all the available molasses. The factory approached Government of Karnataka for grant of license to establish a Distillery suitable capacity. Now the Government of Karnataka has granted for state excise 200 KLPD capacity Distillery. In order to run the distillery through the year, the factory shall get an allotment of about 96000 to 1,20,000 Tones of Molasses is available from their own sugar plant. Balance requirement of about 100000 MT of molasses has to be procured from the market. If therefore the Distillery shall have a daily capacity 200000 liters of Rectified spirit by adopting proven technology of continuous fermentation the factory can have higher productivity. In order to operate the distillery throughout the year say about 300 days/ annum, it is proposed that the Distillery shall have separate boiler in off season of suitable capacity with T.G. set. They shall have its own arrangement for steam & electricity. The Power generated will full for operating the distillery as well as for lightening the roads & buildings. Distillery will discharge spent wash effluent at the rate of 10 to 12 liters per liter of Alcohol produced. Daily production of spent wash shall be 2000 m3 to 2400 m3. The spent wash has high B.O.D. to the extent of 80,000 to 90,000 mg/l. As per the standard laid down by the Government the BOD should be brought down to 100 to 30 mg /l. Before it is charged over land or water respectively. There is no suitable and economical method to achieve these standards. The method of concentration and drying of spent wash besides being very costly, pose number of problems, as regards it maintenance and repairs due to high temperature and corrosive nature of spent wash. The alcohol produced in the distillery shall be sold as per the Government’s directives to the parties getting allotment. The distillery shall make good profits, besides getting better price for its molasses. It provides good opportunity for the further diversification. The distillery project is very attractive as the demand for alcohol will be increasing for manufacturing chemicals. During distillation of Rectified Spirit by product known as fusel oil is produced to the extent of 0.2 to 0.3 per cent of the total alcohol produced. Fusel oil is a mixture of higher alcohol such as propyl alcohol, butyl alcohol and amyl alcohol. Amyl alcohol content ranges from 50 to 60 per cent in fusel oil. Spent wash discharged from distillation column is a valuable by-product if it is used properly. If neglected, it becomes hazardous causing pollution of environment. It is rich in nutrients, for use in fertilizers. It is also capable of generating energy. In anaerobic digestion of spent wash, methane gas is
UCL
38
produced which can be used as a fuel in boiler. The quantity of gas produced is almost sufficient to generate the steam required for generation. It requires secondary treatment for the Distilleries are as under:
1. Rectified Spirit Grade 1 2. Impure Spirit Grade 2 3. Fusel Oil 4. Methane Gas 5. CO2 6. Yeast sludge 7. Ethanol 98.6 8. E.N.A.( Extra neutral alcohol)

CHAPTER 6
LOCATION & SITE ASSOCIATED DETAILS
1) Location of Site & Features:
a) The proposed modification is for 42 x 84 milling tandom and boiling
house. This complex presently consists of the sugar plant with the
crushing capacity of 10000 TCD, co-gen plant of 44 MW capacity and
distillery of 75 KLPD. The plant is located at Ugar Khurd Tq Athani, Dist
Belgaum of Karnataka state. It is 10 km away from Maharashtra border.
The nearest Railway Station is Ugar Khurd & is about 2 KM from the
sugar factory.
b) The following specific features of the site have been discussed in this
section of the report.
i) Availability of adequate space for locating the zero mill, cane
unloader and space for the construction activities.
ii) Suitability of the site for installation of boiling house equipments
such as juice heaters (PHE) juice clarifier, evaporators, pans,
crystallizers, centrifugal machines and sugar grader.
iii) Availability of adequate space for locating the New Boiler and new
Turbine.
iv) Availability of adequate space for locating the Distillery unit and
effluent treatment plant.
v) Availability of road connections for material movements.
vi) Ecological impact.
2) Land Availability: a) The layout of the sugar complex is studied in detail & land required for
addition of zero mill is available between fibrizer and first mill. Last mill
addition is replacement of 42 X 84 mill. There is no need of any
additional space for modifications to be carried out in the milling section.
b) Area required for Clarifier is near existing clarifier on north side.
UCL
58
c) Evaporator to be located towards north side of existing evaporator
bodies.
d) Pan C to be located on west side of the existing C pan.
e) Pan B shall be located on south side of the existing Pan B.
f) Two Centrifugal machines to be located in the series of existing battery
and two machines near melter on east side of the battery.
g) Sugar grader to be located adjacent to the existing grader.
h) Boiler to be located near 50 TPH Boiler south side of the WIL boiler
i) Turbine to be located adjacent to the existing turbine
j) Distillery unit to be located adjacent to the existing distillery
k) Effluent treatment plant to be located in the existing ETP area, adequate
space is available.
3) Inter Connection Aspects: The area identified for the expansion is inside the existing sugar complex.
Hence there will be little obstruction for the material shifting. But it can be
managed.
4) The nearest railway station Ugar khurd 2 KM from the sugar factory. The
state highway connecting sankeshwar to Bijapur is near to the sugar factory.
National Highway No 4 is 70 KM from the factory site. The plant is therefore
well connected by road facilities for the transportation of equipments.
5) Water Availability: The raw water for the sugar plant is required for meeting the following
requirements.
a) Make up water to the steam generator.
b) Make up water to the cooling tower.
c) Ash disposal
d) Other plant services
The estimated additional quantity of raw water requirement for the expanded
capacity given in the enclosed sheet. The sugar plant presently draws water
from River Krishna which has adequate water flow. It is therefore envisaged
that the sugar plant water requirement will be met from the same facility.
6) Availability of Fuel:
UCL
59
a) The project is based on the in house generation of bagasse from the
sugar factory. Plenty of bagasse will be surplus after meeting own
requirement during season.
c) Surplus Bagasse will be stored in the available area. And same can be
used during off season for co-generation.
7) Interconnection with Grid: Grid interconnection facility is already available with the factory, expansion of
the unit can be accommodated adjacent to the site.
8) Ecological Impact: a) All the necessary measures are planned to be taken in the plant design
for minimizing the impact on the ecology of the environment. All those
equipment required for ensuring a safe atmosphere will be provided for
the project & located within the sugar complex premises.
d) The detrimental effect of SO2 & Nos will be partially mitigated by a
green belt along the boundary of the plant generally in line with
Karnataka State Pollution Control Board requirement. The plantation
will also help in oxygen replenishment.
c) The particulate emission from the co-gen plant shall be controlled to
less than 150 mg/Nm3 by the use of high efficiency ESP/ wet scrubber.
d) There will be little thermal pollution of water as a closed cycle concept
has been proposed for the sugar plant. The condenser will be designed
with temperature rise limited to 10 Deg. C. above cooling water entering
the condenser. The hot water will be cooled through induced draft
cooling tower & cooling tower blow down will be discharged into the
nearest drain.
UCL
60
e) There will, however, be some contribution to thermal pollution of the
atmosphere by the discharge of hot flue gases. The effect at ground
level will be minimal, as the heat will be dissipated into higher layers of
the atmosphere.
f) Liquid wastes from the milling plant and boiling house, This water will
be diluted and discharged into circulating water pit after checking for
dissolved solids and pit.
UCL
61
CHAPTER 7 RISK ANALYSIS & MANAGEMENT
1) USWL Performance:
a) Risk of Performance for next 15 years. i) The Ugar Sugar Works Ltd., has achieved excellent performance,
Hence there is no risk of performance
b) Management Stability / Political Environment i) The management of the USWL has been steady in the past. It has
been working as one united team.
ii) USWL has a vast pool of technically qualified staff, which has
gained ample training & experience. Steady management control
mitigates the risks of management instability.
iii) State support for the sugar industry as a whole mitigates the risk of
unfavorable political environment.
2) Cane Availability Risk: a) Availability of water for cane production
i) The risk of non-availability of water for cane production is mitigated,
as sufficient amount of water is available from River Krishna as well
as irrigation on wells & also Lift Irrigation Schemes (LIS) by sugar
factory as well as irrigation pumps of individual cultivators.
UCL
62
iii) Average Rainfall is 600 mm from June to September. The river
Krishna is flowing at 1 km distance from factory. As a result of
availability of water from River, tank & borewell the sugarcane
production is expected to increase.
iv) Risk regarding effects of deregulation & exposure to international
market is mitigated as the sugar factory has already started cutting
costs to remain price competitive by increasing the crushing
capacity & optimizing capacity utilization.
b) Cane Development in the area
i) Significant potential exists for cane development in the area.
ii) Area of operation consists large no. of villages from athani, taluka,
on river bank Krishna. At present cane area is covered by river
irrigation & as well as well irrigation.
iii) Well irrigation area is also benefited by percolation of irrigation
tanks. The cane area is also expected to increase due to addition
of new irrigation schemes.
iv) In addition, the sugar factory has a separate agricultural department
headed by qualified Cane Manager (CM). The agricultural
department takes complete responsibility of the command area for
development of cane.
c) Risks of farmers shifting to cash crops other than cane
i) Farmers are not likely to shift to other cash crops as the sugar
factory offers an assured market for cane & take complete
responsibility of command area whereas other cash crops are
market driven & there is no assured take off.
UCL
63
ii) The relative profitability per hectare of different crops in India as per
the draft report of World Bank is the highest for sugar cane.
3) Fuel Risk: a) Risk of non-availability of bagasse will not arise as bagasse generated
from the own mill will be more than sufficient.
4) Technology Risk: Technology adopted for the expansion plant is an established technology & in
operation in the same plant for the past 75 years.
5) Construction Time: i) Total expansion work requires hardly 6 to 7 months. Hence there is no
risk of work completion before start of the coming crushing season.
6) Environment Risks: i) The compliance with the Indian environmental standards will be ensured
from the time of project design. It is proposed that factory will undertake
