MAJOR TRAINING FROM SAGAR MANUFACTURERS PVT. LTD. ON:-
HUMIDIFICATION PLANT & UTILITY
SUBMITTED TO: - SUBMITTED BY:- KSHITIJ YUGBODH ANURAG GUPTA (Head of Department) Dept:-Mechanical Engg. Batch:-2013-2017
What is humidification and why it plays key role in cotton industry?
• Humidification simply means water vapour present in the air.
• Cotton having hygroscopic property.
• Humidification region has directly impact on the weight of the textile.
PHYSICAL PROPERTIES OF COTTON
• HYGROSCOPIC NATURE:- Absorb moisture from surrounding environment
• ELASTIC PLASTIC NATURE:- Crystalline polymer system
• Tenacity:- Strength of cotton fibres
TYPES OF HUMIDITY
• SPECIFIC HUMIDITY SH=mH2O÷mnet
• RELATIVE HUMIDITY
RH=PH2O÷P*H2O
Example: - A sample of air at 10 degree centigrade can hold less moisture than the same sample of air at 20 degree centigrade.

RELATIVE HUMIDITIES AND TEMPERATURES FOR SMPL
TEMPERATURES FOR HUMIDIFICATION PLANT
• DRY BULB TEMPERATURE(Tdb)
• WET BULB TEMPERATURE(Twb)
• DEW POINT TEMPERATURE(Tdp)i. If dew point temperature is closer to the dry air temperature-the
relative humidity is high.ii. If dew point temperature is well below the dry air temperature-
the relative humidity is low.

RO SYSTEM• Reverse Osmosis • Normally flow high solute concentration to
low solute concentration through a membrane
TYPES OF AIR COMPRESSORS
SCREW COMPRESSOR
Pros: Noise restrictions Low maintenance cost Few moving parts
Cons : Short life Chance of air leakage Limited presser developed
RECIPROCATING COMPRESSOR
Pros:Comparatively cheap
Easy to maintained
Available to high presser
Cons: Very humming
High outlet temperature
Many moving parts
ROTARY CENTRIFUGAL COMPRESSOR
Pros Actually very quite High efficiencies High presser can achieve
Cons Relatively high cost Compressed air is very hot Complicated monitoring
