This document provides information about humidification and its importance in the cotton industry from a training submitted by Anurag Gupta. It discusses that humidification means water vapor in air and helps maintain the weight and properties of cotton fibers. It defines specific and relative humidity and lists the ideal humidity and temperature levels for different cotton processing departments. The document also outlines the components and processes within a humidification plant, including rotary drum filters, ring frames, and reverse osmosis systems. Finally, it briefly describes different types of air compressors used in humidification plants.

HUMIDIFICATION PLANT & UTILITY
SUBMITTED TO: - SUBMITTED BY:-

(Head of Department) Dept:-Mechanical Engg.
Batch:-2013-2017

2. 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.

3. PHYSICAL PROPERTIES OF COTTON
• HYGROSCOPIC NATURE:- Absorb moisture
from surrounding environment
• ELASTIC PLASTIC NATURE:- Crystalline
polymer system
• Tenacity:- Strength of cotton fibres

4. 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

6. 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.

10. RO SYSTEM
• Reverse Osmosis
• Normally flow high solute concentration to low
solute concentration through a membrane

11. 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

12. RECIPROCATING COMPRESSOR
Pros:
Comparatively cheap
Easy to maintained
Available to high presser
Cons:
Very humming
High outlet temperature
Many moving parts

13. ROTARY CENTRIFUGAL
COMPRESSOR
Pros
Actually very quite
High efficiencies
High presser can achieve
Cons
Relatively high cost
Compressed air is very hot
Complicated monitoring
