Compressed air treatment, compressed air production
Compressed air can be produced by two processes:
- Dynamic compression (conversion of the air velocity into pressure): radial and axial compressors.
- Displacement compression (reduction of the air volume): reciprocating compressors (piston type) and rotary compressors ( screw- , vane-, roots- or liquid ring compressors).
The Air Receiver
The air receiver enables: storage of compressed air in order to meet heavy demands in excess of the capacity of the compressor. balancing of pulsations from the compressor. cooling of the compressed air and collection of residual condensate.
The Air Dryer
The air dryer reduces the water vapor content of compressed air. Moisture can cause equipment malfunction, product spoilage and corrosion. Two methods are used : absorption and refrigeration.
Filters restrict the passage of oil and water particles conveyed by compressed air within the system.
Drains eliminate condensate (condensate water mixed with other impurities generated by compressed air and sources of pollution).
The separator receives condensate from the drains. It separates oil and water avoiding any polluting discharge.
