Compressed Air Production
Compressed air as the second source of industrial energy after electricity, requires a close understanding of the characteristics of compressed air to optimize its production and use.
Optimizing productivity while reducing operating costs is the common goal shared by nearly every manufacturing plant. Compressed air is considered the phantom utility, it cannot be bought, you must produce it. The initial capital cost of a compressed air system is minor compared to the operational cost. A Transair® aluminium and stainless steel pipe system will significantly reduce your operational cost! Transair® can help make your goals of reduced electrical costs a reality.
The pie chart above illustrates the typical cost breakdown for an average compressed air system (compressor, pipe system and operating costs) over a 10-year period.
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 production of compressed air includes necessary elements of compressed air treatment.
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 vapour 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.|
