Air is drawn from atmosphere through Suction Air Filter. (1).Air is drawn from atmosphere through Suction Air Filter to prevent dust from getting into the system
The air is then compressed in a three stage Air Compressor (2) with after cooler to a maximum pressure of 55 Kgs./Cm2 for plant starting conditions and a pressure of 40 - 45 Kgs./Cm2 for best results normal running conditions. Depending on ambient conditions and good operations the operating pressure of the Air Separations Unit is brought down to 40 Kg/Cm2 as per past experience. Air Compressor has inter-coolers between stages and an After-Cooler after 3rd stage. For further details on Air Compressor, please refer to Air Compressor Manual supplied by the Air Compressor manufacturer. The air compressor should be maintained properly in good condition as it is the main source of air supply to the plant.
