Abstract

Compressed air satd. with water e.g. at 30 degrees C, 9 bars, is dehumidified in a combined single shell unit, with a preliminary cooler, to reduce air temp e.g. to 18PC by passage through a transverse horizontal hairpin tube bundle the tubeside cooling water from which is recycled by pumping through the reheater, at the other end of the pref. horizontal shell. Temp is reduced e.g. to 5 degrees C by a second heat exchanger, using refrigerant fluid; and water is removed by upwards passage of air through a filter layer, vertical baffles being used to direct flow. Dry air exits e.g. at 20.7 degrees C, after passing through the reheater, and water is removed from bottom of shell.
