Abstract

Air is supplied to an air separation apparatus via a heat exchanger in which the entering air is cooled against an air gas separated in the separation apparatus. The air is first compressed in an adiabatic compressor. The air gas separated in the separation apparatus is humidified after it leaves the separation apparatus but before it reaches the heat exchanger.
