ABSTRACT:
In the compression of gases with interstage cooling in low pressure drop towers in which evaporative and non-evaporative cooling liquids are used to cool the compressed gases, the present improvement comprises introducing the non-evaporative cooling liquid as a stream in a direct contact zone and introducing the evaporative cooling liquid as a separate stream in a direct contact zone thereabove and removing evaporative cooling liquid between said zones so as to prevent it from mixing with the non-evaporative cooling liquid stream.
