COMPRESSION AND COOLING

Cryogenic air separation begins with the ambient air being filtered to remove dust and any other particulates . It then passes through a compressor and is cooled , which condenses and removes much of the water vapor content present .
It then goes through a series of filters – including molecular sieve absorbers – to remove as much of the carbon dioxide ( CO 2 ), hydrocarbons , and moisture ( H 2 O ) as possible .
