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.
