Atmospheric Air is sucked in by a multi stage Compressor through a filter and is compressed to the design pressure, The compressed Air is then passed through inter-coolers, Industrial Refrigerator, Moisture Separators, and then to the Molecular Sieve Battery for removal of Carbon Dioxide, Hydrocarbons and Moisture from the process Air. This pure Air then passes through the 1st Heat Exchanger, where it is cooled by the out going Nitrogen and Oxygen. Part of this cooled Air is passed through Expansion Engine and the other part through the 2nd Heat Exchanger. Both the Expansion Engine and 2nd Heat Exchanger help in further cooling down the Air, which is finally released to the bottom of the column through an expansion valve. The Air becomes liquid at this stage.
