Other Details

Atmospheric air consists mainly of oxygen and nitrogen gas as well as small amounts of water vapor, carbon dioxide, argon, helium, and the like. The oxygen and nitrogen from the air are separated by boiling point difference by distillation through a fractional column. Aspirated by a multi-stage compressor by a filter and is compressed to design pressure. The compressed air is then passed through intercoolers, industrial refrigerator, moisture separators, and then to the molecular sieve battery for removal of carbon dioxide, hydrocarbons and process air humidity . This pure air then passes through the first heat exchanger, where it is cooled by the outgoing nitrogen and oxygen. A part of this cooled air is passed through the expansion motor and the other part through the second heat exchanger. The expansion motor and the second heat exchanger help to cool the air further, which is finally released at the bottom of the column by an expansion valve. The air becomes liquid at this stage.
