6 Cryogenic Air Separation Air FeedAir is drawn into the plant by main air compressor.CleaningThe air goes through a filter house to remove dust and large particles.The air is then cooled and cleaned of CO2 and moisture by passing it through a molecular sieve drier.
7 Cryogenic Air Separation CompressingThe air is compressed to high (150 psi) pressure for expansion.CoolingThe cool and dry air is then cooled even further to -300°F (-185°C) in the main heat exchangers and is then sent to the distillation column.
8 Cryogenic Air Separation The air is separated into its elemental components in the form of liquid oxygen, argon and nitrogen, based on its different boiling points.The more volatile components, nitrogen, will rise up and oxygen will go down while argon will be somewhere in between.
9 Cryogenic Air Separation The pure products are drawn off to:store in cryogenic storage tank,deliver to the customers by liquid tankeror pure products are feed to customer by pipeline network.
