Cryogenic Air Separation • Air Feed • Air is drawn into the plant by main air compressor. • Cleaning • The 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.
Cryogenic Air Separation • Compressing • The air is compressed to high (150 psi) pressure for expansion. • Cooling • The 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.
Cryogenic Air Separation • 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.
Cryogenic Air Separation • The pure products are drawn off to: • store in cryogenic storage tank, • deliver to the customers by liquid tanker • or pure products are feed to customer by pipeline network.
