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.

• 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.
