Air Compressor
Filtered air is compressed by a centrifugal compressor in an oil free system.
CoolingWater Supply
Chiller
Provides a further stream of cooling water, chilled by waste gas and nitrogen, for use in the direct cooler.
Molecular Sieve Adsorbers
Removes water and carbon dioxide from the air in dual vessels on alternate duty. Regeneration gas cleans the off-stream vessel.
RegenerationGas Heater
Regeneration Gas Heater
Heats regeneration gas to required temperature.
Air Separation Process Description
CoolingWater
Direct Contact After Cooler
Cools and washes air by direct contact with cooling water.
Air Separation Process Description
Main Heat Exchanger
Main Heat Exchanger
Cools the purified air close to its liquification point against outgoing gaseous oxygen and nitrogen product streams and waste nitrogen. Cooled air passes to the high pressure column and the expansion turbine.
companderCompander
Meets process refrigeration requirements by expanding part of the cold compressed air.
low pressureupper column
high pressurelower column
High and Low Pressure Columns
Initial separation of the air into an enriched oxygen liquid at thesumpof the high pressure column and nitrogen at the top. The low pressure column provides the separation into high purity oxygen , nitrogen product, waste nitrogen, and raw argon feed.
Subcooler
Subcooler
Subcools enriched oxygen liquid and liquid nitrogen to provide column reflux. Liquid nitrogen is also removed downstream of the subcooler as product.

•Crude Argon Column
Separation of the O2/Ar merge extracted from the LP column into a sump product with a low argon content, returned to the LP column and a crude argon at the top.
• Heat Exchanger
The crude argon is heated up in the heat exchanger to ambient temperature.
• DEOXO Process
The oxygen contained in the crude argon is separated in a deoxo by catalytic combustion with hydrogen.
• Water Main Condensor
The water produced is removed partly by condensing and completely by the molecular adsorbers.
• High Purity Argon Column
The oxygen free crude argon is separated into a nitrogen rich residual gas and LAR in the high purity argon column.

Argon Recovery Process DescriptionDirect Rectification
Crude ArgonColumn
99% Ar1% N2
• Crude Argon Column
Raw argon gas from the low pressure column is used as feed gas for the crude argon column.In the crude argon column the oxygen is removed by means of cryogenic rectification.
Argon Condenser
•Argon Condenser
Reflux for the crude argon column is provided by condensing the main part of the O2 free crude argon against the rich liquid from the pressure column in the top condenser.
High PurityArgon Column
• High Purity Argon Column
Part of the oxygen free crude argonis withdrawn subcooled and fed to the pure argon column.Nitrogen in the pure argon column is removed by cryogenic rectification.Liquid argon from the sump is transferred to the liquid storage tank.
