Asu Air Separation Plant Oxygen Plant
An air separation plant separates atmospheric air into its primary components,
Typically nitrogen and oxygen, and sometimes also argon and other rare inert
The ASU Plant produce Liquid Gas as the following Seven Steps:
1 Before compression the air is pre-filtered of dust.
2 Air is compressed where the final delivery pressure is determined by recoveries and the
Fluid state (gas or liquid) of the products. Typical pressures range between 5 and 10 bar gauge.
The air stream may also be compressed to different pressures to enhance the efficiency of the
ASU. During compression water is condensed out in inter-stage coolers.
3 The process air is generally passed through a molecular sieve bed, which removes any
Remaining water vapour, as well as carbon dioxide, which would freeze and plug the cryogenic
Equipment. Molecular sieves are often designed to remove any gaseous hydrocarbons from
The air, since these can be a problem in the subsequent air distillation that could lead to
Explosions. The molecular sieves bed must be regenerated. This is done by installing multiple
Units operating in alternating mode and using the dry coproduced waste gas to desorb the water.
4 Process air is passed through an integrated heat exchanger (usually a plate fin heat exchanger)
And cooled against product (and waste) cryogenic streams. Part of the air liquefies to form a
Liquid that is enriched in oxygen. The remaining gas is richer in nitrogen and is distilled to
Almost pure nitrogen (typically < 1ppm) in a high pressure (HP) distillation column. The
Condenser of this column requires refrigeration which is obtained from expanding the more
Oxygen rich stream further across a valve or through an Expander, (a reverse compressor).
5 Alternatively the condenser may be cooled by interchanging heat with a re boiler in a low
Pressure (LP) distillation column (operating at 1.21.3 bar abs. ) when the ASU is producing
Pure oxygen. To minimize the compression cost the combined condenser/reboiler of the
HP/LP columns must operate with a temperature difference of only 1-2 degrees Kelvin, requiring plate fin brazed aluminum heat exchangers. Typical oxygen
Purities range in from 97.5% to 99.5% and influences the maximum recovery of oxygen.
The refrigeration required for producing liquid products is obtained using the JT effect in an
Expander which feeds compressed air directly to the low pressure column. Hence, a certain
Part of the air is not to be separated and must leave the low pressure column as a waste stream
From its upper section.
6 Because the boiling point of argon (87.3 K at standard conditions) lies between that
Of oxygen (90.2 K) and nitrogen (77.4 K), argon builds up in the lower section of the low
Pressure column. When argon is produced, a vapor side draw is taken from the low pressure
Column where the argon concentration is highest. It is sent to another column rectifying the
Argon to the desired purity from which liquid is returned to the same location in the LP column.
Use of modern structured packings which have very low pressure drops enable argon purities
Of less than 1 ppm. Though argon is present in less to 1% of the incoming, the air argon column
Requires a significant amount of energy due to the high reflux ratio required (about 30) in the
Argon column. Cooling of the argon column can be supplied from cold expanded rich liquid or
By liquid nitrogen.
7 Finally the products produced in gas form are warmed against the incoming air to ambient
Temperatures. This requires a carefully crafted heat integration that must allow for robustness
Against disturbances (due to switch over of the molecular sieve beds). It may also require
Additional external refrigeration during start-up.
