PSA Oxygen Gas Plants

Share |

Pressure swing adsorption oxygen gas plants and oxygen generating system unit plants are suitable for a large number of industrial applications. Oxygen is an important ingredient that is required in large volume in many applications. PSA method which is described here is most productive for relatively smaller applications. The unique feature of PSA Oxygen Gas plants is that apart from being environment friendly, they have the ability to remove gases like Carbon dioxide from waste gas streams.

The principle of adsorptive separation of air is done by the following process:

Compression of feed air and conditioning: The ambient air gets compressed by an air compressor, then dried by an air dryer and subsequently filtered before entering the process vessels.

Adsorption: Pre-treated air is allowed to pass into a vessel filled with Zeolite Molecular Sieve (ZMS). Here most of the oxygen pass through while nitrogen and other gases gets adsorbed. The adsorption process is interrupted before the adsorption capacity of the ZMS is fully exhausted.

Desorption: The saturated Zeolite Molecular sieve is regenerated by way of of pressure reduction. This is below that of the adsorption step. It is done by a simple pressure release system. The waste stream that was got is vented into atmosphere. While regenerated adsorbent is purged with oxygen and used again for the generation of oxygen.

Oxygen receiver: The alternate steps of Adsorption and desorption takeplace at equal time intervals. This in effect means that the continuous generation of oxygen can be achieved with these two adsorbers, while one is being switched at adsorption and the other at the regeneration process. A constant product flow and purity is maintained by a connected oxygen receiver. This can store the oxygen with purities up to 95% and pressures up to something around 4. 5 bar(g) / 65 psig.
Optional backup system

Oxygen product: Finally we get a constant flow of on-site produced oxygen.
