Oxygen production by Pressure Swing Adsorption (PSA)

Oxygen is traditionally produced by cryogenic distillation, which is a capital intensive process economical for large volume plants. The adsorption process, widely called PSA, can be used to generate oxygen and is very attractive and more competitive than the cryogenic process for small oxygen production.

Another advantage is that it can be used in remote locations which are not connected to an oxygen grid. In this process, air is passed through at least one column where components like nitrogen (N2), carbon dioxide (CO2) and water (H2O) are better adsorbed than oxygen (O2) and argon (Ar). The oxygen produced can reach a purity level of 90% or more.

Arkema has developed several products under the Airsiev® brand to supply the oxygen PSA industry.
