OXYGEN production by PRESSURE SWING ADSORPTION (PSA)

Oxygen is produced in large volumes for many applications. Perhaps the commonest of these are in medicine and in the pulp and paper industry. There are two methods used for doing this: cryogenic and pressure swing adsorption. Pressure swing adsorption is most useful for small applications such as oxygen production in the home for asthma sufferers.

Pressure swing adsorption relies on air being filtered through aluminosilicate minerals known as zeolites. The one used for PSA oxygen has been specially designed so that nitrogen gas is adsorbed onto it while oxygen (and argon) pass straight through. The zeolite is quickly saturated with nitrogen, so two zeolite beds are usually used together, one filtering air while the other is regenerated. This process is very environmentally friendly and the technique is also potentially able to be used to remove other gases (such as CO2) from industrial waste gas streams.

Zeochem AG offeres a full range of zeolites on ion basis, such as NaX, LiX and Li-LSX for the best possible customer solution. Since the application in huge for medical oxygen concentrators and industrial units as well (e.g. for fish farming, gold mines, etc) please contact our specialists.

ZEOX® Z10-04 is installed in PSA Oxygen units to produce concentrated oxygen from air.

ZEOCHEM® Z10-05-03 and ZEOX Z12-07 are Li-LSX version for both, industrial and small scale oxygen units. (both are for the production of high purity oxygen)

ZEOX® OII was developped especially for the use in small scale medical oxygen concentrators.
