PSA technology has gradually spread to other gas separation processes with great success. In refineries, multi-bed PSA units are capable of efficiently separating pure hydrogen gas from synthesis gas and other similar gas streams. Another well-known PSA application is for the purification of helium gas to greater than 99.999% purity. Azota has long recognized the potential of this technology in the natural gas processing industry where it has largely been ignored. Areas of application are the removal of CO2, the separation of nitrogen gas in small nitrogen rejection applications, and the dehydration of natural gas for further processing. These applications are well served using various treating and cryogenic processes, but a need exists for simpler methods that may be applicable to smaller gas plants.

The untapped potential of this technology for the midstream industry awaits the innovation which Azota has always provided. The technical hurdles for newer applications require the resources of careful engineering and research. Our process engineers have designed our PSA pilot unit which can operate over a very wide range of conditions to produce reliable data for all of the gas separation that need a simpler, better solution.
