Pressure Swing Adsorption, or PSA, is a technology used to separate some gas species from a mixture of gases under pressure. Pressure swing adsorption nitrogen generation is based on the theory that gases subjected to high pressures tend to be attracted to solid surfaces, or adsorbed. This process can be used to separate gases in a mixture because different gases are attracted to different solid surfaces to varying degrees.
With a PSA Nitrogen Generator, the air is separated by compression on a bed from carbon molecular sieve, also known as a CMS, which preferentially adsorbs the oxygen. At the same time, in a second drum of the CMS, the pressure is lowered; this leading to adsorbed oxygen which is exhausted. This bed of CMS, now denuded of oxygen, is again ready for a further compression cycle of adsorption.
Carbon molecular sieve has a much narrower range of pore openings than ordinary activated carbons. This allows small molecules, such as oxygen, to penetrate the pores and be separated from nitrogen molecules which are too large to enter the CMS. The larger molecules of nitrogen, therefore, bypass the CMS and emerge as the product gas within the nitrogen PSA unit.
