PSA NITROGEN GENERATORS Pressure Swing Adsorption (PSA)type Nitrogen Generation system that is used to separate and enrich Nitrogen from Oxygen employs CMS (Carbon Molecular Sieve) for adsorbent. Carbon Molecular Sieve (CMS) adsorbs Oxygen and Water Vapor molecules under certain pressure while allowing Nitrogen to pass through. The Nitrogen Generator is a Two-Bed Adsorber System The Nitrogen Generator consists of two adsorber vessels filled with CMS, a valve assembly, air filters, main pressure regulator, and a product receiver tank. Clean and dry air is directed to one of the adsorber beds where oxygen and water vapor is adsorbed faster than nitrogen in the pore structure of the CMS, thus increasing the nitrogen purity of the product gas stream to the desired level (95-99.999% as required by customer). This product flows out from the top of the adsorber bed, through the valve and into the product receiver at a pressure slightly below the feed air pressure.

For purities lower than 99,0%, it may be necessary to use an additional tank. (Buffer Tanks are standard for VNG 10 to VNG 2550) To determine the nitrogen generator model in the reference conditions divide the nitrogen flow rate to the factors mentioned above.
