PSA Nitrogen Generator

PSA Nitrogen Generator


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 absorber 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 absorber bed, through the valve and into the product receiver at a pressure slightly below the feed air pressure.

*The purity and capacity of nitrogen gas is designed to meet customer requirements(Nitrogen Purity 95%~99.999% is available)

– Minimum maintenance cost.

*Replace filter element periodically only and service your compressor as normal

Note: Mikropor supplies buffer tank volumes for 99,0% and

higher Nitrogen purities. For purities lower than 99,0%,

it may be necessary to use an additional tank.
