PSA Nitrogen Generation Porcess

- Feb 28, 2019 -

Carbon Molecular Sieve  is a mainstream adsorbent for Pressure Swing Adsorption (PSA) system Nitrogen gas generator. There is a differential diffusion rate system based on the fact that the oxygen molecule is smaller than the nitrogen molecule. CMS adsorbs oxygen gas, carbon dioxide gas, moisture and so on in compressed air in a short period of time and compressed nitrogen gas is available at the outlet. When the pressure decreases to the atmospheric or vacuum level, CMS which has adsorbed oxygen gas and others easily desorbs them and is regenerated. When the above two operations are done alternately between two adsorption columns, nitrogen gas can be available continuously from the air.
