PSA Principle

PSA ( Pressure Swing Adsorption ) is an advanced gas separation technology, based on the physical adsorption of the internal surface in the adsorbent to gas molecules, separating the gas by the characteristics of absorbing to the quantity of different gas in general pressure.

The CMS (carbon molecular sieve) is a sorbent picked up from the air, used in separating oxyen and nitrogen molecular. As picture shown, the adsorption quantity of CMS is greatly higher to oxygen than nitrogen does with the same pressure.

PSA nitrogen generator produces N2 gas, using air as raw materials and carbon molecular sieve as adsorbent, by the selective adsorption of carbon molecular sieve to O2 and N2, achieving the separation of the N2 and O2 in the air.

PSA nitrogen generator, have the characteristics of simple technological process, facilitate operation, high degree of automation, fast production (15’ to 30’ min), low consumption, high purity, and the purity of product can be regulated in the larger scope according as user’s need. Because of many advantages of this product, PSA nitrogen generator has become the first choice of small and medium-sized users below 3000Nm3/h demands.
