How does a pressure swing adsorption nitrogen generator produce high quality nitrogen?
- Nov 13, 2018 -

The pressure swing adsorption nitrogen generator is designed and manufactured using advanced production technology. The machine uses the principle of pressure swing adsorption to extract nitrogen from compressed air. The adsorption unit uses a special adsorption material called carbon molecular sieve.

 

During the operation of the pressure swing adsorption nitrogen generator, due to the large amount of micropores distributed on the surface of the adsorbent material, the diffusion rate of oxygen and nitrogen on the carbon molecular sieve is different under a certain pressure due to the kinetic effect. The molecules are adsorbed by the carbon molecular sieve in a large amount, and the nitrogen molecules are gas-phase enriched, thereby achieving the purpose of oxygen-nitrogen separation.

 

In addition, the adsorption capacity of carbon molecular sieve for oxygen will change to varying degrees due to the change of pressure. The pressure can be desorbed to desorb the oxygen molecules adsorbed by the carbon molecular sieve, so that the carbon molecular sieve can be regenerated and reused. The pressure swing adsorption type nitrogen generator adopts two sets of adsorption tower processes, one group adsorbs nitrogen, one tower desorbs and regenerates, and the cycle alternates to continuously produce high quality nitrogen.http://www.cnrelita.com/
