PSA Nitrogen Generator system is a technical equipment in which air is used as raw material and a highly efficient and highly selective solid adsorbent (carbon molecular sieve) is used to perform selective adsorption on nitrogen and oxygen, separating nitrogen and oxygen from the air. The separation effect of carbon molecular sieve on nitrogen and oxygen is mainly based on the difference in the diffusion rate of the two gas molecules in the carbon molecular sieve, the smaller diameter of the gas (oxygen) molecules diffusion faster, more into the molecular sieve solid phase. So you get a nitrogen enriched component in the gas phase. About 2min, the adsorption of oxygen molecular sieve reached a balance, according to the carbon molecular sieve under different pressure on the adsorption of gas adsorption of different characteristics, reduce the pressure to carbon molecular sieve to release the adsorption of oxygen molecules, this process is called regeneration. Pressure swing adsorption usually uses two towers in parallel, alternating compression adsorption and step-down regeneration to obtain continuous nitrogen.
