PSA Nitrogen Generator Working Principle
The PSA Nitrogen generator is based on the principle of pressure swing adsorption, using high-quality carbon molecular sieve as adsorbent, under a certain pressure, to produce nitrogen from the air. The purifying and drying compressed air is adsorption and desorption in the adsorber. Since the diffusion rate of oxygen in the micropores of carbon molecular sieve is much higher than that of nitrogen, oxygen is preferentially adsorbed by carbon molecular sieve, and nitrogen is enriched to form product nitrogen. Then by reducing pressure to normal pressure, the adsorbent desorbs the adsorbed oxygen and other impurities to achieve regeneration. Generally, two adsorption towers are set up in the system, one tower adsorbed nitrogen, the other tower desorption regeneration, through the PLC program controller to control the opening and closing of the pneumatic valve, so that the two towers alternate circulation, in order to achieve the purpose of continuous production of high-quality nitrogen
