PSA nitrogen generator principle
PSA nitrogen generator and PSA oxygen generator have similar principle. Molecular sieve as an adsorbent under the principle of pressure swing adsorption (PSA), will get nitrogen/oxygen from compressed air.According to the performance of molecular sieve, its adsorption when pressure risen and desorption when pressure loose. Molecular sieve's surface and inner surface and interior are filled with micro pores. Oxygen molecule has a faster diffusion rate of molecular sieve and nitrogen molecules has a slower diffusion rate. Nitrogen molecules are enriched in the end from the absorption tower. Nitrogen generator is constructed according to the principle of operation PSA (pressure swing adsorption) and it compressed by two absorption towers filled up with molecular sieve. The two absorption towers are crossed by compressed air (previously purified oil, water,dust, etc) . While one of the absorption tower produce nitrogen, the other one release oxygen gas to atmosphere. The process comes in cycle way. The generator is controlled by PLC.
Perfect process design get high performance. Unique vacuum molecular sieve filling system and impacted technology increase the life of molecular sieve. Skid-mounted structure makes installation and transportation more convenient. With DCS controller system and remote output and control system. High automatic, unmanned operation.
