PSA Oxygen Generator

Product introduction

PSA ( Pressure Swing Adsorption) Technology a revolution in Non Cryogenic Air Separation and Oxygen Generation Technology uses special grade of ZMS ( Zeolite Molecular Sieve). The compressed air is passed through a Twin Tower PSA module interconnected with automatic change over valves. After passing through a Refrigerated Dryer air gets dried. Dried compressed air will now come in contact with bed of Zeolite molecular sieves (ZMS). Zeolite Molecular Sieves are special grade of adsorbent which have the property of preferential adsorption of nitrogen molecules. At a time one tower remains under nitrogen production cycle, whereas the other tower undergoes regeneration which is achieved through depressurization of the tower to atmospheric pressure. The outgoing oxygen gas is sent to a surge vessel where the minimum pressure will be maintained with the help of Back pressure Regulator.

Based on the principle of pressure swing adsorption (PSA), zeolite molecular sieves are used as the adsorbent. Due to the selective adsorption characteristics of zeolite molecular sieves, nitrogen is largely adsorbed by the molecular sieves, while oxygen is enriched in the gas phase, achieving ammonia-oxygen separation under the action of PSA. A dual-tower or multi-tower structure is adopted, with oxygen adsorption and desorption/regeneration occurring simultaneously. The opening and closing of pneumatic valves are controlled by intelligent programs such as PLCs, allowing the two or more towers to circulate alternately, continuously producing high-quality oxygen.
