PSA oxygen generators utilize the well-known and mature Pressure Swing Adsorption technology. Atmospheric air comprises of 20-21% oxygen and the PSA process utilizes Zeolite molecular sieves to extract this Oxygen from air. Oxygen at 95% is delivered, while the nitrogen adsorbed by the molecular sieves is vented back into air through the exhaust line. PSA process consists of 2 vessels filled with Molecular Sieves and Activated Alumina. Clean compressed air at 30° C temperature is passed through one vessel and oxygen comes out as product gas. The exhaust gas (Nitrogen) is discharged back into atmosphere. Upon saturation of the molecular sieve bed, the process switches Oxygen generation to the other bed by automatic valves, while allowing the saturated bed to undergo regeneration by depressurization and purging to atmospheric pressure. Thus 2-vessels keep cycling alternately in Oxygen production and regeneration ensuring Oxygen gas is continuously available to your process.
