99% Purity Psa Oxygen Generator Vpsa Oxygen Production Equipment

PSA (Pressure Swing Adsorption) technology is a revolution in Non Cryogenic Air Separation and Oxygen Generation technology that uses a 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.

The PSA generator can be operated under normal atmosphere, and its advantages are listed as following:

• Low Production Cost
• Simple Process and Less Equipment, High Automation and Operation Convenience
• Quick starting and easy stopping. The system can provide product gas in 30 minutes after starting and also can be operated intermittently
• Low working pressure and safely
• Good flexibility. The purity and output for oxygen can be easily adjusted
