Oxygen Generation System With PSA/VPSA

Oxygen is the important industrial gas,widly used for the industry of steel, non-ferrous metal,chemical, Energy Saving Furnaces, environmental protection(sewage disposal, burn away the refuse etc), glass, paper making, medical treatment etc. Oxygen generation system with PSA/VPSA now becomes a new oxygen gerneration technology with its lower cost and extensive used.

Operational Principle Of The Oxygen Generation System with VPSA

This equipment use the process of vacuum pressure swing adsorption(VPSA for short), adsorb the nitrogen from the air with molecular sieve, separate and collect oxygen, create oxygen enrichment of 90-95% ,meanwhile,it can output the analysis which contain the nitrogen and other impurity gas, this is usually excluded into the atmosphere.

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

changeover 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
