PSA Oxygen Gas Generator

PSA Oxygen Gas Generator / Plant manufactured by MGS offer low-cost Oxygen with a highly reliable supply alternative.

We offer a wide range of Oxygen PSA Systems to suit individual client's requirement. The process parameters are optimized to meet specific flow, purity and pressure.

PSA Oxygen generation is based upon the adsorption technology which is a physical separation process using different adsorption affinities of gases to a micrporous solid substance ,called molecular sieves. Nitrogen has a higher adsorption capacity to zeolite molecular sieves of special grade than oxygen. This characteristic is used with the PSA plants for generation of plants .

The method of generating oxygen from oxygen gas plant involves taking air from an air compressor. It has 2 vessels feeded with special grade of molecular sieves. Clean compressed air at an ambient temperature is passed through one vessel and oxygen comes out as product gas and other vessel is de pressurized to atmospheric pressure and purge with little quantity of oxygen coming out from first vessel. This regenerates molecular sieves which is used in next cycle. Thus second vessel keeps cycling alternately in oxygen production and regeneration making oxygen gas available continuously to PSA oxygen unit.

MGS Oxygen Pressure Swing Adsorption (OPSA) Systems offer low-cost Oxygen with a high supply alternative.
