Oxygen Plant

PSA BASED ON SITE OXYGEN GENERATION SYSTEM


How it Works?

Normally an Air contains 21% Oxygen, 78% Nitrogen, 0.9% Argon and 0.1% other trace gases. A unique process called Pressure Swing Adsorption(PSA) is used in Our Oxygen generator which separates the oxygen from Compressed Air.

The synthetic Zeolite Molecular Sieve is used to absorb mainly nitrogen, we thus use this ability for the generation of enriched oxygen gas from ambient air. This process is called as The Pressure Swing Absorption process. On completion of this process the Zeolite concentrates the nitrogen in the pore system which in turn Produces Oxygen as a Product.

Oxygen generation plant’s use two vessels filled with Zeolite Molecular sieve as absorbers. As Compressed Air passes up through one of the absorbers, the molecular sieve selectively absorbs the Nitrogen. This then allows the remaining Oxygen to pass on up through the absorber and exit as a product gas. When the absorber becomes saturated with Nitrogen the inlet airflow is switched to the second absorber.

Produced Oxygen Purity is 93.3% to acheive that The first absorber is regenerated by desolving nitrogen through depressurization and purging it with some of the product oxygen. The cycle is then repeated and the pressure is continually swinging between a higher level at adsorption (Production) and a lower level at desorption (Regeneration).


The oxygen generator systems are perfect for anyone who wants their own supply of oxygen while not compromising on the quality with flexibility and reliablity. When you need to produce the gas, our Oxygen Generators allow you to produce specifically wherever you need it be produced.

Operation Principles:

Drying Cycle: The Moisture and oil free air which in terms called as Purified air from the compressed air systems, will be Passing through one of the tower filled with Molecular Sieves (Zeolite type). The Molecular sieves will specifically absorb the nitrogen, allowing oxygen to pass through at the selected set of purity level.

Regeneration Cycle: During regeneration cycle, the sudden depressurization brings out nitrogen molecules strapped in the sieve’s pores to the surface of the beads. Small portion of oxygen from the drying tower is passes over the sieves through the regeneration orifice. This results in complete regeneration of Molecular Sieves. The automatic cycling of the adsorption and desorption between the two beds enables the continuous production of oxygen.

Detailed design of process parameters followed by extensive validation has resulted in consistent performance in Oxygen Series. Highly reliable PLC based controller with digital display of generator operations.
