Principles of PSA Oxygen Generator
P S A Technology is based on the selective adsorption phenomena of gas molecules under pressure on the surface of highly porous and efficient adsorbent; In this case of Oxygen Generation the Adsorbent is zeolite based Molecular Sieve (Z.M.S.)
In P S A System when compressed air is passed through a adsorption tower field with Z.M.S. the molecules of oxygen, moisture & other unwanted gases are adsorbed on surface of Z.M.S. and Oxygen which is not adsorbed by Z.M.S. comes out of adsorption tower and is collected in a surge vessel.
For continuous generation of oxygen two Adsorption towers are provided which are interconnected with Auto-change over valves controlled by PLC in the control panel. After saturation of one tower with nitrogen the process automatically changes over to another tower and thus the oxygen production is continuous.
Atmospheric oxygen pressure swing adsorption and desorption are at slightly higher pressure (0.35Mpa ~ 0. 8Mpa) of adsorption, desorption emptying at normal pressure.
Our systems are the best ones in industry to ensure the highest efficiency, user-friendly design, reliable economical and durable. Our onsite oxygen generators are custom made and can be adjusted to give the desired oxygen quality for your process and application.
