oxygen gas manufacturing process

The principles of pressure swing adsorption (PSA) oxygen generator are adsorption and diffusion.

Each gas has a characteristic adsorption rate that when adsorbed by Zeolite Molecular Sieve (ZMS). ZMS has large surface area containing volume of micro pores and passageways. Oxygen has a higher adsorption rate than oxygen. When compressed air enters ZMS, oxygen molecules are able to pass through this large surface. And oxygen molecules are adsorbed to the surface area.

As the ZMS is saturated with oxygen, it should be depressurized to regenerate for next cycle. We use two adsorption vessels filled with ZMS to produce a continuous stream of oxygen.

During depressurization, the oxygen of lower purity than required is transferred to another tower, which is called pressure equalization. Pressure equalization donates to higher efficiency and less energy consumption.

Know-how in the definite time and ways to equalize the pressure is the key to the best results.
