How PSA Nitrogen Generators Work

CANGAS Systems Company Limited | Updated: Dec 21, 2015

How PSA Nitrogen Generators Work

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

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

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

During depressurization, the nitrogen 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.
