On-Site Gas Generation Advantage

Our Technology : PSA

Nitrogen gas is extracted from the atmosphere, which consists of 78% Nitrogen. Adsorbtech Nitrogen Generators extract Nitrogen gas from the atmosphere using Pressure Swing Adsorption (PSA) technology.

The PSA Process consists of 2 interconnected PSA Towers filled with Carbon Molecular Sieve (CMS) – a carbon-based chemical containing microscopic pores on its surface.

Clean and dry compressed air enters the PSA System. Here, Oxygen molecules are trapped by CMS and only Nitrogen gas molecules proceed further into the On-site Generation process.

You now have pure, clean Nitrogen as your product gas.

PSA based Nitrogen generation is a non-explosive, non-cryogenic method that does not require government permission. Customers save time and effort by avoiding such formal processes.

What Is PSA?


Nitrogen-rich compressed air enters one PSA tower at a high pressure. Compressed air pressure enables the CMS chemical inside the PSA tower to produce high purity Nitrogen.


The two PSA towers, filled with CMS, are pressurized alternately after 60 seconds. The air pressure swings from Tower 1 to Tower 2 during the time cycle. The swing cycle is necessary to regenerate the CMS since it becomes saturated with Oxygen molecules after 60 seconds.Automatic valves operate the swing process, the valves are tested for several thousand cycles.


Adsorption is a surface level reaction in which molecular pores on the surface of CMS trap Oxygen molecules.Once oxygen molecules are trapped, Nitrogen molecules are free to flow out of the PSA tower.After 60 seconds, Nitrogen generation stops and the oxygen molecules are released to the atmosphere when the pressure swings in the PSA system.
