(Capacity 0,2Nm3/h – 2500Nm3/h; Purity 95 % - 99,999 %)

How It Works?

Pressure Swing Adsorption (PSA) type Nitrogen Generation system is used to separate and enrich Nitrogen from Oxygen employs CMS (Carbon Molecular Sieve) for adsorbent. Carbon Molecular Sieve (CMS) adsorbs Oxygen and Water Vapor molecules under certain pressure - while allowing Nitrogen to pass through.

The nitrogen molecules (4.3 Angstrom in size) passes through the column, but the oxygen molecules (3.9 Angstrom in size) are adsorbed on the carbon molecular sieve (4 Angstrom opening). 

The cycle is composed of following steps

PSA Process

A. Pressurization Step:

Process to increase adsorption pressure in adsorption tower under selected operation condition.

B. Adsorption Step:

Nitrogen gas is generated under constant pressure.

C. Blow Down Step:

Restoring in the adsorption tower.

D. Purge Step:

Stage to restore the adsorption tower completely.

E. Pressure Equalization Step:

Stage in where loss can be reduced by using a part of energy to be lost.

Adsorber System

The Nitrogen Generator consists of two adsorber vessels filled with CMS, a valve assembly, air filters, main pressure regulator, and a product receiver tank. Clean and dry air is directed to one of the adsorber beds where oxygen and water vapor is adsorbed faster than nitrogen in the pore structure of the CMS, thus increasing the nitrogen purity of the product gas stream to the desired level (95 – 99.999 % as required by customer). This product flows out of the top of the adsorber bed, through the valve, and into the product receiver at a pressures lightly below the feed air pressure.
