How a PSA Nitrogen Gas Generator Works
Working Principle
The air that we breathe on earth is made up of 78 % nitrogen and 21 % oxygen. Air also has other inert gases in very small quantities.
The pressure swing adsorption(PSA) process is designed around two or more adsorber towers which are filled with carbon molecular sieve material. An Air compressor is used to supply compressed air which is further treated with a refrigerated dryer to reduce the air dewpoint to +3 to +5 Deg C & set of filtration to make compressed air completely free of any heavy particulate & oil contaminations. Dry & oil-free air then enters the adsorber tower where carbon molecular sieve material has a strong affinity for oxygen & water molecules therefore these molecules get adsorbed to the CMS porous surface under pressure and pure nitrogen gas is collected & stored in a storage tank at the outlet. when one tower is under adsorption, another tower is regenerated by reducing the tower pressure close to atmospheric pressure to release the adsorbed gases and allowing a small amount of pure nitrogen gas as purging gas to remove any oxygen impurities, the cycle repeats itself to produce nitrogen gas continuously.
How a Membrane Nitrogen Gas Generator Works
Working Principle
Gas separation membranes work according to the principle of selective permeation through the membrane surface. The permeation rate of each gas depends on its solubility in the membrane material and on the diffusion rate of the gas. Gases with high solubility and small molecules such as oxygen & water vapor pass through the membrane very quickly & permeate through the fiber walls. Less soluble gas such as Nitrogen with larger molecules takes more time to permeate the membrane, as a result, enriched nitrogen exits as product gas.
