Description

N2 Gas Generation System Psa Nitrogen Generator Machine for Food Packaging

PSA Nitrogen Generator produces N2 gas, using air as raw materials and carbon molecular sieve as adsorbent, by the selective adsorption of carbon molecular sieve to O2 and N2, achieving the separation of the N2 and O2 in the air.

The Principles of PSA Nitrogen Generator

PSA( Pressure Swing Adsorption) is an advanced gas separation technology, based on the physical adsorption of the internal surface in the adsorbent to gas molecules, separating the gas by the characteristics of absorbing to the quantity of different gas in general pressure. The CMS (Carbon Molecular Sieve) is a sorbent picked up from the air, used in separating Oxygen and Nitrogen molecular. The absorption quantity of CMS is greatly higher for Oxygen than Nitrogen under the same pressure.

Principle introduction:
PSA nitrogen generator uses air as raw material, carbon molecular sieve as adsorbent, uses the principle of pressure swing adsorption, and uses the method of selective adsorption of oxygen and nitrogen by carbon molecular sieve to separate nitrogen and oxygen, and produces nitrogen automatic equipment.
The carbon molecular sieve is based on the slight difference between the kinetic diameter of O2 and N2 to achieve the separation of nitrogen and oxygen, and the kinetic diameter of the oxygen molecule is smaller, so there is a faster diffusion rate in the micropores of the carbon molecular sieve. The kinetic diameter of the nitrogen molecule is larger, so the diffusion rate is slower, and the final enrichment from the adsorption tower is high-purity nitrogen.
