PSA Nitrogen Plant

Veecon-IPA Gastechnik Ltd. offers PSA Nitrogen Plant. Carbon Molecular Sieve (CMS) is the main stream adsorbent for PSA nitrogen gas generators. It is a differential diffusion rate system based on the fact that the oxygen molecule is smaller than the nitrogen molecule.

A special CMS adsorbs oxygen gas, carbon dioxide gas, moisture and so on in compressed air in a short period of time & compressed nitrogen gas is obtained at the outlet. When the pressure is removed to the atmospheric or vacuum level, CMS, which has adsorbed oxygen gas and others easily desorbs them and is regenerated.

When the above two operations are done alternately between two adsorpton columns, nitrogen gas can be separated continuously from the air.

Veecon IPA offers non-cryogenic pressure swing adsorption (PSA) based on-site nitrogen plant, in collaboration with Kuraray Chemicals Ltd., Japan, a world renowned global company.

Since 1940 intensive research and development efforts have ensured that high purity nitrogen (99.99% N2 + Ar) gas separation directly from air. Further nitrogen purification is done by catalytic purification.
