PSA Oxygen generation is based upon the adsorption technology which is a physical separation process using different adsorption affinities of gases to a micrporous solid substance ,called molecular sieves. Nitrogen has a higher adsorption capacity to zeolite molecular sieves of special grade than oxygen. This characteristic is used with the PSA plants for generation of plants
