Gas separation by non cryogenic processes.

La séparation des gaz par procédés non cryogéniques.

Author(s) : MONEREAU C.

Type of article: Article


The two non-cryogenic processes of gas separation are described: a) pressure modulated adsorption (Pressure Swing Adsorption or PSA process), based on the differences in the adsorption capacity of adsorbents for the different gases, and on the variations in the capacity as a function of pressure. The separation of nitrogen from air, the separation of oxygen and the purification of gases containing hydrogen are described; b) the permeation through a polymer membrane, based on the differences, between different gases, in the permeability of a membrane comprising a bundle of hollow fibres having the diameter of one hair. Nitrogen, oxygen and hydrogen production is decribed. J.R.
