Carbon Molecular Sieve

Carbon Molecular Sieve (CMS) is used to separate Oxygen and Nitrogen in Nitrogen gas production units by PSA method to increasing Nitrogen purity.

In this process, compressed air is directed alternately to two containers filled with CMS sieves which capture the oxygen molecules. What is left is high-purity nitrogen. As well as nitrogen production, CMS sieves are also used in biogas refinement and in noble gas recovery. When the pressure is high enough, the oxygen molecules, which pass through the pores of CMS much faster than the nitrogen molecules, are adsorbed, while the coming out nitrogen molecules will be enriched in gas phase. The enriched oxygen air, adsorbed by the CMS, will be released by reducing the pressure. Then the CMS is regenerated and ready for another cycle of producing nitrogen enriched air.
