ABSTRACT
The component of carbon molecular sieve (CMS) is carbon. CMS takes the appearance of cylindrical black solid, contains countless 4 angstrom fine pores, it can be used to separate air into nitrogen and oxygen. In industry, CMS can concentrate nitrogen from air with PSA systems. CMS products have the character of large nitrogen yield capacity; high nitrogen recovery. It can meet the requirement of all types of PSA nitrogen systems. This paper describes the results of the study the carbon molecular sieves CMS-240 and the adsorption process of a adsorption column in nitrogen gas generator using pressure swing adsorption. This equipment was fabricated and installed at Institute of Technology of the General Department of Defense Industry for simulation and optimization research.
