Carbon molecular sieve (CMS) is a new and one of the few non-polar adsorbent that specializes in separating oxygen from nitrogen under the normal temperature and pressure, also it is an important part in natural gas processing. This process is done with a PSA (Pressure Swing Adsorption) device. Carbon molecular sieve can adsorbing material with molecular size less than 10 angstroms, which normal activated carbon can not do accurately. Carbon Molecular sieve can be applied in many different fields, such as petroleum chemical industry, metal heat treatment, electronic, and as preservative in food products etc.Our CMS products have the characters of high nitrogen yield capacity and nitrogen recovery rate which can meet all types of PSA nitrogen systems requirements.
PSA Nitrogen System Introduction
The technology of air-to-nitrogen production with the use of adsorption processes in nitrogen generators is well studied and widely applied at industrial facilities for the recovery of high-purity nitrogen.
The operating principle of a nitrogen generator utilizing the adsorption technology is based upon the dependence of the adsorption rates featured by various gas mixture components upon pressure and temperature factors. Among nitrogen adsorption plants of various types, pressure swing adsorption (PSA) plants have found the broadest application world-wide.
Why Use Our Carbon Molecular Sieves(CMS)?
High nitrogen purity
PSA nitrogen generator plants allow production of high-purity nitrogen from air, which PSA membrane systems are unable to provide – up to 99.9995% nitrogen. This nitrogen purity may also be ensured by cryogenic systems, but they are considerably more complex and justified only by large consumption volumes. The nitrogen generators use CMS (carbon molecular sieve) technology to produce a continuous supply of ultra high purity nitrogen and are available with internal compressors or without.Also, the Carbon Molecular Sieves is lower cost than membrane technology.
Low operating cost
The PSA process offers a low cost, on-site supply of gaseous nitrogen for the blanketing of storage tanks, pipelines and tankers, the processing of plastics and fibres, the storage and packaging of perishable foods and beverages, the heat treatment of metals, or applications in the electronics industry.
SINOCATA offers products with outstanding performance for PSA-based nitrogen generation, biogas upgrading, nitrogen rejection and hydrogen refining.
