Carbon Molecular Sieve used in the PSA Nitrogen generation, the Nitrogen generation by Pressure Swing Adsorption (PSA) process is a technology used to separate nitrogen from a mixture of gases under pressure according to the special selective adsorption characteristics of the Carbon Molecular Sieves (CMS).
The Carbon molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases. 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.
Physical properties
Diameter of the CMS granule: 1.8~2.0mm
Period of adsorption: 120S
Bulk density: 680-700g/L
Compressive strength: ≥ 95N/ granule
Service scope
The following merits of service:
High ratio performance & price, reducing investment cost and operation cost.
Large hardness, little ash, long service life, uniform particles which protests air current impact.
Stable quality: Testing strictly according to 100% standard of production and ex-factory testing management.
The resin uses in producing the high pure nitrogen with good performance which substitutes the similar import products.
PSA Nitrogen Generation Process
1) Air Feed System
The environmental air supplied to the PSA system should be compressed and purified to get rid of the dust, the oil and water.
2) PSA Nitrogen Generation System
While the compressed and purified air flows through the adsorbent bed with CMS inside in a bottom up way under the pressure of 0.6MPa, the oxygen molecules will be adsorbed by the solid surfaces of the CMS, and the enriched nitrogen will be output from the top of the bed to the container.
When the adsorbent bed reaches the end of its capacity to adsorb oxygen, it can be regenerated by reducing the pressure, thereby releasing the adsorbed oxygen. Using two adsorbent beds to absorb and regenerate in turn allows producing continuous nitrogen in cycle.
Packing: By plastic drum, each drum 20kgs net, palletized with wrapped

Nantong Skyland Industrial And Trade Co., Ltd is a special enterprise for production of molecular sieve, activated alumina, catalysts and attapulgite, It is one of the biggest private enterprise in scale of production in the same industry in China. The first-class production workshop, the first-rate office installations, convenient transportation construct our rich enterprise culture. In 2009, we have a large production base additional, located in Mingguang Industrial Zone, Anhui Province. The production base covers an area of 22 acres, with over 6 millions USD of investment, owns high-grade mines and 2 production lines. We operates strictly under the requirement of ISO9001: 2000 and ISO14001.
Advanced checkout equipments are guarantee of quality, and outstanding human resources are impetus of business development. Engineering staffs with the proportion of 23% of the employed actively work in the front line of development. Strong developing technological capability of Shanghai Chemical Engineering Institute and Nanjing University is vitality of continuously progress of the enterprise.
Continuously innovating and throwing away the old and decayed not only make conventional products advance rapidly, but also form new key products, for example, PSA-O2(VSP), XH series, nickel base, argentums base, palladium base catalysts will all become new point of growth.
More than that our industry popularity and comprehensive strength stand the first places in China because we not only own more than 30-year operating experience of Chinese molecular, but absorb advanced technologies of American UOP. Hence our consumer group is extending to foreign countries, now there are our partners in Southeast Asia, Europe, Middle East and America. We believe that our enterprise must have a brighter tomorrow.
