Oxygen is a very important gas in industry fields, it’s widely used in steel, non-ferrous metallurgy, chemical industry, furnace energy saving, glass, sewage treatment, garbage incineration, etc. VPSA oxygen generation is the highest efficiency, lower energy consumption.
VPSA system is mainly composed of blower, vacuum pump, switching valve, adsorber and oxygen balance tank. Feed air after the dust particles are removed through the suction filter, they are pressurized to 0.3-0.5 bar by blower and enter one of the adsorbers inside. The adsorber is filled with adsorbent and dehydrating agent, in which water, carbon dioxide and a small amount of other gas components are introduced into the adsorber. The impurities is adsorbed by the activated alumina filled at the bottom, and then nitrogen is adsorbed by the zeolite molecular sieve filled at the upper part of the activated alumina adsorbent. Oxygen which is discharged to the oxygen balance tank as product gas form the top outlet of the adsorber. While the adsorbent reaches saturation, the moisture, Co2, Nitrogen and other gases will be regenerated by vacuum pump.
CHEMXIN XCLX-01/XCLX-02 are the best materials for VPSA system. It is the lithium form aluminosilicate with X type crystal structure. And it is specially developed and designed molecular sieve for oxygen production from air with international advanced level. It is mainly used in PSA and VPSA oxygen concentrator device. Having the characteristics of higher N2 adsorption capacity, high N2 with O2 selectivity and easy desorption etc. Its N2 adsorption capacity is 2-3 times larger than A type oxygen enrichment molecular sieve bed. At the same time, this Lithium Molecular Sieve has good wear resistance and longer service life. It can significantly increases the economic benefits of oxygen production by lowering operating costs and energy consumption. Normally, CHEMXIN Lithium Molecular Sieve model XCLX-01 is designed for portable oxygen generator 1-5L/Min, CHEMXIN Lithium Molecular Sieve model XCLX-02 is designed for industrial oxygen plant, oxygen purity is up to 93%±3%.
