The basic principle of PSA-CO technology is to use the adsorption selectivity of the adsorbent to adsorb CO in the mixed gas, and then to desorb CO by decompression or vacuumizing to achieve the CO separation. It can be seen from the comparison with the adsorption curve of 5A molecular sieve that the adsorption performance of the copper-loaded molecular sieve is more excellent. On o...

Vacuum pressure swing adsorption (VPSA) oxygen plants generally utilize the operating steps shown above to separate and enrich oxygen. In one cycle, each adsorption vessel needs to undergo five steps: "adsorption", "pressure reduction", "vacuum desorption", "Purging" and "pressure increasing". (1) Adsorption After mechanical impurities in the air is removed by the filter, it enters the ad...

VPSA (vacuum pressure swing adsorption) is separating oxygen from air by vacuum decompression for desorption. The pressure swing adsorption oxygen generation uses air as the feed gas which is forced by a blower to pass under pressure through the adsorbent bed. The nitrogen, carbon dioxide and water in the air are adsorbed by the adsorbent, and the remaining components pass through the absorb...

The oxygen-producing adsorbents mainly relies on its selective adsorption to nitrogen and oxygen penetrating function. They’re mainly divided into calcium-based CaA and CaX, and lithium-based LiX. CaA and CaX adsorbents are based on traditional molecular sieves used in the 1980s, therefore the cost is lower, but the energy consumption of producing oxygen is higher, therefore, total lo...

In the 1970s, Union Carbide Corporation industrialized pressure swing adsorption (PSA) oxygen generation technology for the first time using normal pressure desorption (PSA) process. The adsorbent was CaA adsorbent with low nitrogen adsorption capacity and high oxygen power consumption. In the 1990s, vacuum pressure swing adsorption (VPSA) oxygen production technology using LiX...

What is pressure swing adsorption? (technical principles) /What gases can be separated by pressure swing adsorption technology？ The basic principle of Pressure Swing Adsorption (PSA) is to use the difference of the adsorption characteristics of the gas components on solid materials and the change of adsorption capacity with pressure regulations, to achieve gas separation or purification ...

1.Based on Science & Technology at the Beginning In 1988, Xie Youchang, a professor at Peking University, developed a copper-based adsorbent with high selectivity for carbon monoxide based on the principle of spontaneous monolayer dispersion in basic research. The new adsorbent won US, Canadian and Chinese patents and was rated as the best known carbon monoxide adsorbent with muc...

In celebration of establishing 30 years,the China General Machinery Industry Association (hereinafter referred to as “CGMA") held an festivity in Shenyang on October 16, 2019. The event commended outstanding enterprises in the general machinery industry, and specially set up 5 prizes for “Outstanding Contribution Award for Major Equipment”, “Special Advantageous Enterprise...
