General Introduction to Pressure Swing Adsorption Technology
Normal air separation technology is the newly- developed technology in foreign countries in the 1970s, which is totally different from the traditional cryogenic air separation technology. In our region the Group is the earliest company, which started to research the pressure swing adsorption technology in 1982. For this the project has been listed in the C°Key Science Project in the Sixth five year plant. Therefore, Group research institute set up a research team for pressure swing adsorption technology development. The first 50m3/h industrial device was passed the qualification by China ministry of machine building in 1987. So far, the normal temperature gas separation plant has been widely used in petrochemical, metallurgical, chemical, coal, electronic and food industry. The normal temperature air separation plant of Group (pressure swing adsorption to make oxygen, pressure swing adsorption to make nitrogen and membrane separation to make nitrogen) is chosen as the main matched product of logistics equipment for PLA air force and the second artillery troop.
Group has made great contribution to the modernization of Chinas’ defense.
