teknolojiya VPSA da PSA
Takadduniyar VPSA (Vacuum Pressure Swing Adsorption) da PSA (Pressure Swing Adsorption) ya kara biyu aiki maimakon da ke danna daidai fiye ne a cikin rubutun saukarwa gas da wataƙen wannan. Wannan da PSA ya kamata aiki na tsarin gaba, VPSA ya tafiya mai shirin tabbatar da hanyar daidai. PSA ya gabatar da rubutun gas a cikin samfuri da aka yi amfani da takardun wadannan a matsayin 2 da 4 bar. A kanannan, VPSA ya tambaya wannan amfani da yankin wadanda, ya gabatar da takardun gas a matsayin 0.3 da 0.5 bar absolute. Hakaɗi na farko suna ya yi amfani da VPSA samfuri da aka yi amfani da takardun wadannan da aka yi amfani da yankin wadanda. Takadduniya ya tambaya amfani da material adsorbent mai shirin da aka yi amfani da wannan a matsayin takardun wadannan. A cikin amfani, VPSA samfuri da aka yi amfani da sabon hakken da aka yi amfani da takardun wadannan, adsorption, depressurization, da vacuum regeneration phases. Wannan amfani ya yi amfani da wataƙen saukarwa gas mai shirin, misali oxygen a cikin air, da wannan a matsayin recovery rates ya kawo 90 percent ko binciken. Takadduniya ya tambaya amfani da sabon hakken a cikin samfuri da aka yi amfani da gas na sabon hakken, labarai na fita, labarai na wadannan da aka yi amfani da gas na sabon hakken.
