Ibintu nyamukuru bigize umwuka ni azote (78%) na ogisijeni (21%), bityo rero twavuga ko umwuka ari isoko idashira yo gutegura azote na ogisijeni.PSA igihingwa cya ogisijeni.Azote ikoreshwa cyane cyane muri ammonia yubukorikori, ikirere kirinda ubushyuhe bwicyuma, inert ikingira ibicuruzwa biva mu miti (gutangiza no guhagarika imiyoboro ya azote, gufunga azote ibintu byoroshye okiside), kubika ingano, kubika imbuto, inganda za elegitoroniki, nibindi. Oxygene ni ikoreshwa cyane nka okiside muri metallurgie, gazi yingoboka, kuvura, gutunganya amazi mabi, igitutu swing adsorption uruganda rwa azote ninganda zikora imiti.Nigute ushobora gutandukanya umwuka uhendutse kugirango ubyare ogisijeni na azote nikibazo cyigihe kirekire cyizwe kandi gikemurwa naba chimiste.
Azote yuzuye ntishobora gukurwa muri kamere, bityo gutandukanya umwuka nibyo guhitamo kwambere.Uburyo bwo gutandukanya ikirere burimo uburyo bwubushyuhe buke, uburyo bwa swing adsorption nuburyo bwo gutandukanya membrane.Hamwe niterambere ryihuse ryinganda, azote yakoreshejwe cyane mubikorwa bya chimique, electronics, metallurgie, ibiryo, imashini nizindi nzego.Ubushinwa bukenera azote buriyongera ku gipimo kirenga 8%.Ubuhanga bwa chimie ya azote ntabwo bugaragara.Ntabwo ari inert cyane mubihe bisanzwe kandi ntabwo byoroshye kubyitwaramo nibindi bintu.Niyo mpamvu, azote ikoreshwa cyane nko kubungabunga Gazi no gufunga gaze muri metallurgie, electronics, inganda zikora inganda nizindi nganda.Muri rusange, ubuziranenge bwa gaze yo kubungabunga ni 99,99%, kandi bimwe bisaba azote irenga 99,998%.
Amashanyarazi ya azote ni isoko ikonje ikonje, ikoreshwa cyane mububiko bw'amasohoro mu nganda y'ibiribwa, akazi n'ubworozi.Mu gukora ammonia yubukorikori mu nganda zifumbire mvaruganda, hydrogène ya azote ivanze muri gaz ya sintetike ya ammoniya yogejwe kandi inonosorwa na azote yuzuye.Ibiri muri gaze ya inert birashobora kuba bike cyane, kandi ibirimo monoxide ya karubone na ogisijeni ntibishobora kurenga 20ppm.
Itandukanyirizo ryimyuka itandukanya ihame ryinjira, ni ukuvuga igipimo cyo gukwirakwiza ogisijeni na azote muri polymer idasanzwe.Iyo ogisijeni na azote byamamajwe hejuru ya polymer membrane, bitewe na gradient yibitekerezo kumpande zombi, gaze iratandukana ikanyura muri membrane, hanyuma ikamanuka kurundi ruhande rwa membrane.Kuberako ingano ya molekile ya ogisijeni iri munsi ya molekile ya azote, igipimo cyo gukwirakwiza ogisijeni muri polymer membrane ni kinini kuruta molekile ya azote.Muri ubu buryo, iyo umwuka winjiye muruhande rumwe rwa membrane, umwuka ukungahaye kuri ogisijeni urashobora kuboneka kurundi ruhande na azote irashobora kuboneka kuruhande rumwe.
Umwuka ukungahaye kuri azote na ogisijeni urashobora kuboneka ubudahwema gutandukanya umwuka nuburyo bwa membrane.Kugeza ubu, coefficente yo guhitamo polymer membrane yo gutandukanya ogisijeni na azote ni nka 3.5 gusa, kandi coefficente ya permeability nayo ni nto cyane.Ubwinshi bwa azote yibicuruzwa byatandukanijwe ni 95 ~ 99%, naho umwuka wa ogisijeni ni 30 ~ 40% gusa.Gutandukanya umwuka mubisanzwe bikorwa mubushyuhe bwicyumba, 0.1 ~ 0.5 × 106pa。
