Iyo yekuparadzanisa mweya unit (ASU)inzvimbo yakakosha yeindasitiri inoita basa rakakosha mukutorwa kwezvikamu zvikuru zvemumhepo, zvinoti nitrogen, oxygen, uye argon.Chinangwa chechikamu chekuparadzanisa kwemhepo ndechekuparadzanisa zvikamu izvi kubva kumhepo, zvichibvumira kushandiswa kwavo mune zvakasiyana-siyana zvemaindasitiri maitiro uye kushandiswa.
Iyo nzira yekuparadzaniswa kwemhepo yakakosha kune akasiyana maindasitiri, kusanganisira kugadzira makemikari, hutano, uye zvemagetsi.Zvinhu zvitatu zvikuru zvemuchadenga - nitrogen, oxygen, uye argon - zvese zvakakosha pachazvo uye zvine maapplication akasiyana.Nitrogen inowanzoshandiswa mukugadzirwa kweammonia yefetereza, pamwe neindasitiri yechikafu nechinwiwa yekurongedza nekuchengetedza.Okisijeni yakakosha kune zvinangwa zvekurapa, kutema simbi, uye kuputika, nepo argon inoshandiswa mukugadzira uye kugadzira simbi, pamwe nekugadzirwa kwezvinhu zvemagetsi.
Mhepo yekuparadzanisa maitiro inosanganisira kushandiswa kwemaitiro akasiyana-siyana akadai se cryogenic distillation, pressure swing adsorption, uye membrane kupatsanurwa kuparadzanisa zvikamu zvemhepo zvichibva pamapoinzi avo ekuvira uye saizi yemamorekuru.Cryogenic distillation ndiyo nzira inonyanya kushandiswa muzvikamu zvakakura zvekuparadzanisa mhepo, apo mweya unotonhodzwa uye unyoro usati waparadzaniswa muzvikamu zvayo.
Mhepo yekuparadzanisa zvikamudzakagadzirirwa kugadzira yakakwirira-kuchena nitrogen, okisijeni, uye argon, iyo inobva yanyungudutswa kana kumanikidzwa kuchengetedza uye kugovera.Kugona kuburitsa zvinhu izvi kubva mumhepo pachiyero cheindasitiri kwakakosha pakuzadzisa zvinodiwa nemaindasitiri akasiyana uye kuve nechokwadi chekupihwa kwakavimbika kwemagasi aya.
Muchidimbu, chinangwa chechikamu chekuparadzanisa mhepo ndechekutora zvikamu zvikuru zvemhepo - nitrogen, oksijeni, uye argon - kuti ishandiswe mumhando dzakasiyana-siyana dzekushandiswa kwemaindasitiri.Nekushandisa nzira dzepamberi dzekuparadzanisa, zvikamu zvekuparadzanisa mweya zvinoita basa rakakosha mukupa magasi akachena akakosha kune akawanda maindasitiri maitiro uye zvigadzirwa.
