Chiyuniti chekuparadzanisa mhepo (ASU)inzvimbo yakakosha yemaindasitiri ine basa guru mukubvisa zvikamu zvikuru zvemhepo, zvinoti nitrogen, oxygen, uye argon. Chinangwa chechikamu chekuparadzanisa mhepo ndechekuparadzanisa zvikamu izvi kubva mumhepo, zvichibvumira kushandiswa mumabasa akasiyana-siyana emaindasitiri nekushandiswa.
Maitiro ekuparadzanisa mhepo akakosha kumaindasitiri akasiyana-siyana, anosanganisira kugadzira makemikari, hutano, uye zvemagetsi. Zvikamu zvitatu zvikuru zvemhepo - nitrogen, oxygen, uye argon - zvese zvinokosha uye zvine mashandisirwo akasiyana-siyana. Nitrogen inowanzo shandiswa mukugadzira ammonia yefetereza, pamwe chete nemuindasitiri yezvikafu nezvinwiwa pakurongedza nekuchengetedza. Okisijeni inokosha pakurapa, kucheka simbi, uye kusanganisa, nepo argon ichishandiswa mukusanganisa nekugadzira simbi, pamwe nekugadzira zvikamu zvemagetsi.
Maitiro ekuparadzanisa mhepo anosanganisira kushandiswa kwenzira dzakasiyana-siyana dzakadai se cryogenic distillation, pressure swing adsorption, uye membrane separation kuparadzanisa zvikamu zvemhepo zvichienderana nenzvimbo dzazvo dzekufashaira uye saizi yemamorekuru. Cryogenic distillation ndiyo nzira inonyanya kushandiswa mumayuniti makuru ekuparadzanisa mhepo, uko mhepo inotonhodzwa uye inonyungudutswa isati yaparadzaniswa kuita zvikamu zvayo.
Zvikamu zvekuparadzanisa mhepodzakagadzirirwa kugadzira nitrogen, oxygen, uye argon yakachena kwazvo, izvo zvinozonyungudutswa kana kumanikidzwa kuti zvichengetwe uye zvigoverwe. Kukwanisa kubvisa zvinhu izvi kubva mumhepo padanho remaindasitiri kwakakosha pakuzadzisa zvinodiwa nemaindasitiri akasiyana-siyana uye kuve nechokwadi chekuti magasi aya anowanikwa zvakavimbika.
Muchidimbu, chinangwa chechikamu chekuparadzanisa mhepo ndechekuburitsa zvikamu zvikuru zvemhepo - nitrogen, oxygen, uye argon - kuti zvishandiswe mumabasa akasiyana-siyana emaindasitiri. Nekushandisa nzira dzepamusoro dzekuparadzanisa, zvikamu zvekuparadzanisa mhepo zvinoita basa rakakosha mukupa magasi akachena zvakanyanya akakosha kune akawanda maindasitiri nezvigadzirwa.
