Zvidyarwa zveokisijeni zvinonyanya kuburitsa okisijeni uchishandisa iyo cryogenic mhepo yekuparadzanisa nzira, iyo chaiyo maitiro ayo anotevera:
Air pretreatment: Mhepo inosefa kubvisa guruva netsvina, yobva yamanikidzwa necompressor.
Kutonhodza uye liquefaction: Mhepo yakamanikidzwa inotonhodzwa kusvika kune imwe mvura uchishandisa firiji unit.
Distillation separation: Muchikamu chedistillation, uchishandisa mutsauko wepoindi yekubikira pakati peokisijeni (inofashaira -183 dhigirii) nenitrogen (inofashaidza -196 degree), nitrogen inonyungudutswa uye inoparadzaniswa nekudziisa uye distillation, ichisiya kunyanya mvura yeokisijeni.
Kuunganidzwa kwechigadzirwa: Mushure memhepo, mweya weokisijeni unoburitsa yaunoda yakakwira-okisijeni yakachena, kazhinji nekuchena kunodarika 99.6%.
Iyi nzira inoshandisa shanduko yemuviri kuparadzanisa oxygen nenitrogen. Mishonga yacho inowanikwa munzvimbo dzakawanda uye isingadhure, zvichiita kuti ikwane kugadzirwa kwakakura-kwemaindasitiri. Pamusoro pezvo, kune dzimwe nzira dzekugadzira okisijeni senge mamolecular sieve adsorption uye mvura electrolysis, asi iyo cryogenic mhepo yekuparadzanisa nzira ndiyo yekutanga nzira inoshandiswa mumaindasitiri.
