Iiyunithi zokwahlula umoya(Ii-ASUs) zizixhobo ezibalulekileyo zezixhobo ezisetyenziswa kumashishini ahlukeneyo ukwahlula amacandelo omoya, ikakhulu initrogen kunye neoksijini, kwaye ngamanye amaxesha iargon kunye nezinye iigesi ezinqabileyo ezingenayo. Umgaqo wokwahlukana komoya usekelwe kwinto yokuba umoya ngumxube weegesi, kunye ne-nitrogen kunye ne-oksijini ibe ngamacandelo amabini aphambili. Eyona ndlela ixhaphakileyo yokwahlula komoya yi-fractional distillation, ethatha inzuzo yeeyantlukwano kwiindawo zokubilisa zamacandelo ukuze zihlukanise.
I-distillation ye-Fractional isebenza kumgaqo wokuba xa umxube weegesi upholile kwiqondo lokushisa eliphantsi kakhulu, amacandelo ahlukeneyo aya kudibanisa kumaqondo okushisa ahlukeneyo, ukuvumela ukuhlukana kwabo. Kwimeko yokwahlukana komoya, inkqubo iqala ngokucinezela umoya ongenayo kwiingcinezelo eziphezulu kwaye emva koko ipholise. Njengoko umoya uphola, ugqithiswa kuluhlu lweentsika zedistillation apho iinxalenye ezahlukeneyo zijiya kumaqondo obushushu ahlukeneyo. Oku kuvumela ukwahlukana kwenitrogen, ioksijini, kunye nezinye iigesi ezikhoyo emoyeni.
Inkqubo yokwahlula umoyaibandakanya amanyathelo angundoqo aliqela, kuquka ukucinezela, ukucocwa, ukupholisa, nokwahlula. Umoya ocinezelweyo uqala ngokucocwa ukuze ususe nabuphi na ukungcola nokufuma phambi kokuba upholiswe kumaqondo obushushu aphantsi kakhulu. Umoya opholileyo ugqithiswa kwiikholamu ze-distillation apho ukwahlukana kwamacandelo kwenzeka. Iimveliso eziphumayo ziqokelelwa kwaye zigcinwe kwizicelo ezahlukeneyo zamashishini.
Iiyunithi zokwahlula umoya zibalulekile kumashishini afana nemveliso yeekhemikhali, imveliso yentsimbi, ukhathalelo lwempilo, kunye ne-elektroniki, apho iigesi ezahluliweyo zisetyenziselwa uluhlu olubanzi lwezicelo. Ngokomzekelo, i-nitrojeni isetyenziswa kwishishini lokutya ukupakisha nokugcina, kwishishini le-elektroniki lokuvelisa i-semiconductors, nakwishishini le-oyile negesi yokufaka kunye nokugquma. Ioksijini, ngakolunye uhlangothi, isetyenziselwa ukusetyenziswa kwezonyango, ukusika isinyithi kunye ne-welding, kunye nokuveliswa kweekhemikhali kunye neglasi.
Ukuqukumbela, iiyunithi zokwahlula komoya zidlala indima ebalulekileyo kumashishini ahlukeneyo ngokwahlula amacandelo omoya kusetyenziswa umgaqo we-fractional distillation. Le nkqubo ivumela ukuveliswa kwenitrogen, ioksijini, kunye nezinye iigesi ezinqabileyo eziyimfuneko kuluhlu olubanzi lwezicelo zamashishini.
