Iyunithi yokuhlukanisa umoya (ASU)iyisizinda sezimboni esibalulekile esidlala indima ebalulekile ekukhishweni kwezingxenye ezinkulu zomkhathi, okuyi-nitrogen, umoya-mpilo, ne-argon. Inhloso yeyunithi yokuhlukanisa umoya iwukuhlukanisa lezi zingxenye emoyeni, okuvumela ukusetshenziswa kwazo ezinqubweni ezihlukahlukene zezimboni kanye nezicelo.
Inqubo yokuhlukaniswa komoya ibalulekile ezinhlobonhlobo zezimboni, okuhlanganisa ukukhiqiza amakhemikhali, ukunakekelwa kwezempilo, kanye ne-electronics. Izingxenye ezintathu eziyinhloko zomkhathi - i-nitrogen, umoya-mpilo, ne-argon - zonke zibalulekile ngokwazo futhi zisebenza ngezindlela ezihlukahlukene. I-nitrogen ivame ukusetshenziswa ekukhiqizeni i-ammonia kumanyolo, kanye nasembonini yokudla neziphuzo ukuze kuhlanganiswe futhi kugcinwe. I-oksijeni ibalulekile ngezinjongo zezokwelapha, ukusika insimbi, nokushisela, kuyilapho i-argon isetshenziselwa ukushisela kanye nokwakhiwa kwensimbi, kanye nokukhiqizwa kwezingxenye ze-elekthronikhi.
Inqubo yokuhlukanisa umoya ihilela ukusetshenziswa kwamasu ahlukahlukene afana ne-cryogenic distillation, i-pressure swing adsorption, nokuhlukaniswa kwe-membrane ukuze kuhlukaniswe izingxenye zomoya ngokusekelwe kumaphuzu azo abilayo kanye nosayizi wamangqamuzana. I-Cryogenic distillation iyindlela evamile kakhulu esetshenziswa ezindaweni ezinkulu zokuhlukanisa umoya, lapho umoya upholiswa khona futhi ufakwe uketshezi ngaphambi kokuba uhlukaniswe izingxenye zawo.
Amayunithi okuhlukanisa umoyazenzelwe ukukhiqiza i-nitrogen, i-oxygen, ne-argon ehlanzekile kakhulu, bese ifakwa uketshezi noma icindezelwe ukuze igcinwe futhi isatshalaliswe. Ikhono lokukhipha lezi zingxenye emkhathini ngezinga lezimboni libalulekile ukuze kuhlangatshezwane nezidingo zezimboni ezihlukahlukene kanye nokuqinisekisa ukutholakala okuthembekile kwala magesi.
Kafushane, inhloso yeyunithi yokuhlukanisa umoya ukukhipha izingxenye ezinkulu zomkhathi - i-nitrogen, umoya-mpilo, ne-argon - ukuze zisetshenziswe ezinhlobonhlobo zezinhlelo zokusebenza zezimboni. Ngokusebenzisa amasu okuhlukanisa athuthukile, amayunithi okuhlukanisa komoya adlala indima ebalulekile ekuhlinzekeni amagesi ahlanzekile abalulekile ezinqubweni eziningi zemboni kanye nemikhiqizo.
