amakhompi yokuqaphelela ukuze kuhlola i-Oxygen
Izitshalo zokuhlukanisa umoya-mpilo ngokumunca ziyisisombululo esiphambili kwezobuchwepheshe bokuhlukanisa igesi, zisebenzisa isimiso sokumunca umoya-mpilo (pressure swing adsorption - PSA) ukukhiqiza umoya-mpilo ohlanzekile emoyeni ozungezile. Lezi zinhlelo eziyinkimbinkimbi zisebenzisa izihlungi ezikhethekile zezinhlayiyana ezihlunga ngokukhetha ama-molecule e-nitrogen kuyilapho zivumela umoya-mpilo ukuba udlule, okuholela enqubo yokuhlukanisa esebenza kahle kakhulu. Lezi zitshalo zisebenza ngenqubo yokucindezela nokucindezela, lapho umoya ocindezelwe uphoqelelwa ukuba udlule emibhedeni yokumunca equkethe izinto zeolite. Phakathi nokusebenza, lezi zitshalo zigcina ukukhiqizwa komoya-mpilo okuqhubekayo ngokusebenzisa izitsha eziningi zokumunca ezisebenza ngemijikelezo eguquguqukayo, okuqinisekisa ukuphakelwa okungaphazanyiswa. Lobu buchwepheshe bungafinyelela emazingeni okuhlanzeka komoya-mpilo afinyelela kuma-95%, obenza bufaneleke ekusetshenzisweni kwezimboni ezihlukahlukene. Izitshalo zanamuhla zokuhlukanisa umoya-mpilo ngokuwufaka zifakwe izinhlelo zokulawula eziphambili ezilawula ngokuzenzakalelayo yonke inqubo yokuhlukanisa, kusukela ekucindezelweni komoya kuya ekuhanjisweni komoya-mpilo kokugcina. Lezi zitshalo zenzelwe ukwakheka okuhlukahlukene, okuvumela ukuthi kube lula ukukala amandla okukhiqiza ngokuya ngesidingo. Zihlanganisa nezinhlelo zokubuyisa amandla ezinciphisa kakhulu izindleko zokusebenza ngokusebenzisa kabusha umoya ocindezelweyo phakathi nemijikelezo yokucindezela.
