Iyunithi yokwahlula umoya (ASU)liziko elibalulekileyo lemizi-mveliso elidlala indima ebalulekileyo ekutsalweni kwamacandelo amakhulu omoya, angala, initrogen, ioksijini, kunye neargon. Injongo yeyunithi yokwahlula umoya kukuhlula la macandelo emoyeni, ukuvumela ukuba zisetyenziswe kwiinkqubo ezahlukeneyo zoshishino kunye nokusetyenziswa.
Inkqubo yokwahlulwa komoya ibalulekile kuluhlu olubanzi lwamashishini, kubandakanywa ukwenziwa kweekhemikhali, ukhathalelo lwempilo, kunye nombane. Amacandelo amathathu aphambili omoya - initrogen, ioksijini, kunye neargon - zonke zixabisekile ngokwazo kwaye zinemisebenzi eyahlukeneyo. I-nitrogen idla ngokusetyenziswa ekuveliseni i-ammonia kwizichumisi, nakwishishini lokutya neziselo lokupakisha nokugcina. I-oksijeni ibalulekile kwiinjongo zonyango, ukusika isinyithi, kunye ne-welding, ngelixa i-argon isetyenziselwa i-welding kunye ne-metal fabrication, kunye nokuveliswa kwezinto ze-elektroniki.
Inkqubo yokwahlula komoya ibandakanya ukusetyenziswa kweendlela ezahlukeneyo ezifana ne-cryogenic distillation, i-adsorption swing pressure, kunye nokwahlulwa kwe-membrane ukwahlula amacandelo omoya ngokusekelwe kumanqaku abo abilayo kunye nobukhulu bemolekyuli. I-Cryogenic distillation yeyona ndlela ixhaphakileyo esetyenziswa kwiiyunithi ezinkulu zokwahlula umoya, apho umoya upholileyo kwaye unyibilike ngaphambi kokuba uhlukaniswe kumacandelo awo.
Iiyunithi zokwahlula umoyaziyilelwe ukuvelisa initrogen, ioksijini, kunye neargon ecocekileyo, ezithi ke zinyibilike okanye zicinezelwe ukuze zigcinwe kwaye zisasazwe. Ukukwazi ukukhupha la macandelo kwi-atmosfera kwinqanaba lemizi-mveliso kubalulekile ukuhlangabezana neemfuno zamashishini ahlukeneyo kunye nokuqinisekisa unikezelo oluthembekileyo lwezi gesi.
Isishwankathelo, injongo yeyunithi yokwahlukana komoya kukukhupha amacandelo amakhulu omoya - i-nitrogen, i-oksijini, kunye ne-argon - ukusetyenziswa kuluhlu olubanzi lwezicelo zoshishino. Ngokusebenzisa iindlela zokwahlula ezikumgangatho ophezulu, iiyunithi zokwahlula komoya zidlala indima ebalulekileyo ekuboneleleni ngeegesi ezicoceke kakhulu eziyimfuneko kwiinkqubo ezininzi zoshishino kunye neemveliso.
