Njira yolekanitsa mpweya ili motere: Mu ASU, mpweya umakokedwa koyamba ndipo umadutsa muzosefera zingapo, kuponderezana, kuziziritsa, komanso kuyeretsa. Njira zoziziritsa komanso zoyeretsa zimatulutsa chinyezi, mpweya woipa, ndi ma hydrocarbon. Mpweya wothandizidwawo umagawidwa pawiri. Gawo limodzi limalowa m'munsi mwa mizati yamagulu pambuyo pa kusinthanitsa kutentha ndi mankhwala okosijeni ndi nayitrogeni ikuchitika, pamene gawo lina limadutsa muzitsulo zazikulu zotentha kutentha ndi kukulitsa dongosolo musanalowe mzati wolekanitsa mpweya. Mu kagawo kakang'ono, mpweya umagawidwanso kukhala oxygen ndi nitrogen.
• Mapulogalamu apamwamba owerengera omwe amatumizidwa kuchokera kumayiko ena amagwiritsidwa ntchito kukhathamiritsa kusanthula kwa zida, kuwonetsetsa kuti luso lapamwamba laukadaulo ndi zachuma komanso magwiridwe antchito abwino kwambiri.
•Chigawo chakumtunda kwa ASU (chinthu chachikulu O₂) chimagwiritsa ntchito evaporator yothamanga kwambiri, kukakamiza mpweya wamadzimadzi kuti usasunthike kuchokera pansi kupita pamwamba kuti apewe kudzikundikira kwa hydrocarbon ndikuwonetsetsa chitetezo chadongosolo.
• Kuonetsetsa chitetezo cha zida ndi kudalirika, zombo zonse zoponderezedwa, mapaipi, ndi zida zokakamiza mu ASU zidapangidwa, zopangidwa, ndikuyesedwa motsatira malamulo adziko. Bokosi lozizira lolekanitsa mpweya ndi mapaipi omwe ali mkati mwa bokosi lozizira amapangidwa ndi mawerengedwe amphamvu.
•Mainjiniya ambiri amakampani athu amachokera kumakampani apadziko lonse lapansi komanso apanyumba, omwe ali ndi chidziwitso chambiri pakupanga makina olekanitsa mpweya wa cryogenic.
•Pokhala ndi chidziwitso chambiri pakupanga ndi kukhazikitsidwa kwa projekiti ya ASU, titha kupereka majenereta a nayitrogeni (300 Nm³/h - 60,000 Nm³/h), magawo ang'onoang'ono olekanitsa mpweya (1,000 Nm³/h - 10,000 Nm³/h), komanso magawo olekanitsa apakati mpaka akulu. (10,000 Nm³/h - 60,000 Nm³/h).
