Iyunithi Yokuhlukaniswa Komoya(ASU) Isithombe Esifakiwe

I-Air Seperation Unit(ASU)

Incazelo emfushane:

Iyunithi yokuhlukaniswa komoya iwuhlobo lwemishini ethatha umoya njengento eluhlaza, iwuguqule ube yisimo esiwuketshezi ngokuyicindezela futhi iphole emazingeni okushisa e-cryogenic, bese ihlukanisa kancane kancane umoya-mpilo, i-nitrogen, i-argon noma eminye imikhiqizo yoketshezi emoyeni owuketshezi ngokulungiswa. .Ngokwezidingo zabasebenzisi, imikhiqizo yamayunithi okuhlukanisa umoya ingaba imikhiqizo eyodwa noma imikhiqizo eminingi ngesikhathi esisodwa, okungaba igesi noma uketshezi.

Incazelo Yomkhiqizo

Iyunithi yokuhlukaniswa komoya iwuhlobo lwemishini ethatha umoya njengento eluhlaza, iwuguqule ube yisimo esiwuketshezi ngokuyicindezela futhi iphole emazingeni okushisa e-cryogenic, bese ihlukanisa kancane kancane umoya-mpilo, i-nitrogen, i-argon noma eminye imikhiqizo yoketshezi emoyeni owuketshezi ngokulungiswa. .Ngokwezidingo zabasebenzisi, imikhiqizo yamayunithi okuhlukanisa umoya ingaba yimikhiqizo eyodwa noma eminingi ngesikhathi esisodwa, okungaba igesi noma uketshezi.

Inqubo ethile (ukucindezela kwangaphandle) yile: umoya ocindezelwe ovela ku-compressor yomoya, ngemva kokukhipha ukungcola okunjengomswakama, i-carbon dioxide, ama-hydrocarbons nokunye ukungcola nge-sieve yamangqamuzana, uthunyelwa ngokuqondile kukholamu engenhla ye-distillation, kanti enye ingxenye ingena. isandisi.Ngemva kokunwetshwa, umoya we-cryogenic uthunyelwa kukholomu engezansi.Ngokulungisa, i-nitrogen ingatholakala phezulu kwekholomu engenhla kanye ne-oxygen ngaphansi kwekholomu engenhla.I-oxygen ehlukanisiwe, i-nitrogen namagesi e-exhaust ashiswa kabusha isishintshi sokushisa esiyinhloko bese ekhishwa ebhokisini elibandayo.I-oxygen noma imikhiqizo ye-nitrogen ephuma ebhokisini elibandayo icindezelwa ama-compressor kungcindezi eshiwo futhi ithunyelwe kumsebenzisi.

Izinzuzo

1. Isofthiwe yokubala yokusebenza ethuthukisiwe evela phesheya isetshenziselwa ukuthuthukisa nokuhlaziya inqubo yalesi sixhobo ukuqinisekisa ukuthi sinezinkomba ezingcono kakhulu zobuchwepheshe nezomnotho kanye nesilinganiso esihle kakhulu samanani okusebenza.

2.Iyunithi yokuhlukanisa umoya (umkhiqizo oyinhloko O₂) yamukela i-evaporator esebenza kahle kakhulu yokujiya enokugeleza okuphoqelekile kokungena koketshezi engxenyeni engezansi yoketshezi lomoya, okuvumela umoya ocebeswe umoya-mpilo ukuba uhwamuke futhi ugeleze usuka phansi uye phezulu ku-evaporator yokufingqa, ukugwema ukunqwabelana kwe-hydrocarbon.

3. Ukuqinisekisa ukuphepha nokuthembeka kwemishini, yonke imikhumbi yokucindezela, amapayipi okucindezela kanye nezingxenye zokucindezela ku-ASU zenzelwe ngokuqinile, zenziwe futhi zihlolwe ngokuhambisana nemithetho kazwelonke efanele.Ibhokisi elibandayo le-ASU kanye namapayipi ebhokisini elibandayo kudlule isibalo samandla.

Ezinye Izinzuzo

Iningi lonjiniyela eqenjini lezobuchwepheshe lenkampani lenze inqwaba yemiklamo ye-ASU ye-cryogenic yezinkampani zegesi zamazwe ngamazwe kanye nezinkampani zegesi zasekhaya.

Ngolwazi olubanzi ekwakhiweni kwe-ASU kanye nokwenziwa kwephrojekthi, singanikela ngamajeneretha e-nitrogen (300 Nm³/h–60,000 Nm³/h), ama-ASU amancane (1000 Nm³/h–10,000 Nm³/h), nama-ASU amakhulu (20,000 Nm3/h–60,000 Nm³/h).
