IYunithi yoKwahlulwa koMoya (ASU) Umfanekiso obonakalisiweyo

IYunithi yoKwahlula uMoya (ASU)

Inkcazelo emfutshane:

Iyunithi yokwahlula umoya luhlobo lwezixhobo ezithatha umoya njengento ekrwada, ijike ibe yimeko yolwelo ngokuyicinezela kwaye ipholise kumaqondo obushushu e-cryogenic, kwaye ngokuthe ngcembe yahlula ioksijini, initrogen, i-argon okanye ezinye iimveliso ezingamanzi ukusuka kulwelo lomoya ngokulungiswa. .Ngokweemfuno zabasebenzisi, iimveliso zeeyunithi zokwahlula umoya zinokuba yimveliso enye okanye iimveliso ezininzi ngaxeshanye, ezinokuba yigesi okanye ulwelo.

Ingcaciso yeMveliso

Iyunithi yokwahlula umoya luhlobo lwezixhobo ezithatha umoya njengento ekrwada, ijike ibe yimeko yolwelo ngokuyicinezela kwaye ipholise kumaqondo obushushu e-cryogenic, kwaye ngokuthe ngcembe yahlula ioksijini, initrogen, i-argon okanye ezinye iimveliso ezingamanzi ukusuka kulwelo lomoya ngokulungiswa. .Ngokweemfuno zabasebenzisi, iimveliso zeeyunithi zokwahlula umoya zingaba yinye okanye iimveliso ezininzi ngaxeshanye, ezinokuba yigesi okanye ulwelo.

Inkqubo ethile (uxinzelelo lwangaphandle) kukuba: umoya ocinezelweyo ovela kwi-compressor yomoya, emva kokususa ukungcola okunjengomswakama, i-carbon dioxide, i-hydrocarbons kunye nezinye izinto ezingcolileyo nge-sieve ye-molecular, ithunyelwa ngokuthe ngqo kwikholamu ye-distillation ephezulu, kwaye enye inxalenye ingena. isandisi.Emva kokwandiswa, umoya we-cryogenic uthunyelwa kwikholamu engezantsi.Ngokulungiswa, i-nitrogen inokufumaneka phezulu kwikholomu ephezulu kunye ne-oksijini ephantsi kwekholamu ephezulu.I-oksijeni eyahlukileyo, i-nitrogen kunye ne-exhaust gases iphinda ifudunyezwe ngumqhubi omkhulu wokushisa kwaye ikhutshwe kwibhokisi ebandayo.Ioksijini okanye iimveliso ze-nitrogen eziphuma kwibhokisi ebandayo zinyanzeliswa yi-compressors kuxinzelelo oluchaziweyo kwaye zithunyelwe kumsebenzisi.

Iingenelo

1. Isoftware yokubala intsebenzo ekwinqanaba eliphezulu ethunyelwa kumazwe angaphandle isetyenziselwa ukukhulisa nokuhlalutya inkqubo yesi sixhobo ukuqinisekisa ukuba inezona zalathisi zobugcisa nezoqoqosho zibalaseleyo kunye nomlinganiselo ogqwesileyo wexabiso lentsebenzo.

2.Iyunithi yokwahlula umoya (imveliso ephambili O₂) ithatha i-evaporator ye-condensation ephezulu esebenzayo kunye nokuhamba okunyanzeliswayo kwe-inlet yolwelo kwindawo esezantsi yolwelo lomoya, evumela umoya ophuculweyo we-oksijini ukuba uphoqeke ube ngumphunga kwaye uhambe ukusuka ezantsi ukuya phezulu kwi-evaporator ye-condensation, ukuphepha ukuqokelelwa kwe-hydrocarbon.

3. Ukuqinisekisa ukhuseleko kunye nokuthembeka kwezixhobo, zonke iinqanawa zoxinzelelo, iipayipi zoxinzelelo kunye namacandelo oxinzelelo kwi-ASU zenziwe ngokungqongqo, zenziwe kwaye zihlolwe ngokuhambelana nemimiselo kazwelonke efanelekileyo.Ibhokisi ebandayo ye-ASU kunye nombhobho kwibhokisi ebandayo idlulile ukubala amandla.

Ezinye Iingenelo

Uninzi lweenjineli kwiqela lobuchwephesha benkampani lenze inani elikhulu loyilo lwe-ASU ye-cryogenic kwiinkampani zerhasi zamazwe ngamazwe kunye neenkampani zegesi zasekhaya.

Ngamava abanzi kuyilo lwe-ASU kunye nokwenziwa kweprojekthi, sinokubonelela ngeejenereyitha zenitrogen (300 Nm³/h–60,000 Nm³/ h), ii-ASU ezincinci (1000 Nm³/h–10,000 Nm³/h), kunye nee-ASUs ezinkulu (20,000 Nm3/h–60,000 Nm³/h).
