Mhla ziyi-16 kuNcwaba, iphrojekthi yokubuyisela igesi yemvelo ye-ethane ye-Tarim Oilfield, iphrojekthi ebalulekile yePetroChina, yaqedwa ngempumelelo futhi yaqala ukusebenza, futhi kwakhiqizwa imikhiqizo efanelekile ye-ethane. Kubikwa ukuthi le phrojekthi iphrojekthi yokuqala yokubuyisela i-ethane eqale ukusebenza ngempumelelo eXinjiang.
Iphrojekthi ye-Tarim Oilfield ye-natural gas ethane recovery project iseLunnan Industrial Park, Luntai County, Bazhou, Xinjiang, ihlanganisa indawo engu-320 mu ngesamba sokutshalwa kwezimali kwe-1.62 billion yuan. Ngokuthembela kumithombo yegesi yemvelo ecebile e-Tarim, le phrojekthi yamukela ubuchwepheshe benqubo ye-propane precooling + expansion refrigeration + double reflux ethuthukisiwe emhlabeni wonke futhi yasekhaya ukuze kucubungulwe i-cubic metres ye-10 billion yegesi yemvelo ngonyaka. Ingenye yamayunithi amakhulu kakhulu okubuyisela i-ethane emgqeni owodwa e-China. Ngemva cishe kwenyanga yokugunyazwa, iyunithi iphumelele ukuhlolwa kokusebenza, okufinyelelwe ezingeni kanye namandla, futhi yonke imingcele nezinkomba zihlangabezana nezidingo zokuklama.
I-Ethane iyinto ebalulekile yokukhiqiza i-ethylene, kanti i-ethylene ingenye yemikhiqizo yamakhemikhali emikhulu kakhulu emhlabeni. Imboni ye-ethylene iwumgogodla wemboni ye-petrochemical futhi idlala indima ebalulekile emnothweni kazwelonke. Iphrojekthi yokubuyisela igesi yemvelo ye-Tarim Oilfield iphrojekthi yezepolitiki yePetroChina ukuze isebenzise isu leqembu lokuphatha i-Xinjiang enkathini entsha nomoya wezingqungquthela zangaphambilini ze-Xinjiang kanye nokukhuthaza usizo lwezimboni e-Xinjiang. Kuphinde kube iphrojekthi ezuzisayo yePetroChina yokuthuthukisa izinga nokusebenza kahle, iphrojekthi entsha yokuthola ukuzimela ngokwesayensi nobuchwepheshe, futhi iphrojekthi entsha yokukhiqiza nokukhiqiza okuzinzile kanye nokukhiqizwa kwamaphrojekthi Abalulekile we-Tarim Oilfield ukuze akhuthaze ngokuphelele ukwakhiwa komhlaba. -class izinkundla ezinkulu zesimanje zikawoyela negesi.
Iphrojekthi yokubuyiswa kwe-ethane yaqalwa ngoMashi 14, 2020, yethulwa isiyonke ngoMeyi 28, 2021, isingeniso segesi saqala ukusebenza ngoJulayi 16, i-expander yaqala ukusebenza ngoJulayi 20, kwakhiqizwa imikhiqizo efanelekile ye-ethane. ngoJulayi 23, izinsuku eziyi-8 ngaphambi kohlelo lwangempela. Phakathi nenqubo yokwakha, iphrojekthi ihlangabezane nokuqubuka kwezifo ezimbili. Ebhekene nezinkinga ezifana nokulinganiselwa kwezinto zokuhamba, ukuhamba kanzima kwabasebenzi kanye nokwakhiwa okunzima ebusika, i-Tarim Oilfield iye yaqinisekisa inhlanganisela efanele yokukhiqiza i-hydrocarbon ekhanyayo kanye nokwakhiwa kwephrojekthi ngomqondo ophezulu wokuzinikezela nomthwalo wemfanelo. Kuwo wonke umsebenzi wokwakha, ukuphepha nokuvikelwa kwemvelo kwalawulwa futhi izinjongo ezilindelekile zafezwa ngempumelelo.
Kubikwa ukuthi ukuphothulwa nokusebenza kwephrojekthi kungafinyelela ukwelashwa konyaka kwe-cubic metres yemvelo eyizigidi eziyizinkulungwane eziyi-10, ngokukhishwa konyaka okungamathani angama-762000 e-ethane, amathani angama-366000 egesi eliwuketshezi kanye namathani angama-75000 wama-hydrocarbon akhanyayo azinzile. Ngaso leso sikhathi, ukuphothulwa nokusebenza kwephrojekthi kwephule “intamo” yokuvinjelwa kwezinto zokusetshenziswa ze-ethane kanye nobuchwepheshe bokukhiqiza, kwahlinzeka ngezinto zokusetshenziswa ze-ethane ezanele nezizinzile ze-Dushanzi petrochemical, futhi kwanikeza isiqinisekiso esiqinile sokuthuthukiswa kochungechunge lwezimboni. yePetroChina amabhizinisi eXinjiang.
Isikhathi sokuthumela: Sep-09-2021
