Ngomhlaka-16 Agasti, iphrojekthi yokubuyisa i-ethane yegesi yemvelo yaseTarim Oilfield, iphrojekthi ebalulekile yePetroChina, yaqedwa ngempumelelo futhi yaqala ukusebenza, kwakhiqizwa imikhiqizo ye-ethane efanelekile. Kubikwa ukuthi le phrojekthi iwumsebenzi wokuqala wokubuyisa i-ethane owaqalwa ngempumelelo eXinjiang.
Iphrojekthi yokubuyisa i-ethane yegesi yemvelo iTarim Oilfield itholakala eLunnan Industrial Park, eLuntai County, eBazhou, eXinjiang, ehlanganisa indawo engama-mu angu-320 kanye nokutshalwa kwezimali okuphelele okungu-1.62 billion yuan. Ithembele emithonjeni yegesi yemvelo ecebile eTarim, le phrojekthi isebenzisa ubuchwepheshe benqubo obuphambili emhlabeni wonke kanye nobasekhaya obuhamba phambili “be-propane precooling + expansion refrigeration + double reflux” ukucubungula ama-cubic metres ayizigidi eziyi-10 zegesi yemvelo ngonyaka. Ingenye yamayunithi amakhulu okubuyisa i-ethane emgqeni owodwa eShayina. Ngemva cishe kwenyanga yokusebenza, le yunithi idlulile ekuhlolweni kokusebenza, yafinyelela ezingeni elijwayelekile kanye nomthamo, futhi wonke amapharamitha kanye nezinkomba ziyahlangabezana nezidingo zomklamo.
I-Ethane iyinto ebalulekile yokukhiqiza i-ethylene, kanti i-ethylene ingenye yemikhiqizo yamakhemikhali emikhulu emhlabeni. Imboni ye-ethylene iyisisekelo semboni yamakhemikhali kaphethroli futhi idlala indima ebalulekile emnothweni wezwe. Iphrojekthi yokubuyisa i-ethane yegesi yemvelo yeTarim Oilfield iphrojekthi yezepolitiki yePetroChina yokusebenzisa isu leqembu lokuphatha iXinjiang enkathini entsha kanye nomoya wezingqungquthela zomsebenzi ze-Xinjiang zangaphambilini kanye nokukhuthaza usizo lwezimboni eXinjiang. Futhi kuyiphrojekthi yenzuzo yePetroChina yokuthuthukisa ikhwalithi nokusebenza kahle, iphrojekthi entsha yokuqaphela ukuzimela kwesayensi nobuchwepheshe, futhi futhi iphrojekthi entsha yokukhiqizwa okuzinzile nokukhiqizwa kweTarim Oilfield Amaphrojekthi abalulekile okukhuthaza ngokuphelele ukwakhiwa kwamasimu amakhulu kawoyela negesi esimanje asezingeni lomhlaba.
Iphrojekthi yokubuyisa i-ethane yaqalwa ngoMashi 14, 2020, yalethwa iyonke ngoMeyi 28, 2021, ukwethulwa kwegesi kwaqala ukusebenza ngoJulayi 16, i-expander yaqala ukusebenza ngoJulayi 20, kanti imikhiqizo ye-ethane efanelekile yakhiqizwa ngoJulayi 23, izinsuku eziyi-8 ngaphambi kohlelo lokuqala. Ngesikhathi senqubo yokwakha, iphrojekthi ibhekane nokuqubuka okubili. Ibhekene nezinkinga ezifana nokuthuthwa kwezinto ezibonakalayo okulinganiselwe, ukuhamba kwabasebenzi okunzima kanye nokwakhiwa okunzima ebusika, i-Tarim Oilfield iqinisekise ukuhlanganiswa okufanele kokukhiqizwa kwe-hydrocarbon elula kanye nokwakhiwa kwephrojekthi ngomqondo omkhulu wokuzinikela kanye nomthwalo wemfanelo. Kuyo yonke inqubo yokwakha, ukuphepha nokuvikelwa kwemvelo kwalawulwa futhi izinhloso ezilindelwe zafezwa ngempumelelo.
Kubikwa ukuthi ukuqedwa nokusebenza kwale phrojekthi kungafeza ukwelashwa kwaminyaka yonke kwama-cubic metres ayizigidigidi eziyi-10 zegesi yemvelo, kanye nomkhiqizo waminyaka yonke wamathani angu-762000 e-ethane, amathani angu-366000 egesi encibilikisiwe kanye namathani angu-75000 ama-hydrocarbon akhanyayo azinzile. Ngesikhathi esifanayo, ukuqedwa nokusebenza kwale phrojekthi kwadlula ukuvinjelwa "kwentamo" kwezinto zokusetshenziswa ze-ethane kanye nobuchwepheshe bokukhiqiza, kwahlinzeka ngezinto zokusetshenziswa ze-ethane ezanele nezizinzile ze-petrochemical ye-Dushanzi, futhi kwanikeza isiqinisekiso esinamandla sokuthuthukiswa kochungechunge lwezimboni lwamabhizinisi e-PetroChina e-Xinjiang.
