Ntchito yobwezeretsa mpweya wachilengedwe wa Tarim Oilfield

Pa Ogasiti 16, pulojekiti yobwezeretsa mpweya wachilengedwe ku Tarim Oilfield, pulojekiti yofunika kwambiri ya PetroChina, inamalizidwa bwino ndipo inayamba kugwira ntchito, ndipo zinthu zoyenera zopangidwa ndi ethane zinapangidwa. Zanenedwa kuti pulojekitiyi ndi yoyamba yobwezeretsa mpweya wa ethane yomwe inayamba kugwira ntchito bwino ku Xinjiang.

Ntchito yokonzanso mpweya wachilengedwe wa Tarim Oilfield ili ku Lunnan Industrial Park, Luntai County, Bazhou, Xinjiang, ndipo ili ndi malo okwana 320 mu ndi ndalama zokwana 1.62 biliyoni yuan. Potengera mafuta ambiri achilengedwe ku Tarim, ntchitoyi ikugwiritsa ntchito ukadaulo wapamwamba komanso wapakhomo wa "propane precooling + expansion refrigeration + double reflux" wotsogola padziko lonse lapansi komanso wakunyumba kuti ipange ma cubic metres 10 biliyoni a mpweya wachilengedwe pachaka. Ndi imodzi mwama unit akuluakulu okonzanso mpweya wachilengedwe mu mzere umodzi ku China. Patatha pafupifupi mwezi umodzi ikuyambitsidwa, unit yadutsa kuwunika kwa magwiridwe antchito, yafika pamlingo woyenera komanso mphamvu, ndipo magawo onse ndi ma index akukwaniritsa zofunikira pa kapangidwe.

Ethane ndi chinthu chofunikira kwambiri popanga ethylene, ndipo ethylene ndi chimodzi mwa zinthu zazikulu kwambiri padziko lonse lapansi. Makampani a ethylene ndiye maziko a mafakitale a petrochemical ndipo amachita gawo lofunika kwambiri pachuma cha dziko. Pulojekiti yobwezeretsa ethane ya gasi lachilengedwe ku Tarim Oilfield ndi pulojekiti yandale ya PetroChina yokhazikitsa njira ya chipani cholamulira Xinjiang munthawi yatsopano komanso mzimu wa misonkhano yam'mbuyomu ya Xinjiang ndikulimbikitsa thandizo la mafakitale ku Xinjiang. Ndi pulojekiti yopindulitsanso kwa PetroChina kuti ikonze bwino komanso moyenera, pulojekiti yatsopano yopezera kudzidalira kwasayansi ndi ukadaulo, komanso ndi pulojekiti yatsopano yopanga ndi kupanga Tarim Oilfield Mapulojekiti ofunikira kuti alimbikitse kwambiri kumanga minda yayikulu yamafuta ndi gasi yamakono padziko lonse lapansi.

Ntchito yokonzanso mpweya wa ethane inayamba pa Marichi 14, 2020, inaperekedwa yonse pa Meyi 28, 2021, kuyambitsa mpweya kunayamba kugwira ntchito pa Julayi 16, chowonjezera mpweya chinayamba kugwira ntchito pa Julayi 20, ndipo zinthu zoyenera za ethane zinapangidwa pa Julayi 23, masiku 8 asanafike dongosolo loyambirira. Panthawi yomanga, ntchitoyi yakumana ndi kuphulika kawiri. Poyang'anizana ndi mavuto monga mayendedwe ochepa a zinthu, kuyenda kovuta kwa ogwira ntchito komanso kumanga kovuta m'nyengo yozizira, Tarim Oilfield yatsimikiza kuti kupanga ma hydrocarbon ochepa komanso kumanga pulojekitiyi kwaphatikizidwa bwino ndi kudzipereka kwakukulu komanso udindo. Mu ntchito yonse yomanga, chitetezo ndi kuteteza chilengedwe zinayang'aniridwa ndipo zolinga zomwe zinkayembekezeredwa zinakwaniritsidwa bwino.

Zanenedwa kuti kutha ndi kugwira ntchito kwa pulojekitiyi kungapangitse kuti pakhale kukonzedwa kwa gasi wachilengedwe wokwana ma kiyubiki mita 10 biliyoni pachaka, ndi kutulutsa matani 762000 a ethane pachaka, matani 366000 a gasi wosungunuka ndi matani 75000 a ma hydrocarbons okhazikika. Nthawi yomweyo, kutha ndi kugwira ntchito kwa pulojekitiyi kunadutsa malire a "khosi" a zinthu zopangira ethane ndi ukadaulo wopanga, kunapereka zinthu zopangira ethane zokwanira komanso zokhazikika za Dushanzi petrochemical, ndipo kunapereka chitsimikizo champhamvu cha kukweza unyolo wa mafakitale a mabizinesi a PetroChina ku Xinjiang.
