Thaum Lub Yim Hli 16, qhov project rov qab siv roj ethane ntawm Tarim Oilfield, uas yog ib qhov project tseem ceeb ntawm PetroChina, tau ua tiav thiab muab tso rau hauv kev ua haujlwm, thiab cov khoom ethane tsim nyog tau tsim tawm. Muaj kev tshaj tawm tias qhov project no yog thawj qhov project rov qab siv roj ethane uas tau muab tso rau hauv kev ua haujlwm hauv Xinjiang.
Qhov project Tarim Oilfield natural gas ethane recovery nyob hauv Lunnan Industrial Park, Luntai County, Bazhou, Xinjiang, npog thaj tsam ntawm 320 mu nrog tag nrho cov peev txheej ntawm 1.62 billion yuan. Kev vam khom rau cov peev txheej natural gas nplua nuj hauv Tarim, qhov project siv cov txheej txheem thev naus laus zis "propane precooling + expansion refrigeration + double reflux" uas tau tsim kho thoob ntiaj teb thiab hauv tebchaws los ua 10 billion cubic meters ntawm natural gas ib xyoos. Nws yog ib qho ntawm cov chav kho ethane loj tshaj plaws hauv ib kab hauv Suav teb. Tom qab yuav luag ib hlis ntawm kev ua haujlwm, chav tsev tau dhau qhov kev ntsuam xyuas kev ua tau zoo, ua tiav txog tus qauv thiab peev xwm, thiab txhua qhov kev ntsuas thiab cov ntsuas tau ua raws li cov qauv tsim.
Ethane yog ib qho khoom siv tseem ceeb rau kev tsim cov ethylene, thiab ethylene yog ib qho ntawm cov khoom siv tshuaj lom neeg loj tshaj plaws hauv ntiaj teb. Kev lag luam Ethylene yog lub hauv paus ntawm kev lag luam petrochemical thiab ua lub luag haujlwm tseem ceeb hauv kev lag luam hauv tebchaws. Qhov project rov qab tau cov roj av ethane ntawm Tarim Oilfield yog ib qhov project nom tswv rau PetroChina los siv tog txoj kev tswj hwm Xinjiang hauv lub sijhawm tshiab thiab lub siab ntawm cov rooj sib tham ua haujlwm hauv nruab nrab Xinjiang yav dhau los thiab txhawb kev pabcuam kev lag luam rau Xinjiang. Nws tseem yog ib qhov project pab tau rau PetroChina los txhim kho qhov zoo thiab kev ua haujlwm zoo, ib qhov project tshiab los ua kom muaj kev vam khom rau kev tshawb fawb thiab thev naus laus zis, thiab nws tseem yog ib qhov project tshiab rau kev tsim khoom ruaj khov thiab kev tsim khoom ntawm Tarim Oilfield Cov haujlwm tseem ceeb los txhawb kev tsim cov chaw roj thiab roj loj niaj hnub hauv ntiaj teb.
Qhov project rov qab siv ethane tau pib thaum Lub Peb Hlis 14, 2020, thiab xa tag nrho thaum Lub Tsib Hlis 28, 2021, kev siv roj tau pib ua haujlwm thaum Lub Xya Hli 16, lub tshuab nthuav dav tau pib ua haujlwm thaum Lub Xya Hli 20, thiab cov khoom ethane tsim nyog tau tsim tawm thaum Lub Xya Hli 23, ua ntej 8 hnub ntawm txoj kev npaj thawj zaug. Thaum lub sijhawm tsim kho, qhov project tau ntsib ob qhov teeb meem. Vim muaj teeb meem xws li kev thauj khoom tsawg, kev khiav haujlwm nyuaj thiab kev tsim kho nyuaj thaum lub caij ntuj no, Tarim Oilfield tau ua kom muaj kev sib xyaw ua ke ntawm kev tsim cov roj hydrocarbon sib dua thiab kev tsim kho project nrog kev mob siab rau thiab lub luag haujlwm siab. Hauv tag nrho cov txheej txheem tsim kho, kev nyab xeeb thiab kev tiv thaiv ib puag ncig tau tswj hwm thiab cov hom phiaj xav tau tau ua tiav.
Muaj kev tshaj tawm tias qhov kev ua tiav thiab kev ua haujlwm ntawm qhov project tuaj yeem ua tiav kev kho txhua xyoo ntawm 10 billion cubic meters ntawm cov roj av, nrog rau kev tsim tawm txhua xyoo ntawm 762000 tons ntawm ethane, 366000 tons ntawm cov roj liquefied thiab 75000 tons ntawm cov roj hydrocarbons ruaj khov. Tib lub sijhawm, qhov kev ua tiav thiab kev ua haujlwm ntawm qhov project tau tawg los ntawm "caj dab" kev txwv ntawm cov khoom siv raw ethane thiab cov thev naus laus zis ntau lawm, muab cov khoom siv raw ethane txaus thiab ruaj khov rau Dushanzi petrochemical, thiab muab kev lav zoo rau kev txhim kho ntawm cov saw hlau kev lag luam ntawm PetroChina cov tuam txhab hauv Xinjiang.
