Umushinga wo kugarura imyuka karemano ya Tarim Oilfield

Ku ya 16 Kanama, umushinga wo kugarura imyuka karemano ya Tarim Oilfield, umushinga w'ingenzi wa PetroChina, warangiye neza kandi utangira gukoreshwa, kandi hakorwa ibikoresho bya ethane byujuje ibisabwa. Bivugwa ko uyu mushinga ari wo wa mbere umushinga wo kugarura imyuka watangiye gukora neza muri Xinjiang.

Umushinga wo kugarura imvange ya ethane y’ingufu za Tarim Oilfield uherereye muri Pariki y’Indashyikirwa ya Lunnan, mu Karere ka Luntai, muri Bazhou, Xinjiang, ufite ubuso bwa mu 320 hamwe n’ishoramari rya miliyari 1.62 z’amayuan. Ushingiye ku mutungo kamere ukungahaye kuri gaze i Tarim, uyu mushinga ukoresha ikoranabuhanga ryateye imbere ku rwego mpuzamahanga no mu gihugu imbere mu gutunganya "propane precooling + expansion frigo + double reflux" kugira ngo utunganye metero kibe miliyari 10 za gaze ku mwaka. Ni imwe mu matsinda manini yo kugarura imvange ya ethane mu Bushinwa. Nyuma y’ukwezi hafi rukwezi itangiye gukora, iyi mashini yatsinze isuzuma ry’imikorere, igera ku rugero n’ubushobozi, kandi ibipimo byose n’ibipimo byujuje ibisabwa mu gishushanyo.

Ethane ni ingenzi mu gukora ethylene, kandi ethylene ni kimwe mu bicuruzwa binini bya chimique ku isi. Inganda za ethylene ni inkingi y'inganda za peteroli kandi zifite uruhare runini mu bukungu bw'igihugu. Umushinga wo kugarura ethane ya gaze karemano wa Tarim Oilfield ni umushinga wa politiki wa PetroChina wo gushyira mu bikorwa ingamba z'ishyaka ryo kuyobora Xinjiang mu gihe gishya n'umwuka w'inama z'akazi za Xinjiang zo hagati no guteza imbere inkunga y'inganda kuri Xinjiang. Ni umushinga kandi w'inyungu kuri PetroChina wo kunoza ireme n'imikorere myiza, umushinga uhanga wo kwiyubaka mu bya siyansi n'ikoranabuhanga, kandi ni umushinga uhanga wo gukora no gutunganya Tarim Oilfield mu buryo buhamye. Imishinga y'ingenzi yo guteza imbere byuzuye iyubakwa ry'ibibanza binini bya peteroli na gaze bigezweho ku isi.

Umushinga wo kugarura imvange watangiye ku ya 14 Werurwe 2020, utangwa wose ku ya 28 Gicurasi 2021, ishyirwaho rya gaze ritangira gukoreshwa ku ya 16 Nyakanga, imashini yo kongera ingufu itangira gukora ku ya 20 Nyakanga, naho ibikoresho bya ethane byujuje ibisabwa bikorwa ku ya 23 Nyakanga, iminsi 8 mbere y'uko umushinga utangira. Mu gihe cy'ubwubatsi, umushinga wahuye n'ibibazo bibiri nko gutwara ibikoresho bike, urujya n'uruza rw'abakozi rugoye ndetse n'ubwubatsi bugoye mu gihe cy'itumba, Tarim Oilfield yemeje ko habaho guhuza neza umusaruro w'amashanyarazi yoroheje n'ubwubatsi bw'umushinga, hifashishijwe ubwitange n'inshingano. Mu gihe cyose cy'ubwubatsi, umutekano no kurengera ibidukikije byaragenzuwe kandi intego zari zitezweho zagezweho neza.

Bivugwa ko kurangiza no gukoresha umushinga bishobora kugera ku isuku ya metero kibe miliyari 10 za gaze karemano buri mwaka, hamwe n’umusaruro wa toni 762000 za ethane, toni 366000 za gaze ishyushye na toni 75000 za hydrocarbons z’urumuri zihamye. Muri icyo gihe, kurangiza no gukoresha umushinga byaciye mu nzira yo kugabanya “ijosi” ibikoresho fatizo bya ethane n’ikoranabuhanga mu gukora, bitanga ibikoresho fatizo bya ethane bihagije kandi bihamye bya peteroli ya Dushanzi, kandi bitanga icyizere gikomeye cyo kuvugurura uruhererekane rw’inganda z’ibigo bya PetroChina muri Xinjiang.
