Iphrojekthi yokuqala yaseShayina yokugcina ikhabhoni engasogwini ifinyelela inqubekelaphambili enkulu, edlula ama-cubic metres ayizigidi eziyi-100

NgoSepthemba 10, i-China National Offshore Oil Corporation (CNOOC) yamemezela ukuthi ivolumu yokugcinwa kwe-carbon dioxide ehlanganisiwe yephrojekthi yokugcina i-carbon ye-Enping 15-1 yendawo kawoyela—iphrojekthi yokuqala yaseChina yokubonisa ukugcinwa kwe-CO₂ engasogwini etholakala ePearl River Mouth Basin—idlule i-cubic metres eyizigidi eziyi-100. Le mpumelelo ilingana nokunciphisa ukukhishwa kwekhabhoni ngokutshala izihlahla eziyizigidi ezi-2.2, okuphawula ukuvuthwa kobuchwepheshe baseChina bokugcina isikhutha se-carbon dioxide phesheya kwezilwandle, izinto zokusebenza, namandla obunjiniyela. Kubaluleke kakhulu ukusheshisa ukufezekiswa kwezinjongo zezwe “zekhabhoni embaxambili” kanye nokugqugquzela uguquko oluluhlaza, olunekhabhoni ephansi kwezomnotho nezenhlalo.

Njengesizinda sikawoyela sokuqala esine-carbon dioxide ephezulu empumalanga ye-South China Sea, indawo kawoyela ye-Enping 15-1, uma ithuthukiswa kusetshenziswa izindlela ezijwayelekile, izokhiqiza i-carbon dioxide kanye nowoyela ongahluziwe. Lokhu ngeke nje kucekele phansi izikhungo zeplathifomu ezingasogwini namapayipi angaphansi kolwandle kodwa futhi kuzokwandisa ukukhishwa kwesikhutha, okungqubuzana nezimiso zokuthuthukiswa kokuluhlaza.

Ngemuva kweminyaka emine yocwaningo, i-CNOOC isungule uhlelo lokusatshalaliswa kwephrojekthi yaseChina yokuqala engasogwini i-CCS (Carbon Capture and Storage) kule ndawo kawoyela, enomthamo wokugcina we-CO₂ waminyaka yonke wamathani angaphezu kuka-100,000. NgoMeyi kulo nyaka, iphrojekthi yaseChina yokuqala engasogwini i-CCUS (I-Carbon Capture, Utilization and Storage) yethulwa endaweni yesikhulumi sesizinda sikawoyela esifanayo, yazuza ukuthuthukiswa okuphelele kwemishini, ubuchwepheshe, kanye nobunjiniyela be-CCUS yasogwini. Ngokusebenzisa izindlela zobuchwepheshe ukuze kuthuthukiswe ukukhiqizwa kukawoyela ongahluziwe kanye ne-sequester CO₂, iphrojekthi isisungule imodeli entsha yokuvuselela amandla olwandle ebonakala “ngokusebenzisa i-CO₂ ukushayela ukukhishwa kukawoyela nokubamba ikhabhoni ngokukhiqizwa kukawoyela.” Kule minyaka eyishumi ezayo, indawo kawoyela kulindeleke ukuthi ijove amathani angaphezu kwesigidi esisodwa se-CO₂, okukhuphule ukukhiqizwa kukawoyela ongahluziwe ngamathani angama-200,000.

UXu Xiaohu, iPhini Lomphathi Jikelele we-Enping Operations Company ngaphansi kwe-CNOOC Shenzhen Branch, uthe: “Selokhu yaqala ukusebenza ngokusemthethweni, le phrojekthi ibisebenza ngokuphepha amahora angaphezu kuka-15,000, inamandla omjovo wansuku zonke we-CO₂ wama-cubic metres angu-210,000. ukusetshenziswa kwekhabhoni ephansi kwezizinda zikawoyela negesi zasogwini zaseShayina limi njengempumelelo enkulu emizamweni yaseShayina yokufeza izinjongo zayo zokungathathi hlangothi kwekhabhoni.”

I-CNOOC ihola ngenkuthalo umkhuba ekuthuthukisweni kwe-CCUS yasogwini, iqhuba ukuvela kwayo kusuka kumaphrojekthi wokubonisa azimele kuya ekwandeni okuhlangene. Le nkampani yethule iphrojekthi yokuqala yaseShayina yokubamba kanye neqoqo lokulondolozwa kwekhabhoni eyizigidi eziyishumi e-Huizhou, e-Guangdong, ezobamba ngokunembile ukukhishwa kwe-carbon dioxide emabhizinisini asendaweni yase-Daya Bay futhi iwathuthe ayowugcina e-Pearl River Mouth Basin. Lolu hlelo luhlose ukusungula uchungechunge lwemboni ye-CCUS oluphelele noluqhudelana namazwe ngamazwe.

Ngasikhathi sinye, i-CNOOC isebenzisa ngokugcwele amandla abalulekile e-carbon dioxide ekwandiseni ukutholakala kukawoyela negesi. Kuyaqhubeka izinhlelo zokusungula isikhungo esisenyakatho esithuthukisiwe sokubuyisela uwoyela i-CO₂ esigxile endaweni yegesi i-Bozhong 19-6, kanye nesikhungo esiseningizimu ne-CO₂ esithuthukisiwe sokutholwa kwegesi esisebenzisa isifunda segesi yemvelo esiyi-trillion-cubic-metres oLwandle LwaseNingizimu China.

UWu Yiming, iMenenja yoMnyango Wezokukhiqiza e-CNOOC Shenzhen Branch, uthe: “Ukuthuthukiswa okuqhubekayo kobuchwepheshe be-CCUS kuzohlinzeka ngosizo lwezobuchwepheshe eChina ukuze ifinyelele izinjongo zayo ‘zekhabhoni embaxambili’, iqhubekisele phambili uguquko lwemboni yamandla ekuthuthukisweni okuluhlaza, okunekhabhoni ephansi, kanye nentuthuko esimeme, futhi kufake isandla ezisombululweni namandla eChina ekubuseni kwesimo sezulu emhlabeni jikelele.”

I-SJPEE izinikezele ekuthuthukiseni imishini ehlukene yokuhlukanisa ukukhiqiza kanye nemishini yokuhlunga yezimboni zikawoyela, igesi yemvelo, kanye ne-petrochemical, njengama-hydrocyclones kawoyela/amanzi, ama-hydrocyclone okususwa kwesihlabathi ezinhlayiya zezinga le-micron, amayunithi e-compact flotation, nokunye. Sizibophezele ekuhlinzekeni ngemishini esezingeni eliphezulu yokuhlukanisa kanye negibela eqhweni, kanye nezinguquko zemishini yezinkampani zangaphandle kanye nezinsiza zangemuva kokuthengisa. Ngamalungelo obunikazi amaningi obunikazi bendawo eqanjiwe, inkampani iqinisekiswa ngaphansi kwe-DNV/GL-recognized ISO 9001, ISO 14001, kanye ne-ISO 45001 yokuphathwa kwekhwalithi nezinhlelo zesevisi yokukhiqiza.

Imikhiqizo ye-SJPEE isetshenziswe kabanzi kumapulatifomu e-wellhead nasezinkundleni zokukhiqiza ezindaweni zikawoyela negesi ezifana ne-CNOOC, i-PetroChina, i-Petronas Malaysia, i-Indonesia, ne-Gulf of Thailand. Ngokuthunyelwa kwamanye amazwe emazweni amaningi, kuye kwabonakala kuthembekile kakhulu.
