Ntchito yoyamba yaku China yosungira kaboni kunyanja ikupita patsogolo kwambiri, yopitilira ma kiyubiki mita 100 miliyoni

Pa Seputembara 10, China National Offshore Oil Corporation (CNOOC) idalengeza kuti kuchuluka kosungirako mpweya woipa wa Enping 15-1 pulojekiti yosungiramo mafuta m'malo osungiramo mafuta a Enping 15-1 ku China koyamba kosungirako CO₂ ku China komwe kuli ku Pearl River Mouth Basin - kwadutsa ma kiyubiki mita 100 miliyoni. Kupambana kumeneku kuli kofanana ndi kuchepetsa kutulutsa mpweya wa kaboni pobzala mitengo 2.2 miliyoni, zomwe zikuwonetsa kukhwima kwaukadaulo waku China wosungira mpweya woipa wa carbon dioxide, zida, ndi luso laukainjiniya. Ndilofunika kwambiri pakupititsa patsogolo kukwaniritsidwa kwa zolinga za dziko la "dual carbon" ndikulimbikitsa kusintha kobiriwira, mpweya wochepa wa carbon ndi kusintha kwa chikhalidwe cha anthu.

Monga malo oyamba opangira mafuta a carbon dioxide kum'mawa kwa South China Sea, malo opangira mafuta a Enping 15-1, ngati atapangidwa pogwiritsa ntchito njira zanthawi zonse, amatulutsa mpweya woipa komanso mafuta osapsa. Izi sizingawononge malo a nsanja zam'mphepete mwa nyanja ndi mapaipi apansi pa nyanja komanso kuonjezera mpweya wa carbon dioxide, kutsutsana ndi mfundo za chitukuko chobiriwira.

Pambuyo pazaka zinayi za kafukufuku, CNOOC yachita upainiya wotumiza pulojekiti yoyamba yaku China ya CCS (Carbon Capture and Storage) pamalo opangira mafutawa, ndikusungira CO₂ matani opitilira 100,000 pachaka. Mu Meyi chaka chino, pulojekiti yoyamba yaku China ya CCUS (Carbon Capture, Utilization and Storage) idakhazikitsidwa papulatifomu ya malo omwewo mafuta, ndikukwaniritsa kukweza kwakukulu kwa zida, ukadaulo, ndi uinjiniya wa CCUS wakunyanja. Pogwiritsa ntchito njira zamakono kuti apititse patsogolo kupanga mafuta osakanizika komanso kuphatikizira CO₂, polojekitiyi yakhazikitsa njira yatsopano yobwezeretsanso mphamvu zam'madzi zomwe zimadziwika ndi "kugwiritsa ntchito CO₂ kuyendetsa kutulutsa mafuta ndikusunga mpweya kudzera mukupanga mafuta." Pazaka khumi zikubwerazi, malo opangira mafuta akuyembekezeka kubaya matani opitilira miliyoni miliyoni a CO₂, kukulitsa kupanga mafuta osakhazikika ndi matani 200,000.

Xu Xiaohu, Wachiwiri kwa General Manager wa Enping Operations Company yomwe ili pansi pa CNOOC Nthambi ya Shenzhen, adati: "Chiyambireni ntchito yake, ntchitoyi yakhala ikugwira ntchito mosatetezeka kwa maola opitilira 15,000, ndi jakisoni wochuluka wa CO₂ tsiku lililonse wokwana ma kiyubiki metres 210,000. Kugwiritsa ntchito mpweya wochepa wa minda yamafuta ndi gasi ku China kukuyenda bwino kwambiri pakuyesetsa kwa China kukwaniritsa zolinga zake zamphamvu za carbon ndi kusalowerera ndale.

CNOOC ikutsogolera mwachangu zomwe zikuchitika pakukula kwa CCUS m'mphepete mwa nyanja, ndikuyendetsa kusinthika kwake kuchokera kumapulojekiti owonetsera oyimilira kupita kukukula kophatikizana. Kampaniyo yakhazikitsa pulojekiti yoyamba ya China yolanda mpweya wa matani mamiliyoni khumi ndi kusungirako ku Huizhou, Guangdong, yomwe idzagwire ndendende mpweya wa carbon dioxide kuchokera kumabizinesi a m'dera la Daya Bay ndikuutengera ku Pearl River Mouth Basin. Ntchitoyi ikufuna kukhazikitsa mndandanda wamakampani am'mphepete mwa nyanja a CCUS.

Nthawi yomweyo, CNOOC ikugwiritsa ntchito mphamvu za carbon dioxide pakupititsa patsogolo kuchira kwa mafuta ndi gasi. Mapulani ali mkati okhazikitsa malo obwezeretsa mafuta kumpoto kwa CO₂ omwe ali pamalo opangira mpweya wa Bozhong 19-6, komanso malo obwezeretsanso gasi kum'mwera kwa CO₂ omwe amathandizira gawo la gasi lachilengedwe la triliyoni ma kiyubiki mita ku South China Sea.

Wu Yiming, Woyang'anira dipatimenti ya Production ku CNOOC Nthambi ya Shenzhen, adati: "Kukula kosasunthika kwaukadaulo wa CCUS kudzapereka chithandizo chaukadaulo ku China kuti ikwaniritse zolinga zake za 'carbon wapawiri', kutsogolera kusintha kwamakampani opanga magetsi kukhala obiriwira, otsika mpweya, komanso chitukuko chokhazikika, ndikuthandizira mayankho ndi mphamvu zaku China pakuwongolera nyengo padziko lonse lapansi.

SJPEE idadzipereka kupanga zida zosiyanasiyana zolekanitsa ndi zida zosefera zamafakitale amafuta, gasi, ndi petrochemical, monga ma hydrocyclone amafuta/madzi, ma hydrocyclone ochotsa mchenga a tinthu tating'onoting'ono tating'onoting'ono, mayunitsi oyandama, ndi zina zambiri. Tadzipereka kupereka zida zolekanitsa komanso zokwera kwambiri, komanso zosintha za gulu lachitatu ndi ntchito zogulitsa pambuyo pake. Pokhala ndi ma patent angapo odziyimira pawokha, kampaniyo imatsimikiziridwa pansi pa DNV/GL-recognized ISO 9001, ISO 14001, ndi ISO 45001 Quality Management and Production Services Systems.

Zogulitsa za SJPEE zakhala zikugwiritsidwa ntchito kwambiri pamapulatifomu a Wellhead ndi nsanja zopangira mafuta ndi gasi monga CNOOC, PetroChina, Petronas Malaysia, Indonesia, ndi Gulf of Thailand. Ndi katundu wotumizidwa ku mayiko ambiri, atsimikizira kukhala odalirika kwambiri.
