Ọrụ nchekwa ikuku carbon mbụ nke China nwetara nnukwu ọganihu, gafere 100 nde cubic mita

Na Septemba 10, China National Offshore Oil Corporation (CNOOC) kwupụtara na mkpokọta nchekwa carbon dioxide nke ọrụ nchekwa carbon carbon Enping 15-1 mmanụ — Oru ngo nchekwa CO₂ mbụ nke China nke dị na Pel River Mouth Basin — agafeela 100 nde cubic mita. Mmezu a dabara na ibelata ikuku carbon site n'ịkụ osisi nde 2.2, na-egosi ntozu oke teknụzụ nchekwa carbon dioxide nke China dị n'ụsọ osimiri, akụrụngwa, na ike injinia. Ọ na-ejide ihe dị mkpa maka ịgbasa mmezu nke ebumnuche "carbon abụọ" nke obodo na ịkwalite mgbanwe akụ na ụba na nke ọha mmadụ na-acha akwụkwọ ndụ akwụkwọ ndụ, obere carbon.

Dị ka ebe mbụ mmanụ carbon dioxide dị elu dị n'ebe ọwụwa anyanwụ South China Sea, Enping 15-1 mmanụ mmanụ ga-, ọ bụrụ na e mepụtara site na usoro omenala, na-emepụta carbon dioxide tinyere mmanụ crude. Ọ bụghị naanị na nke a ga-emebi akụrụngwa ikpo okwu nke dị n'akụkụ mmiri na pipeline dị n'okpuru mmiri kamakwa ọ ga-abawanye ikuku carbon dioxide, na-emegide ụkpụrụ nke mmepe akwụkwọ ndụ akwụkwọ ndụ.

Mgbe afọ anọ nke nyocha gasịrị, CNOOC ebutela ụzọ mbubata ọrụ mbụ nke China CCS (Carbon Capture and Storage) nke dị n'ebe mmanụ a, nwere ikike nchekwa CO₂ kwa afọ nke karịrị 100,000 tọn. N'ime ọnwa Mee nke afọ a, ewepụtara ọrụ CCUS mbụ nke China (Carbon Capture, Utilisation and Storage) n'elu ikpo okwu nke otu ebe mmanụ, na-enweta nkwalite zuru oke na akụrụngwa, teknụzụ, na injinia maka CCUS dị n'ụsọ mmiri. Site n'iji ụzọ teknụzụ iji kwalite mmepụta mmanụ na sequester CO₂, oru ngo a ewepụtala usoro ọhụrụ nke imegharị ike mmiri nke ejiri "iji CO₂ chụpụ mmịpụta mmanụ na ọnyà carbon site na mmepụta mmanụ." N'ime afọ iri na-abịanụ, a na-atụ anya na ala mmanụ a ga-etinye ihe karịrị otu nde tọn CO₂, na-akwalite mmepụta mmanụ site na ihe ruru tọn 200,000.

Xu Xiaohu, osote onye isi njikwa nke ụlọ ọrụ Enping Operations n'okpuru CNOOC Shenzhen Alaka, kwuru, sị: "Ebe ọ bụ na ọrụ gọọmentị na-arụ ọrụ, ọrụ a na-arụ ọrụ n'enweghị nsogbu ruo ihe karịrị awa 15,000, na-enwe ọnụ ọgụgụ kasị elu nke CO₂ kwa ụbọchị nke cubic mita 210,000.
