Mashruucii ugu horeeyay ee Shiinuhu ee kaydinta kaarboonka ee xeebaha ka baxsan ayaa gaadhay horumar wayn, kaas oo ka badan 100 milyan oo mitir kuyuubik ah

Sebtembar 10, Shiinaha National Offshore Oil Corporation (CNOOC) ayaa ku dhawaaqday in mugga kaydinta kaarboon dioxide ee mashruuca kaydinta kaarboon ee Enping 15-1 oilfield — Shiinaha ee ugu horreeya mashruucii kaydinta CO₂ ee xeebta ee ku yaal Wabiga Pearl Basin - uu kor u dhaafay 100 milyan cubic mitir. Guushani waxay u dhigantaa dhimista qiiqa kaarboonka iyadoo la beerayo 2.2 milyan oo geed, taasoo calaamadaynaysa bisaylka tignoolajiyada kaydinta kaarboon laba ogsaydh ee Shiinaha ee xeebaha, qalabka, iyo awooda injineernimada. Waxay muhiimad weyn u leedahay dardargelinta xaqiijinta hadafyada "dual carbon" ee dalka iyo horumarinta isbeddelka dhaqaale iyo bulsho ee cagaaran, kaarboon-yar.

Sida saliidda saliidda ee ugu horreysa ee kaarboon dioxide-ka sare ee bariga Koonfurta Shiinaha, Enping 15-1 oilfield waxay, haddii la horumariyo iyadoo la adeegsanayo hababka caadiga ah, waxay soo saari doontaa kaarboon laba ogsaydh oo ay weheliso saliid cayriin. Tani kaliya ma duminayso tas-hiilaadka barxada xeebaha iyo dhuumaha badda hoosteeda, laakiin waxay sidoo kale kordhinaysaa qiiqa kaarboon laba ogsaydh, ka soo horjeeda mabaadi'da horumarinta cagaaran.

Ka dib afar sano oo cilmi baaris ah, CNOOC waxay hormuud ka noqotay daabulidda mashruucii ugu horreeyay ee Shiinaha ee xeebaha CCS (Kaarboon Qaadista iyo Kaydinta) ee goobtan saliidda, iyada oo awoodda kaydinta CO₂ sanadlaha ah ka badan 100,000 tan. Bishii Maajo ee sanadkan, mashruucii ugu horreeyay ee Shiinaha ee CCUS (Kaarboon Qaadista, Ka faa'iidaysiga iyo Kaydinta) ayaa laga bilaabay goobta saliidda, taas oo lagu gaadhay casriyeyn dhammaystiran oo xagga qalabka, tignoolajiyada, iyo injineernimada ee xeebaha CCUS. Iyada oo la adeegsanayo habab tignoolajiyadeed si kor loogu qaado wax soo saarka saliidda cayriin iyo sequester CO₂, mashruucu wuxuu dejiyay qaab cusub oo dib-u-warshadaynta tamarta badda oo lagu garto "isticmaalka CO₂ si loo wado soosaarka saliidda iyo kaarboonka iyada oo loo marayo soosaarka saliidda." Tobanka sano ee soo socda, goobta saliidda ayaa la filayaa in lagu duro in ka badan hal milyan oo tan oo CO₂ ah, taasoo kor u qaadaysa wax soo saarka saliidda cayriin ilaa 200,000 oo tan.

Xu Xiaohu, oo ah ku xigeenka maareeyaha guud ee shirkadda Enping Operations ee hoos timaada CNOOC Shenzhen Branch, ayaa yidhi: "Tan iyo markii la bilaabay hawlgelinta rasmiga ah, mashruucu wuxuu si badbaado leh u shaqeynayay in ka badan 15,000 saacadood, iyada oo la adeegsanayo kororka ugu sarreeya ee CO₂ maalin kasta oo ah 210,000 oo mitir cubic ah. Kaarboon-yar oo laga faa'iidaysto saliidda iyo gaaska badda ee Shiinaha.

CNOOC waxay si firfircoon u hogaaminaysaa isbeddelka horumarinta CCUS ee xeebaha, iyada oo kaxaynaysa horumarkeeda mashaariicda bandhigga ee kali-taliska ah ee ku wajahan ballaarinta kooxaysan. Shirkaddu waxa ay Huizhou, Guangdong, ka bilowday mashruucii ugu horreeyay ee Shiinaha ee qabashada iyo kaydinta kaarboonka ee toban milyan oo tan ah, kaas oo si sax ah u qaban doona qiiqa kaarboon-dioxide ee shirkadaha ku yaal aagga Daya Bay oo u qaadi doona kaydinta gudaha Webiga Pearl Basin. Dadaalkan ayaa ujeedadiisu tahay in la dhiso silsilad warshadeed CCUS oo dhammaystiran oo caalami ah oo tartan caalami ah leh.

Isla mar ahaantaana, CNOOC waxay si buuxda uga faa'iidaysanaysaa awoodda muhiimka ah ee kaarboon laba ogsaydh si ay kor ugu qaaddo soo kabashada saliidda iyo gaasta. Qorshayaasha ayaa socda si loo dhiso xarun shidaal oo la xoojiyey oo CO₂ ah oo xuddun u ah goobta gaaska ee Bozhong 19-6, iyo koonfurta CO₂-ka-soo-kabashada gaaska oo ka faa'iidaysata trillion-cubic-mitir gaaska dabiiciga ah ee gobolka Koonfurta Shiinaha.

Wu Yiming, oo ah Maareeyaha Waaxda Wax-soo-saarka ee Laanta Shenzhen ee CNOOC, ayaa yidhi: "Horumarinta joogtada ah ee tignoolajiyada CCUS waxay siin doontaa taageero farsamo oo Shiinaha ah si ay u gaadho himilooyinkeeda 'dual carbon', kaxaynta u gudubka warshadaha tamarta xagga cagaarka, karbon-yar, iyo horumar waara, waxayna gacan ka geysataa xalalka Shiinaha iyo xoogga maamulka cimilada adduunka. "

SJPEE waxay u heellan tahay inay soo saarto qalab kala duwan oo wax soo saar iyo qalab sifeyn ah oo loogu talagalay saliidda, gaaska dabiiciga ah, iyo warshadaha batroolka, sida saliidda / biyaha hydrocyclones, ciribtirka ciidda ka saarista qaybaha heerka-yar, unugyada sabbeynta is haysta, iyo in ka badan. Waxaa naga go'an inaan bixino kala saarid hufnaan sare leh iyo qalab ku rakiban skid, oo ay la socdaan wax ka beddelka qalabka dhinac saddexaad iyo adeegyada iibka kadib. Iyada oo leh shatiyada hantida garaadka ee madax-bannaan oo badan, shirkaddu waxay ku shahaadatay DNV/GL-la aqoonsan ISO 9001, ISO 14001, iyo ISO 45001 maamulka tayada iyo nidaamyada adeegga wax soo saarka.

Alaabooyinka SJPEE ayaa si weyn loogu isticmaalay goobaha ceelasha iyo meelaha wax soo saarka ee saliidda iyo gaaska sida CNOOC, PetroChina, Petronas Malaysia, Indonesia, iyo Gacanka Thailand. Wax dhoofinta dalal badan, waxay caddeeyeen inay yihiin kuwo la aamini karo.
