Iprojekthi yokuqala yaseTshayina yokugcina ikhabhoni ekude nonxweme ifezekisa inkqubela phambili, egqithisa kwi-100 yezigidi ze-cubic metres

NgoSeptemba 10, i-China National Offshore Oil Corporation (CNOOC) ibhengeze ukuba i-cumulative carbon dioxide storage volume ye-Enping 15-1 iprojekthi yokugcina i-oilfield yokugcina i-carbon-iprojekthi yokubonisa i-CO₂ ye-offshore yokuqala yase-China ebekwe kwi-Pearl River Mouth Basin-idlule i-100 yezigidi ze-cubic metres. Le mpumelelo ilingana nokunciphisa ukukhutshwa kwekhabhoni ngokutyala imithi ezizigidi ezi-2.2, nto leyo ephawula ukukhula kobugcisa bokugcina ikharbon diokside elunxwemeni lwaseTshayina, izixhobo, nobunjineli. Kubaluleke kakhulu ukukhawulezisa ukufezekiswa kweenjongo zelizwe “zekhabhoni ezimbini” kunye nokukhuthaza inguqu eluhlaza, enekhabhoni ephantsi kwezoqoqosho nezentlalo.

Njengoko indawo yeoli yokuqala enekhabhon diokside kwimpuma yoLwandle lwaseTshayina, indawo yeoli ye-Enping 15-1 iya kuthi, ukuba iphuhliswe kusetyenziswa iindlela eziqhelekileyo, ivelise ikharbon diokside kunye neoyile ekrwada. Oku akuyi kutshabalalisa kuphela izibonelelo zeqonga kude nonxweme kunye nemibhobho engaphantsi kolwandle kodwa ikwandise ukukhutshwa kwekharbon diokside, ephikisana nemithetho-siseko yophuhliso lohlaza.

Emva kweminyaka emine yophando, i-CNOOC iye yaphayona ukusasazwa kweprojekthi yokuqala yaseTshayina ye-CCS (iCarbon Capture kunye noGcino) kule ndawo yeoli, enomthamo wokugcina we-CO₂ wonyaka ongaphezulu kweetoni ze-100,000. NgoMeyi kulo nyaka, iprojekthi yokuqala yaseChina ye-CCUS (i-Carbon Capture, uSetyenziso kunye noGcino) yasungulwa kwiqonga lendawo yeoli efanayo, ifezekisa ukuphuculwa okubanzi kwezixhobo, iteknoloji, kunye nobunjineli be-CCUS engaselunxwemeni. Ngokusebenzisa iindlela zetekhnoloji ukomeleza imveliso ye-oyile ekrwada kunye ne-sequester CO₂, iprojekthi iseke imodeli entsha yokuphinda isetyenziswe amandla olwandle ephawulwa “ngokusebenzisa i-CO₂ ukuqhuba ukukhutshwa kwe-oyile kunye nokubambisa ikhabhoni ngokuvelisa i-oyile.” Kwiminyaka elishumi ezayo, i-oilfield kulindeleke ukuba ifake iitoni ezingaphezu kwesigidi esinye se-CO₂, ikhulise imveliso yeoli ekrwada ukuya kuthi ga kwiitoni ezingama-200,000.

Xu Xiaohu, uSekela Mlawuli Jikelele weNkampani yokuSebenza ye-Enping phantsi kweCNOOC yeSebe laseShenzhen, uthe: “Ukusukela ekugunyazisweni kwayo ngokusemthethweni, le projekthi ibisebenza ngokukhuselekileyo ngaphezulu kweeyure ezingama-15,000, ngencopho yemihla ngemihla yokutofa kweCO₂ ye-210,000 yee-cubic metres. Ukusetyenziswa kwekhabhoni ephantsi kumasimi e-oyile negesi engaselunxwemeni eTshayina limi njengempumelelo ebonakalayo kwiinzame zaseTshayina zokufezekisa iinjongo zayo zokungathabathi cala kwekhabhoni.

I-CNOOC ikhokela ngenkuthalo indlela yophuhliso lwe-CCUS engaselunxwemeni, iqhuba ukuvela kwayo ukusuka kwiiprojekthi zokubonisa ezizimeleyo ukuya ekwandeni okudibeneyo. Le nkampani isungule iprojekthi yokuqala yaseTshayina yokubamba ikhabhoni yezigidi ezilishumi zeetoni kunye neqela logcino eHuizhou, eGuangdong, eza kubamba ngokuchanekileyo ukukhutshwa kwekharbon diokside kumashishini akwingingqi yaseDaya Bay kwaye izithuthe ukuze zigcinwe kwiPearl River Mouth Basin. Eli nyathelo lijolise ekusekeni ikhonkco leshishini le-CCUS elipheleleyo nelinokhuphiswano lwamazwe ngamazwe.

Kwangaxeshanye, i-CNOOC isebenzisa ngokupheleleyo amandla abalulekileyo ekharbhon diokside ekwandiseni ukubuyiswa kweoyile kunye negesi. Izicwangciso ziyaqhubeka ukuseka iziko elisemantla leCO₂ eliphuculweyo lokubuyisela i-oyile eligxile kwindawo yerhasi ye-Bozhong 19-6, kunye nendawo esemazantsi yeCO₂ ephuculweyo yokubuyisela irhasi kwindawo yommandla werhasi yendalo kuMzantsi China woLwandle.

UWu Yiming, uMphathi weSebe leMveliso kwiCNOOC yeSebe laseShenzhen, uthe: "Uphuhliso oluzinzileyo lwetekhnoloji yeCCUS luya kubonelela ngenkxaso yobugcisa eTshayina ukufezekisa iinjongo zayo 'zekhabhoni ezimbini', ukuqhuba inguqu yoshishino lwamandla ukuya kuphuhliso oluluhlaza, oluphantsi kwekhabhoni, kunye nophuhliso oluzinzileyo, kwaye negalelo kwizisombululo zaseTshayina kunye namandla kulawulo lwemozulu yehlabathi.

I-SJPEE izinikele ekuphuhliseni izixhobo ezahlukeneyo zokwahlula imveliso kunye nezixhobo zokuhluza ioyile, igesi yendalo, kunye namashishini epetrochemical, afana ne-oyile / i-hydrocyclones yamanzi, ii-hydrocyclones zokususa isanti zamasuntswana akwinqanaba le-micron, iiyunithi zeflotation ezixineneyo, kunye nokunye. Sizibophelele ekuboneleleni ngobuchule obuphezulu bokwahlulwa kunye nezixhobo ezixhonywe ukutyibilika, kunye nohlengahlengiso lwezixhobo zomntu wesithathu kunye neenkonzo zasemva kokuthengisa. Ngamalungelo awodwa omenzi wepropathi enomgangatho ophezulu wokuqonda, inkampani iqinisekiswa phantsi kwe-DNV/GL-recognized ISO 9001, ISO 14001, kunye ne-ISO 45001 yolawulo lomgangatho kunye neenkqubo zenkonzo yokuvelisa.

Iimveliso ze-SJPEE zisetyenziswe ngokubanzi kumaqonga e-wellhead kunye namaqonga okuvelisa kwi-oyile kunye negesi yegesi efana ne-CNOOC, i-PetroChina, i-Petronas Malaysia, i-Indonesia, kunye ne-Gulf yaseThailand. Ngokuthunyelwa kumazwe amaninzi, zingqineke zithembeke kakhulu.
