Isuswe isu elithi "bilial carbon", izimboni eziningi zenze indlela ecacile yokulondolozwa kwamandla nokuncishiswa kwekhabhoni. Ukuqashelwa kokungathathi hlangothi kwekhabhoni akuhlukaniswa kusuka ekusetshenzisweni kobuchwepheshe be-CCUS. Uhlelo lokusebenza oluthile lobuchwepheshe lwe-CCUS lubandakanya ukuthathwa kwekhabhoni, ukusetshenziswa kwekhabhoni kanye nokugcinwa, njll. Lolu chungechunge lwezobuchwepheshe ngokwemvelo lubandakanya ukufana kwe-valve. Ngokombono wezimboni ezihlobene nezinhlelo zokusebenza, ukuthuthukiswa kwesikhathi esizayo ithemba kufanelekile ukunakwa kwethuisivalwanaimboni.
Umqondo we-1.ccus kanye ne-Imboni Chain
Umqondo we.ccus
I-CCUS ingahle ibe engajwayelekile noma engajwayele kubantu abaningi. Ngakho-ke, ngaphambi kokuthi siqonde umthelela we-CCU embonini yeValve, ake sifunde nge-CCUS sindawonye. I-CCUS isifinyezo sesiNgisi (Casbon Capture, Ukusetshenziswa Kokugcina)
B.CCUS Imboni Chain.
Yonke i-CCUS Imboni Yezimboni ihlanganiswa ngokuyinhloko izixhumanisi ezinhlanu: Umthombo wokuphuma, ukuthwebula, ukuthutha, ukusetshenziswa nokugcinwa, nemikhiqizo. Izixhumanisi ezintathu zokuthwebula, izinto zokuhamba, ukusetshenziswa, ukugcinwa kanye nokugcina kuhlobene eduze nemboni yama-valve.
2. Umthelela we-CCUS onI-valveimboni
Ukuqhutshwa ukungathathi hlangothi kwekhabhoni, ukuqaliswa kokuthwebula ikhabhoni kanye nokugcinwa kwekhabhoni kuma-petrochemical, amandla we-thermal, insimbi, usimende, izimboni ezansi emkhakheni we-valve kuzokhula kancane, futhi kuzobonisa izici ezihlukile. Izinzuzo zomkhakha zizodedelwa kancane kancane, futhi kufanele sinake kakhulu intuthuko efanelekile. Isidingo sama-valves kulezi zimboni ezinhlanu ezilandelayo sizokhuphuka kakhulu.
A. Isidingo somkhakha we-petrochemical ngokokuqala ukugqamisa
Kulinganiselwa ukuthi ukuncishiswa kwe-Petrochemical's Petrochemical Ukuncishiswa kwe-Emistrumical kunesidingo samathani ayizigidi ezingama-50, futhi kuzokwehla kancane kuye ku-2040. Ngoba izindleko ze-petrochemical nezobuchwepheshe ziphansi, ukusetshenziswa kweCust Technology kube ngawokuqala ukuthuthukiswa kulo mkhakha. Ngo-2021, iSINOPEC izoqala ukwakhiwa kwephrojekthi ye-CCUS yokuqala yesigidi saseChina, i-QLU PETRHECHEMICAL-Shengli Oilfield CCUS Project. Ngemuva kokuthi iphrojekthi isiqediwe, izoba yisizinda esikhulu kunazo zonke se-CCUS CCUS CHANET CHANE CHANE EXTSHA eChina. Idatha enikezwe iSininopec ikhombisa ukuthi inani le-carbon dioxide elibanjwe yiSininopec ngo-2020 lifinyelele kumathani ayizigidi eziyi-1,3, lapho amathani angama-300,000 azosetshenziselwa ukuthuthukisa ukululama kawoyela okungahlanzekile nokunciphisa ukuphuma kwekhabhoni.
B. Isidingo semboni yamandla afudumele sizokwanda
Kusuka esimweni samanje, isidingo sama-valves embonini yamandla, ikakhulukazi imboni yamandla afudumele, ayikho mkhulu kakhulu, kepha ngaphansi kwengcindezi yecebo elithi "ikhebuli le-carbon", umsebenzi wamandla wekhabhoni "onamandla amakhulu aphethwe yi-coal. Ngokwesimo sezikhungo ezifanele: Isidingo sikagesi sezwe lami kulindeleke ukuthi sikhuphuke siye ku-12-15 trillion kwh ngo-2050, kanti amathani ama-430-1.64 billion e-carbon dioxide adinga ukwehliswa ngobuchwepheshe be-CCUS ukufeza ukuphuma kwe-zero. Uma isitshalo samandla asoshelwe amalahle sifakiwe nge-CCUS, singathatha ama-90% okukhishwa kwekhabhoni, okwenza kube ubuchwepheshe bokuphekelwa ngamandla kwekhabhoni. Isicelo se-CCUS yindlela eyinhloko yezobuchwepheshe yokubona ukuguquguquka kohlelo lwamandla. Kulokhu, isidingo sama-valves adalwe ukufakwa kwe-CCUs azokhuphuka kakhulu, futhi isidingo sama-valve emakethe yamandla, ikakhulukazi imakethe yamandla ashisayo, okuzokhombisa ukukhula okusha, okukufanelekela ukunakwa kwamabhizinisi emboni we-valve.
C. I-Steel kanye ne-Metallurgical Industry Design izokhula
Kulinganiselwa ukuthi ukuncishiswa kokukhishwa kwemali ngo-2030 kuzoba amathani ayizigidi ezingama-200 kuye kumathani ayizigidi ezingama-050 ngonyaka. Kuyaqapheleka ukuthi ngaphezu kokusetshenziswa kanye nokugcinwa kwekhabhoni diokda embonini yensimbi, futhi kungasetshenziswa ngqo kwinqubo yokwenza insimbi. Ukusebenzisa ngokugcwele lobu buchwepheshe bunganciphisa ukuphuma ngo-5% -10%. Kusukela kuleli phuzu lokubukwa, isidingo se-valve esifanele embonini yensimbi sizoshintsha izinguquko ezintsha, futhi isidingo sizokhombisa umkhuba obalulekile wokukhula.
D. Isidingo sezimboni zikasimende sizokhula kakhulu
Kulinganiselwa ukuthi ukuncishiswa kokukhishwa kwemali ngo-2030 kuzoba ngamathani ayizigidi eziyi-100 kuye kwezigidi ezingama-152 ngonyaka, kanti ukuncishiswa kokukhipha ngo-2060 kuzoba ngamathani ayizigidi ezingama-210 kuye ku-210 I-carbon dioxide ekhiqizwe ngokuwohloka kwe-limestone embonini kasimende ibiza cishe ama-60% okukhishwa okuphelele, ngakho-ke i-CCUS iyindlela edingekayo ye-deCarbonak yemboni kasimende.
I-E.Hydrogen Energy Energy Design izosetshenziswa kabanzi
Ukukhipha i-Hydrogen eluhlaza okwesibhakabhaka kusuka ku-methane kugesi yemvelo kudinga ukusetshenziswa kwenani elikhulu lama-valves, ngoba amandla athathwe kwinqubo yokukhiqizwa kwe-CO2, ukukhishwa kwekhabhoni kanye nokugcinwa (ama-CCS) kuyadingeka, futhi isitoreji kanye nokugcinwa kudinga ukusetshenziswa kwenani elikhulu lama-valve.
3. Iziphakamiso zoMkhakha weValve
I-Ccus izoba nesikhala esibanzi sentuthuko. Yize ibhekana nobunzima obuhlukahlukene, ngokuhamba kwesikhathi, i-CCU izoba nesikhala esibanzi sentuthuko, engacabangeki. Imboni yama-valve kufanele ilondoloze ukuqonda okucacile nokulungiselela ngokwengqondo kwalokhu. Kunconywe ukuthi imboni ye-valve isebenzise ngenkuthalo ye-CCUS Imboni
A. Bamba iqhaza ngenkuthalo kumaphrojekthi wokubukisa ama-CCUS. Kwephrojekthi ye-CCUS esetshenziswa eChina, ama-Enterprise embonini e-Valve kumele abambe iqhaza ekusetshenzisweni kwephrojekthi ngokwezobuchwepheshe kanye nocwaningo lomkhiqizo kanye nentuthuko, athola isipiliyoni sokwanela ukukhiqizwa kwephrojekthi enkulu kanye ne-valve ukuqhathanisa. Ubuchwepheshe, ithalente kanye nokugcinwa komkhiqizo.
B. Gxila ekuhlelweni kwemboni yamanje ye-CCUS Key. Gxila embonini yamandla amalahle lapho ubuchwepheshe be-carbon CapebuShone China busetshenziswa khona ikakhulukazi, kanye nemboni ye-petroleum lapho kugxilwe khona ama-valve ama-ccus ama-valves, bese ubeka ama-valves ezindaweni lapho izimboni zitholakala khona, okufana nezindawo ezikhiqiza amalahle. I-Bohai Bay Bay Basin kanye nePearl River Mouth Basin, okuyizindawo ezibalulekile ze-OIL negesi ekhiqiza, zisungule ubudlelwano obusondelene namabhizinisi afanele ukuze basebenzise ithuba.
C. Nikeza ukwesekwa okuthile kwezezimali kobuchwepheshe kanye nocwaningo lomkhiqizo kanye nokuthuthukiswa kwama-ccus project valves. Ukuze uhole emkhakheni we-valve wamaphrojekthi we-CCU ngokuzayo, kunconywa ukuthi izinkampani zezimboni zibeke eceleni imali ethize ocwaningweni nasekuthuthukisweni, futhi zinikeze ukwesekwa kwamaphrojekthi we-CCUs ngokwesimo semboni ye-CCUS.
Ngamafuphi, embonini ye-CCUS, kunconywa ukuthiI-valveUmkhakha uqonde ngokuphelele izinguquko ezintsha zezimboni ngaphansi kwesu "Dual-Carbon" kanye namathuba amasha entuthuko eza nakho, aqhubeke nezikhathi, futhi athole intuthuko entsha embonini!
