Eqhutywa sisicwangciso se-"dual carbon", amashishini amaninzi enze indlela ecacileyo yokugcinwa kwamandla kunye nokunciphisa i-carbon. Ukuzaliseka kokungathathi hlangothi kwekhabhoni akunakwahlulwa ekusebenziseni iteknoloji yeCCUS. Ukusetyenziswa okuthe ngqo kobuchwepheshe be-CCUS kubandakanya ukubanjwa kwekhabhoni, ukusetyenziswa kwekhabhoni kunye nokugcinwa, njl njl. Olu luhlu lwezicelo zeteknoloji ngokwemvelo lubandakanya ukuhambelana kwevalve. Ngokombono wamashishini anxulumeneyo kunye nezicelo, uphuhliso lwexesha elizayo Ithemba liyifanele ingqalelo yethuivalveishishini.
I-1.CCUS ingcamango kunye nekhonkco loshishino
A.CCUS ingqiqo
I-CCUS isenokuba ayiqhelekanga okanye ayiqhelekanga kubantu abaninzi. Ke ngoko, phambi kokuba siqonde ifuthe le-CCUS kushishino lwevalvu, masifunde nge-CCUS kunye. I-CCUS sisishunqulelo sesiNgesi (iCarbon Capture, Usetyenziso kunye noGcino)
B.CCUS ikhonkco loshishino.
Ikhonkco leshishini le-CCUS liphela liqulunqwe kakhulu ngamakhonkco amahlanu: umthombo wokukhupha, ukubamba, ukuthutha, ukusetyenziswa kunye nokugcinwa, kunye neemveliso. Amakhonkco amathathu okubamba, ukuthutha, ukusetyenziswa kunye nokugcinwa anxulumene ngokusondeleyo kwishishini levalvu.
2. Impembelelo ye-CCUS kwiivalveishishini
Ukuqhutywa kukungathathi hlangothi kwekhabhoni, ukuphunyezwa kwekhabhoni yokubamba kunye nokugcinwa kwekhabhoni kwi-petrochemical, amandla okushisa, insimbi, i-samente, ukuprinta kunye namanye amashishini ezantsi kweshishini le-valve liya kwanda ngokuthe ngcembe, kwaye liya kubonisa iimpawu ezahlukeneyo. Izibonelelo zolu shishino ziya kukhutshwa ngokuthe ngcembe, kwaye kufuneka sinikele ingqwalasela enkulu kuphuhliso olufanelekileyo. Imfuno yeevalvu kula mashishini mahlanu alandelayo iya kwanda kakhulu.
A. Imfuno yoshishino lwepetrochemical yeyokuqala ukugqamisa
Kuqikelelwa ukuba imfuno yokunciphisa i-petrochemical emission yelizwe lam ngo-2030 imalunga ne-50 yezigidi zeetoni, kwaye iya kuncipha ngokuthe ngcembe ukuya kwi-0 ngo-2040. , iindleko zotyalo-mali kunye neendleko zokusebenza kunye nokugcinwa kweendleko ziphantsi, ukusetyenziswa kweteknoloji ye-CUSS ibe ngowokuqala ukukhuthazwa kule ntsimi. Ngo-2021, i-Sinopec iya kuqalisa ukwakhiwa kweprojekthi ye-CCUS yezigidi zeetoni zokuqala zaseTshayina, iprojekthi yeQilu Petrochemical-Shengli Oilfield CCUS. Emva kokuba iprojekthi igqityiwe, iya kuba sesona siseko sikhulu se-CCUS esigcwele umzi-mveliso eTshayina. Idatha enikezwe yiSinopec ibonisa ukuba inani le-carbon dioxide ebanjwe yiSinopec ngo-2020 lifikelele malunga neetoni ze-1.3 yezigidi, apho iitoni ezingama-300,000 ziya kusetyenziselwa ukukhukula kweoli, okuye kwafumana iziphumo ezilungileyo ekuphuculeni ukubuyiswa kweoli ekrwada kunye nokunciphisa ukukhutshwa kwekhabhoni. .
B. Imfuno yoshishino lwamandla ashushu iya kwanda
Ukususela kwimeko yangoku, imfuno yeevalvu kwishishini lamandla, ngakumbi imboni yamandla e-thermal, ayinkulu kakhulu, kodwa phantsi koxinzelelo lweqhinga "lekhabhoni ezimbini", umsebenzi we-carbon neutralization yezityalo zamandla ezitshiswa ngamalahle uya ukhula. nzima. Ngokutsho koqikelelo lwamaziko afanelekileyo: imfuno yombane yelizwe lam kulindeleke ukuba inyuke ukuya kwi-12-15 yetriliyoni kWh ngo-2050, kunye ne-430-1.64 yeebhiliyoni zeetoni ze-carbon dioxide kufuneka zincitshiswe ngeteknoloji ye-CCUS ukuphumeza ukukhutshwa kwe-zero kwi-net . Ukuba isityalo sombane esifakwe ngamalahle sifakwe kunye ne-CCUS, sinokubamba i-90% yokukhutshwa kwekhabhoni, okwenza kube yiteknoloji yokuvelisa amandla ekhabhoni ephantsi. Isicelo se-CCUS sesona sixhobo siphambili zobugcisa ukuqonda ukuguquguquka kwenkqubo yamandla. Kule meko, imfuno yeevalvu ezibangelwa ukufakwa kwe-CCUS iya kunyuka kakhulu, kwaye imfuno yeevalvu kwimarike yamandla, ngakumbi imarike yamandla obushushu, iya kubonisa ukukhula okutsha, okufanelekile ukuqwalaselwa kwamashishini amashishini e-valve.
C. Steel kunye nemveliso metallurgical imfuno iya kukhula
Kuqikelelwa ukuba imfuno yokunciphisa ukukhutshwa kwemveliso ngo-2030 iya kuba yi-200 yezigidi zeetoni ukuya kwi-050 yezigidi zeetoni ngonyaka. Kuyafaneleka ukuba uqaphele ukuba ngaphezu kokusetyenziswa kunye nokugcinwa kwe-carbon dioxide kwishishini lensimbi, linokusetyenziswa ngokuthe ngqo kwinkqubo yokwenza insimbi. Ukusebenzisa ngokupheleleyo obu buchwepheshe kunokunciphisa ukukhutshwa kwe-5% -10%. Ukususela kulo mbono, imfuno ye-valve efanelekileyo kwishishini lensimbi iya kutshintsha utshintsho olutsha, kwaye imfuno iya kubonisa ukukhula okuphawulekayo.
D. Imfuno yoshishino lwesamente iya kukhula kakhulu
Kuqikelelwa ukuba imfuno yokunciphisa i-emission ngo-2030 iya kuba yi-100 yezigidi zeetoni ukuya kwi-152 yezigidi zeetoni ngonyaka, kwaye imfuno yokunciphisa i-emission ngo-2060 iya kuba yi-190 yezigidi zeetoni ukuya kwi-210 yezigidi zeetoni ngonyaka. Ikharbon diokside eveliswa kukubola kwekalika kwishishini lesamente ithatha malunga ne-60% yokukhutshwa okupheleleyo, ngoko ke i-CCUS yindlela eyimfuneko yokuphelisa ikhabhoni kushishino lwesamente.
Imfuno yoshishino lwamandla e-Hydrogen iya kusetyenziswa ngokubanzi
Ukukhupha i-hydrogen eluhlaza okwesibhakabhaka kwi-methane kwigesi yendalo kufuna ukusetyenziswa kwenani elikhulu leevalvu, kuba amandla athathwe kwinkqubo yokuvelisa i-CO2, ukubanjwa kwekhabhoni kunye nokugcinwa (CCS) kuyimfuneko, kwaye ukuhanjiswa kunye nokugcinwa kufuna ukusetyenziswa kwesixhobo esikhulu. inani leevalvu.
3. Iingcebiso kushishino lwevalvu
I-CCUS iya kuba nendawo ebanzi yophuhliso. Nangona ijongene nobunzima obahlukeneyo, ekuhambeni kwexesha, i-CCUS iya kuba nendawo ebanzi yophuhliso, engathandabuzekiyo. Ishishini levalvu kufuneka ligcine ukuqonda okucacileyo kunye nokulungiswa okwaneleyo kwengqondo koku. Kwenziwa isincomo sokuba ishishini levalvu lisasaze imimandla enxulumene noshishino lweCCUS
A. Thatha inxaxheba ngokukhutheleyo kwiiprojekthi zokubonisa ze-CCUS. Kuba iprojekthi ye-CCUS iphunyezwa e-China, amashishini oshishino lwevalvu kufuneka athathe inxaxheba ngokukhutheleyo ekuphunyezweni kweprojekthi ngokwemigaqo yobugcisa kunye nophando lwemveliso kunye nophuhliso, amava ashwankathela kwinkqubo yokuthatha inxaxheba ekuphunyezweni kweprojekthi, kwaye enze ngokwaneleyo. amalungiselelo emveliso yobunzima obulandelayo kunye nokulinganisa ivalvu. Itekhnoloji, italente kunye noovimba bemveliso.
B. Gxininisa kubume beshishini obungundoqo be-CCUS. Ugxininiso kushishino lwamandla amalahle apho iteknoloji yaseTshayina yokubamba itekhnoloji isetyenziswa kakhulu, kunye neshishini lepetroleum apho ugcino lwejoloji lugxininiswe ukuze kufakwe iivalvu zeprojekthi yeCCUS, kunye nokusasaza iivalvu kwiindawo apho ezi mizi-mveliso zikhoyo, njenge Ordos Basin kunye ne I-Junggar-Tuha Basin, eziyimimandla ebalulekileyo yokuvelisa amalahle. IBohai Bay Basin kunye nePearl River Mouth Basin, eziyimimandla ebalulekileyo yokuvelisa i-oli negesi, ziseke ubudlelwane obusondeleyo bentsebenziswano namashishini afanelekileyo ukuze kuxhaswe eli thuba.
C. Ukubonelela ngenkxaso ethile yezemali kubuchwepheshe kunye nophando lwemveliso kunye nophuhliso lweevalvu zeprojekthi yeCCUS. Ukuze ukhokele kwibala levalvu yeeprojekthi zeCCUS kwixesha elizayo, kucetyiswa ukuba iinkampani zoshishino zibekele bucala isixa esithile semali kuphando nophuhliso, kwaye zinike inkxaso kwiiprojekthi zeCCUS ngokwemigaqo yophando lweteknoloji nophuhliso, ngoko ke njengokudala imeko-bume elungileyo yoyilo loshishino lweCCUS.
Ngamafutshane, kwishishini le-CCUS, kucetyiswa ukubaivalveimboni iqonda ngokupheleleyo utshintsho olutsha lwemizi-mveliso phantsi kwesicwangciso-qhinga se-"dual-carbon" kunye namathuba amatsha ophuhliso oluza nalo, ukuhamba kunye namaxesha, kunye nokufezekisa uphuhliso olutsha kwishishini!
