Tsav los ntawm "cov pa roj carbon" ob lub tswv yim, ntau yam kev lag luam tau txoj kev tiv thaiv kom muaj zog thiab kev txuag carbon. Qhov paub txog cov pa roj carbon neutrality yog inseparable los ntawm daim ntawv thov CCUS thev naus laus zis. Daim ntawv thov tshwj xeeb ntawm CCUS thev naus laus zis suav nrog cov tshuaj lis dej num, kev siv cov roj carbon thiab lwm yam, thiab lwm yam ntawm cov thev naus laus zis ntawm kev sib txuam nrog valves. Los ntawm qhov kev pom ntawm kev lag luam ntsig txog kev lag luam thiab kev siv, kev txhim kho yav tom ntej kev cia siab yog tsim nyog ntawm pebib lub dab tsi uas qhib thiab kawkev lag luam.
1.CCus tswvyim thiab kev lag luam saw
A.CCUS tswvyim
CCUs yuav tsis paub lossis txawm tias tsis paub txog ntau tus neeg. Yog li ntawd, ua ntej peb nkag siab qhov cuam tshuam ntawm CCUS ntawm kev lag luam valve, peb kawm txog CCUS ua ke. CCUs yog cov lus luv rau lus Askiv (Carbon ntes, siv thiab khoom lag luam)
B.CCUS kev lag luam saw.
Tag nrho CCus kev lag luam saw yog tsuas yog muaj li tsib txuas: Emission Purchs, ntes, kev thauj mus los, siv thiab khoom. Qhov peb txuas ntawm kev ntes, kev thauj mus los, kev siv thiab khaws cia yog ze rau kev lag luam valve.
2. Qhov cuam tshuam ntawm CCUS ntawmlub pob valvekev ua hauj lwm
Tsav los ntawm cov pa roj carbon neutrality, kev siv cov pa roj carbon kev ntes thiab cov khoom lag luam thement, luam ntawv thiab lwm yam kev lag luam hauv lub valve yuav maj mam nce, thiab yuav qhia cov yam ntxwv sib txawv. Cov txiaj ntsig ntawm kev lag luam yuav maj mam muab tso tawm, thiab peb yuav tsum saib xyuas kom zoo rau cov kev txhim kho tsis zoo. Qhov kev thov rau cov li qub nyob rau hauv tsib kev lag luam yuav nce ntxiv.
A. Qhov kev thov ntawm petrochemical kev lag luam yog thawj qhov tseem ceeb
Nws tau kwv yees tias kuv lub teb chaws lub petrochemical txo cov nqi hauv 20 ntawm kev lag luam me me, thiab kev lag luam tsis tshua muaj roj carbon dioxide tau ua thawj zaug uas tau nce hauv daim teb no. Xyoo 2021, Sinopec yuav pib kev tsim kho ntawm Tuam Tshoj thawj lab-TUJ CCUS Project, Qilu Petrochemical-Shengli Oilfield CCUS. Tom qab lub phiaj xwm tiav, nws yuav dhau los ua CCU tshaj plaws puv nkaus-kev lag luam saw ua qauv qhia hauv Suav teb. Cov ntaub ntawv muab los ntawm Sinopec qhia tau tias tus nqi ntawm cov pa roj carbon dioxide tau txais rau kev txhim kho cov txiaj ntsig roj av tau rov qab thiab txo cov roj carbon emissions.
B. Qhov thov rau thermal zog kev lag luam yuav nce ntxiv
Los ntawm cov xwm txheej tam sim no, qhov kev thov rau li qub hauv kev lag luam muaj zog, tab sis nyob rau hauv lub siab ntawm lub zog ua haujlwm ntawm lub zog hluav taws xob ntawm lub zog hluav taws xob ntawm cov khoom siv hluav taws xob ntau dua. Raws li kev kwv yees ntawm cov tsev uas muaj feem xyuam: Kuv lub teb chaws hluav taws xob thov yuav tsum tau txo mus rau CCUS thev naus laus zis kom ua tiav cov khoom siv hluav taws xob. Yog tias lub tshuab tua hluav taws fais fab tuag yog ntsia nrog CCUS, nws tuaj yeem ntes 90% ntawm cov pa roj carbon emissions, ua rau nws cov roj carbon fais fab tsim thev naus laus zis. CCUS Daim Ntawv Thov yog cov txhais tau hais tias kom paub qhov yooj yim ntawm lub zog hluav taws xob. Hauv qhov no, qhov kev thov rau cov li qub tshwm sim los ntawm lub installation yuav nce ntxiv, thiab qhov kev tsim nyog ntawm lub zog loj, thiab tsim nyog rau kev loj hlob tshiab, uas yog tsim nyog ntawm kev saib xyuas tshiab ntawm valve kev lag luam.
C. Hlau thiab Metallurgical Kev Xav Lag Luam Yuav Loj Hlob
Nws yog kwv yees tias emission txo cov kev thov hauv 2030 yuav yog 200 lab tons mus 050 lab tons nyob rau ib xyoo. Nws yog tsim nyog sau cia uas ntxiv rau kev siv thiab cov pa roj carbon dioxide hauv kev lag luam steel, nws kuj tuaj yeem siv tau ncaj qha rau hauv cov txheej txheem statmakakakaking. Siv tag nrho cov txiaj ntsig ntawm cov thev naus laus zis tuaj yeem txo cov pa hluav taws los ntawm 5% -10%. Txij ntawm no mus saib, lub valve cuam tshuam thov hauv cov hlau kev lag luam yuav yauv hloov tshiab, thiab qhov kev thov yuav qhia qhov kev loj hlob tseem ceeb.
D. CAs kev lag luam kev lag luam yuav loj hlob ntau
Nws yog kwv yees tias emission txo cov kev thov hauv 2030 yuav yog 100 lab tons rau 2060 yuav yog 190 lab tons rau 210 lab tons ib xyoos. Cov pa roj carbon dioxide tsim los ntawm cov decomposition ntawm limestone hauv cov kev lag luam xiss rau txog 60% ntawm tag nrho cov kev tsim nyog, yog li CCUs yog qhov tsim nyog ntawm kev lag luam cement.
E.hydogen zog zog kev lag luam thov yuav tau siv dav
Muab cov tshuaj ntsuab xiav los ntawm methane nyob rau hauv cov pa roj uas yuav tsum tau siv los ntawm cov txheej txheem ntawm CO2 ntau lawm, thiab kev sib kis (CCS)
3. Cov lus qhia rau lub valve kev lag luam
CCUS yuav muaj qhov chaw dav dav rau kev txhim kho. Txawm hais tias nws ntsib ntau yam nyuaj, hauv kev khiav ntev, CCUS yuav muaj qhov chaw dav dav rau kev txhim kho, uas yog unquestionable. Lub Valve Kev Lag Luam yuav tsum muaj kev nkag siab meej thiab ua kom muaj kev xav tau zoo rau qhov no. Nws raug pom zoo tias kev lag luam valve kom puas tau CCUS kev lag luam ntsig txog cov teb
A. nquag koom nrog CCUs ua qauv qhia. Rau CCUs Project tau siv nyob rau hauv Suav teb, lub chaw lag luam valve yuav tsum koom tes nrog kev ua haujlwm ntawm txoj haujlwm, thiab kev tsim kho kom txaus rau qhov txuas ntxiv loj loj thiab valve sib txuam. Thev naus laus zis, txuj ci thiab khoom lag luam muag khoom.
B. Tsom rau lub CCU kev lag luam tseem ceeb tam sim no. Tsom rau cov kev lag luam fais fab tuag uas suav nrog cov khoom lag luam CCUS, thiab cov khoom lag luam roj av uas muaj cov phiab, uas yog qhov tseem ceeb rau cov chaw tsim hluav taws xob. Cov Bohaai Bay phiab thiab cov roj teeb tseem ceeb thiab roj av tsim khoom, tau teeb tsa kev sib koom tes nrog cov khoom lag luam uas muaj feem xyuam.
C. Muab qee yam nyiaj txiag rau kev siv nyiaj thev naus laus zis thiab kev tshawb fawb txog CCUS CCUS CCUS. Txhawm rau coj cov hmoov txhuas hauv qhov dej num ccus ntawm CCUS cov peev txheej hauv kev tshawb fawb thiab kev txhim kho cov tuam txhab kev tshawb fawb txog kev ua lag luam ntawm CCUS kev lag luam.
Hauv ntej, rau CCUS kev lag luam, nws raug nquahu komlub pob valveKev lag luam tau nkag siab txog cov kev hloov pauv tshiab hauv qab "dual-carbon" zoo thiab cov kev txhim kho tshiab, thiab ua tiav kev loj hlob tshiab hauv kev lag luam!
