Tsav los ntawm "dual carbon" lub tswv yim, ntau qhov kev lag luam tau tsim txoj hauv kev zoo rau kev txuag hluav taws xob thiab txo cov pa roj carbon monoxide. Lub realization ntawm carbon neutrality yog inseparable los ntawm kev siv CCUS technology. Daim ntawv thov tshwj xeeb ntawm CCUS thev naus laus zis suav nrog kev ntes cov pa roj carbon monoxide, kev siv cov pa roj carbon monoxide thiab khaws cia, thiab lwm yam. Cov kev siv thev naus laus zis no ib txwm muaj feem cuam tshuam nrog valve. Los ntawm qhov kev xav ntawm kev lag luam thiab kev siv, kev txhim kho yav tom ntej Lub zeem muag tsim nyog rau kev saib xyuas ntawm pebvalvekev lag luam.
1.CCUS tswvyim thiab kev lag luam saw
A.CCUS tswvyim
CCUS tej zaum yuav tsis paub lossis tsis paub rau ntau tus neeg. Yog li ntawd, ua ntej peb nkag siab txog qhov cuam tshuam ntawm CCUS ntawm kev lag luam valve, cia peb kawm txog CCUS ua ke. CCUS yog cov ntawv luv rau lus Askiv (Carbon Capture, Siv thiab Cia)
B.CCUS kev lag luam saw.
Tag nrho CCUS kev lag luam saw yog tsim los ntawm tsib qhov txuas: emission source, capture, tsheb thauj mus los, siv thiab cia, thiab cov khoom. Peb qhov kev sib txuas ntawm kev ntes, kev thauj mus los, kev siv thiab kev khaws cia yog ze rau kev lag luam valve.
2. Qhov cuam tshuam ntawm CCUS raulub valvekev lag luam
Tsav los ntawm carbon neutrality, qhov kev siv ntawm carbon capture thiab carbon cia nyob rau hauv petrochemical, thermal zog, steel, cement, luam ntawv thiab lwm yam lag luam downstream ntawm valve kev lag luam yuav maj mam nce, thiab yuav qhia txawv cov yam ntxwv. Cov txiaj ntsig ntawm kev lag luam yuav maj mam tso tawm, thiab peb yuav tsum tau ua tib zoo saib xyuas cov kev txhim kho cuam tshuam. Qhov kev thov rau li qub hauv tsib qhov kev lag luam hauv qab no yuav nce ntxiv.
A. Qhov kev thov ntawm kev lag luam petrochemical yog thawj qhov tseem ceeb
Nws yog kwv yees hais tias kuv lub teb chaws petrochemical emission txo kev thov nyob rau hauv 2030 yog hais txog 50 lab tons, thiab nws yuav maj mam txo mus rau 0 los ntawm 2040. Vim hais tias cov petrochemical thiab tshuaj industries yog lub ntsiab cheeb tsam ntawm kev siv cov pa roj carbon dioxide, thiab capture ntawm tsawg zog noj. , cov nqi peev thiab kev ua haujlwm thiab kev saib xyuas cov nqi qis, daim ntawv thov ntawm CUSS thev naus laus zis tau ua thawj zaug los txhawb hauv daim teb no. Xyoo 2021, Sinopec yuav pib tsim Tuam Tshoj thawj lab-tuj CCUS qhov project, Qilu Petrochemical-Shengli Oilfield CCUS project. Tom qab qhov project tiav, nws yuav dhau los ua qhov loj tshaj plaws CCUS kev lag luam saw hlau ua qauv qhia hauv Suav teb. Cov ntaub ntawv muab los ntawm Sinopec qhia tau hais tias cov pa roj carbon dioxide ntes tau los ntawm Sinopec xyoo 2020 tau txog li 1.3 lab tons, ntawm 300,000 tons yuav siv rau cov roj av dej nyab, uas tau ua tiav cov txiaj ntsig zoo hauv kev txhim kho cov roj av rov qab thiab txo cov pa roj carbon monoxide. .
B. Qhov kev thov rau thermal fais fab kev lag luam yuav nce
Los ntawm qhov xwm txheej tam sim no, qhov kev thov rau li qub hauv kev lag luam hluav taws xob, tshwj xeeb tshaj yog kev lag luam hluav taws xob thermal, tsis yog loj heev, tab sis nyob rau hauv lub siab ntawm "dual carbon" lub tswv yim, cov pa roj carbon neutralization hauj lwm ntawm cov thee hluav taws xob fais fab nroj tsuag tau nce zuj zus. kev nyuaj siab. Raws li kev kwv yees ntawm cov koom haum cuam tshuam: kuv lub teb chaws qhov kev thov hluav taws xob yuav tsum nce mus rau 12-15 trillion kWh los ntawm 2050, thiab 430-1.64 billion tons ntawm carbon dioxide yuav tsum tau txo los ntawm CCUS thev naus laus zis kom ua tiav net xoom emissions hauv lub zog hluav taws xob. . Yog tias lub tuam txhab hluav taws xob hluav taws xob tau teeb tsa nrog CCUS, nws tuaj yeem ntes tau 90% ntawm cov pa roj carbon emissions, ua rau nws muaj cov tshuab hluav taws xob tsawg-carbon. CCUS daim ntawv thov yog lub ntsiab kev txhais tau tias kom paub qhov yooj ntawm lub hwj chim system. Nyob rau hauv cov ntaub ntawv no, qhov kev thov rau li qub los ntawm kev teeb tsa ntawm CCUS yuav nce ntxiv, thiab qhov kev thov rau li qub hauv kev lag luam fais fab, tshwj xeeb tshaj yog cov thermal fais fab kev lag luam, yuav qhia txog kev loj hlob tshiab, uas tsim nyog rau kev mloog ntawm valve kev lag luam kev lag luam.
C. Hlau thiab metallurgical kev lag luam xav tau yuav loj hlob
Nws tau kwv yees tias qhov kev thov txo qis hauv 2030 yuav yog 200 lab tons rau 050 lab tons hauv ib xyoos. Nws yog tsim nyog sau cia tias ntxiv rau kev siv thiab khaws cia cov pa roj carbon dioxide hauv kev lag luam steel, nws tseem tuaj yeem siv ncaj qha rau hauv cov txheej txheem steelmaking. Ua kom zoo dua ntawm cov thev naus laus zis no tuaj yeem txo qis emissions los ntawm 5% -10%. Los ntawm qhov kev pom no, qhov cuam tshuam valve xav tau hauv kev lag luam steel yuav raug hloov pauv tshiab, thiab qhov kev thov yuav qhia txog kev loj hlob tseem ceeb.
D. Cement kev lag luam xav tau yuav loj tuaj
Nws tau kwv yees tias qhov kev thov txo qis emission nyob rau xyoo 2030 yuav yog 100 lab tons rau 152 lab tons hauv ib xyoos, thiab kev txo qis emission xav tau hauv 2060 yuav yog 190 lab tons rau 210 lab tons hauv ib xyoos. Cov pa roj carbon dioxide uas tsim los ntawm decomposition ntawm limestone nyob rau hauv cov cement kev lag luam suav txog li 60% ntawm tag nrho cov emissions, yog li CCUS yog ib tug tsim nyog txhais tau tias rau decarbonization ntawm cov cement kev lag luam.
E.Hydrogen zog kev lag luam xav tau yuav siv dav
Extracting xiav hydrogen los ntawm methane nyob rau hauv natural gas yuav tsum tau siv ntau lub li qub, vim hais tias lub zog yog ntes los ntawm cov txheej txheem ntawm CO2 ntau lawm, carbon capture thiab cia (CCS) yog tsim nyog, thiab kis tau tus mob thiab cia yuav tsum tau siv ib tug loj. tus naj npawb ntawm li qub.
3. Cov lus qhia rau kev lag luam valve
CCUS yuav muaj qhov dav dav rau kev txhim kho. Txawm hais tias nws ntsib ntau yam teeb meem, nyob rau lub sijhawm ntev, CCUS yuav muaj qhov dav dav rau txoj kev loj hlob, uas yog qhov tsis txaus ntseeg. Kev lag luam valve yuav tsum muaj kev nkag siab meej thiab kev npaj siab txaus rau qhov no. Nws raug pom zoo tias kev lag luam valve nquag siv CCUS kev lag luam ntsig txog kev lag luam
A. Koom tes nrog CCUS kev ua qauv qhia. Rau CCUS qhov project tau siv nyob rau hauv Suav teb, lub valve kev lag luam tuam txhab yuav tsum nquag koom nrog rau kev siv ntawm qhov project nyob rau hauv cov nqe lus ntawm kev siv technology thiab cov khoom tshawb fawb thiab kev loj hlob, suav nrog cov kev paub nyob rau hauv tus txheej txheem ntawm kev koom tes nyob rau hauv qhov project, thiab ua kom txaus. kev npaj rau cov khoom loj tom ntej thiab kev sib tw valve. Technology, txuj ci thiab khoom reserves.
B. Tsom ntsoov rau qhov tam sim no CCUS tseem ceeb kev lag luam layout. Tsom ntsoov rau kev lag luam thee hluav taws xob uas Tuam Tshoj cov pa roj carbon capture thev naus laus zis feem ntau yog siv, thiab kev lag luam roj av qhov chaw khaws cia geological tsom mus rau xa CCUS qhov project li qub, thiab xa cov li qub rau hauv thaj chaw uas cov kev lag luam no nyob, xws li Ordos Basin thiab. Junggar-Tuha Basin, uas yog cov chaw tsim khoom lag luam tseem ceeb. Lub Bohai Bay Basin thiab Pearl River Qhov ncauj Basin, uas yog cov chaw tsim khoom roj thiab roj tseem ceeb, tau tsim kev sib raug zoo nrog cov lag luam uas cuam tshuam los txeeb lub sijhawm.
C. Muab qee qhov kev txhawb nqa nyiaj txiag rau kev siv thev naus laus zis thiab cov khoom lag luam tshawb fawb thiab kev tsim kho ntawm CCUS qhov project li qub. Txhawm rau ua tus thawj coj hauv thaj chaw valve ntawm CCUS cov haujlwm yav tom ntej, nws raug pom zoo tias cov tuam txhab kev lag luam tau tso tseg qee qhov nyiaj hauv kev tshawb fawb thiab kev tsim kho, thiab muab kev txhawb nqa rau CCUS cov haujlwm hauv cov ntsiab lus ntawm kev tshawb fawb thiab kev tsim kho technology, yog li ntawd. raws li tsim kom muaj ib puag ncig zoo rau kev teeb tsa ntawm CCUS kev lag luam.
Hauv luv luv, rau CCUS kev lag luam, nws raug pom zoo tiaslub valvekev lag luam nkag siab txog cov kev hloov pauv tshiab hauv kev lag luam raws li "dual-carbon" lub tswv yim thiab cov hauv kev tshiab rau kev txhim kho uas tuaj nrog nws, ua kom nrawm nrog lub sijhawm, thiab ua tiav txoj kev loj hlob tshiab hauv kev lag luam!
