Tsav los ntawm txoj kev npaj "ob chav carbon", ntau lub lag luam tau tsim txoj hauv kev meej rau kev txuag hluav taws xob thiab txo cov pa roj carbon. Kev paub txog qhov tsis muaj pa roj carbon yog qhov tsis sib cais los ntawm kev siv thev naus laus zis CCUS. Daim ntawv thov tshwj xeeb ntawm thev naus laus zis CCUS suav nrog kev ntes cov pa roj carbon, kev siv cov pa roj carbon thiab kev khaws cia, thiab lwm yam. Cov ntawv thov thev naus laus zis no suav nrog kev sib phim valve. Los ntawm qhov pom ntawm cov lag luam thiab cov ntawv thov cuam tshuam, kev txhim kho yav tom ntej Lub zeem muag tsim nyog rau kev saib xyuas ntawm peblub valvekev lag luam.
1. Lub tswv yim CCUS thiab cov saw hlau lag luam
Lub tswv yim A.CCUS
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 rau kev lag luam valve, cia peb kawm txog CCUS ua ke. CCUS yog lub npe luv rau lus Askiv (Carbon Capture, Utilization and Storage)
B.CCUS kev lag luam saw.
Tag nrho cov saw hlau lag luam CCUS feem ntau yog tsim los ntawm tsib qhov txuas: qhov chaw tso pa tawm, kev ntes, kev thauj mus los, kev siv thiab kev khaws cia, thiab cov khoom lag luam. Peb qhov txuas ntawm kev ntes, kev thauj mus los, kev siv thiab kev khaws cia muaj feem cuam tshuam nrog kev lag luam valve.
2. Qhov cuam tshuam ntawm CCUS raulub valvekev lag luam
Tsav los ntawm kev tsis muaj pa roj carbon, kev siv cov pa roj carbon thiab khaws cov pa roj carbon hauv petrochemical, thermal power, hlau, cement, luam ntawv thiab lwm yam lag luam hauv qab ntawm kev lag luam valve yuav maj mam nce ntxiv, thiab yuav qhia txog cov yam ntxwv sib txawv. Cov txiaj ntsig ntawm kev lag luam yuav maj mam tso tawm, thiab peb yuav tsum tau ua tib zoo mloog rau cov kev txhim kho tseem ceeb. Qhov kev thov rau cov li qub hauv tsib lub lag luam hauv qab no yuav nce ntxiv ntau heev.
A. Qhov kev thov ntawm kev lag luam petrochemical yog thawj qhov uas yuav tsum tau hais txog
Kwv yees tias kuv lub teb chaws qhov kev thov txo qis kev tso pa tawm hauv petrochemical hauv xyoo 2030 yog li 50 lab tons, thiab nws yuav maj mam txo qis mus rau 0 los ntawm xyoo 2040. Vim tias cov lag luam petrochemical thiab tshuaj lom neeg yog cov chaw tseem ceeb ntawm kev siv cov pa roj carbon dioxide, thiab kev ntes cov kev siv hluav taws xob tsawg, cov nqi peev thiab cov nqi ua haujlwm thiab kev saib xyuas qis, kev siv CUSS thev naus laus zis tau yog thawj qhov kev txhawb nqa hauv daim teb no. Xyoo 2021, Sinopec yuav pib tsim kho Tuam Tshoj thawj lab-ton CCUS project, Qilu Petrochemical-Shengli Oilfield CCUS project. Tom qab qhov project tiav, nws yuav dhau los ua qhov chaw ua qauv qhia loj tshaj plaws ntawm CCUS hauv Suav teb. Cov ntaub ntawv los ntawm Sinopec qhia tau hais tias qhov ntau ntawm cov pa roj carbon dioxide uas Sinopec ntes tau hauv xyoo 2020 tau txog li 1.3 lab tons, ntawm cov uas 300,000 tons yuav siv rau kev dej nyab hauv thaj chaw roj, uas tau ua tiav cov txiaj ntsig zoo hauv kev txhim kho kev rov qab roj av thiab txo cov pa roj carbon dioxide.
B. Qhov kev thov rau kev lag luam fais fab thermal yuav nce ntxiv
Los ntawm qhov xwm txheej tam sim no, qhov kev thov rau cov li qub hauv kev lag luam fais fab, tshwj xeeb tshaj yog kev lag luam fais fab thermal, tsis loj heev, tab sis nyob rau hauv qhov kev nyuaj siab ntawm "ob lub carbon", txoj haujlwm carbon neutralization ntawm cov chaw tsim hluav taws xob thee tau dhau los ua qhov nyuaj dua. Raws li kev kwv yees ntawm cov tsev kawm ntawv cuam tshuam: kuv lub teb chaws qhov kev thov hluav taws xob yuav nce mus txog 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 cov pa phem xoom hauv lub zog hluav taws xob. Yog tias lub chaw tsim hluav taws xob thee tau teeb tsa nrog CCUS, nws tuaj yeem ntes tau 90% ntawm cov pa phem carbon, ua rau nws yog cov thev naus laus zis tsim hluav taws xob qis-carbon. Daim ntawv thov CCUS yog txoj hauv kev tseem ceeb los paub txog qhov yooj ywm ntawm lub zog hluav taws xob. Hauv qhov no, qhov kev thov rau cov li qub los ntawm kev teeb tsa ntawm CCUS yuav nce ntxiv ntau, thiab qhov kev thov rau cov li qub hauv kev lag luam fais fab, tshwj xeeb tshaj yog kev lag luam fais fab thermal, yuav qhia txog kev loj hlob tshiab, uas tsim nyog rau kev saib xyuas ntawm cov tuam txhab lag luam valve.
C. Kev thov rau kev lag luam hlau thiab hlau yuav loj hlob tuaj
Kwv yees tias qhov kev thov kom txo qis kev tso pa tawm hauv xyoo 2030 yuav yog 200 lab tons txog 0.50 lab tons hauv ib xyoos. Nws tsim nyog sau tseg tias ntxiv rau kev siv thiab khaws cia cov pa roj carbon dioxide hauv kev lag luam hlau, nws kuj tseem siv tau ncaj qha rau hauv cov txheej txheem ua hlau. Kev siv tag nrho cov thev naus laus zis no tuaj yeem txo cov pa phem los ntawm 5% -10%. Los ntawm qhov kev xav no, qhov kev thov valve cuam tshuam hauv kev lag luam hlau yuav hloov pauv tshiab, thiab qhov kev thov yuav qhia txog kev loj hlob tseem ceeb.
D. Kev thov ntawm kev lag luam cement yuav loj hlob ntau heev
Kwv yees tias qhov kev thov txo qis kev tso pa tawm hauv xyoo 2030 yuav yog 100 lab tons txog 152 lab tons hauv ib xyoos, thiab qhov kev thov txo qis kev tso pa tawm hauv xyoo 2060 yuav yog 190 lab tons txog 210 lab tons hauv ib xyoos. Cov pa roj carbon dioxide uas tsim los ntawm kev lwj ntawm limestone hauv kev lag luam cement suav txog li 60% ntawm tag nrho cov pa roj tawm, yog li CCUS yog ib txoj hauv kev tsim nyog rau kev tshem tawm carbon ntawm kev lag luam cement.
E. Kev thov kom muaj zog hydrogen hauv kev lag luam yuav raug siv dav
Kev rho tawm cov hydrogen xiav los ntawm methane hauv cov roj ntuj yuav tsum tau siv ntau lub valve, vim tias lub zog raug ntes los ntawm cov txheej txheem ntawm CO2 tsim, kev ntes thiab khaws cia carbon (CCS) yog qhov tsim nyog, thiab kev xa thiab khaws cia yuav tsum tau siv ntau lub valve.
3. Cov lus qhia rau kev lag luam valve
CCUS yuav muaj qhov chaw dav rau kev txhim kho. Txawm hais tias nws ntsib ntau yam teeb meem, thaum kawg, CCUS yuav muaj qhov chaw dav rau kev txhim kho, uas tsis muaj lus nug. Kev lag luam valve yuav tsum tswj hwm kev nkag siab meej thiab kev npaj siab txaus rau qhov no. Nws raug pom zoo tias kev lag luam valve yuav tsum siv cov teb cuam tshuam nrog CCUS kev lag luam.
A. Koom tes nrog cov haujlwm qhia txog CCUS. Rau qhov project CCUS uas tab tom ua hauv Suav teb, cov tuam txhab lag luam valve yuav tsum koom tes nrog kev siv qhov project no hauv kev tshawb fawb thiab kev txhim kho thev naus laus zis thiab khoom, sau cov kev paub dhau los hauv cov txheej txheem koom nrog kev siv qhov project, thiab npaj txaus rau kev tsim khoom loj thiab kev sib phim valve tom ntej. Technology, peev xwm thiab cov khoom khaws cia.
B. Ua tib zoo saib xyuas qhov kev tsim kho tshiab ntawm CCUS tam sim no. Ua tib zoo saib xyuas kev lag luam fais fab thee uas siv cov thev naus laus zis ntes cov pa roj carbon hauv Suav teb, thiab kev lag luam roj av uas muaj chaw khaws cia hauv av kom siv CCUS project valves, thiab siv cov valves hauv cov chaw uas cov lag luam no nyob, xws li Ordos Basin thiab Junggar-Tuha Basin, uas yog cov chaw tsim cov thee tseem ceeb. Bohai Bay Basin thiab Pearl River Mouth Basin, uas yog cov chaw tsim roj thiab roj av tseem ceeb, tau tsim kev sib raug zoo nrog cov tuam txhab lag luam kom tau txais lub cib fim no.
C. Muab kev txhawb nqa nyiaj txiag rau kev tshawb fawb thiab kev tsim khoom ntawm CCUS project valves. Yuav kom ua tus thawj coj hauv kev tshawb fawb thiab kev txhim kho ntawm CCUS projects yav tom ntej, nws raug pom zoo kom cov tuam txhab lag luam tseg ib qho nyiaj txiag rau kev tshawb fawb thiab kev txhim kho, thiab muab kev txhawb nqa rau CCUS projects hauv kev tshawb fawb thiab kev txhim kho ntawm thev naus laus zis, kom tsim tau ib puag ncig zoo rau kev teeb tsa ntawm CCUS kev lag luam.
Hauv ntej, rau kev lag luam CCUS, nws raug pom zoo tiaslub valvekev lag luam nkag siab tag nrho txog kev hloov pauv tshiab hauv kev lag luam raws li txoj kev npaj "dual-carbon" thiab cov cib fim tshiab rau kev txhim kho uas los nrog nws, ua raws li lub sijhawm, thiab ua tiav kev txhim kho tshiab hauv kev lag luam!
