Txhawm rau txhawm rau txhim kho cov nqi hluav taws xob, kev lag luam electrolytic aluminium txuag hluav taws xob thiab txo qis emissions li cas?
Thaum Lub Yim Hli 27, National Development thiab Reform Commission tau tshaj tawm "Daim Ntawv Ceeb Toom ntawm Kauj Ruam-by-Step Tus Nqi Hluav Taws Xob Txoj Cai rau Kev Lag Luam Electrolytic Aluminium", uas yog ib qho kev ua tiav ntawm lub teb chaws tus nqi ntsuab ntxiv thiab kev ua si tag nrho ntawm kev taw qhia ntawm cov nqi hluav taws xob. Cov kws tshuaj ntsuam tau hais tias kuv lub teb chaws qhov kev hloov pauv ntawm cov nqi hluav taws xob yuav ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev txuag hluav taws xob tas mus li thiab txo qis emission ntawm kuv lub teb chaws txoj kev lag luam electrolytic aluminium, txhim kho kev siv hluav taws xob zoo, thiab pab kom ua tiav lub hom phiaj ntawm carbon ncov thiab carbon neutrality.
Wang Xianwei, tus kws tshawb fawb ntawm Tuam Tshoj Securities Investment Futures Industrial Products Division, tau hais tias daim ntawv ceeb toom muaj kev cuam tshuam loj heev rau cov tuam txhab hluav taws xob electrolytic suav nrog: thawj, nce qib hluav taws xob nqi hluav taws xob thiab tus nqi nce nqi, thiab thib ob, txwv tsis pub siv cov nqi hluav taws xob nyiam rau kev lag luam electrolytic aluminium.
Tshwj xeeb tshaj yog, thawj lub ntsiab lus yog cais cov electrolytic aluminium kev lag luam tus nqi hluav taws xob theem raws li kev siv hluav taws xob AC ntawm molten aluminium. "Cov qauv kev faib tawm tam sim no yog 13,650 kWh ib tuj. Yuav luag txhua lub tuam txhab hluav taws xob hluav taws xob hauv tsev tuaj yeem ua tau raws li tus qauv no thiab yuav tsis muaj kev pheej hmoo ntawm tus nqi nce nyob rau lub sijhawm luv luv. Tus qauv rau 2023 yog 13,450 kWh, thiab tus qauv rau 2025 yog 13,300 kWh tsuas yog cov tuam txhab lag luam tam sim no. kev kho dua tshiab. " Wang Xianwei tau hais tias feem ntau cov tuam txhab yuav tsum tau ntsib kev tswj hwm thiab kev txhim kho thev naus laus zis yog tias lawv xav kom ncav cuag tus qauv. Tsis tas li ntawd, tsab ntawv ceeb toom txhawb nqa cov tuam txhab hluav taws xob electrolytic aluminium kom nce qib kev siv ntawm cov tsis muaj dej txuas ntxiv dua tshiab xws li cua zog thiab hluav taws xob photovoltaic, thiab txo tus nqi rau kev txhawb siab.
Lub ntsiab lus thib ob yuav muaj kev cuam tshuam loj rau feem ntau cov tuam txhab txhuas tam sim no, thiab qhov cuam tshuam ncaj qha yog qhov nce ntawm cov nqi hluav taws xob. "Nws tau nkag siab tias vim qhov kev poob mus ntev ntawm cov lag luam electrolytic aluminium hauv ob peb xyoos dhau los, feem ntau cov tuam txhab txhuas tau sib tham nrog tsoomfwv hauv nroog, cov phiaj xwm hluav taws xob thiab cov chaw tsim hluav taws xob kom tau txais cov nqi hluav taws xob zoo tshaj plaws. yav tom ntej, thiab cov nqi tsim khoom lag luam yuav nce ntxiv. " Wang Xianwei hais.
Gu Fengda, tus thawj coj ntawm lub chaw tshawb fawb thiab kev sab laj ntawm Guoxin Futures, tau hais tias kuv lub teb chaws txoj kev lag luam txhuas tau raug kev kub ntxhov kom ua tiav lub hom phiaj kom ncav cuag cov pa roj carbon ntau hauv 2025 ua ntej ntawm lub sijhawm. Los ntawm qhov kev xav ntawm lub zog noj cov qauv ntawm kev lag luam txhuas, thee yog lub zog tseem ceeb rau txhuas smelting thiab alumina refining hauv Suav teb, suav txog 85% ntawm txhuas smelting zog thiab 87% ntawm alumina refining zog. Cov khoom siv raw khoom siv los ntawm kev khawb av mus rau kev xa khoom suav rau 22% ntawm tag nrho cov tsev cog khoom tso pa tawm ntawm thawj aluminium, ntawm cov thee suav rau 68% ntawm alumina refinery zog mov. Kev tsim tawm ntawm ib tuj ntawm electrolytic aluminium yuav tsim qhov nruab nrab ntawm 12 tons ntawm carbon emissions.
Los ntawm qhov kev xav ntawm kev siv hluav taws xob hauv kev lag luam txhuas thoob ntiaj teb, Tuam Tshoj cov khoom siv hluav taws xob electrolytic aluminium suav txog li 55% -60% ntawm lub ntiaj teb tag nrho cov khoom tsim tawm, thiab tau tuav txoj haujlwm ntawm lub ntiaj teb loj tshaj plaws electrolytic aluminium tsim thiab cov neeg siv khoom ntau xyoo. Txawm li cas los xij, vim yog lub zog siv hluav taws xob ntau ntawm kev lag luam txhuas Nws kuj tso siab rau cov thee thiab lwm yam khoom siv los ua raw khoom rau kev tsim hluav taws xob. Los ntawm cov ntaub ntawv pom, kwv yees li 70% ntawm cov emissions los ntawm lub ntiaj teb aluminium ntau lawm los ntawm Tuam Tshoj. "Yog li ntawd, raws li lub cav tseem ceeb rau kev txhawb nqa lub ntiaj teb kev siv txhuas mus ntev, Tuam Tshoj txoj kev lag luam txhuas yuav muaj cov dej num hnyav hauv kev hloov kho hluav taws xob thaum lub sij hawm 14th Tsib-Xyoo Plan lub sij hawm. Tshwj xeeb, kev sim ntawm European carbon kev lag luam tariffs yog maj mam nce mus, ntsib lub complex thoob ntiaj teb kev nom kev tswv kev lag luam. sib txawv thiab qhov kev sim hnyav lawv ntsib. " Gu Fengda hais tias.
Wang Xianwei tau taw qhia tias nyob rau hauv keeb kwm yav dhau los ntawm kev tswj hwm kev siv hluav taws xob thiab cov pa roj carbon dual, electrolytic aluminium lag luam, ib qho ntawm kev siv hluav taws xob siab, yuav tsum tau ntsib kev hloov kho lub zog. Daim ntawv ceeb toom yog qhov zoo rau kev txhawb nqa kev lag luam kom tsis tu ncua kev nqis peev hauv kev hloov pauv thev naus laus zis, tsis tu ncua kev txhim kho hluav taws xob thiab txo qis carbon emissions. Rau cov lag luam, txawm hais tias lawv yuav ntsib cov nqi nce hauv lub sijhawm luv luv, nyob rau lub sijhawm ntev nws yuav pab txhawb kev hloov pauv thiab hloov kho dua tshiab thiab txhawb kev noj qab haus huv thiab kev loj hlob mus ntev ntawm kev lag luam.
Nws tau nkag siab tias qhov kev ua tiav thaum ntxov ntawm cov nqi hluav taws xob sib txawv hauv kev lag luam electrolytic aluminium tau ua tiav cov txiaj ntsig, thiab cov txheej txheem hluav taws xob theem hluav taws xob tau siv txij li xyoo 2013. Los ntawm qhov kev xav ntawm kev siv cov txiaj ntsig, txoj cai sib txawv ntawm cov nqi hluav taws xob tau ua lub luag haujlwm zoo hauv kev txhawb nqa electrolytic aluminium kev lag luam los daws cov peev txheej ntau dhau, txhawb nqa kev lag luam kev loj hlob ntawm tag nrho cov kev lag luam, kev txhim kho kev lag luam thiab kev lag luam. tag nrho lub zog efficiency theem. Tsav los ntawm kev ua tau zoo ntawm cov cai thiab kev txhawb siab endogenous ntawm cov lag luam, kev siv hluav taws xob ntawm electrolytic aluminium kev lag luam tau poob rau xyoo tas los no. Kev siv hluav taws xob AC tag nrho ib tuj ntawm txhuas thiab txhuas ingots tau poob los ntawm 14,795 kWh hauv 2004 mus rau 13,543 kWh hauv 2020, txo qis dua 1,200. Kilowatt teev.
Qhov kev hloov kho txoj cai no hloov mus rau qhov kev txhim kho tiag tiag ntawm kev lag luam, suav nrog kev sib raug zoo ntawm kev txuag hluav taws xob hauv cov txheej txheem tsim khoom thiab kev siv hluav taws xob hauv kev tiv thaiv ib puag ncig kev hloov pauv, thiab ua tau raws li qhov yuav tsum tau ua ntawm ob lub hom phiaj carbon. Gu Fengda tau hais tias tom qab ntau xyoo ntawm kev ntxuav thiab kho cov kev lag luam electrolytic aluminium, kev hloov kho vaj huam sib luag tau txhawb kev tsim lub qab nthab rau cov khoom siv hluav taws xob electrolytic aluminium thiab daws qhov teeb meem loj tshaj plaws los ntawm kev tsis sib haum xeeb ntawm kev tsim cov peev txheej uas tau cuam tshuam kev lag luam rau ntau xyoo. Txij thaum ntawd los, los ntawm kev txhim kho txuas ntxiv ntawm kev tiv thaiv ib puag ncig thiab thev naus laus zis Nws yog qhov yuav tsum tau los txhawb kev hloov pauv thiab kho dua tshiab ntawm kuv lub teb chaws txoj kev lag luam electrolytic aluminium.
"Thiab nrog kev tawg ntawm kev thov hauv thaj tsam ntawm lub zog tshiab thiab cov txheej txheem tshiab thiab cov kev xav tau ntawm kev hloov pauv ntawm lub zog ntsuab raws li lub hom phiaj 'dual-carbon', cov khoom siv thiab kev xav tau kev loj hlob ntawm cov hlau tsis muaj hlau nyob hauv Suav teb yuav sib txawv rau yav tom ntej, thiab feem ntau ntawm cov hlau tsis muaj hlau yuav ntsib kev txwv, uas cuam tshuam nrog lub zog ntsuab kiv puag ncig. cobalt thiab lithium yuav txhawb ntxiv. " Gu Fengda ntseeg hais tias kev lag luam txhuas, raws li thaj chaw uas muaj cov pa roj carbon ntau hauv kev lag luam hlau tsis muaj hlau, yuav muaj tseeb ua kom nrawm nrawm ntawm kev hloov pauv ntsuab thiab cov pa roj carbon tsawg hauv tsib xyoos tom ntej. Kev tswj cov peev txheej tsim tau zoo, txhim kho cov qauv hluav taws xob zoo, tsim kho cov thev naus laus zis uas tsis muaj cov pa roj carbon monoxide, thiab nce kev siv cov khoom seem ntawm txhuas yog txoj hauv kev tseem ceeb rau kev lag luam txhuas kom ua tiav cov pa roj carbon ntau. Kev siv cov kev ntsuas kev lag luam xws li cov pa roj carbon emission trading mechanisms tseem yuav ua rau ntsuab, qis-carbon thiab kev loj hlob ntawm kev lag luam txhuas. Ua lub luag haujlwm tseem ceeb. Nrog rau ntau yam kev ntsuas ib txhij, kev lag luam txhuas yuav ua rau muaj kev hloov pauv keeb kwm thiab kev loj hlob ntawm "kev txo qis, ntim tswj, thiab kev hloov kho tus nqi".
