Tsis ntev los no, tus neeg sau xov xwm ntawm "Kev Tshawb Fawb Txog Kev Lag Luam Txhua Hnub" tau kawm tias Tuam Tshoj txoj kev lag luam steel carbon peak siv txoj kev npaj thiab carbon neutral technology roadmap tau pib ua zoo.Ntawm qhov tod tes, txoj kev npaj qhia txog qhov txo qis, kev tswj cov txheej txheem nruj, thiab ntxiv dag zog rau kev tswj kav kav dej, uas ncaj qha hais txog kev sib koom ua ke ntawm kev txo cov pa phem thiab txo qis carbon, thiab txhawb kev hloov pauv ntsuab ntawm kev lag luam thiab tib neeg.
Kev lag luam sab hauv tau hais tias txhawb nqa cov pa roj carbon ntau hauv kev lag luam hlau yog ib qho ntawm kaum "cov pa roj carbon peaking" ua.Rau kev lag luam steel, qhov no yog ob qho tib si lub sijhawm thiab kev sib tw.Kev lag luam steel yuav tsum tau ua tib zoo saib xyuas kev sib raug zoo ntawm kev txhim kho thiab txo qis emissions, tag nrho thiab ib nrab, luv luv thiab nruab nrab-rau-ntev.
Thaum Lub Peb Hlis Ntuj xyoo no, Tuam Tshoj Iron thiab Steel Association tau tshaj tawm lub hom phiaj thawj zaug ntawm "carbon ncov" thiab "carbon neutrality" hauv kev lag luam steel.Ua ntej xyoo 2025, kev lag luam hlau thiab hlau yuav ua tiav qhov kawg ntawm cov pa roj carbon emissions;los ntawm 2030, kev lag luam hlau thiab hlau yuav txo nws cov pa roj carbon monoxide los ntawm 30% los ntawm lub ncov, thiab nws xav tias carbon emissions yuav raug txo los ntawm 420 lab tons.Tag nrho cov emissions ntawm carbon dioxide, sulfur dioxide, nitrogen oxides, thiab tej yam teeb meem nyob rau hauv cov hlau thiab steel kev lag luam qeb ntawm cov saum toj kawg nkaus 3 nyob rau hauv kev lag luam sector, thiab nws yog ib qho tseem ceeb rau cov hlau thiab steel kev lag luam kom txo carbon emissions.
"Nws yog 'kab hauv qab' thiab 'kab liab' nruj me ntsis txwv tsis pub muaj peev xwm tsim tawm tshiab.Consolidating cov txiaj ntsig ntawm kev txo peev xwm tseem yog ib qho ntawm cov haujlwm tseem ceeb ntawm kev lag luam yav tom ntej. "Nws yog ib qho nyuaj rau txwv txoj kev loj hlob sai ntawm domestic steel ntau lawm, thiab peb yuav tsum "ob-pronged".Raws li keeb kwm yav dhau los tias tag nrho cov nyiaj tau poob qis heev, kev ua haujlwm qis qis qis tseem yog qhov pib tseem ceeb.
Tam sim no, ntau tshaj 230 lub tuam txhab steel thoob plaws lub teb chaws tau ua tiav lossis tab tom siv ultra-low emission retrofits nrog kwv yees li 650 lab tons ntawm crude steel muaj peev xwm.Txog rau thaum lub Kaum Hlis 2021, 26 lub tuam txhab steel hauv 6 lub xeev tau tshaj tawm, ntawm 19 lub tuam txhab tau tshaj tawm kev tshaj tawm kev lag luam, tsis muaj kev cuam tshuam, thiab kev thauj mus los huv si, thiab 7 lub tuam txhab tau tshaj tawm ib nrab.Txawm li cas los xij, tus naj npawb ntawm cov tuam txhab steel tshaj tawm tshaj tawm yog tsawg dua 5% ntawm tag nrho cov tuam txhab steel hauv lub tebchaws.
Tus neeg hais saum toj no tau taw qhia tias tam sim no, qee lub tuam txhab hlau tsis muaj kev nkag siab tsis txaus ntawm kev hloov pauv hloov pauv hloov pauv, thiab ntau lub tuam txhab tseem tos thiab saib, ua rau poob qis tom qab lub sijhawm.Tsis tas li ntawd, qee lub tuam txhab muaj kev nkag siab tsis txaus ntawm qhov nyuaj ntawm kev hloov pauv, siv cov thev naus laus zis desulfurization thiab denitrification tsis txaus, kev tsis sib haum xeeb, kev thauj mus los huv, kev tswj hwm ib puag ncig, kev saib xyuas hauv online thiab kev tswj hwm, thiab lwm yam, muaj ntau yam teeb meem.Tseem muaj kev ua ntawm cov tuam txhab ua cuav cov ntaub ntawv tsim tawm, ua ob phau ntawv, thiab ua pov thawj cov ntaub ntawv pov thawj emissions cuav.
"Nyob rau hauv lub neej yav tom ntej, ultra-low emissions yuav tsum tau siv nyob rau hauv tag nrho cov txheej txheem, tag nrho cov txheej txheem, thiab tag nrho lub neej voj voog."Tus neeg ntawd tau hais tias dhau los ntawm kev sau se, kev tiv thaiv ib puag ncig sib txawv, cov nqi dej sib txawv, thiab cov nqi hluav taws xob, lub tuam txhab yuav ntxiv txoj cai kom ua tiav cov kev hloov pauv qis qis dua.Txhawb kev siv zog.
Ntxiv rau qhov yooj yim "dual zog noj tswj", nws yuav tsom mus rau kev txhawb nqa ntsuab layout, kev txuag hluav taws xob thiab kev txhim kho kev siv hluav taws xob, kev siv hluav taws xob zoo thiab cov qauv txheej txheem, tsim lub voj voog kev lag luam kev lag luam, thiab siv cov thev naus laus zis los ntawm cov pa roj carbon tsawg.
Cov neeg uas tau hais los saum toj no tau hais tias txhawm rau ua kom tau txais ntsuab, qis-carbon thiab kev txhim kho zoo hauv kev lag luam steel, nws kuj yuav tsum tau ua kom zoo rau kev lag luam layout.Ua kom cov zis piv ntawm cov txheej txheem luv luv hluav taws xob rauv steelmaking, thiab daws qhov teeb meem ntawm kev siv hluav taws xob siab thiab siab emission ntawm cov txheej txheem ntev steelmaking.Optimize tus nqi qauv, optimize cov kev lag luam saw, thiab zoo heev txo tus naj npawb ntawm ywj siab sintering, ywj siab kub dov, thiab ywj siab coking lag luam.Ua kom zoo rau cov qauv siv hluav taws xob, siv lub zog huv los hloov cov hluav taws xob hluav taws xob hluav taws xob, tshem tawm cov tshuab hluav taws xob, thiab ua kom muaj feem ntawm hluav taws xob ntsuab.Raws li cov qauv kev thauj mus los, nce qhov kev faib ua feem ntawm kev thauj mus los huv ntawm cov khoom siv thiab cov khoom siv sab nraud ntawm lub Hoobkas, siv cov kev tsheb ciav hlau thiab cov dej hloov mus rau qhov nruab nrab thiab ntev, thiab txais yuav cov yeeb nkab txoj kev hauv tsev lossis lub zog tshiab tsheb rau luv luv thiab nruab nrab;tag nrho siv txoj siv sia, taug kev, thiab cov menyuam caij tsheb thauj mus los hauv lub Hoobkas kom loj tshaj txo cov tsheb thauj mus los hauv lub Hoobkas thiab tshem tawm cov kev thauj mus los thib ob ntawm cov khoom hauv lub hoobkas.
Tsis tas li ntawd, qhov tam sim no concentration ntawm kev lag luam steel tseem tsawg, thiab cov kauj ruam tom ntej yuav tsum yog kom muaj kev sib koom ua ke thiab rov tsim kho thiab sib koom ua ke thiab txhim kho cov peev txheej.Nyob rau tib lub sijhawm, ntxiv dag zog rau kev tiv thaiv cov peev txheej xws li hlau ore.
Kev txo cov pa roj carbon monoxide ntawm cov tuam txhab ua lag luam tau nrawm dua.Raws li Tuam Tshoj lub tuam txhab hlau loj tshaj plaws thiab tam sim no nyob rau hauv lub ntiaj teb cov khoom tsim tawm txhua xyoo, Baowu ntawm Tuam Tshoj tau qhia meej tias nws siv zog ua kom tiav cov pa roj carbon ntau hauv xyoo 2023, muaj peev xwm txo qis carbon los ntawm 30% hauv 2030, thiab txo nws cov pa roj carbon monoxide. emissions los ntawm 50% los ntawm lub ncov nyob rau hauv 2042. , Ua kom tiav carbon neutrality los ntawm 2050.
"Nyob rau xyoo 2020, Tuam Tshoj tus Baowu cov khoom siv roj av yuav ncav cuag 115 lab tons, faib hauv 17 lub hauv paus steel.Tuam Tshoj tus Baowu txoj kev tsim cov hlau ntev ntev rau ze li 94% ntawm tag nrho.Kev txo qis carbon emissions ua rau muaj kev sib tw hnyav dua rau Tuam Tshoj Baowu dua li nws cov phooj ywg."Tuam Tshoj Baowu Party Secretary thiab Thawj Tswj Hwm Chen Derong tau hais tias Tuam Tshoj Baowu ua tus thawj coj hauv kev ua tiav cov pa roj carbon nruab nrab.
"Xyoo tas los no peb ncaj qha nres Zhangang thawj qhov kev npaj tua hluav taws kub hnyiab, thiab npaj yuav ua kom cov pa roj carbon tsawg tsawg thiab siv cov txheej txheem ntawm hydrogen-based shaft furnace rau coke cub gas."Chen Derong tau hais tias, tsim kom muaj hydrogen-raws li lub qhov cub hluav taws xob ncaj qha txo cov txheej txheem hlau, cov txheej txheem steel smelting yuav tsum ua tiav zero carbon emissions.
Hegang Group npaj kom ua tiav cov pa roj carbon ntau hauv 2022, txo cov pa roj carbon monoxide ntau dua 10% los ntawm qhov siab tshaj plaws hauv xyoo 2025, txo cov pa roj carbon monoxide ntau dua 30% ntawm qhov siab tshaj plaws hauv xyoo 2030, thiab ua tiav cov pa roj carbon nruab nrab hauv xyoo 2050. Ansteel Group npaj rau Ua tiav qhov siab tshaj plaws hauv tag nrho cov pa roj carbon emissions los ntawm 2025 thiab kev ua tiav hauv kev lag luam ntawm cov khoom siv hluav taws xob tsawg-carbon metallurgical thev naus laus zis hauv xyoo 2030, thiab siv zog los txo tag nrho cov pa roj carbon emissions los ntawm 30% ntawm qhov siab tshaj plaws hauv xyoo 2035;txuas ntxiv txhim kho cov thev naus laus zis uas tsis tshua muaj carbon metallurgical thiab dhau los ua kuv lub teb chaws kev lag luam steel Thawj cov tuam txhab steel loj kom ua tiav cov pa roj carbon nruab nrab.
