Vale thiab Pala xeev tsoomfwv tau muaj kev ua koob tsheej rau lub Plaub Hlis 6 los ua kev zoo siab rau qhov pib ntawm kev tsim kho thawj zaug kev lag luam cog qoob loo hauv Malaba, lub nroog nyob rau sab qab teb ntawm Pala xeev, Brazil.Tecnored, lub thev naus laus zis tshiab, tuaj yeem pab cov hlau thiab hlau kev lag luam decarbonize los ntawm kev siv biomass es tsis txhob siv hlau metallurgical thee los tsim ntsuab npua hlau thiab txo qis carbon emissions txog li 100%.Npua hlau tuaj yeem siv los tsim cov hlau.
Lub peev xwm tsim txhua xyoo ntawm ntsuab npua hlau nyob rau hauv cov nroj tsuag tshiab yuav pib mus txog 250000 tons, thiab nws yuav ncav cuag 500000 tons yav tom ntej.Cov nroj tsuag tau npaj yuav muab tso rau hauv kev ua haujlwm hauv 2025, nrog kev kwv yees peev ntawm kwv yees li 1.6 billion reais.
"Kev tsim kho ntawm tecnored lag luam kev lag luam cog yog ib kauj ruam tseem ceeb hauv kev hloov pauv ntawm kev lag luam mining.Nws yuav pab tau cov txheej txheem saw hlau ua ntau thiab ruaj khov.Qhov project Tecnored yog qhov tseem ceeb heev rau vale thiab thaj av uas qhov project nyob.Nws yuav txhim kho kev sib tw hauv cheeb tsam thiab pab thaj av kom muaj kev loj hlob ruaj khov. "Eduardo Bartolomeo, Vale tus thawj coj, tau hais.
Tecnored coj mus muag tshuaj cog yog nyob rau hauv thawj qhov chaw ntawm karajas npua hlau cog hauv Malaba muaj cheeb tsam.Raws li txoj haujlwm kev nce qib thiab kev tshawb fawb engineering, 2000 txoj haujlwm yuav tsum tau tsim nyob rau lub sijhawm siab tshaj plaws ntawm qhov project hauv kev tsim kho, thiab 400 txoj haujlwm ncaj qha thiab tsis ncaj yuav raug tsim nyob rau hauv lub sijhawm ua haujlwm.
Hais txog tecnored Technology
Tecnored rauv yog me dua li cov tsoos tawg rauv, thiab nws cov khoom siv raw tuaj yeem dav heev, los ntawm hlau ore hmoov, steel-ua slag rau ore dam sludge.
Nyob rau hauv cov nqe lus ntawm roj, tenored rauv siv tau carbonized biomass, xws li bagasse thiab Eucalyptus.Tecnored thev naus laus zis ua rau cov roj nyoos rau hauv compacts (me me compact blocks), thiab tom qab ntawd muab tso rau hauv qhov cub kom tsim cov npua ntsuab.Tecnored furnaces tuaj yeem siv cov thee metallurgical ua roj.Txij li thaum tecnored thev naus laus zis tau siv rau kev ua haujlwm loj rau thawj zaug, fossil fuels yuav raug siv rau hauv kev pib ua haujlwm ntawm cov nroj tsuag tshiab txhawm rau ntsuas kev ua haujlwm ntawm kev ua haujlwm.
"Peb yuav maj mam hloov cov thee nrog carbonized biomass kom txog thaum peb mus txog lub hom phiaj ntawm 100% siv biomass."Mr. Leonardo Caputo, CEO ntawm tecnored, tau hais.Flexibility hauv kev xaiv roj yuav txo tecnored cov nqi khiav hauj lwm txog li 15% piv nrog cov tsoos blast furnaces.
Tecnored tshuab tau tsim rau 35 xyoo.Nws tshem tawm cov coking thiab sintering txuas nyob rau hauv thaum ntxov theem ntawm steel ntau lawm, ob qho tib si emit ib tug loj npaum li cas ntawm tsev xog paj gases.
Txij li thaum siv tecnored rauv tsis tas yuav coking thiab sintering, peev ntawm Xingang cog tuaj yeem txuag tau txog li 15%.Tsis tas li ntawd, cov nroj tsuag tecnored yog tus kheej txaus nyob rau hauv lub zog efficiency, thiab tag nrho cov gases uas tsim nyob rau hauv lub smelting txheej txheem yog reused, ib co ntawm cov uas yog siv rau cogeneration.Nws tuaj yeem siv tsis yog tsuas yog cov khoom siv raw hauv cov txheej txheem smelting, tab sis kuj yog cov khoom lag luam hauv kev lag luam cement.
Vale tam sim no muaj kev ua qauv qhia cog nrog kev ntsuas txhua xyoo muaj peev xwm ntawm 75000 tons hauv pindamoniyangaba, Sao Paulo, Brazil.Lub tuam txhab ua cov txheej txheem kev txhim kho hauv cov nroj tsuag thiab sim nws txoj kev ua tau zoo thiab kev lag luam.
"Scope III" emission txo
Kev lag luam kev lag luam ntawm tecnored cog hauv Malaba qhia txog Vale txoj kev siv zog los muab cov kev daws teeb meem rau cov neeg siv khoom cog steel los pab lawv decarbonize lawv cov txheej txheem ntau lawm.
Xyoo 2020, Vale tau tshaj tawm lub hom phiaj ntawm kev txo qis net emissions ntawm "scope III" los ntawm 15% los ntawm 2035, ntawm uas nce mus txog 25% yuav ua tiav los ntawm cov khoom lag luam zoo thiab cov tswv yim thev naus laus zis tshiab suav nrog smelting ntsuab npua hlau.Emissions los ntawm kev lag luam steel tam sim no suav txog 94% ntawm Vale's "scope III" emissions.
Vale kuj tau tshaj tawm lwm lub hom phiaj txo qis qis, uas yog, kom ua tiav qhov ncaj qha thiab tsis ncaj qha net xoom emissions ("scope I" thiab "scope II") los ntawm 2050. Lub tuam txhab yuav nqis peev US $ 4 billion rau US $ 6 billion thiab nce kev rov qab los thiab tiv thaiv. thaj tsam hav zoov los ntawm 500000 hectares hauv Brazil.Vale tau ua haujlwm hauv Pala xeev tau ntau dua 40 xyoo.Lub tuam txhab yeej ib txwm txhawb nqa lub koom haum chicomendez rau kev txuag biodiversity (icmbio) los tiv thaiv rau rau thaj tsam ntawm karagas, uas yog hu ua "karagas mosaic".Lawv npog tag nrho ntawm 800000 hectares ntawm Amazon hav zoov, uas yog tsib npaug ntawm thaj tsam ntawm Sao Paulo thiab sib npaug rau Wuhan hauv Suav teb.
