Hurumende yenyika yeVale nePala yakaita mhemberero muna Kubvumbi 6 kupemberera kutanga kwekuvakwa kwekutanga tecnored commercial operation plant muMalaba, guta riri kumaodzanyemba kwakadziva kumabvazuva kwePala state, Brazil.Tecnored, innovative tekinoroji, inogona kubatsira simbi nesimbi indasitiri decarbonize nekushandisa biomass pachinzvimbo chemetallurgical marasha kugadzira girini yenguruve iron uye kuderedza kabhoni emissions inosvika zana%.Nguruve iron inogona kushandiswa kugadzira simbi.
Iyo yegore yekugadzira simba yegirini yenguruve simbi muchirimwa chitsva ichatanga kusvika 250000 matani, uye inogona kusvika 500000 matani mune ramangwana.Chirimwa ichi chakarongwa kuiswa mukushanda muna 2025, paine mari inofungidzirwa kuti inosvika bhiriyoni 1.6 reais.
“Kuvakwa kwe tecnored commercial operation plant idanho rakakosha mukusandura indasitiri yezvicherwa.Ichabatsira iyo nzira cheni kuti iwedzere uye inogadzikana.Tecnored purojekiti yakakosha zvikuru kune vale uye nharaunda iyo chirongwa chiripo.Ichavandudza kukwikwidza kwematunhu uye kubatsira dunhu kuwana budiriro inoenderera. "Eduardo Bartolomeo, mukuru weVale, akadaro.
Tecnored yekutengesa kemikari chirimwa chiri panzvimbo yekutanga yekarajas pig iron chirimwa muMalaba maindasitiri zone.Zvinoenderana nekufambira mberi kweprojekiti uye kutsvagisa kweinjiniya, mabasa mazana maviri anotarisirwa kugadzirwa munguva yepamusoro yeprojekiti padanho rekuvaka, uye mazana mana akananga uye asina kunanga mabasa anogona kugadzirwa mudanho rekushanda.
Nezve tecnored Technology
Tecnored furnace idiki pane yechinyakare blast furnace, uye huwandu hwayo hwezvigadzirwa zvinogona kuve zvakapamhama, kubva kusimbi ore poda, simbi-kugadzira slag kune ore dhamu dhamu.
Panyaya yehuni, tenored vira inogona kushandisa carbonized biomass, senge bagasse uye Eucalyptus.Tecnored tekinoroji inogadzira mafuta mbishi kuita ma compacts (madiki compact blocks), uye oaisa muchoto kuti abudise yegirini yenguruve iron.Tecnored furnaces inogona zvakare kushandisa marasha esimbi sehuni.Sezvo tecnored tekinoroji ichishandiswa pakukura kukuru kekutanga, mafuta efossil achashandiswa mukutanga kushanda kwechirimwa chitsva kuitira kuongorora kushanda kwekuita.
"Tichatsiva marasha zvishoma nezvishoma necarbonized biomass kudzamara tasvika pachinangwa chekushandisa 100% yebiomass."Mr. Leonardo Caputo, CEO we tecnored, akadaro.Kuchinjika mukusarudza mafuta kunodzikisa mitengo yekushanda kwe tecnored kusvika 15% zvichienzaniswa nevechinyakare kuputika kwevira.
Tecnored tekinoroji yakagadziridzwa kwemakore makumi matatu nemashanu.Inobvisa coking uye sintering links mukutanga kwekugadzirwa kwesimbi, izvo zvose zvinobudisa huwandu hwakawanda hwemagasi ekupisa.
Sezvo kushandiswa kwechoto che tecnored hakudi kubikira uye kunyura, kudyara kweXingang chirimwa kunogona kuchengetedza kusvika 15%.Mukuwedzera, iyo tecnored chirimwa inozvimiririra mukugadzirisa simba, uye magasi ese anogadzirwa mukunyungudutsa anoshandiswa zvakare, mamwe acho anoshandiswa pakubatana.Inogona kushandiswa kwete chete seyakasvibirira mukugadzira kunyungudutsa, asiwo seyakagadzirwa muindasitiri yesamende.
Vale parizvino ine simiti yekuratidzira ine chiyero chakayerwa chegore rematani e75000 mupindamoniyangaba, Sao Paulo, Brazil.Iyo kambani inoita budiriro yehunyanzvi muchirimwa uye inoedza kugona kwayo kwehunyanzvi uye kwehupfumi.
"Scope III" kuderedza emission
Kushanda kwekutengesa kwetecnored chirimwa muMalaba kunoratidza kuedza kwaVale kupa zvigadziriso zvehunyanzvi kune vatengi vechirimwa chesimbi kuti vavabatsire kubvisa kaboni maitiro avo ekugadzira.
Muna 2020, Vale akazivisa chinangwa chekudzikisa mambure e "scope III" ne15% ne2035, iyo inosvika ku25% ichawanikwa kuburikidza nemhando yepamusoro yezvigadzirwa zvemhando yepamusoro uye zvirongwa zvehunyanzvi zvehunyanzvi zvinosanganisira kunyungudutsa simbi yenguruve.Hutsi hunobva kuindasitiri yesimbi parizvino hunoita 94% ye“scope III” yaVale.
Vale akazivisawo chimwe chinangwa chekudzikisa emission, ndiko kuti, kuwana zvakananga uye zvisina kunanga net zero emissions ("scope I" uye "scope II") panosvika 2050. nzvimbo yesango ne500000 mahekita muBrazil.Vale anga achishanda mudunhu rePala kweanopfuura makore makumi mana.Kambani iyi yagara ichitsigira chicomendez Institute for biodiversity conservation (icmbio) kuchengetedza nzvimbo nhanhatu dziri mudunhu reKaragas, dzinodaidzwa kuti "karagas mosaic".Vanofukidza huwandu hwe800000 mahekita edondo reAmazon, iro rakapetwa kashanu nzvimbo yeSao Paulo uye yakaenzana neWuhan kuChina.
