Urhulumente welizwe laseVale kunye nePala babambe umbhiyozo nge-6 ka-Epreli ukubhiyozela ukuqaliswa kokwakhiwa kweplanti yorhwebo lokuqala eMalaba, isixeko esikumazantsi-mpuma welizwe lasePala, eBrazil.I-Tecnored, iteknoloji entsha, inokunceda ishishini lentsimbi kunye nentsimbi likhuphe ikhabhoni ngokusebenzisa i-biomass endaweni yamalahle e-metallurgical ukuvelisa i-iron yehagu eluhlaza kunye nokunciphisa ukukhutshwa kwekhabhoni ukuya kuthi ga kwi-100%.Intsimbi yehagu ingasetyenziselwa ukuvelisa intsimbi.
Umthamo wonyaka wemveliso yentsimbi yehagu eluhlaza kwisityalo esitsha uya kuqala ukufikelela kwiitoni ezingama-250000, kwaye unokufikelela kwiitoni ezingama-500000 kwixesha elizayo.Lo mzimveliso ucetywe ukuba uqalise ukusebenza ngo-2025, notyalo-mali oluqikelelwa malunga ne-1.6 yeebhiliyoni zeereais.
“Ukwakhiwa komzi-mveliso we-tecnored worhwebo linyathelo elibalulekileyo kwinguqu yoshishino lwemigodi.Kuya kunceda ikhonkco lenkqubo ukuba libe ngakumbi kwaye lizinzile.Iprojekthi yeTecnored ibaluleke kakhulu kwiVale nakwingingqi apho iprojekthi ikhoyo.Iza kuphucula ukhuphiswano lwengingqi kwaye incede ummandla uphumeze uphuhliso oluzinzileyo.”U-Eduardo Bartolomeo, umphathi oyintloko kaVale, uthe.
Iplanti yeekhemikhali zeTecnored ibekwe kwindawo yokuqala yesityalo sentsimbi yehagu yekarajas kwindawo yoshishino yaseMalaba.Ngokwenkqubela yeprojekthi kunye nophando lobunjineli, imisebenzi engama-2000 elindeleke ukuba idalwe kwixesha leprojekthi ephezulu kwinqanaba lokwakha, kwaye imisebenzi engama-400 ethe ngqo nengathanga ngqo inokudalwa kwinqanaba lokusebenza.
Malunga neTecnored Technology
I-Tecnored furnace incinci kune-ore blast furnace, kwaye uluhlu lwayo lwemathiriyeli ekrwada lunokuba banzi kakhulu, ukusuka kumgubo wentsimbi, i-steel-making slag ukuya kwi-ore dam sludge.
Ngokubhekiselele kumafutha, i-furnace ene-tenored inokusebenzisa i-carbonized biomass, efana ne-bagasse kunye ne-Eucalyptus.Itekhnoloji yeTecnored yenza amafutha akrwada abe yi-compact (iibhloko ezincinci ezixineneyo), kwaye emva koko ziwafake eziko ukuvelisa intsimbi yehagu eluhlaza.Iziko le-Tecnored lingasebenzisa amalahle esinyithi njengamafutha.Kuba itekhnoloji ye-tecnored isetyenziselwa umsebenzi omkhulu okokuqala, izibaso zefosili ziya kusetyenziswa kumsebenzi wokuqala womatshini omtsha ukuze kuvavanywe ukusebenza komsebenzi.
"Siza kuthatha indawo yamalahle nge-carbonized biomass de sifikelele kwiinjongo zokusetyenziswa kwe-100% ye-biomass."UMnu Leonardo Caputo, i-CEO ye-tecnored, uthe.Ukuguquguquka ekukhetheni amafutha kuya kunciphisa iindleko zokusebenza kwe-tecnored ukuya kuthi ga kwi-15% xa kuthelekiswa neziko lemveli lokuqhushumba.
Itekhnoloji yeTecnored yaphuhliswa iminyaka engama-35.Iphelisa i-coking kunye ne-sintering links kwinqanaba lokuqala lokuvelisa isinyithi, zombini ezo zikhupha inani elikhulu le-greenhouse gases.
Ekubeni ukusetyenziswa kwe-furnace ye-tecnored ayifuni i-coking kunye ne-sintering, utyalo-mali lwe-Xingang plant lunokugcina ukuya kwi-15%.Ukongezelela, isityalo se-tecnored siyakwazi ukuzimela ekusebenzeni kwamandla, kwaye zonke iigesi eziveliswa kwinkqubo yokunyibilikisa ziphinda zisetyenziswe, ezinye zazo zisetyenziselwa ukudibanisa.Ayinakusetyenziswa kuphela njengezinto eziluhlaza kwinkqubo yokunyibilikisa, kodwa nanjengemveliso ephuma kushishino lwesamente.
I-Vale okwangoku inesityalo sokubonisa esinomthamo olinganisiweyo wonyaka weetoni ze-75000 kwi-pindamoniyangaba, eSao Paulo, eBrazil.Inkampani iqhuba uphuhliso lobugcisa kwiplanti kwaye ivavanya ukubanakho kobugcisa kunye noqoqosho.
Ukunciphisa ukukhutshwa kwe-"Scope III".
Umsebenzi worhwebo weplanti ye-tecnored e-Malaba ubonisa iinzame zikaVale zokubonelela ngezisombululo zobuchwepheshe kubathengi bezityalo zentsimbi ukubanceda ukuba bakhuphe inkqubo yabo yokuvelisa.
Kwi-2020, i-Vale ibhengeze injongo yokunciphisa ukukhutshwa kwe-net "scope III" nge-15% ngo-2035, apho ukuya kuthi ga kwi-25% iya kufezekiswa ngepotfoliyo yemveliso ephezulu kunye neenkqubo ezintsha zobuchwepheshe ezibandakanya ukunyibilikisa intsimbi yehagu eluhlaza.Izinto ezikhutshwayo ezivela kushishino lwentsimbi kungoku nje zibalelwa kuma-94% ezinto ezikhutshwa yiVale “scope III”.
UVale uphinde wabhengeza enye into ekujoliswe kuyo yokunciphisa i-emission, oko kukuthi, ukufikelela ngokuthe ngqo kunye nokungathanga ngqo kwi-zero emissions ("scope I" kunye "ne-scope II") ngo-2050. indawo yehlathi ngeehektare ezingama-500000 eBrazil.UVale usebenze kwiphondo lasePala ngaphezulu kweminyaka engama-40.Inkampani ibisoloko ixhasa iZiko leChicomendez loLondolozo lweBiodiversity (icmbio) ukukhusela oovimba abathandathu kwingingqi yeKaragas, ebizwa ngokuba yi "karagas mosaic".Bagubungela i-800000 yeehektare zehlathi lase-Amazon, eliphindwe kahlanu kwindawo yaseSao Paulo kwaye lilingana ne-Wuhan e-China.
