Uhulumeni wesifunda sase-Vale nowasePala wenze umgubho ngo-Ephreli 6 ukugubha ukuqaliswa kokwakhiwa kwesikhungo sokuqala sokusebenza kwezentengiselwano eMalaba, idolobha eliseningizimu-mpumalanga yesifunda sasePala, eBrazil.I-Tecnored, ubuchwepheshe obusha, bungasiza imboni yensimbi nensimbi ikhiphe ikhabhoni ngokusebenzisa i-biomass esikhundleni samalahle e-metallurgical ukukhiqiza insimbi yengulube eluhlaza kanye nokunciphisa ukukhishwa kwekhabhoni kufika ku-100%.I-pig iron ingasetshenziselwa ukukhiqiza insimbi.
Umthamo wonyaka wokukhiqiza we-iron yengulube eluhlaza esitshalweni esisha uzoqale ufinyelele amathani angu-250000, futhi ungase ufinyelele amathani angu-500000 esikhathini esizayo.Lesi sikhungo kuhlelwe ukuthi siqale ukusebenza ngo-2025, ngokutshalwa kwezimali okulinganiselwa ku-1.6 billion reais.
“Ukwakhiwa kwesikhungo se-tecnored commercial operation kuyisinyathelo esibalulekile ekuguquleni imboni yezimayini.Kuzosiza uchungechunge lwezinqubo ukuthi luqhubeke luzinzile.Iphrojekthi ye-Tecnored ibaluleke kakhulu ku-vale nesifunda lapho iphrojekthi itholakala khona.Izokwenza ngcono ukuncintisana kwesifunda futhi isize isifunda sifinyelele intuthuko esimeme.”U-Eduardo Bartolomeo, oyisikhulu esiphezulu sikaVale, uthe.
I-Tecnored commercial chemical plant itholakala endaweni yokuqala ye-karajas pig iron plant e-Malaba industrial zone.Ngokwenqubekelaphambili yephrojekthi kanye nocwaningo lobunjiniyela, imisebenzi engu-2000 okulindeleke ukuthi idalwe esikhathini esiphezulu sephrojekthi esigabeni sokwakha, kanti imisebenzi eqondile nengaqondile engama-400 ingase idalwe esigabeni sokusebenza.
Mayelana neTecnored Technology
Isithando somlilo se-Tecnored sincane kakhulu kunesithando somlilo esivamile, futhi ububanzi baso bezinto ezingavuthiwe zingaba banzi kakhulu, kusukela kumpushana wensimbi, i-steel-making slag kuya kudaka lwedamu lensimbi.
Mayelana nophethiloli, isithando somlilo esine-tenored singasebenzisa i-carbonized biomass, njenge-bagasse ne-Eucalyptus.Ubuchwepheshe be-Tecnored benza amafutha aluhlaza abe ama-compact (amabhulokhi amancane ahlangene), bese ewafaka esithandweni ukuze akhiqize insimbi yengulube eluhlaza.Amalahle e-Tecnored angasebenzisa namalahle e-metallurgical njengophethiloli.Njengoba ubuchwepheshe be-tecnored busetshenziselwa ukusebenza ngezinga elikhulu ngokokuqala ngqá, izibaso ezimbiwa phansi zizosetshenziswa ekuqaleni kokusebenza kwesikhungo esisha ukuze kuhlolwe ukusebenza komsebenzi.
"Kancane kancane sizofaka i-carbonized biomass esikhundleni samalahle size sifinyelele umgomo wokusebenzisa i-biomass ngo-100%.UMnu Leonardo Caputo, oyi-CEO ye-tecnored, uthe.Ukuvumelana nezimo ekukhetheni uphethiloli kuzonciphisa izindleko zokusebenza ze-tecnored kufika ku-15% uma kuqhathaniswa neziko elivamile lomlilo.
Ubuchwepheshe be-Tecnored buye bathuthukiswa iminyaka engu-35.Iqeda izixhumanisi ze-coking kanye ne-sintering esigabeni sokuqala sokukhiqizwa kwensimbi, kokubili okukhipha inani elikhulu lamagesi abamba ukushisa.
Njengoba ukusetshenziswa kwesithando somlilo se-tecnored kungadingi ukuphekwa nokucwiliswa, ukutshalwa kwezimali kwesitshalo se-Xingang kungonga kufikela ku-15%.Ngaphezu kwalokho, isitshalo se-tecnored siyakwazi ukuzimela ngokusebenza kahle kwamandla, futhi wonke amagesi akhiqizwa ohlelweni lokuncibilikisa aphinde asetshenziswe, amanye awo asetshenziselwa ukuhlangana.Ingasetshenziswa hhayi kuphela njengempahla eluhlaza ohlelweni lokuncibilikisa, kodwa futhi njengomkhiqizo ovela embonini kasimende.
I-Vale njengamanje inendawo yokubonisa enesilinganiso sonyaka esingamathani angama-75000 e-pindamoniyangaba, eSao Paulo, eBrazil.Inkampani yenza ukuthuthukiswa kwezobuchwepheshe embonini futhi ihlola ukuthi kungenzeka yini ukusebenza kwayo kwezobuchwepheshe nezomnotho.
Ukuncishiswa kokukhishwa kwe-“Scope III”
Ukusebenza kwezentengiselwano kwemboni ye-tecnored e-Malaba kukhombisa imizamo ka-Vale yokuhlinzeka ngezixazululo zobuchwepheshe kumakhasimende emishini yensimbi ukuze awasize akhiphe inqubo yawo yokukhiqiza.
Ngo-2020, u-Vale wamemezela umgomo wokunciphisa ukukhishwa kwenetha kwe-"scope III" ngo-15% ngo-2035, okuzofinyelela ku-25% kuzozuzwa ngephothifoliyo yomkhiqizo wekhwalithi ephezulu kanye nezinhlelo ezintsha zobuchwepheshe ezihlanganisa ukuncibilikisa insimbi yengulube eluhlaza.Ikhabhoni ephuma embonini yensimbi njengamanje yenza ama-94% okukhishwa kwe-Vale “scope III”.
U-Vale uphinde wamemezela enye impokophelo yokunciphisa ukungcola, okungukuthi, ukuzuza ukukhishwa kwe-zero okuqondile nokungaqondile (“scope I” kanye “ne-scope II”) ngo-2050. Le nkampani izotshala ama-US $4 wezigidigidi kuya ku-US $6 wezigidigidi futhi yandise okubuyiselwe futhi okuvikelwe. indawo yehlathi ngamahektha angama-500000 eBrazil.UVale useneminyaka engaphezu kwengu-40 esebenza esifundazweni sasePala.Le nkampani ibilokhu isekela i-chicomendez Institute for biodiversity conservation (icmbio) ukuze ivikele izindawo eziyiziqiwi eziyisithupha esifundeni se-karagas, ezibizwa nge-“karagas mosaic”.Bahlanganisa isamba esingamahektha angu-800000 ehlathi lase-Amazon, eliphindwe kahlanu endaweni yaseSao Paulo futhi elilingana neWuhan eChina.
