Munguva pfupi yapfuura, zvichitsigirwa nekudiwa kuri kuitwa neindasitiri, mitengo yakaderera yepeturu yemuno yakaunza kuwedzera kwechipiri mugore. Kudivi rekupa, zvinhu zvinotengwa nepeturu yemuno zvaive zvishoma munaGunyana, kuwanikwa kwezvinhu zvepeturu yemuno kwakawedzera zvishoma pane zvaitarisirwa, uye kunatswa kwesarufa yepeturu yecoke. Kudivi repamusoro, zvinhu zvepeturu yecoke ine sarufa shoma hazviwanzoitiki.
Munguva pfupi yapfuura, zvichitsigirwa nekudiwa kweindasitiri iri pasi, mutengo wepasi wepetcoke wakawedzera zvakanyanya kechipiri gore rino. Kudivi rekutengeswa kwepetroleum coke munaGunyana kwaive kushoma, uye kuwanikwa kwezviwanikwa zvepetroleum coke zvemuno hakuna kuwanikwa sezvaitarisirwa. Pamusoro pezvo, huwandu hwesarufa mupetroleum coke mukuchenesa kwazvino kwaive kwakakwira, uye zviwanikwa zvepetroleum coke zvine sulfur shoma zvaive zvisipo zvakanyanya. Kudivi rekudiwa, kudiwa kwecarbon yealuminium kwakasimba, uye nzvimbo dzekuchengetedza dzechando mudunhu rekumadokero dzakavhurwa imwe mushure meimwe. Nzvimbo yezvinhu zveanode yakatsigira zvakanyanya kudiwa kwepetroleum coke ine sulfur shoma, uye zviwanikwa zvakawanda zvepetroleum coke zvine sulfur shoma zvakapinda mumakambani ekugadzira graphite.
Chati yemitengo ye coke ine sarufa shoma muEast China muna 2021
Tichitarisa mitengo ye coke ine sulfur shoma muShandong neJiangsu, mutengo wekutanga kwa2021 uchava 1950-2050 yuan/tani. MunaKurume, nekuda kwemigumisiro miviri yekuderera kwehuwandu hwe petcoke yemuno uye kuwedzera kwekudiwa kwe downstream, mitengo ye petcoke yemuno yakaramba ichikwira zvakanyanya. Kunyanya, coke ine sulfur shoma yakatarisana nekugadziriswa kwemakambani. Mutengo wakakwira kusvika kuRMB 3,400-3500/tani, zvichisvika parekodhi. Kuwedzera kwerekodhi ne51% muzuva rimwe chete. Kubva muhafu yechipiri yegore, mitengo yakawedzera zvishoma nezvishoma pasi pekutsigira kudiwa muminda ye aluminium carbon ne steel carbon (carburizers, ordinal power graphite electrodes). Kubva muna Nyamavhuvhu, nekuda kwekukwira kwakatevedzana kwemitengo ye coke ine sulfur shoma muNortheast China, kudiwa kwe coke ine sulfur shoma mumunda we anode materials kwachinja kuenda kuEast China, izvo zvakakurumidzisa mwero wekuwedzera kwemitengo ye coke ine sulfur shoma muEast China kusvika pamwero wakati. Kubva vhiki rino, mutengo wecoke ine sarufa shoma muShandong neJiangsu wakwira kusvika pamadhora zviuru zvina nemazana mana ($4,000) patani, mutengo wakakwira zvikuru, unova kuwedzera kwe1950-2100 patani, kana kupfuura 100%, kubva pakutanga kwegore.
Mepu yekupararira kwenzvimbo dziri pasi perwizi dze coke ine sulfur yakaderera muEast China
Sezvatinoona kubva pamufananidzo uri pamusoro apa, kusvika vhiki rino, maererano nekugoverwa kwemafuta epetroleum coke mudunhu reShandong neJiangsu, kudiwa kwearuminiyamu kabhoni kwaive neanenge 38%, kudiwa kwemaelectrode asina kunaka kwaive 29%, uye kudiwa kwekabhoni yesimbi. Kwaive neanenge 22%, uye mamwe mabasa esimbi kwaive ne11%. Kunyangwe mutengo weparizvino wemafuta epetroleum coke asina sulfur munzvimbo iyi wakwira kusvika pamusoro pe4,000 yuan/ton, chikamu chearuminiyamu kabhoni chichiri pamusoro perunyorwa nekuda kwerutsigiro rwayo rwakasimba. Pamusoro pezvo, kudiwa kwese mumunda wemaelectrode asina kunaka kwakanaka, uye kugamuchirwa kwemutengo kwakasimba, nekudiwa kwayo kwaive ne29%. Kubva muhafu yechipiri yegore, kudiwa kweindasitiri yesimbi yemuno kwema recarburizer kwakadzikira, uye mwero wekushanda kwechoto chemagetsi wave pedyo ne60%, uye rutsigiro rwema graphite electrodes rwakaderera. Saka, tichitarisa, kudiwa kwemafuta epetroleum coke asina sulfur akawanda mumunda wemacarbon esimbi kwakadzikira zvakanyanya.
Pamwe chete, makambani ekugadzira petcoke ine sarufa shoma ePetroChina akakanganiswa nekugadzirwa kwemafuta emugungwa ane sarufa shoma kusvika pamwero wakati, uye kugadzirwa kwawo kwaderera. Parizvino, zviratidzo zve sarufa shoma muShandong neJiangsu zvakagadzikana uye huwandu hwesarufa huri mukati me0.5%, uye mhando yacho yakagadziridzwa zvakanyanya zvichienzaniswa negore rapfuura. Pamusoro pezvo, kudiwa munzvimbo dzakasiyana-siyana dziri pasi perwizi kuchawedzera zvisingadzivisike mune ramangwana, saka nekufamba kwenguva, kushomeka kwezviwanikwa zve petroleum coke ine sarufa shoma mudzimba kuchava kwakajairika.
