Kusukela ngo-2018 kuya ku-2022, umthamo wamayunithi okupheka aphuzile eShayina waba nomkhuba wokukhula kuqala bese wehla, kanti umthamo wamayunithi okupheka aphuzile eShayina wabonisa umkhuba wokukhula unyaka nonyaka ngaphambi kuka-2019. Ekupheleni kuka-2022, umthamo wamayunithi okupheka aphuzile eShayina wawungaba ngamathani ayizigidi ezingu-149.15, kanti amanye amayunithi ayesedluliselwe futhi aqaliswa ukusebenza. Ngomhlaka-6 Novemba, ukudla okuyinhloko kwamathani ayizigidi ezimbili ngonyaka ophuzile we-Shenghong Refining and Chemical Integration Project (Shenghong Refining and Chemical) kwaphumelela futhi kwakhiqiza imikhiqizo efanelekile. Umthamo weyunithi yokupheka ephuzile eMpumalanga China waqhubeka nokukhula.
Ukusetshenziswa kwe-coke kaphethiloli yasekhaya kubonise ukwenyuka kusukela ngo-2018 kuya ku-2022, kanti ukusetshenziswa kwe-coke kaphethiloli yasekhaya kuhlale kungaphezu kwamathani ayizigidi ezingama-40 kusukela ngo-2021 kuya ku-2022. Ngo-2021, isidingo esiphansi sanda kakhulu futhi izinga lokukhula kokusetshenziswa lakhuphuka. Kodwa-ke, ngo-2022, amanye amabhizinisi aphansi ayeqaphile ekuthengeni ngenxa yomthelela wobhubhane, futhi izinga lokukhula kokusetshenziswa kwe-coke kaphethiloli lehla kancane laya cishe ku-0.7%.
Emkhakheni we-anode ebhakiwe kusengaphambili, kube nomkhuba okhulayo eminyakeni emihlanu edlule. Ngakolunye uhlangothi, isidingo sasekhaya sikhulile, kanti ngakolunye uhlangothi, ukuthunyelwa kwamanye amazwe kwe-anode ebhakiwe kusengaphambili nakho kubonise umkhuba okhulayo. Emkhakheni we-graphite electrode, ukuguqulwa kohlangothi lokuhlinzekwa kusukela ngo-2018 kuya ku-2019 kusafudumele, futhi isidingo se-graphite electrode sihle. Kodwa-ke, njengoba imakethe yensimbi ibuthakathaka, inzuzo yokwenza insimbi yesithando sikagesi iyanyamalala, isidingo se-graphite electrode sincipha kakhulu. Emkhakheni we-carburizing agent, ukusetshenziswa kwe-petroleum coke bekulokhu kuzinzile eminyakeni yamuva nje, kodwa ngo-2022, ukusetshenziswa kwe-petroleum coke kuzokhula kakhulu ngenxa yokwanda kwe-carburizing agent njengomkhiqizo ongaphansi kwe-graphitization. Isidingo se-petroleum coke ensimini kaphethiloli sincike kakhulu ekwehlukeni kwentengo phakathi kwamalahle ne-petroleum, ngakho-ke siyashintshashintsha kakhulu. Ngo-2022, intengo ye-petroleum coke izohlala iphezulu, futhi inzuzo yentengo yamalahle izokhula, ngakho ukusetshenziswa kwe-petroleum coke kuzoncipha. Imakethe yensimbi ye-silicon ne-silicon carbide eminyakeni emibili edlule inhle, futhi ukusetshenziswa kwayo konke kuyanda, kodwa ngo-2022, ibuthakathaka kunonyaka odlule, futhi ukusetshenziswa kwe-petroleum coke kwehla kancane. Insimu yezinto ezisetshenziswa yi-anode, esekelwa yinqubomgomo kazwelonke, ibilokhu ikhula unyaka nonyaka eminyakeni yamuva. Ngokuphathelene nokuthumela ngaphandle i-calcined char, ngokwanda kwesidingo sasekhaya kanye nenzuzo yasekhaya ephezulu, ibhizinisi lokuthumela ngaphandle i-calcined char linciphile.
Isibikezelo semakethe yesikhathi esizayo:
Kusukela ngo-2023, isidingo semboni ye-petroleum coke yasekhaya singase sikhule kakhulu. Njengoba ukwanda noma ukususwa kwamandla athile okuhlanza, eminyakeni emihlanu ezayo, amandla okukhiqiza ngonyaka ka-2024 azophakama bese ehla abe sesimweni esizinzile, futhi amandla okukhiqiza ngonyaka ka-2027 kulindeleke ukuthi afinyelele amathani ayizigidi ezingu-149.6 ngonyaka. Ngesikhathi esifanayo, ngokwandiswa okusheshayo kwamandla okukhiqiza izinto ze-anode nezinye izimboni, isidingo sifinyelele ukuphakama okungakaze kubonwe ngaphambili. Kulindeleke ukuthi isidingo sasekhaya semboni ye-petroleum coke sizogcina ukuguquguquka kwaminyaka yonke kwamathani ayizigidi ezingu-41 eminyakeni emihlanu ezayo.
Ngokuphathelene nemakethe yokugcina yesidingo, ukuhweba jikelele kuhle, ukusetshenziswa kwezinto ze-anode kanye nensimu ye-graphitization kuyaqhubeka nokukhula, isidingo sensimbi semakethe ye-aluminium carbon sinamandla, ingxenye ye-coke engenisiwe ingena emakethe ye-carbon ukuze yengeze ukunikezwa, kanti imakethe ye-petroleum coke isalokhu iveza isimo somdlalo wesidingo sokunikezwa.
Isikhathi sokuthunyelwe: Novemba-15-2022
