Ngo-2021, intengo ye-petroleum coke iqhubekile nokunyuka okuphezulu. NgoSepthemba, intengo ye-petroleum coke ibangele ukwanda okukhulu. Ushintsho lwentengo alunakuhlukaniswa noshintsho oluyisisekelo lokuhlinzekwa kanye nesidingo. Ngemuva kwalo mjikelezo, sibheke ukuthi isimo sinjani.
Umqondo ophelele onquma indlela yokunikezwa kanye nesidingo uncike emthethweni oyisisekelo: isitokwe esikhathini esifushane, inzuzo esikhathini esimaphakathi kanye nomthamo esikhathini eside. Ukuthambekela kokunikezwa kanye nesidingo kunquma indlela yentengo yemikhiqizo, ngakho ake sibheke indlela yentengo ye-petroleum coke. Isibalo 1 sibonisa indlela yentengo ye-petroleum coke, insalela kanye ne-Brent (amanani e-petroleum coke kanye nensalela wonke athathwe entengo ejwayelekile ye-Shandong Refinery). Intengo yensalela igcina indlela ehambisanayo nentengo kawoyela yamazwe ngamazwe i-Brent, kodwa indlela yenkambiso yentengo ye-petroleum coke kanye nensalela kanye nentengo kawoyela yamazwe ngamazwe i-Brent ayibonakali. Ingabe ukunikezwa okuqinile, okuqhutshwa yisidingo, noma ezinye izici ezizobona ukwanda okukhulu kwentengo ngo-2021?
Izimpahla ezikhona njengamanje, i-coke yasekhaya esusa ichweba, impahla yokuhlanza, isitshalo se-calcining esingezansi, impahla yesitshalo se-pigment ayikwazi ukuthola idatha enembile yempahla ngokuningiliziwe, ngakho-ke akunakuphethwa ngokuthi izinguquko zokuhlinzekwa kanye nesidingo zishintsha impahla, kodwa okwamanje amasampula ocwaningo, isampula kuya ekucwengisisweni, isibonelo, kusukela ekuqaleni kukaSepthemba kuya ekucwengisisweni kwamasheya abephansi, futhi aqhubeka ehla kancane, Akukho ukukhathala okukhulu ngenxa yokwenyuka kwentengo, okungukuthi, indawo yokuhlanza yamanje isesesigabeni sokugcina impahla.
Isibalo 2 senzuzo yokupheka ebambezelekile ngamashadi entengo ye-petroleum coke (inzuzo yokupheka ebambezelekile, amanani e-petroleum coke avela endaweni yaseShandong), amanani kawoyela amanje aphezulu, ukupheka okubambezelekile kunenzuzo elinganiselwe, kodwa kuhlanganiswe nesibalo 3 izinguquko zesivuno se-petroleum coke yasekhaya, inzuzo enkulu yokupheka okubambezelekile ayizange ibangele ukwanda kokukhiqizwa kwe-petroleum coke. Lokhu kuhlobene neqiniso lokuthi i-petroleum coke ingumkhiqizo ongaphansi onomkhiqizo omncane embonini yokucwenga kanye namakhemikhali. Ukuqala kanye nomthwalo weyunithi yokupheka ebambezelekile ngeke kulungiswe ngokuphelele yi-petroleum coke.
Isithombe 4 se-sulfur eshadini lentengo eligxile eShanghai, se-sulfur coke yasekhaya esetshenziswa kakhulu ekuqondeni kokugeleza kwe-aluminium ne-carbon, ngakho-ke thatha amanani amabili, isithombe 4 sibonisa ukunyakaza kwentengo okuhlobene phakathi komkhuba, ikakhulukazi ngo-2021, amanani akhuphukayo asekela i-electrolytic aluminium enterprise esebenzayo, i-chinalco, isibonelo, engxenyeni yokuqala yalo nyaka, i-chinalco izofinyelela imali engenayo eyizigidigidi, Ukwenyuka konyaka nonyaka kwama-yuan acishe abe yizigidigidi ezingama-40, inzuzo ehlanganisiwe ebangelwa abanikazi bamasheya ezinkampanini ezisohlwini (ezibizwa ngokuthi inzuzo ehlanganisiwe) ngama-yuan ayizigidigidi ezingu-3.075, okwenyuka izikhathi ezingu-85.
Ekuphetheni, amanani entengo kaphethiloli we-coke ka-2021 ayakhuphuka, amanani amaningi akhishwa ohlangothini lwesidingo, kanye namanani entengo kaphethiloli we-coke aphezulu, akwenzanga uhlangothi lokunikezwa ukuthi lwandise umkhiqizo, uhlangothi lwesidingo alukabonakali lubonakala lucacile, uhlangothi lokunikezwa esikhathini esizayo esiseduze noma ukuthi idivayisi iqala, kodwa ukungeniswa kwamanye amazwe kuvame ukuba ngaphandle kwesizini, ukwakhiwa kwedivayisi yokupheka ebambezelekile kungandisa ukunikezwa kanye nesidingo sokukhululeka kokungezwani kwamanje? Ngokuphathelene nesimo samanje, ngaphandle kokuthi uhlangothi lokunikezwa lubonakala lunenani elikhulu lokukhiqiza, noma isiqondiso sesidingo esingezansi sibonakala ukulungiswa okukhulu okufanele, ngaphandle kwalokho, ubudlelwano bokunikezwa kanye nesidingo sesikhathi samanje kunzima ukuba noshintsho olukhulu, intengo kaphethiloli we-coke nayo kunzima ukuba nokubuyiselwa emuva okukhulu.
