Muva nje, kusekelwa yisidingo semboni esezansi, amanani entengo ephansi ye-petcoke yasekhaya alethe ukwanda kwesibili ngonyaka. Ngasohlangothini lokuhlinzekwa, ukungeniswa kwe-petcoke bekuncane ngoSepthemba, ukunikezwa kwezinsiza ze-petcoke zasekhaya kwehle kancane kunalokho obekulindelwe, kanye nokuhlungwa kwakamuva kokuqukethwe kwe-petroleum coke sulfur. Ngasohlangothini oluphezulu, izinsiza ze-petroleum coke ze-sulfur ephansi zimbalwa kakhulu.
Muva nje, ngenxa yesidingo semboni esezansi, intengo yasekhaya ye-petcoke ibangele ukwanda okukhulu okwesibili kulo nyaka. Ngasohlangothini lokuhlinzekwa, inani lokungeniswa kwe-petroleum coke ngoSepthemba lalilincane, futhi ukunikezwa kwezinsizakusebenza ze-petroleum coke zasekhaya akuzange kutholakale njengoba bekulindelekile. Ngaphezu kwalokho, okuqukethwe kwe-sulfur ye-petroleum coke ekuhlanzweni kwakamuva kwakuphezulu kakhulu, kanti izinsizakusebenza ze-petroleum coke ezine-sulfur ephansi zazintuleka kakhulu. Ngasohlangothini lokufunwa, isidingo se-carbon ye-aluminium sinamandla, futhi izindawo zokugcina zasebusika esifundeni esisentshonalanga zivuliwe ngokulandelana. Insimu yezinto ze-anode idlale ukusekela okukhulu kwesidingo se-petroleum coke ene-sulfur ephansi, futhi izinsizakusebenza ze-petroleum coke ezine-sulfur eningi kakhulu ziye zangena emabhizinisini e-graphite okwenziwa.
Ishadi lentengo ye-coke kaphethiloli ephansi-sulfur eMpumalanga China ngo-2021
Uma sibheka ukuthambekela kwentengo ye-coke kaphethiloli ene-sulfur ephansi eShandong naseJiangsu, intengo ekuqaleni kuka-2021 izoba yi-yuan/ton ka-1950-2050. NgoMashi, ngenxa yemiphumela emibili yokwehla kokuhlinzekwa kwe-petcoke yasekhaya kanye nokwanda kwesidingo esingezansi, amanani e-petcoke yasekhaya aqhubeka nokukhuphuka kakhulu. Ikakhulukazi, i-coke ene-sulfur ephansi ibhekane nokulungiswa okuthile kwezinkampani. Intengo ikhuphuke yaya ku-RMB 3,400-3500/ton, yafinyelela irekhodi. Ukwenyuka okurekhodiwe ngo-51% ngosuku olulodwa. Kusukela engxenyeni yesibili yonyaka, amanani akhuphuke kancane kancane ngaphansi kokusekelwa kwesidingo emikhakheni ye-aluminium carbon kanye ne-steel carbon (ama-carburizer, ama-electrode ajwayelekile e-graphite). Kusukela ngo-Agasti, ngenxa yokwanda okulandelanayo kwamanani e-coke kaphethiloli ene-sulfur ephansi eNyakatho-mpumalanga yeShayina, isidingo se-coke kaphethiloli ene-sulfur ephansi emkhakheni wezinto ze-anode sishintshele eMpumalanga yeShayina, okusheshise izinga lokwenyuka kwamanani e-coke kaphethiloli ene-sulfur ephansi eMpumalanga yeShayina ngezinga elithile. Kusukela kuleli sonto, intengo ye-coke kaphethiloli ene-sulfur ephansi eShandong naseJiangsu ikhuphuke yafinyelela ngaphezu kwama-yuan angu-4,000/ton, okuyirekhodi eliphezulu, okuwukwenyuka kwama-yuan angu-1950-2100/ton, noma ngaphezu kwama-100%, kusukela ekuqaleni konyaka.
Imephu yokusatshalaliswa kwezindawo ezingezansi komfula ze-coke esezingeni eliphezulu ye-sulfur e-East China
Njengoba kungabonakala esithombeni esingenhla, kusukela kuleli sonto, maqondana nokusatshalaliswa kwesidingo se-petroleum coke ezansi kwezifundazwe zaseShandong naseJiangsu, isidingo se-aluminium carbon sasingu-38%, isidingo sama-electrode angemihle sasingu-29%, kanye nesidingo se-carbon yensimbi. Singu-22%, kanti ezinye izinkambu zazingu-11%. Nakuba intengo yamanje ye-coke ye-petroleum ene-sulfur ephansi esifundeni ikhuphuke yaya ngaphezu kwama-yuan angu-4,000/ton, umkhakha we-carbon ye-aluminium usaphezulu ohlwini ngenxa yokusekelwa kwawo okuqinile. Ngaphezu kwalokho, isidingo sonke ensimini ye-electrode engemihle sihle, futhi ukwamukelwa kwentengo kunamandla kakhulu, kanti isidingo saso singu-29%. Kusukela engxenyeni yesibili yonyaka, isidingo semboni yensimbi yasekhaya sama-recarburizers sehlile, kanti izinga lokusebenza kwe-arc furnace kagesi selicishe libe ngu-60%, futhi ukwesekwa kwama-electrode e-graphite kubuthakathaka. Ngakho-ke, uma sikhuluma ngokuqhathaniswa, isidingo se-coke ye-petroleum ene-sulfur ephansi ensimini ye-carbon yensimbi sehlile kakhulu.
Sekukonke, amabhizinisi okukhiqiza ama-petcoke ane-sulfur ephansi asePetroChina athintwe ukukhiqizwa kukaphethiloli wasolwandle one-sulfur ephansi ngezinga elithile, futhi umkhiqizo wawo wehlile. Njengamanje, izinkomba ze-coke kaphethiloli ene-sulfur ephansi eShandong naseJiangsu zizinzile futhi okuqukethwe kwe-sulfur ngokuyisisekelo kugcinwa ngaphakathi kuka-0.5%, futhi ikhwalithi ithuthukiswe kakhulu uma kuqhathaniswa nonyaka odlule. Ngaphezu kwalokho, isidingo ezindaweni ezahlukahlukene ezingezansi sizokhula ngokunganciphi esikhathini esizayo, ngakho-ke ngokuhamba kwesikhathi, ukushoda kwezinsizakusebenza zasekhaya ze-coke kaphethiloli ene-sulfur ephansi kuzoba okuvamile.
