Kutshanje, ngenxa yemfuno yeshishini elisezantsi, amaxabiso aphantsi e-petcoke asekhaya aqalise ukunyuka okwesibini kunyaka. Kwicala lokubonelela, ukungeniswa kwe-petcoke bekuncinci ngoSeptemba, ukunikezelwa kwezixhobo ze-petcoke zasekhaya kuye kwabuya ngaphantsi kunokuba bekulindelwe, kwaye ukucocwa kwakutshanje komxholo wesulfure we-petroleum coke. Kwicala eliphezulu, izixhobo ze-petroleum coke ezine-sulfur ephantsi zinqabile kakhulu.
Kutshanje, ngenxa yemfuno yeshishini elisezantsi, ixabiso le-petcoke lasekhaya libangele ukwanda okukhulu okwesibini kulo nyaka. Kwicala lokubonelela, umthamo we-petroleum coke yokungenisa ngoSeptemba wawumncinane, kwaye ukunikezelwa kwezixhobo ze-petroleum coke zasekhaya akuzange kubuyiselwe njengoko bekulindelwe. Ukongeza, umxholo wesalfure we-petroleum coke ekucocweni kwakutshanje wawuphezulu, kwaye izixhobo ze-petroleum coke ze-sulfur ezisezantsi zazinqongophele kakhulu. Kwicala lemfuno, imfuno yekhabhoni ye-aluminium inamandla, kwaye iindawo zokugcina zasebusika kummandla wasentshona zivuliwe enye emva kwenye. Intsimi yezinto ze-anode idlale inkxaso enamandla kwimfuno ye-petroleum coke ye-sulfur esezantsi, kwaye izixhobo ze-petroleum coke ezingakumbi ze-sulfur ezisezantsi ziye zangena kumashishini e-graphite yokwenziwa.
Itshathi yamaxabiso e-coke ye-petroleum ene-sulfur ephantsi eMpuma China ngo-2021
Xa sijonga indlela ethengiswa ngayo i-petroleum coke ene-sulfur ephantsi eShandong naseJiangsu, ixabiso ekuqaleni kuka-2021 liza kuba yi-1950-2050 yuan/ton. NgoMatshi, ngenxa yeziphumo ezimbini zokwehla kobonelelo lwe-petcoke yasekhaya kunye nokunyuka kwemfuno esezantsi, amaxabiso e-petcoke yasekhaya aqhubekile nokunyuka kakhulu. Ngokukodwa, i-low-sulfur coke ijongene notshintsho oluthile kwiinkampani. Ixabiso lenyuke laya kwi-RMB 3,400-3500/ton, lafikelela kwirekhodi. Ukunyuka kwerekhodi ngama-51% ngosuku olunye. Ukususela kwisiqingatha sesibini sonyaka, amaxabiso aye anda kancinci kancinci phantsi kwenkxaso yemfuno kwiindawo ze-aluminium carbon kunye ne-steel carbon (ii-carburizer, ii-electrodes zamandla aqhelekileyo ze-graphite). Ukususela ngo-Agasti, ngenxa yokunyuka ngokulandelelana kwamaxabiso e-petroleum coke ene-sulfur ephantsi eMantla-mpuma eTshayina, imfuno ye-low-sulfur petroleum coke kwicandelo lezinto ze-anode itshintshele eMpuma eTshayina, nto leyo eye yakhawulezisa izinga lokunyuka kwamaxabiso e-low-sulfur petroleum coke eMpuma eTshayina ukuya kwinqanaba elithile. Ukusukela kule veki, ixabiso le-petroleum coke ene-sulfur ephantsi eShandong naseJiangsu linyuke laya kutsho ngaphezulu kwe-4,000 yuan/ton, irekhodi eliphezulu, elinyuka ukusuka kwi-1950-2100 yuan/ton, okanye ngaphezulu kwe-100%, ukususela ekuqaleni konyaka.
Imephu yokusasazwa kweendawo ezisezantsi ze-coke ekumgangatho ophezulu ye-sulfur eMpuma China
Njengoko kunokubonwa kulo mfanekiso ungentla, ukusukela kule veki, ngokwemfuno ye-petroleum coke esezantsi kwiphondo laseShandong naseJiangsu, imfuno ye-aluminium carbon ibimalunga ne-38%, imfuno ye-electrodes ezingezizo ezibalelwa kwi-29%, kunye nemfuno ye-carbon yentsimbi. Ibimalunga ne-22%, kwaye ezinye iindawo ziyi-11%. Nangona ixabiso langoku le-petroleum coke enesi-sulfur esisezantsi kulo mmandla linyuke laya ngaphezulu kwe-4,000 yuan/ton, icandelo le-aluminium carbon lisaphambili kuluhlu ngenxa yenkxaso yalo enamandla. Ukongeza, imfuno iyonke kwintsimi ye-electrode engezizo ilungile, kwaye ukwamkelwa kwexabiso kunamandla, kunye nemfuno yayo ibimalunga ne-29%. Ukususela kwisiqingatha sesibini sonyaka, imfuno yeshishini lentsimbi yasekhaya yee-recarburizers yehlile, kwaye izinga lokusebenza kwe-electrical arc furnace lijikeleze malunga ne-60%, kwaye inkxaso ye-graphite electrodes ibuthathaka. Ke ngoko, xa sithetha, imfuno ye-petroleum coke enesi-sulfur esisezantsi kwintsimi ye-carbon yentsimbi yehlile kakhulu.
Lilonke, amashishini emveliso ye-petcoke e-sulfur ephantsi ePetroChina achatshazelwe kukuveliswa kwepetroli yaselwandle e-sulfur ephantsi ukuya kwinqanaba elithile, kwaye imveliso yawo yehlile. Okwangoku, izalathisi ze-petroleum coke e-sulfur ephantsi eShandong naseJiangsu zizinzile kwaye umxholo we-sulfur ngokusisiseko ugcinwa ngaphakathi kwe-0.5%, kwaye umgangatho uphuculwe kakhulu xa uthelekiswa nonyaka ophelileyo. Ukongeza, imfuno kwiindawo ezahlukeneyo ezisezantsi komlambo iya kwanda ngaphandle kokuphazamiseka kwixesha elizayo, ngoko ke ekuhambeni kwexesha, ukunqongophala kwezixhobo ze-petroleum coke zasekhaya ezi-sulfur ephantsi kuya kuba yinto eqhelekileyo.
