Njengomthombo ongavuseleleki, uwoyela unezimpawu ezahlukene zenkomba kuye ngokuthi uvelaphi. Kodwa-ke, uma sibheka izindawo zokugcina eziqinisekisiwe kanye nokusatshalaliswa kukawoyela ongahluziwe womhlaba wonke, izindawo zokugcina uwoyela ongahluziwe okhanyayo zingamathani ayizigidi eziyizinkulungwane ezingu-39, okungaphansi kwezindawo zokugcina uwoyela ongahluziwe onesibabule esikhulu, uwoyela ongahluziwe ophakathi nendawo kanye nowoyela ongahluziwe osindayo. Izindawo ezikhiqiza kakhulu emhlabeni yiNtshonalanga Afrika kuphela, iBrazil, iNorth Sea, iMedithera, iNyakatho Melika, iMpumalanga Ekude nakwezinye izindawo. Njengomkhiqizo ongaphansi kwenqubo yokucwenga yendabuko, ukukhiqizwa kwe-petroleum coke kanye nezinkomba kuhlobene kakhulu nezinkomba zikawoyela ongahluziwe. Kuthintwa yilokhu, ngokombono wesakhiwo se-petroleum coke yomhlaba wonke, isilinganiso se-petroleum coke esiphansi siphansi kakhulu kunese-petroleum coke esiphakathi nesiphezulu.
Ngokombono wokwabiwa kwesakhiwo sezinkomba ze-petroleum coke zaseShayina, umkhiqizo we-petroleum coke ene-sulfur ephansi (i-petroleum coke enokuqukethwe kwe-sulfur okungaphansi kuka-1.0%) u-14% womkhiqizo we-petroleum coke kazwelonke. Uqukethe cishe u-5% we-petroleum coke engenisiwe eShayina. Ake sibheke ukutholakala kwe-petroleum coke ene-sulfur ephansi eShayina eminyakeni emibili edlule.
Ngokusho kwedatha yeminyaka emibili edlule, umkhiqizo wanyanga zonke we-coke kaphethiloli e-low-sulfur ezindaweni zokuhluza zasekhaya uhlale cishe u-300,000 wamathani, kanti ukunikezwa kwe-coke kaphethiloli e-low-sulfur engenisiwe kuye kwashintshashintsha kakhulu, kwafinyelela esicongweni ngoNovemba 2021. Kodwa-ke, kunezimo lapho umthamo wanyanga zonke wokungeniswa kwe-coke kaphethiloli e-low-sulfur u-zero. Uma sibheka ukunikezwa kwe-coke kaphethiloli e-low-sulfur eShayina eminyakeni emibili edlule, ukunikezwa kwanyanga zonke kuye kwahlala ezingeni eliphezulu cishe lamathani angu-400,000 kusukela ngo-Agasti kulo nyaka.
Ngokombono wesidingo saseShayina se-coke kaphethiloli ene-sulfur ephansi, isetshenziswa kakhulu ekukhiqizweni kwama-electrode e-graphite, izinto zokwenziwa ze-graphite anode, ama-cathode e-graphite kanye nama-anode abhakiwe kusengaphambili. Isidingo se-coke kaphethiloli ene-sulfur ephansi emikhakheni emithathu yokuqala siyadingeka kakhulu, kanti isidingo se-coke kaphethiloli ene-sulfur ephansi emkhakheni wama-anode abhakiwe kusengaphambili sisetshenziswa kakhulu ekusetshenzisweni kwezinkomba, ikakhulukazi ukukhiqizwa kwama-anode abhakiwe kusengaphambili aphezulu anezidingo eziphezulu zokuqukethwe kwe-sulfur kanye nezinto zokulandelela. Kusukela ekuqaleni kwalo nyaka, ngokwanda komthombo we-coke kaphethiloli engenisiwe, izinsiza ezengeziwe ezinezakhi zokulandelela ezingcono sezifikile eHong Kong. Emkhakheni wama-anode abhakiwe kusengaphambili, ukukhetha izinto zokusetshenziswa kukhuphukile, futhi ukuncika kwawo ku-coke kaphethiloli ene-sulfur ephansi nakho kwehlile. Ngaphezu kwalokho, engxenyeni yesibili yalo nyaka, izinga lokusebenza lensimu ye-graphite electrode yasekhaya lehle laya ngaphansi kwama-30%, lehlela endaweni yokubanda yomlando. Ngakho-ke, kusukela kwikota yesine, ukunikezwa kwe-coke yasekhaya ye-low-sulfur petroleum kuye kwanda futhi isidingo sehlile, okuholele ekwehleni kwentengo ye-coke yasekhaya ye-low-sulfur petroleum.
Uma sibheka umkhuba wokushintsha kwentengo yefektri yokuhluza i-CNOOC eminyakeni emibili edlule, intengo ye-coke kaphethiloli ene-sulfur ephansi isiqalile ukuguquguquka isuka ezingeni eliphezulu kusukela engxenyeni yesibili yonyaka. Kodwa-ke, muva nje, imakethe ibonise kancane kancane izimpawu zokuzinza, ngoba isidingo se-coke kaphethiloli ene-sulfur ephansi emkhakheni wama-anode abhakiwe ngaphambilini sinesikhala esikhulu sokunwebeka. Umehluko wentengo phakathi kwe-coke kaphethiloli ene-sulfur ephansi kanye ne-coke kaphethiloli ene-sulfur ephansi ibuyile kancane kancane.
Ngokuphathelene nesidingo samanje emkhakheni ongezansi we-petroleum coke yasekhaya, ngaphezu kwesidingo esisheshayo sama-electrode e-graphite, isidingo sezinto zokwenziwa ze-graphite anode, ama-cathode e-graphite kanye nama-anode abhakiwe ngaphambilini sisaphezulu, kanti isidingo esiqinile se-petroleum coke yesulfure ephakathi nendawo nephansi sisaqinile. Sekukonke, esikhathini esifushane, izinsiza ze-coke ye-low-sulfur yasekhaya ziningi kakhulu, futhi ukwesekwa kwentengo kubuthakathaka, kodwa i-medium-sulfur petroleum coke isaqinile, edlala indima ethile yokusekela emakethe ye-low-sulfur petroleum coke.
