I ʻOkakopa, ua piʻi aʻe ka mākeke petroleum coke me ka haʻalulu, ʻoiai ua haʻahaʻa ka hana o ka petroleum coke. Ua piʻi aʻe ke kumukūʻai o ke kalapona alumini, a ua mālama ke koi no ke kalapona alumini, ke kalapona kila, a me ka poloka kalapona cathode i ke kākoʻo no ka petroleum coke. Ua piʻi aʻe ke kumukūʻai holoʻokoʻa o ka petroleum coke, a ua hoʻopilikia ʻia kekahi mau ʻano e ka palena o ka nūhou vanadium ma lalo, e hoʻoulu ai i nā loli kumukūʻai pōkole. Ua piʻi ke kumukūʻai o ka coke Sinopec he 30-110 yuan/ton, ua piʻi ke kumukūʻai o ka coke PETROCHINA he 50-800 yuan/ton, ua piʻi ka ʻāpana CNOOC he 100-200 yuan/ton, a ua piʻi ke kumukūʻai coking kūloko he 50-220 yuan/ton.
ʻO ka nānā ʻana i nā kumu nui e hoʻohuli ai i ka mākeke coke petroleum i ʻOkakopa: 1. Haʻahaʻa ka hana coke petroleum a Sinopec, a loli ka hana coke petroleum o nā hale hoʻomaʻemaʻe kūloko kekahi i kekahi. Manaʻo ʻia e piʻi iki ka hana coke petroleum a Petrochina, ʻoiai ʻo ka hana a Cnooc ke kūpaʻa nei, a manaʻo ʻia e kaupalena ʻia ka ulu ʻana o ka hana holoʻokoʻa, a ke hoʻomau nei ka hana coke petroleum kūloko haʻahaʻa i ke kākoʻo ʻana i ke kumukūʻai mākeke piʻi. ʻO ka lua, ua mālama ke koi o ka alumini electrolytic downstream, carbon a me ka electrode maikaʻi ʻole i ke kākoʻo paʻa, a ua haʻahaʻa ka hana o ka coke low-sulfur ma kekahi mau hale hoʻomaʻemaʻe me ka piʻi nui. I ʻOkakopa, ua loaʻa i ka nūhou o The Limit of vanadium ma Weiqiao, Shandong kahi hopena i ka mākeke coke petroleum a puni i ka wā pōkole. Ua loli ke kūʻai aku a me nā kumukūʻai o kekahi coke petroleum vanadium kiʻekiʻe i ka wā pōkole i waenakonu o ka mahina. Ma muli o ka waihona haʻahaʻa holoʻokoʻa ma downstream, ua ikaika ke koi no ka coke petroleum. ʻO ke kolu, ke hoʻomau nei ke kumukūʻai o ka coke sponge o waho, ʻoi aku ke kiʻekiʻe o ke kumukūʻai wahi awa.
No ka ʻike hou aku e pili ana i kā mākou huahana e ʻoluʻolu e hoʻokaʻaʻike mai
