Mea hoʻoulu hou: CPC Calcined Petroleum Coke no ka hao i hoʻolei ʻia

Wehewehe Pōkole:

He mea nui ka Calcined Petroleum Coke i ka hana ʻana o ka alumini. Hana ʻia ia ma ke kau ʻana i ka "ʻōmaʻomaʻo" petroleum coke maka kiʻekiʻe i loko o nā umu wili, kahi e hoʻomehana ʻia ai i nā mahana ma waena o 1200 a 1350 degere C (2192 a 2460 F). Hoʻopau nā mahana kiʻekiʻe i ka makū keu, unuhi i nā hydrocarbons i koe a hoʻololi i ke ʻano crystalline o ka coke, e hopena ana i kahi huahana denser ʻoi aku ka uila. I loko o kekahi mau hola, hoʻomaʻalili ʻia ka calcined petroleum coke mai 1350 degere C a i lalo o 200 degere C, i ka wā e hiki ai ke lawelawe palekana a lawe ʻia i nā silos mālama a waiho pololei ʻia i loko o nā ipu hoʻouna, nā kalaka, nā kaʻa kaʻaahi, nā barges a i ʻole nā ​​​​moku.

He ʻano ʻūpā ko ka coke petroleum i hoʻokahe ʻia e like me ka huʻahuʻa e pāʻani ana i kahi hana koʻikoʻi i ka hana ʻana i nā anodes. ʻAe nā pores i nā mea hoʻopaʻa e komo i loko o nā ʻāpana coke a hana i kahi poloka kalapona paʻa, kahi e alakaʻi ai nā mea hoʻoheheʻe alumini i ka uila i loko o kā lākou mau ipu hoʻoheheʻe. I ka hala ʻana o ka manawa, hoʻopau ʻia nā anodes, ma kahi o 40 tons o ka coke petroleum i hoʻokahe ʻia no kēlā me kēia 100 tons o ka alumini i hana ʻia. I kēia manawa, ʻaʻohe mea i ʻike ʻia he pani kūpono no ka coke petroleum i hoʻokahe ʻia i ka hana ʻana a me ka hoʻohana ʻana i nā anodes smelter alumini.
