Petroleum Coke yog tsim los ntawm cov txheej txheem roj av refining. Thawj theem yog rho tawm cov khoom siv raw (cov roj crude) hauv av tom qab drilling ib lub qhov dej. Qhov thib ob theem yog thauj cov ntaub ntawv no mus rau cov roj refinery.
Cov roj refineries ua kom cov roj ntsha nyoos no rau hauv cov khoom siv tau rau kev ua lag luam-piv txwv li, roj av, roj av, roj av, roj av, roj av, thiab lwm yam derivatives.
Refining petroleum hydrocarbons suav nrog cov khoom siv, theem, txheej txheem, thiab tshuaj lom neeg cov tshuaj tiv thaiv kom tau txais cov khoom kawg.
Nyob rau theem no, cov ntaub ntawv raw yog rhuab mus rau qhov kub siab heev nyob rau hauv distillation yees thiab nias rau high pressures. Tom qab ntawd, txhua qhov sib xyaw hydrocarbon sib cais ntawm qee qhov siab thiab kub.
Cov seem ntawm cov derivatives no tseem nyob hauv daim ntawv ntawm cov kua roj av. Ntawm no, cov kua dej no raug xa mus rau cov chav tshwj xeeb hu ua "coking units" kom tiav cov txheej txheem lim. Tom qab ntawd, cov kua dej no tau ua tiav ntawm qhov kub thiab txias los tsim Petroleum coke hauv daim ntawv ntawm cov khib nyiab tom qab tshem tawm tag nrho cov roj thiab cov khoom tsis haum. Thaum kawg, tag nrho cov roj teeb uas tseem tshuav thiab hnyav tau sib cais.
Qhov tshwm sim roj av coke nyob rau theem no yog hu ua Green Petroleum Coke (CVP). Hauv luv luv, tseem yuav tsum tau ua tiav. Petroleum Coke tuaj yeem siv tau ntawm no hauv qee daim ntawv thov, tab sis lwm tus yuav tsum tau ua ntau dua thiab hu ua "Calcined Coke". Cov txheej txheem no txhais tau tias hloov cov roj av coke mus rau lub tshuab hluav taws xob kom tshem tawm cov seem uas tsis muaj hluav taws xob hydrocarbon residues.
Cov calcined roj av coke tuaj yeem ua tiav hauv qhov cub anode ci. Nws tsim coke, uas yog siv feem ntau hauv kev tsim steel lossis aluminium.
Rau kev khaws cia thiab kev thauj mus los, xws li thee, roj av coke yog khaws cia rau hauv pawg loj hauv hnab lossis silos. Conveyors, hopper siv, thiab trolleys tau yooj yim thauj nws.
Vim cov roj av coke yog cov nplua nuj carbon, nws yuav tsum tau muab cia rau hauv qhov chaw qhuav.
Nws yuav tsim ib qho nyuaj hu ua "damp coke" yog tias ntub. Nws yog ib yam khoom uas nyuaj rau tshem tawm. Feem ntau nws tuaj yeem tawg yooj yim los yog tshem tawm los ntawm kev siv lub ripper, uas yog lub zog siab dej hose.
