Coking FSC 432: Petroleum Refining John A Dutton e
Three different coking processes are used in the refineries: delayed coking, fluid coking, and flexicoking (a variation of fluid coking) The common objective of the three coking processes is to maximize the yield of distillate products in a refinery by rejecting large quantities of carbon in the residue as solid coke, known as petroleum cokeAll of the heat necessary for coking is provided in the heater, whereas coking takes place in the coke drum; hence, the process is called “delayed coking”Delayed Coking FSC 432: Petroleum Refining John A2014年1月1日 Abstract — Petroleum coke is a process that involves steps such as thermal decomposition, polymerizationion and condensation Flow scheme of general electrode p roduction shown in figure 3(PDF) Calcinations of Petroleum coke ResearchGatecontributors Process flow schemes, emission characteristics, and emission control technology are discussed for each process Tables 511 and 512 list the emission s factors for direct process emissions in petroleum refineries Factors are expressed in units of kilograms per 1000 liters (kg/103 L) or51 Petroleum Refining1 US Environmental Protection Agency
