WebConverting Visbreakers to Delayed Cokers - 8 Delayed Coking Renewed interest in delayed coking: Attractive distillates yield C 5+ liquid yield 55-65wt% Eliminates fuel oil … WebCoking is the primary process used to upgrade petroleum residues. This process produces a solid coke which has a high carbon content. There are two types of coking processes, fluid cokers and delayed cokers. The delayed coking process is much more prevalent. In delayed coking, the process is designed so that the coke forms in a drum.
Webcoker gas composition is given in Table below. Fluid Coking Fluid coking is a thermal cracking process consisting of a fluidized bed reactor and a fluidized bed burner as shown in Figure below. Vacuum residue is heated to 260 °C (500 F) and is fed into the scrubber which is located above the reactor for coke fine particle recovery, WebThere are two classes of coking technology employed industrially, namely, delayed coking and fluid coking [22,23]. Delayed coking is the most widely used. The process configuration of a delayed coking unit resembles that of visbreaking ( Figure 5.4 ), but the operation is more severe – slightly higher temperature and much longer residence time.
WebIn the delayed coker the feed enters the bottom of the fractionator where it mixes with recycle liquid condensed from the coke drum effluent. It is pumped through the coking heater then to one of two coke drums … WebAug 9, 2016 · Two types of coking processes exist — delayed coking and fluid coking.
