Webproperties [12]. Flexi coking differs from fluid coking only because of the presence of gasification unit in flexi-coking. In flexi coking there is complete or partial gasification of the petroleum coke to yield a fuel gas. It is different from the bulk liquid-phase coking in delayed coking. In flexi coking WebThe delayed coking process involves heating hydrocarbon liquids in a coking furnace and transferring the heated liquids to a coking drum where the liquids decompose into coke and volatile components. In order to practically use the delayed coking process, a coker fractionation system is needed along with the coking furnace and coking drums.

WebTypes of Coker Units. There are two primary types of coker units used in petroleum refining: delayed coker units (DCU) and fluid coker units. Of the two, the delayed coker unit (DCU) is by far the most common and involves two or more drums working in tandem. When one drum is taken offline, production is simply shifted to the next drum. WebThe delayed coker model provides a fundamental kinetic representation of the delayed coker operation, and the input page is shown in Figure 2.
