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, WebTraditionally, to minimize the quantity of coke formed, the pressure in the coke drum is set at minimum levels. In today's delayed cokers, the minimum practical pressure level is 6.89 x 10⁴ to 1.03 x 10⁵ Nm⁻² (10 to 15 psig). To achieve lower pressures requires large and expensive equipment with high compression requirements.
WebThe delayed coker model provides a fundamental kinetic representation of the delayed coker operation, and the input page is shown in Figure 2. The following discussion used a simplified version of the simulation model thermal cracking kinetics to explore the reaction yield effect for a single feedstock, to allow comparison to the hydrocracker ... 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.
WebAug 9, 2016 · Two types of coking processes exist — delayed coking and fluid coking. Both are physical processes that occur at pressures slightly higher than atmospheric and … WebCoking takes place in one drum in 24 hours while decoking is carried out in the other drum. A complete cycle is 48 hours. Coke is cut from the drum using high pressure water. …

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.
