WebAug 20, 2001 · The feed-maximization control strategy for the coker uses a coke-yield program package integrated with a commercial MPC (Fig. 2). The coke-yield program continuously estimates the current coke... A coker or coker unit is an oil refinery processing unit that converts the residual oil from the vacuum distillation column into low molecular weight hydrocarbon gases, naphtha, light and heavy gas oils, and petroleum coke. The process thermally cracks the long chain hydrocarbon molecules in the residual oil feed into shorter chain molecules leaving behind the excess carbon in the form of petroleum coke.

WebCoking processes are processes in which the feedstock is thermally decomposed into lower boiling products. The major subforms of the coking process are (1) the delayed coking process and (2) the fluid coking process. WebWood’s selective-yield delayed coking technology (SYDEC SM) is the leading method for residue upgrading for zero-fuel oil production. It provides refiners with the flexibility to utilise a variety of residues in their cokers to reduce waste and support energy transition objectives.

WebCommercial delayed coker feedstocks and corresponding green cokes were obtained from four refineries. The feedstock materials were characterized by infrared, chromatographic, and solvent extraction techniques in addition to the conventional physical tests and chemical analyses. The green cokes were calcined in a laboratory induction furnace at ...
