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. 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. trump interview with barbara walters
