WebAs a result of extreme temperatures required by the delayed coking process, an incident in the coker often causes damage to surrounding equipment. Among the types of equipment affected are instrumentation, piping, valves, pumps, electrical wiring, insulation, hydraulic and air tubing, and others. A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke.
