Superheated Furnace Effluent flows directly into an empty Coke Drum (one of a matched pair of Drums) where a combination of lengthy residence time (typically in the 18-hour range) and high temperature sustain the Cracking Reactions which build up a bed of Solid Coke and Cracked Hydrocarbon Vapor Products.

While the Coke Drum is filling, its parallel (sister) Drum is undergoing Steam Stripping, Cooling, Water Draining, Top and Bottom Head Removal, High Pressure Water Jet Coke Cutting, re-Heading, Air-Freeing and pre-Heating in preparation for return to service as the receptacle for the continuous flow of the superheated Furnace Effluent Stream. These cycles are repeated until the entire Coker Plant must be shut down for required maintenance, inspection and equipment cleaning.
