WikiZero - Delayed coker

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.. Delayed coking is one of the unit processes used in many oil refineries.The adjacent photograph depicts a
