Delayed coker Wikipedia

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

Coking an overview | ScienceDirect Topics

DELAYED COKING PROCESS. Description: Delayed coking process is a thermal process which increases the molecular aggregation or association in petroleum-based residues or coal tar pitches leading to extended mesophase domains. This is achieved by holding them at an elevated temperature (usually 750 K–765 K) over a period of time (12 to 36 h).
