A coker or coker unit is an oil refinery processing unit that converts the residual oil from the vacuum distillation column into low molecular weight hydrocarbon gases, naphtha, light and heavy gas oils, and petroleum coke.

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 .

2013年1月28日 · Coking is a refinery unit operation that upgrades material called bottoms from the atmospheric or vacuum distillation column into higher-value products and, as the name implies, produces petroleum coke—a coal-like material.

Delayed Coker (Coker) feedstock is material from the refinery vacuum unit, which is otherwise used as road asphalt. The objective of the Coker is to process the asphalt-like material to produce higher value products, such as gasoline, diesel fuel, …

2020年12月29日 · Coking process is nothing but a refinery unit operation to upgrade vacuum residue from bottom of vacuum distillation column into more valuable products using thermal cracking. The objective of the process is to increase the yield of distillate products. Vacuum residue is also called as bottom of the barrel. Article Written By : C Saravanakumar

A delayed coker is a type of coker whose process consists of heating the residual oil feed to its thermal cracking temperature in a multi parallel pass furnace. This cracks the long chain heavy carbon and hydrogen molecules of the residual oil into coker gas oil and pet coke.

Delayed Coking is a refinery unit operation that upgrades the lowest value bottoms material (vacuum resid) from the atmospheric or vacuum distillation column and cracks it to the point that all of the resid is eliminated. This process yields lighter fractions and solid carbon into higher-value products and produces petroleum coke—a coal-like ...

Delayed Coking is an endothermic process with the Coker Heater supplying the necessary heat of reaction. The exact mechanism of coking is so complex that it is not possible to determine all the chemical reactions occurring. Three distinct steps do take place:

A coker or coker unit is an oil refinery processing unit that converts the residual oil from the vacuum distillation column or the atmospheric distillation column into low molecular weight hydrocarbon gases, naphtha, light and heavy gas oils, and petroleum coke.

The Delayed Coker Unit uses dual coke drums to which process feed is alternated, while one drum is being filled the second drum is being cooled followed by hydraulic coke cutting & water separation for reuse. In delayed coking, the feed is typically the residue from vacuum distillation tower and frequently includes other heavy oils.
