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 …

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.

A coking factory or a coking plant is where coke and manufactured gas are synthesized from coal using a dry distillation process. The volatile components of the pyrolyzed coal, released by heating to a temperature of between 900 °C and 1,400 °C, are generally drawn off and recovered.

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.

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, …

An ironmaking plant consists of blast furnace, coking plant, sintering, and/or pelletizing plant. Both coking plant and blast furnace generate significant amount of extra heat in the form of COG and blast furnace-top gas.

Steam is added to prevent coking in the heater, and the heated feed is introduced from the bottom of one of the coke drums. The coking takes place in the insulated coke drum as the drum fills up for a period of 16–18 h.

In delayed coking, the feed is typically the residue from vacuum distillation tower and frequently includes other heavy oils. The feed is heated by a fired heater (furnace) as it is pumped in from the bottom and solidifies as it cools.

A coking plant is used to produce coke (coking coal) from metallurgical coal. Coking plants consist of coke ovens (aka coking ovens, coke furnaces, coking furnaces). Coal is used to reduced iron ore to produce pig iron (aka hot metal) in the blast furnace (BF). However, it cannot be burned directly in the furnace because it contains numerous ...
