What is coking and decoking?
petroleum refining In petroleum refining: Visbreaking, thermal cracking, and coking. Decoking is a routine daily occurrence accomplished by a high-pressure water jet. First the top and bottom heads of the coke drum are removed. Next a hole is drilled in the coke from the top to the bottom of the vessel.
How does a coker work?
In a refinery, the coker is the most extreme of the bottoms upgrading process units. A coker takes the lowest value bottoms material (vacuum resid) and cracks it to the point that all of the resid is eliminated, yielding only lighter fractions and solid carbon (pet coke).
What Decoking means?
Verb. 1. decoke – remove carbon from (an engine) decarbonise, decarbonize, decarburise, decarburize.
Is Coker a German name?
English: habitational name from a group of villages in Somerset named with Coker, from a Celtic river name meaning ‘crooked’.
How does a Coker work in an oil refinery?
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. The process thermally cracks the long chain hydrocarbon molecules in the residual oil feed…
What is the purpose of a coker unit?
A coker unit is a thermal cracking process in the oil refinery industry used to recover valuable elements, the most important of which being petroleum coke from main refinery process residues.
What kind of oil is in a coker unit?
Coker unit. 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.
What does coking mean in the petroleum industry?
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. Exports of petroleum coke accounted for about 19% of the nation’s finished petroleum product exports through October 2012
