Coking is the process of changing residual oil to low molecular weight gases, naphtha, and gas oils. Coking is a severe method of thermal cracking used to upgrade heavy residuals into lighter products or distillates.
What is the coking process?
Coking is a refinery process that produces 19% of finished petroleum product exports. … 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.
What does a coking plant do?
Both coking plant and blast furnace generate significant amount of extra heat in the form of COG and blast furnace-top gas. Both gases are secondary fuels, and are utilized in most cases internally (within ironmaking and steelmaking plants) for providing energy sources in other unit operations.
What do you mean by coking coal?
Coking coal, also known as metallurgical coal, is used to create coke, one of the key irreplaceable inputs for the production of steel. There are many varieties of coal in the world, ranging from brown coal or lignite to anthracite. … Coke is produced by heating coking coals in a coke oven in a reducing atmosphere.
What does weart mean?
exhausted in strength, endurance
Why it is called delayed coking?
Steam is added to prevent coking in the heater and the heated feed is introduced from the bottom of one of the coke drums. … All of the heat necessary for coking is provided in the heater, whereas coking takes place in the coke drum; hence, the process is called “delayed coking.”

What is Coke vs coal?
By distilling bituminous coal in retorts to obtain gas for illumination, or by burning it in kilns or pits, the residue left behind is called coke, which is simply coal charcoal, and is nearly pure carbon.
Is Coke a fossil fuel?
Coal gas, coke and producer gas are the byproducts of coal and are not fossil fuels, except natural gas which is a fossil fuel.
What are 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
What is the name for the highest rank coal?
Anthracite. Anthracite is the highest rank coal. It is a black, shiny, hard rock and is not friable. It is low in volatile matter and this makes it difficult to burn in rotary kilns.
What’s the difference between thermal and coking coal?
Thermal coal, also called steaming coal, has a lower energy content and higher moisture and is used to generate electricity. Metallurgical or coking coal has a higher energy content and lower moisture and is used to make iron, steel and other metals.
