In petroleum refining, a relatively severe thermal cracking process designed to completely convert residual oils into gases, naphtha, gas-oil and coke. The gas-oil fraction is usually the major product obtained from coking, and is used primarily as catalytic cracker feedstock. The coke obtained from the process is usually consumed as fuel, although there are a number of specialized products made from coke, such as electrode raw material, chemicals and metallurgical coke. These latter products require further processing of the basic petroleum coke obtained from this process. There are several different coking processes employed commercially, including delayed coking, fluid coking and Fexicoking.
A refining process for thermally converting and upgrading heavy residual into lighter products and petroleum coke.
A thermal cracking process to break up large molecules into smaller ones with the generation of quantities of petroleum coke.
Black carbon particles that can be the result of severe overheating of the fluid. See also Colloidal Carbon.
The process by which a product that is being heated is broken down in the absence of oxygen. Also called charring.
a refining process by which the denser, heavier products of the distillation process (residuals) are converted to lighter products such as cat feed and naphtha, and petroleum coke, a solid, coal-like fuel. The coking unit, or "coker," heats hydrocarbons to near 800 degrees Fahrenheit, at which temperature all the lighter products vaporize, and the coke solidifies in a large drum (called a "coke drum"), from which it is removed by means of high-pressure jets of water.
Process of heating coal in a coke oven in the absence of air to high temperatures between 1000 C and 1100 C for 16 to 20 hours to produce a very pure form of carbon
Processes for thermally converting and upgrading heavy residual oil into lighter products and by-product petroleum coke.
Extraction of gases from coal. The resulting material is called coke.
Thermal refining processes used to produce fuel gas, gasoline blendstocks, distillates, and petroleum coke from the heavier products of atomspheric and vacuum distillation.
Removing carbon from bitumen to produce lighter hydrocarbons
In a pump, where a reduction of hydrocarbons results in the formation of carbon residue that will interfere with the movement of a mechanical seal. Also referred to as Carbonizing.
