What is coke in the refining process?
Petroleum coke, or petcoke, is a product produced from all types of oil (light/heavy crudes) during the oil refining process. Many different products are extracted from a barrel of crude oil in addition to gasoline, diesel and jet fuels. Petroleum coke just one of the many.
What are coking operations?
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 is Mopag price?

What is Platts price?
Platts means a price benchmark service for the oil industry. Platts pricing plus a premium or minus a discount is the preferred pricing mechanism on this requirement.
What is coke formation?
The gaseous coke is formed by the dehydrogenation of light olefinic hydrocarbon such as acetylene and the condensation coke is formed by condensation /polymerization /dehydrogenation of heavy aromatic compounds. The decoking of pyrolytic coke can be easier than that of catalytic coke.
How is coke obtained?
Coke is produced by heating coal at high temperatures, for long periods of time. This heating is called “thermal distillation” or “pyrolysis.” In order to produce coke that will be used in blast furnaces, coal is usually thermally distilled for 15 to 18 hours, but the process can take up to 36 hours.
Why is it called coking?
The industrial production of coke from coal is called coking. The coal is baked in an airless kiln, a “coke furnace” or “coking oven”, at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F).
What are coking properties?
Generally coking properties of coal deteriorates on storage and unless adequate precautions are taken to prevent oxidation, the coke generated by HTC process are found to be inferior grade. From: Coal Science and Engineering, 2012.

What is the role of coke in metallurgical process?
Metallurgical coke, along with iron ore and limestone, is layered into a blast furnace to convert the iron ore to metallic iron. Coke, which is mostly carbon, reacts with the blast air to produce carbon monoxide, which, in turn, reacts with the iron oxide to produce carbon dioxide and metallic iron.
What is difference between coal and coke?
Coal and Coke are both a type of fossil fuels. The difference between these two fuels is that coal is mostly carbon but coke contains mostly water and less than half the carbon content of coal.
What are two uses for coke?
The most common use of coke is as a fuel for stoves, furnaces and blacksmithing….Uses of coke
- It is also used to produce iron in a blast furnace.
- Coke is used to manufacture steel and many other materials.
- Used as a reducing agent in the extraction of metals. Example- Zinc and Iron, etc.
What is the difference between coking and non coking coal?
Noncoking coals have higher ash content and are typically used in thermal power plants as steam coals. Coking coal is the type of coal which on heating in the absence of air undergoes a transformation into a plastic state, swells, and then solidifies to form coke.
What is difference between coking and non coking coal?
