What is coal tar?

Iran Coal tar is a thick black liquid produced by processing bituminous coal, containing various types of hydrocarbon ethyl benzene, Chloronaphthalene, hydroxyl group, phenyl group, and many other chemical elements. Coal tar is a brown or black liquid of extremely high viscosity. Coal tar is among the by-products when coal is carbonized to make coke or gasified to make coal gas.

What is a difference of coal tar and Bitumen?

Coal tar is created from planet and threes but bitumen created from dissolution of animals.

Application of Iran coal tar

A purpose of the invention is to distill high temperature coal tar (tar produced in coke ovens, gas retorts and the like at a nal coking temperature in excess of 750 C.) containing from 5 to 15 percent by volume and usually from 8 to l2 percent by volume of naphthalene, called tar herein, in two stages, to dehydrate the tar and remove light coal-tar solvent oil under vacuum in a lirst stage, to introduce the solvent oil from the rst stage into a second stage, and to distill under vacuum in the second stage the residue from the first stage plus the added solvent oil.

How process coal tar

Crude Coal Tar is a byproduct of the Coking process. Coking is the process of heating coal in coke ovens to drive volatile matter from it. Metallurgical Coke is used as a fuel and reducing agent in the production of iron, steel, ferro-alloys, elemental phosphorus, calcium carbide and numerous other processes.

Gilsonite powder is oil well drilling mud additiveFor many years, Gilsonite has been added to drilling fluids to stabilise boreholes through shale stratigraphic intervals, preventing borehole enlargement. It is plugs micro fractures, bedding plane voids, and pore spaces and forms a thin film on the borehole wall. Gilsonite is added at about 1 to 3 kg per barrel of drilling mud. It is also reduces drill string torque and drag, and thus reduces the likelihood of stuck drill strings [...]

Natural asphalt is derived from the natural mutation of petroleum. This mutation happened a million years again under the influence of bacteria. This bacterial decomposition of petroleum resulted in reduce content of saturated hydrocarbons, mainly n-alkalenes and light oil which became heavier and more viscous , taking the form of asphalt. It is natural product a bituminous limestone in which carbonate of lime and pure natural asphalt are most intimately combined by natural agency. It is as bitumen created in the [...]
