We are exporter of Iran coal tar in different form of soft,medium and extra hard
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.
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.
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.
