Coal tar, a black, sticky liquid thicker than water, is produced when coal is heated in the absence of air, a process called destructive distillation. Much coal tar is produced by the steel industry as it produces millions of tons of coke each year to fuel the furnaces used in separating iron from its ores.
Coal tar is obtained by cooling the gas that is formed during the destructive distillation of coal to approximately ambient temperature. It is a black, viscous liquid composed prima rily of a complex mixture of condensedring aromatic hydrocarbons.
The plasma torch operates with different plasma working gases, including steam. The results of coal tar pitch (CTP) processing will be presented as a possible ecological application. ... (CTP), a byproduct of the coal tar distillation process, is an abundant source for the production of syngas and carbon nanomaterial due to its polycyclic ...
Coal tar is a complex hydrocarbon mixture produced by thermal destruction (pyrolysis) of coal, typically a dark viscous liquid or semisolid with a smoky or naphthenic odor. The composition of coal tar will be influenced by the process used for pyrolytic distillation as well as by the original composition of the coal; however, all coal tars will ...
The coal tar distillation process normally requires high during the distillation process, a study of energy analysis in the coal tar distillation process needs to be done. This study aims to analyze the energy consumption of the distillation process by using simulator software. Process simulations will be performed using the Aspen HYSYS simulator,
1. Introduction Coal gasification technology has become an important technology to produce alternative fuels to replace gas and oil fuels. But on the other hand, coal gasification byproducts, including coal tar, sulfur, ammonium sulfate and crude benzol, become a problem to the environment.
Destructive distillation of coal is a process in which coal is heated strongly in the absence of air. coal contains number of different elements, such as. Hydrogen. Oxygen. Nitrogen. Sulphur. When coal is subjected in destructive distillation then it produce number of product such as, coal tar and coal gas. Actually, coal tar and coal gas is ...
1. Exposure Data Manufacturing process Coal tar is obtained by cooling the gas that is formed during the destructive distillation of coal to approximately ambient temperature. It is a black, viscous liquid composed primarily of a complex mixture of condensedring aromatic hydrocarbons.
Coaltar pitch is the residue from the distillation of coal tar. It is a black soHd having a softening point of 30—180°C (86—359°F). [] The principal binder material, coaltar pitch, is produced by the distillation of coal tar. Coal tar is obtained primarily as a byproduct of the destmctive distillation of bituminous coal in coke ...
If there is a high amount, it will have a naphthalike smell, otherwise it will smell more of tar. In the process of coaltar distillation, the distillate is collected into four fractions; the "light oil", which remains lighter than water, the "middle oil" which passes over when the light oil is removed; the "heavy oil", which sinks; and the ...
Coal Tar and its Distillation Processes Coal tar, also known as crude tar, is the byproduct generated during the high temperature carbonizing of coking coal for the production of the metallurgical coke in the byproduct coke ovens.
Coaltar pitch (CTP) is a solid residue derived from coal tar distillation process, and its yield is generally in the range of 5060 wt% of coal tar. Coal tar yield usually accounts for ∼35 wt% of coal (dry basis) for producing coke. coke yield is usually in the range of ∼7580 wt% of dry basis coal (Granda et al., 2014). Therefore ...
Coal Tar. Richard D. Phillips, in Encyclopedia of Toxicology (Second Edition), 2005 Uses. Coal tar is a viscous liquid mixture of hydrocarbon compounds, derived along with coke, from the destructive distillation of coal in coking ovens. Coal tar itself may be subjected to distillation, a process that separates groups of the components of coal tar from groups of others.

The invention discloses a method for extracting industrial naphthalene from coal tar, and belongs to the field of coal chemical industry. According to the method, coal tar is taken as a raw material; naphthalene is fractionated through a weightremoving column; firstly crude naphthalene is obtained; and then industrial naphthalene is prepared through a crude naphthalene rectifying column.

COAL TAR DISTILLATION (EIRI1092) Coaltar is produced by the dry distillation of coal and is therefore a by product in the manufacture. of coal gas. For a considerable time after the discovery of coal gas, the tar produced was considered. merely an encumbrance and was used mainly as a pigment or fuel. The purification of coaltar is.
