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.

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.

The process C is Destructive distillation. Destructive distillation is a chemical process of decomposition of a solid by heating it in a closed container. The volatile constituents produced in this process can be separated. Coal is processed in industry to get some useful products such as coke, coal tar and coal gas.

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 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 ...
