A crude oil refinery is a group of industrial facilities that turns crude oil and other inputs into finished petroleum products. A refinery's capacity refers to the maximum amount of crude oil designed to flow into the distillation unit of a refinery, also known as the crude unit.

Crude coal tar By crude coal tar as used herein is meant the crude coal tar product obtained as a by-product in the distillation of coal (anthracite or bituminous) to produce combustible gas, which distillation may be carried out either at relatively high temperatures, for example, in by-product coke ovens or retorts, or at lower temperatures ...
During the distillation of crude coal tar, light and medium weight oils are removed from the crude coal tar to produce various refined coal tar products such as RT-12. These light and medium oils represent 20-50% by weight of the crude coal tar depending up the refined product that you are making.

Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal …
Crude Coal Tar - Information; Why it is Recommended. COAL TAR, the viscous, oily fraction of the liquid distillates obtained in the manufacture of coal-gas or of coke by the destruc tive distillation (see CARBONIZATION) of bituminous coal at 90o I200° C.
Tar→ From Destructive Distillation (Burning in Specific Condition of Temperature, Without Presence of Oxygen) of Bituminous Coal; Bitumen→ Obtained From Refining Process (Fractional Distillation) of Crude Oil (A Petroleum Product) * For Manufacturing of Tar, Coal is Burnt Without Presence of Oxygen.
COAL TAR, the viscous, oily fraction of the liquid distillates obtained in the manufacture of coal-gas or of coke by the destruc tive distillation (see CARBONIZATION) of bituminous coal at 90o I200° C.
Coal tar is a material obtained from the destructive distillation of coal in the production of coal gas. The crude tar contains a large number of organic compounds (e.g. benzene, naphthalene, methylbenzene, etc.), which can be separated by fractional distillation.
Benzene is a natural component of crude oil, and is one of the most elementary petrochemicals. In 1845, Hoffmann isolated benzene from coal-tar . Benzene molecular formula is C 6 H 6 and benzene structure is having alternative double bonds with hexagon shape.
Coal Tar and its Distillation Processes. Coal tar, also known as crude tar, is the by-product generated during the high temperature carbonizing of coking coal for the production of the metallurgical coke in the by-product coke ovens.
Distillation of Coal-Tar. - Much more important than all applications of crude coal-tar is the industry of separating its constituents from it in a more or less pure form by fractional distillation, mostly followed by purifying processes.

Vacuum distillation is a part of the refining process that helps to produce petroleum products out of the heavier oils left over from atmospheric distillation. In the refining process, the atmospheric distillation unit (ADU) separates the lighter hydrocarbons from the heavier oils based on boiling point. The ADU is capable of boiling crude oil ...
For vacuum distillation of crude coal tar, the crude coal tar is produced from coke ovens of steel plant, 50% of this crude coal tar is pitch. The crude coal tar is then taken to vacuum distillation columns for fractionating into various components. Coal tar is produced by the dry distillation of coal and is therefore a by product in the ...
