Workers in coal tar production units are exposed to polycyclic aromatic hydrocarbons (PAHs) and benzene. They have been followed since 1980. The first cytogenetic analyses revealed a mean frequency of 4.83% aberrant cells in the exposed group ( N =20) versus 1.50% aberrant cells in controls ( N =21).
Coal tar: a by-product in cokemaking and an essential raw. Jan 01, 2019 Coal tar production is not a primary process target: the main target in the process is the production of metallurgical coke for use in the blast furnace, with around 90% of the total world coke production being used for this purpose, while the remaining 10% is mainly used in cupola furnaces and for other industrial ...
26-12-2018· 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.
Coal Tar Pitch Market - Growth, Trends, COVID-19 Impact, and Forecasts (2021 - 2026) The market is segmented by Grade (Aluminum Grade, Binder and Impregnating Grade, and Special Grade), Application (Aluminum Smelting, Graphite Electrodes, Roofing, Carbon Fiber, Refractories, and Other Applications), and Geography (Asia-Pacific, North America, Europe, South America, and Middle-East and Africa)
09-02-2019· Coal tar is a by-product generated during the high temperature carbonizing of coking coal for the production of the metallurgical coke in the by-product coke ovens. It is a black, viscous, sometimes semi-solid, fluid of peculiar smell, which is condensed together with aqueous 'gas-liquor' (ammoniacal liquor), when the volatile products of the carbonization of coking coal are cooled down.

The tars obtained when coal is distilled in horizontal retorts for the production of either gas or coke are sufficiently similar to be classed under the head ing of coal tar. In the manufacture of gas, the coal is often mixed with bog head shale, bituminous lignite, etc., the gas being thereby en riched.
The production of tar pitches and binding agents for the manufacture of high-quality carbon materials is considered. The progressive scarcity of coal-tar pitch is noted.

Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railway tie preservative and used in the surfacing of roads.
