Coaltar pitch is a thick black liquid that remains after the distillation of coal tar. It is used as a base for coatings and paint, in roofing and paving, and as a binder in asphalt products. Both coal tar and coaltar pitch contain many chemical compounds, including carcinogens such as benzene.
Product Stewardship Summary Coal Tar Pitch (CAS number ) (EC number ) Product Description Coal tar pitch is a black, viscous residue that remains after the distillation of coal tar. This process occurs at our plants and involves heating coal tar (the raw material used to produce coal tar pitch) in a still. As the

For a more detailed description of the coaltar distillation process, see the previous IARC Monograph (IARC, 2010). Occupational exposure Concentrations of PAHs in the ambient air and in urine of workers in coaltar distillation have been measured in several studies. The results are summarized in Table . The levels of
It is of this third class of products of the destructive distillation of bituminous coal, much more complex and, perhaps, for that reason much less known than the other two classes, that we wish particularly to speak this evening. This mixture is known collec tively under the name of " coaltar."
For a more detailed description of the coaltar distillation process, including coaltar pitch, the reader is referred to IARC Monograph Volume 92 (IARC, 2010), and to the Monograph on Occupational Exposures during Coaltar Distillation in this volume.

Coal tars and coaltar pitches have many uses in industry and in consumer products. Coal tars are used primarily for the production of refined chemicals and coaltar products, such as creosote, coaltar pitch, and crude naphthalene and anthracene oils from the distillation of crude coal tar. Coal tar has been used as a fuel in openhearth fur
Coal tar is among the byproducts when coal is carbonized to make coke or gasified to make coal gas. Coal tars are complex and variable mixtures of phenols, polycyclic aromatic hydro carbons, and metro cyclic compounds, about 200 substances in all. Coal tar .

Coal tar distillates are derived from the distillation of coal tars at coal tar refinery facilities. They are made of complex combinations of compounds, mainly aromatic hydrocarbons. Their composition varies based on their source, the heating temperature, and the distillation temperature for the distillates.
Coal tar is produced through thermal destruction of coal. Its composition varies with the process and type of coal used – lignite, bituminous or anthracite. Coal tar contains approximately 10,000 chemicals, of which only about 50% have been identified.
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 manufacture of coal gas. Coal tar pitch serves as a valuable ingredient in the production of a number of water proofing, protective and binding ...
Feb 26, 2019· Segment: of China''s coal tar products, over 70% are hightemperature coal tar, a byproduct from coke production. Hightemperature coal tar .
Destructive distillation of a tonne of coal can produce 700 kg of coke, 100 liters of liquor ammonia, 50 liters of coal tar and 400 m 3 of coal gas. Destructive distillation is an increasingly promising method for recycling monomers derived from waste polymers.
A typical tar distillation plant is the Woodall–Duckham still (see DISTILLATION). The tar, separated from excess of aqueous liquor by long settling, is charged into the still and heat applied either by means of coal or (as in cokeoven installations) of surplus gas, which permits of very delicate heat control.
Dec 26, 2018· The primary objective of coal tar distillation process is to produce a number of tar acid products from the crude tar. The number of fractions, and size of fractions etc., which are to be taken off when tar is distilled is dependent on so many factors. The quality of tar plays a big part. Also, the kind of plant available for distillation is an ...

LONDON(BUSINESS WIRE)The global coal tar market is expected to post a CAGR of nearly 2% during the period, according to the latest market research report by .
Coal tar is essentially the thick viscous liquid which is obtained by the carbonisation of coal, and is a byproduct in the ordinary manufacture of coal gas. It should be differentiated from all the other forms of tar. When coal is submitted to dry distillation in horizontal or vertical retorts, the products of carbonisation are gas, ammoniacal ...
This removes moisture, Naphthalene, light creosote oil and heavy creosote oil from The coal tar. The resultant product is called coal tar Pitch. Depending on the blend of crude coal tar and the Temperatures to which the distillation is carried out Different grades of coal tar pitch are produced.
