Tar and Liquor Plant Conclusion WHAT IS IT AND WHAT DOES IT DO? The coke oven by-product plant is an integral part of the by-product cokemaking process In the process of converting coal into coke using the by-product coke oven, the volatile matter in the coal is vaporized and driven off This volatile matter leaves the coke oven chambers
Destructive distillation The process of pyrolysis conducted in a distillation apparatus to allow the volatile products to be collected An example is tar making from pinewood slices (which are rich in terpenes), which are heated in an airless container causing the material to decompose, leaving charcoal and turpentine as by-products
coal tar By-product from the manufacture of coke Coal tar comes from bituminous coal used in the distillation process It is a volatile substance, important for its organic chemical constituents (coal-tar crudes), which are extracted by further distillation
Coal Tar Distillation Coal tar pitch is the residue from the distillation of coal tar and represents from 30% to 60% of the tar It is a complex, bituminous sub- stance and has been estimated to contain about 5,000 compounds Of these, less than 130 have been isolated and identified The present-day process for fractionating coal tar .

5 PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL Table 5-1 lists the number of facilities in each state that manufacture or process coal tar creosote, the intended use, and the range of maximum amounts of creosote that are stored on site The data listed in Table 5-1 are derived from the Toxics Release Inventory (TRI) (TRI99 2001)
Coal Tar Distillation Coal tar is produced as result of high temperature carbonization and is a viscous dark brown product with characteristic odour and consists of about 300 different products some of the major constituents are the aromatics and heterocyclic compounds; benzene, toluene, xylene, phenol
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 ,
Crude Coal Tar is a by product of the Coking process Coking is the process of heating coal in coke ovens to drive volatile matter from it Metallurgical Coke is used as a fuel and reducing agent in the production of iron, steel, ferro-alloys, elemental phosphorus, calcium carbide and

Coke Manufacturing Industry Description and Practices Coke and coke by-products, including coke oven gas, are produced by the pyrolysis (heating in the absence of air) of suitable grades of coal The pro-cess also includes the processing of coke oven gas to remove tar, ammonia (usually recovered as ammonium sulfate), phenol, naphthalene, light
Product Stewardship Summary Coal Tar Pitch (CAS number 65996-93-2) (EC number 266-028-2) 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
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 coke-oven installations) of surplus gas, which permits of very delicate heat control
Pitch products are produced by Rain Carbon Inc from coal tar pitch (CTP), a derivative of coal tar distillation, as well as from specialty petroleum feedstocks CTP is mainly used as a binder for the production of carbon anodes essential for aluminum smelting
Coal tar is essentially the thick viscous liquid which is obtained by the carbonisation of coal, and is a by-product 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 .
OCCUPATIONAL EXPOSURES DURING COAL-TAR DISTILLATION 11 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 prima-rily of a complex mixture of condensed-ring aromatic hydrocarbons
