Crude Naphthalene, Refined Naphthalene, Creosote Oil, Coal Tar Pitch, Carbon Black Oil from European Coal Tar Distiller having capacity of distillation over 120'000Mts of coal tar per annum.
For vacuum distillation of crude coal tar, (specifically creosote oil), the crude coal tar is produced from coke ovens of steel plant, 50% of this crude coal tar in pitch. Coal tar is essentially the thick & black viscous liquid which is obtained by the carbonization of coal, and is a by product in the ordinary manufacture of coal gas.
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 ...

COAL-TAR, the black, viscous, sometimes semi-solid, fluid of peculiar smell, which is condensed together with aqueous "gas liquor" when the volatile products of the destructive distillation of coal are cooled down. It is also called "gas-tar," because it was formerly exclusively, and even now is mostly, obtained as a by-product in the manufacture of coal-gas, but the tar obtained from the ...
Anthracene, Cresol, Crude tar, Dehydration, HBTA, Hydrocarbons, Phenol, tar, tar distillation, 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 .
Coal-tar 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 coal-tar pitch contain many chemical compounds, including carcinogens such as benzene.
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 ...
The tar may be fractionated to yield creosote, oils, and pitch. Hardwood tars are obtained from pyroligneous acid, either as a deposit from the acid or as a residue from the distillation of the acid. Crude pyroligneous acid is the condensed, volatile product of wood distillation.
Crude Coal Tar Distillation Plant Suppliers. 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.
Many of the specifications first published in England state that the distillation of the sample is to be carried out under conditions similar to those employed in the distillation of crude coal tar on a large scale; namely, the immersion of the bulb of the thermometer in the oil during the distillation and taking account of the amount of the ...
Coal tar creosotes are distillation products of coal tar; Unlike the coal tars and coal tar creosotes, coal tar pitch is a residue produced during the distillation of coal tar; Creosote production falls into two categories: distillate ( creosote), and creosote in coal tar solution.
Coal-tar creosote is a brownish black/yellowish dark green oily liquid with a characteristic sharp odor, obtained by the fractional distillation of crude coal tars. The approximate distillation range is 200–400°C as reported in the general public literature.
Creosote is obtained from high temperature distillation of coal tar (itself a mixture of hundreds of organic substances). Read more here. Creosote Treatment Process. Coal-tar creosote is the most widely used wood treatment today; both industrially, processed into wood using pressure methods such as "full-cell process" or "empty-cell process."
Coal Tar Creosote Oil used for wood preservation and for vacuum pressure wood treatment in particular creosote is controversially valued. Thus, although creosoted wood has acknowledged harmful human health effect and environmental impact, nevertheless no other wood treatment chemical can substitute Creosote's durable and strong quality effect.
Laser-desorption mass spectrometry (LD-MS) method development was undertaken to improve estimates of mass ranges for complex hydrocarbon mixtures. A creosote oil, an anthracene oil, and a mixture of known polynuclear aromatic hydrocarbon (PAH) compounds were examined. The data on the mixture of the four PAHs made it possible to define LD-MS conditions necessary to generate artifacts such as ...
Refined tar is a complex mixture of high boiling organic compounds manufactured during the selective distillation of crude coke oven tar. Refined tars are processed into various specifications and are supplied as raw materials to independent manufacturers for a wide variety of end use applications.

Creosote is a complex mixture of aromatic and heterocyclic organic compounds obtained from the fractional distillation of coal tar. It has been used as a fungicide, insecticide, and sporicide. It has also been used extensively as a wood preservative in terrestrial and marine environments. Creosote wood preservatives are often used to pressure treat railroad ties/crossties and utility poles or ...

Coal tar is used in the production of substances such as creosote, crude naphthalene, and carbon black feedstock. Coal tar is used as an active ingredient in human and veterinary drugs, primarily in the form of shampoos used to treat skin conditions. This use is considered safe.
Production The complete process of coal tar production is shown in Figure 1 The coal tar is produced by carbonization of coal In this process, the coal is heated at 900-1100 ºC and the evolved vapors are condensed to form liquid, from which ammonia is removed to obtain a black viscous crude coal tar.
CAUTION: Coal tar and coal tar pitches are listed as known human carcinogens: Report on Carcinogens, Eleventh Edition (PB2005-104914, 2004) p III-68. Use: Prodn of creosote, coal tar pitch, crude naphthalene and anthracene oils; as fuel for furnaces in steel industry.
Coal-tar creosote, also referred to as creosote by the EPA, is formed by fractional distillation of crude coal tars. This compound is used as a wood preservative that acts as a fungicide and pesticide applied in a pressure treatment process, which involves pressurized treating cylinders that force pesticide penetration into the wood.
