Distillation In Coal Mining Industry 25/7/2019 · Few industries are more dependent on distillation than that of coal tar. It was in consequence of a discovery by Bethel in 1838 that it was realised that valuable products'could be obtained from coal tar by submitting it to distillation.
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.
⇒ Diversified and good recognized basic properties of coal tar allow you to compose the batch to distillation process for obtaining a coal tar pitches with assumed properties depending on the application ⇒ An important factor affecting the properties of the produced coal tar pitches is an appropriate choice of technological
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. It may be applied to the affected area 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.

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.
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.

Coal Tar Distillation Products - Pitch is derived from the process of coal Tar at high temperature using the latest technology under strict process and quality control. The salient features are - (a) Low Volatile content (b) High fixed carbon (c) Low ash content (d) No mesophase (e) Good wettability
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. Get Free Quote
products that are coal-tar based typically contain 20 to 35 percent coal-tar pitch. Being flammable, coal tar is sometimes used for heating or to fire boilers. Like most heavy oils, it must be heated before it will flow easily. Coal tar is also used to manufacture paints, synthetic dyes, and photographic materials.
