Coal Tar and its Distillation Processes – IspatGuru

2018-12-26  Distillation of coal tar is carried out mainly to produce benzols, naphtha, creosotes, naphthalene, anthracene, carbolic and cresylic acids, pyridine and pitch. The purpose of tar distillation is to (i) dehydrate the tar in the dehydration column, (ii) remove the pitch from dehydrated tar in pitch column and (iii) separate tar oils in fractionating column.

Flow diagram of coal to coal-tar-pitch process

2021-5-7  Coal tar is a byproduct of the coking, liquefaction, or gasification of coal. Coal-tar pitch is the residue that remains after the distillation of coal tar. Coal tar and coal-tar pitch are used in coal-tar-based sealcoat products, although use of coal-tar pitch is more common than use of coal tar. Both coal tar and coal-tar pitch are known human carcinogens. Learn more about coal-tar-based sealcoat here. Details

Project Report on coal tar distillation, Feasibility ...

coal tar distillation (eiri-1092) Coaltar is produced by the dry distillation of coal and is therefore a by product in the manufacture of coal gas. For a considerable time after the discovery of coal gas, the tar produced was considered merely an encumbrance and was used mainly as a pigment or fuel.

Coal Tar Pitch Distillation - Manufacturing Plant ...

Coal tar is also used to manufacture paints, synthetic dyes and photographic material. Like pine tar, it can be used in medicated shampoo, soap and ointment, as a treatment for dandruff, as well as being used to kill and repel head lice. The first coal chemical recovery ovens were installed in U.S. in 1893. There is a lot of demand for coal tar at present and the supply deficit is very high.
