COAL TAR PITCH
(EIRI/EDPR/1357) J.C.127, 752
INTRODUCTION
Coal Tar Pitch
Coal tar pitch is a byproduct of turning coal into coke or coal gas. It is a sticky, dark brown or black liquid that resists flowing and has a very strong smell. In most cases, the volume of coal tar pitch used in medicinal preparations is very small in comparison to the amounts produced. As a result, most of the pitch is further processed to remove useful chemicals or is simply burned.
Coal Tar Pitch Manufacturing Process
Crude Coal Tar received from by-product coke oven plants is heated to temperatures up to 400oC in specially designed distillation stills. 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.
Coal Tar Pitch Manufacturing Equipment
In the coal crushing plant, coal crusher can resize the coal stone so that it can be easily handled and processed. Shenbang coal crusher is acknowledged in its field since long time and gives smooth running resulting power economy and higher efficiency.
Coal mill is not just one grinder mill, it will include some optional equipment such as vibrating feeder, vibrating screen, belt conveyors and so on to finish the coal milling process. So, coal mill is also used widely in many industries besides coal mining.
Coaltar is produced by the dry distillation of coal and is therefore a byproduct 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.
The purification of coaltar is affected by distillation. The crude tar, which contains a considerable quantity of ammonia water, is first freed from this by gravitation. It is then transferred to the vertical stills, which are connected with a warm surrounded with water which can be cooled or warmed as occasion requires. Distillation of the fraction boiling above 270oC is usually completed under reduced pressure.
