VACUUM DISTILLATION OF CRUDE COAL TAR

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. Coal tar is produced by the dry distillation of coal and is therefore a by product in the manufacture of coal gas.

Value-added utilization of high-temperature coal tar:

Abstract. High-temperature coal tar (HTCT) is an important raw material for obtaining value-added aromatics. However, effective utilization of HTCT is not optimistic because of backward processing technology and higher energy consumption, resulting in fewer product types and lower purity. Accordingly, value-added utilization (VAU) of HTCT should be ...
