  • Chemical products production in coal tar treatment plant

    Feb 18, 2014 Coal tar is a dark viscous material obtained as a byproduct during the process of destructive distillation of coal (to produce coke oven gas and coke). Hot coke oven gas from the battery is cooled to separate coal tar along with byproducts like phenol, light oil, washoil, anthracene, pitch and naphthalene.
