ABSTRACT OF THE DISCLOSURE A method for dewatering tar-water mixtures obtained from the coking of coal is disclosed. The method involves adding to the tar from 150 to 4,000 ppm of a di-tri butyl ethoxylated phenol compound dissolved in water, heating the tar-water mixture, and then agitating it to allow contact with the chemical additive. This is followed by allowing the mixture to settle forming an aqueous upper phase and a lower dewatering tar phase.
