ABSTRACT:
An improved coal processing system wherein a feed mixture (including coal, dissolving solvent, insoluble coal products and soluble coal products) at a first temperature level is separated in a first separation zone into a heavy fraction including the insoluble coal products and a light fraction and, thereafter, the heavy fraction is withdrawn from the first separation zone and heated to a second temperature level higher than the first temperature level and in which the second temperature level is sufficiently high to produce a heavy fraction that is flowable.
