ABSTRACT:
A tar sands slurry containing sand particles of varying sizes dispersed therein is passed into a classifier wherein it is subdivided into at least two streams, each stream containing either coarse or fine solids. The stream containing coarse solids is directed to a separate solids removal zone where the solids are removed. The effluent from the solids removal zone and the fine solid containing stream are then fed to a coking zone.
