ABSTRACT:
A heating and drying process for dedusting heavy oil derived from solid hydrocarbon-containing material, such as oil shale, coal or tar sand, without the use of diluents, solvents, chemical additives or mechanical separators, such as centrifuges and filters. In the process, heavy oil is fed to a dryer, such as a screw conveyor dryer or fluid bed dryer, and separated into a dedusted stream of oil and a powdery, dust-enriched residual stream. Preferably, heavy oil residue in the residual stream is combusted to leave a spent stream for use as heat carrier material in both the dryer and retort.
