Retorting process
Fines in the overhead vapors from an oil shale retort process in which fresh shale together with hot recycle combusted shale from a combustor are fed to a retort and at least partly fluidized by a countercurrent stripping gas stream are handled by removing a portion of the fines in a vapor-solid separation optionally subjecting the portion of fines to additional retorting in a fines retort condensing the partially dedusted gas separating the condensate into a substantially finesfree liquid oil and a wet solids and recycling at least a portion of the wet solids to the retort, fines retort, and/or combustor whereby the liquid on the wet solids is recovered and/or burned and the wet solids are dried.
