Abstract

A process for separating solids from hydrocarbons in a slurry of hydrocarbonaceous solids and solvent is disclosed comprising atomizing the slurry, introducing and mixing the atomized slurry and superheated steam in a stripping zone, vaporizing the hydrocarbons, and separately removing the vapors and the solids. The process is particularly useful in an oil shale recovery process.
