ABSTRACT:
Maximum removal of asphaltic material, including high molecular weight metallic contaminants, from a hydrocarbonaceous charge stock is achieved through the utilization of a solvent extraction zone provided with direct heating facilities in an upper portion thereof. A portion of the solvent-rich hydrocarbon phase is withdrawn from the extraction zone, increased in temperature and introduced into an asphalt settling zone. The separated solvent/hydrocarbon stream, substantially asphalt-free, is reintroduced into the extraction zone at the higher temperature.
