Abstract
An energy efficient process for separating a hydrocarbonaceous material into various fractions. The hydrocarbonaceous material is admixed with a solvent and the mixture is introduced into a first separation zone maintained at an elevated first temperature and pressure. The feed mixture separates into a first light phase comprising solvent and at least a portion of the lightest hydrocarbonaceous material and a first heavy phase comprising the remainder of the hydrocarbonaceous material and some solvent. The first heavy phase is introduced into a second separation zone maintained at a second temperature level above the first temperature level and at an elevated pressure. The first heavy phase separates into a second light phase comprising solvent and a second heavy phase comprising at least a portion of the hydrocarbonaceous material. The separated hydrocarbonaceous material fractions are recovered.
