Abstract

A process for the simultaneous deasphalting and solvent extraction of an asphalt-containing mineral oil is performed by contacting the oil with a solvent comprising N-methyl-2- pyrrolidone (NMP) containing from 0-5 LV% water and a light hydrocarbon in a combination zone (12) to produce a raffinate and extract phase, with the raffinate phase containing the desired oil, most of the hydrocarbon solvent and some NMP. The raffinate is then passed to a reduced pressure flash zone (28) to remove most of the hydrocarbon solvent therefrom. The remaining raffinate oil and NMP solution is then chilled (e.g. in cooler 34) to produce bulk liquid-liquid immisicibility between the oil and NMP. The chilled oil and NMP are then passed to a settling zone (38) wherein an NMP- rich phase is separated from an oil- rich phase and recycled back into the combination zone (12). <IMAGE>
