Process for deasphalting an asphaltene containing hydrocarbon charge

摘要

Process for deasphalting an asphaltene-containing hydrocarbon charge wherein said charge, admixed with a first fraction of light paraffinic hydrocarbon solvent, is passed through an elongate zone inclined by 2 DEG to 15 DEG to a horizontal line while a second fraction of light paraffinic hydrocarbon solvent is introduced at one or more points of the lower half of said elongate zone, downwardly in an angle from 10 DEG to 80 DEG with the main axis thereof oriented in the direction of flow of the mixture, and wherein the upper phase of deasphalted oil and the lower asphalt phase are separately withdrawn, the light hydrocarbon being separated from each of these phases.
