Abstract

A process and system for converting petroleum residue ("resid") into a liquid product and a solid product. The resid is first mixed with a solvent having a generally nonpolar molecular character. A strong electric field is then applied to the mixture to agglomerate the asphaltenes and other large molecules in the resid. The agglomerates are then separated from the remaining liquid, thereby producing liquid and solid products. The liquid product is useful as a feedstock for petrochemicals and transportation fuels, and the solid product is suitable for combustion as a coal substitute. A portion of the liquid product may be recycled as the solvent.
