Abstract

This invention relates to a process for producing a product stream with improved reduction of Conradson Carbon Residue (“CCR”) and a reduced average boiling point from a heavy hydrocarbon feedstream utilizing a high-pressure, low-energy separation process. The invention may be utilized to reduce the CCR content and reduce the average boiling point in heavy hydrocarbon feedstreams, such as whole crudes, topped crudes, synthetic crude blends, shale oils, bitumen, oil from tar sands, atmospheric resids, vacuum resids, or other heavy hydrocarbon streams. This invention also results in a process with an improved CCR separation efficiency while maintaining permeate flux rates.
