Abstract
This invention relates to an ultrafiltration process for separating a heavy hydrocarbon stream to produce an enriched saturates content stream(s) utilizing an ultrafiltration separations process. The enriched saturates content streams can then be further processed in refinery and petrochemical processes that will benefit from the higher content of saturated hydrocarbons produced from this separations process. The invention may be utilized to separate heavy hydrocarbon feedstreams, such as whole crudes, topped crudes, synthetic crude blends, shale oils, oils derived from bitumen, oils derived from tar sands, atmospheric resids, vacuum resids, or other heavy hydrocarbon streams into enriched saturates content product streams. The invention provides an economical method for separating heavy hydrocarbon stream components by molecular species instead of molecular boiling points.
