    摘要: The present invention relates to a process for improving a deasphalting unit process by producing an improved feedstream for the deasphalting process via ultrafiltration of a vacuum resid-containing feedstream. In particular, the present invention produces an improved quality feedstream to a solvent deasphalting process which results in improved deasphalted oil (DAO) production rates and/or higher quality deasphalted oils. The present invention can be particularly beneficial when used in conjunction with an existing deasphalting equipment to result in improved deasphalted oil (DAO) production rates and/or higher quality deasphalted oils from the existing deasphalting equipment without the need for significant equipment modifications to the existing deasphalting unit.

    摘要: 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.
