Patent number: 8177965Abstract: 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.Type: GrantFiled: October 30, 2007Date of Patent: May 15, 2012Assignee: ExxonMobil Research and Engineering CompanyInventors: Daniel P.

Patent number: 7943037Abstract: A heavy residual petroleum feed boiling above 650° F.+ (345° C.+) is subjected to membrane separation to produce a produce a permeate which is low in metals and Microcarbon Residue (MCR) as well as a retentate, containing most of the MCR and metals, the retentate is then subjected to hydroconversion at elevated temperature in the presence of hydrogen at a hydrogen pressure not higher than 500 psig (3500 kPag) using a dispersed metal-on-carbon catalyst to produce a hydroconverted effluent which is fractionated to give naphtha, distillate and gas oil fractions. The permeate from the membrane separation may be used as FCC feed either as such or with moderate hydrotreatment to remove residual heteroatoms. The process has the advantage that the hydroconversion may be carried out in low pressure equipment with a low hydrogen consumption as saturation of aromatics is reduced.Type: GrantFiled: March 11, 2008Date of Patent: May 17, 2011Assignee: ExxonMobil Research & Engineering CompanyInventors: Martin L.
