Patent number: 7033486Abstract: The present invention relates to a process for increasing the capacity for processing residua and obtaining higher yields of liquids having an average boiling point equal to or less than about 510° C. A residual feedstock is introduced with recycled product asphaltenes into a short vapor contact time thermal process unit wherein the vaporized product is sent to a fractionator zone to produce a 510° C.? fraction and a 510° C.+ fraction. The 510° C.+ fraction is sent to a solvent extraction zone to produce an asphaltene-rich fraction that is recycled to the short vapor contact time thermal process unit.Type: GrantFiled: February 18, 2003Date of Patent: April 25, 2006Assignee: ExxonMobil Research and Engineering CompanyInventors: Martin L. Gorbaty, Michael Siskin, Mitchell Jacobson

Patent number: 6652739Abstract: An improved process for deasphalting a residua feedstock by use of a short vapor residence time process unit comprised of a horizontal moving bed of fluidized and/or stirred hot particles. The vapor phase product stream from said process unit is passed to a soaker drum where a high boiling fraction is separated and recycled to the process unit after undergoing reactions causing molecular weight growth. This reactive recycle using the soaker drum results in substantially improved qualities of the liquid products compared with what is achieved by once-through residua deasphalting process alternatives.Type: GrantFiled: October 29, 2002Date of Patent: November 25, 2003Assignee: ExxonMobil Research and Engineering CompanyInventors: Mitchell Jacobson, Willibald Serrand, Norman H. Sweed, Hans J. M. Weiss, Ingo W. Dreher, Udo Zentner, Jorg H. Schmalfeld
