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.
