Integrated Process For Complete Conversion Of Residue Feedstock

Abstract: The focus of this invention is the economic integration of two well-known technologies to provide an economical, integrated process unit for the complete conversion of residue feedstock. The technologies employed are heavy oil hydrocracking, which can be via an ebullated-bed, fixed-bed or slurry bed process, and coking, which can be via a delayed coking or fluid coking (with or without integrated gasification). The invention is most applicable to residue hydrocracking of high CCR and metals atmospheric and vacuum residues where coking of the unconverted hydrocracker residue is the most practical and economical method of hydrocracking bottoms disposal.
