Abstract:
1. A novel process configuration process for converting heavy oil or bitumen feedstocks to transportable synthetic crude oil comprising: a) feeding a bitumen or heavy oil feedstock having an API gravity of less than 15°, sulfur content greater than 3 weight %, and a vacuum residue content of greater than 35%, to a crude still to provide an atmospheric residue stream, a straight run atmospheric gas oil stream, and diluent stream; and b) feeding a portion of said atmospheric residue stream to a vacuum fractionator to create a vacuum residue stream and a straight run vacuum gas oil stream, bypassing a second portion of said straight run atmospheric residue from further processing, and bypassing a third portion of said straight run atmospheric residue for processing in a solvent deasphalter; and c) feeding said vacuum residue stream along with said third portion of said atmospheric residue stream to a solvent deasphalter to produce a deasphalted oil stream and an asphaltene stream; d) feeding a portion of the deasphalted oil stream and a hydrogen stream to a ebullated-bed reactor system to create a full-range liquid conversion product stream and a recovered butanes stream and bypassing the remaining portion of said deasphalted oil stream from further processing; and e) blending said full-range liquid conversion product stream, said bypassed portion of the deasphalted oil stream that was not further processed in step d) above, said bypassed second portion of the atmospheric residue stream, said straight run vacuum gas oil stream, said recovered butanes stream and said straight run atmospheric gas oil stream to create a synthetic crude oil.
