Abstract
According to one or more embodiments described herein, a method for processing a hydrocarbon feedstock may include contacting a mixed feed with a solvent in a deasphalting system to form residue and deasphalted oil, contacting the deasphalted oil with supercritical water to form an upgraded oil, separating the upgraded oil into at least a light fraction and a heavy fraction, and combining at least a portion of the heavy fraction with the hydrocarbon feedstock to form the mixed feed.
Claims20
A method for processing a hydrocarbon feedstock, the method comprising:
- contacting a mixed feed with a solvent in a deasphalting system to form residue and deasphalted oil;
- contacting the deasphalted oil with supercritical water to form an upgraded oil;
- separating the upgraded oil into at least a light fraction and a heavy fraction;
- and
- combining at least a portion of the heavy fraction with the hydrocarbon feedstock to form the mixed feed.
A system for processing a hydrocarbon feedstock, the system comprising:
- a deasphalting system configured to produce deasphalted oil and residue from a mixed feed stream;
- a supercritical water reactor system configured to produce an upgraded oil stream from the deasphalted oil, wherein the supercritical water reactor system is in fluid communication with the deasphalting system;
- a separator configured to separate the upgraded oil stream into at least a heavy fraction and a light fraction, wherein the separator is in fluid communication with the supercritical water reactor;
- and
- a mixing device configured to mix at least a portion of the heavy fraction with the hydrocarbon feedstock to form the mixed feed stream, wherein the mixing device is in fluid communication with the separator and the deasphalting system.
