Process to remove asphaltene from heavy oil by solvent
Abstract:
Embodiments of the disclosure produce a method and system for deasphalting a hydrocarbon feed. The hydrocarbon feed and a first solvent is combined using a Taylor-Couette mixer to form a mixed stream. The mixed stream and a second solvent are introduced to an extractor to produce a first deasphalted oil stream and a pitch stream. The first deasphalted oil stream is introduced to a solvent recovery unit to recover the first solvent and the second solvent via a recovered solvent stream and to produce a second deasphalted oil stream.
