Abstract
The invention provides a method of desulfurizing an oil composition, the method comprising: flowing an oil composition comprising sulfur through a conduit comprising a constricted region, wherein oil-phase bubbles form in the constricted region and collapse in a turbulent zone downstream of the constricted region; contacting the oil composition with an immiscible deep eutectic solvent in the turbulent zone, thereby extracting at least a portion of the sulfur from the oil composition into association with the deep eutectic solvent; and separating the deep eutectic solvent and the extracted sulfur from the desulfurized oil composition.
Claims20
A method of desulfurizing an oil composition, the method comprising:
- flowing an oil composition comprising sulfur through a conduit comprising a constricted region, wherein oil-phase bubbles form in the constricted region and collapse by hydrodynamic cavitation in a turbulent zone downstream of the constricted region;
- contacting the oil composition with an immiscible deep eutectic solvent in the turbulent zone, thereby extracting at least a portion of the sulfur from the oil composition into association with the deep eutectic solvent;
- and
- separating the deep eutectic solvent and the extracted sulfur from the desulfurized oil composition.
A system for desulfurizing an oil composition, the system comprising:
- a conduit comprising a constricted region;
- a pump for flowing an oil composition comprising sulfur through the conduit;
- and
- one or more injection ports for introducing a stream of deep eutectic solvent to the conduit;
- wherein the system is operable to:
- (i) flow the oil composition through the conduit such that oil-phase bubbles form in the constricted region and collapse by hydrodynamic cavitation in a turbulent zone downstream of the constricted region;
- and
- (ii) contact the oil composition with the deep eutectic solvent in the turbulent zone, thereby extracting at least a portion of the sulfur from the oil composition into association with the deep eutectic solvent.
