Abstract: The field of the invention is oil sands processing. A solvent treatment system and process for treating a bitumen-containing stream include contacting that stream with a solvent-containing stream to produce an in-line flow of solvent diluted material; supplying the solvent diluted material into a separation vessel with axi-symmetric phase and velocity distribution and/or particular mixing and conditioning features. The solvent addition, mixing and conditioning may be performed with particular CoV, Camp number, co-annular pipeline reactor, pipe wall contact of low viscosity fluid, flow diffusing and/or flow straightening. The processes enable improved performance of downstream unit operations such as separation of high diluted bitumen from solvent diluted tailings.

Abstract: A solvent diluted bitumen is produced by a method that includes adding paraffinic solvent to bitumen froth to form a solvent diluted bitumen froth, and discharging the solvent diluted bitumen froth into a vessel, such that settlement of the solvent diluted bitumen froth in the interior of the vessel establishes a heavier phase zone, a lighter phase zone, and an interface. A discharge point is located above the interface and within the lighter phase zone. Lighter phases separate up toward an overflow outlet of the vessel while heavier phases separate down toward an underflow outlet of the vessel. The solvent diluted bitumen is collected from the overflow outlet, and a solvent diluted underflow stream is collected from the underflow outlet.

Abstract: An apparatus and method for separating a feed such as bitumen froth feed are provided. The apparatus comprises a vessel having a top, side walls, and a base. An inlet delivers feed to the vessel interior whereby settling of the feed establishes a heavier phase zone in the vicinity of the base and a lighter phase zone above an interface with the heavier phase zone. The height/diameter ratio of the vessel, the dimensions and position of the inlet and the fluid properties of the feed are selected to allow a feed velocity of the feed discharging from the inlet into the interior to dissipate in the lighter phase zone as the discharged feed entrains lighter phases above the interface and spreads across the vessel interior such that the lighter phases of the feed separate up to an overflow outlet and the heavier phases separate down to an underflow outlet.

Abstract: A method of delivering feed, for example a paraffinic solvent treated bitumen froth, to a separation vessel, for example a froth separation unit (FSU). The feed is delivered from one or more side inlets that may be substantially normal to, and flush with, the wall of the vessel. In contrast to certain conventional feed systems used in gravity separators which use a distributor plate to widely distribute the feed with a vessel, the feed is delivered such that it flows down the inside wall of the vessel. This feed delivery is characterized by a Richardson number of greater than 1.0. Such feed delivery is particularly useful where the feed has particles with a bi-modal size distribution to be separated from an overflow stream. The gentle flow serves to mitigate the upward flux of the smaller particles, for example mineral solids, by being trapped below the larger particles, for example precipitated asphaltene aggregates.

Abstract: A separation process and system for extracting hydrocarbons from a mixture. In some embodiments, a process for separating a bitumen froth stream containing bitumen froth, water and fine solids into a bitumen enriched froth stream and a water and fine solids stream, comprises: (a) receiving the bitumen froth stream in a concentrator vessel, (b) distributing the bitumen froth stream in the concentrator vessel as a substantially uniform and generally horizontal flow of the bitumen froth stream at a first flow velocity, (c) slowing the bitumen froth stream to a second flow velocity, slower than the first flow velocity, in a separation region of the concentrator vessel to promote separation of the bitumen froth from the water and fine solids, and then (d) collecting a bitumen enriched froth stream and (e) collecting a separate water and fine solids stream. Related embodiments of systems and apparatus may also be provided.

Abstract: An extraction system and process for extracting bitumen from a slurry containing bitumen, solids and water. The system comprises a cyclone separation facility for separating the slurry into a solids component stream and a bitumen froth stream with the bitumen froth stream including water and fine solids. The bitumen froth stream is then delivered to a froth concentration facility for separating the bitumen froth stream into a final bitumen enriched froth stream, and a water and fine solids stream. The final bitumen enriched froth stream is suitable for further processing. The system of the present invention is preferably mobile so that the cyclone extraction facility and the froth concentration facility can move with the mine face at an oil sands mining site, however, it is also contemplated that the system can be retrofitted to existing fixed treatment facilities to improve the operational efficiency of such fixed facilities.
