摘要： A paraffinic solvent recovery process for treating high paraffin diluted bitumen includes supplying the latter to flashing apparatus; separating into flashed paraffinic solvent and diluted bitumen underflow; and returning a portion of the underflow as returned diluted bitumen into the high paraffin diluted bitumen prior to introduction into the flashing apparatus, at temperature and amount to shift asphaltene precipitation equilibrium to reduce asphaltene precipitation. The process includes pre-heating the high paraffin diluted bitumen by transferring heat from hot dry bitumen, flashed paraffinic solvent and/or a portion of diluted bitumen underflow. Flashed paraffinic solvent may contain residual light end bitumen contaminants that increase asphaltenes solubility and the process may include removing contaminants to produce reusable paraffinic solvent at given solvent-to-bitumen ratio range to maintain given asphaltene precipitation. The process may also include a bitumen fractionation column producing hot dry bitumen underflow containing at most 0.5 wt % paraffinic solvent.

摘要： A heat and water integration process for an oil sands operation includes subjecting warm oil sands tailings to thickening to produce thickened tailings and warm water overflow; subjecting the warm water overflow to direct steam injection (DSI) to produce steam heated thickener water; providing the steam heated thickener water to a unit of the oil sand operation; and producing the warm oil sands tailings from the oil sands operation. The oil sand operation unit may be an oil sand ore preparation unit and/or a primary separation unit, for example. The heated thickener water can replace water taken from pond inventories. The DSI may use excess, low quality, wet, low pressure and/or blow-down steam. The process enables improved heat and water usage in oil sands processing.

摘要： In the field of oil sands processing, a process for heating an oil sands slurry stream such as bitumen froth containing bitumen and water and having variable heating requirements includes injecting steam directly into the froth at a steam pressure through a plurality of nozzles to achieve sonic steam flow; operating the plurality of the nozzles to vary steam injection by varying a number of the nozzles through which the injecting of the steam occurs in response to the variable heating requirements; and subjecting the oil sands slurry stream to backpressure sufficient to enable sub-cooling relative to the boiling point of water. A corresponding system is also provided.

摘要： 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.

摘要： A system and process for recovering heat from a bitumen froth treatment plant use a sealed closed-loop heat transfer circuit. The system has a heat removal exchanger associated with the plant and receiving hot froth treatment process stream; heat recovery exchanger; the circuit; and an oil sands process fluid line. The circuit includes piping circulating heat exchange media having uncontaminated and low fouling properties. The piping includes a supply line to the heat removal exchanger and a return line for providing heated media to the recovery exchanger. The circuit has a pump for pressurizing the heat exchange media; a pressure regulator for regulating pressure of the media. The pump and the pressure maintain the media under pressure in liquid phase. The oil sands process fluid is heated producing a cooled media for reuse in the heat removal exchanger. High and low temperature heat removal exchangers can be used.

摘要： Techniques provided herein relate to regulating at least one operating parameter of a paraffinic froth treatment (PFT) operation and controlling the quality of the produced bitumen in response to a determined concentration of at least one residual metal in a PFT process stream. Determination of the residual metal concentration is based on acquired NIR spectral measurements of the PFT process stream. An alkaline agent dosage in primary extraction operation can be for example regulated in response to a difference between a determined calcium concentration and a calcium concentration specification.

摘要： A process for operating a bitumen froth treatment operation in turndown mode includes adding solvent to bitumen froth to produce diluted bitumen froth and separating it into diluted bitumen and solvent diluted tailings and in response to a reduction in bitumen froth flow recirculating part of the diluted bitumen into the bitumen froth and returning part of the solvent diluted tailings into the step of separating. A method for turndown of separation vessel for PFT includes sustaining the feed flow to vessel; maintaining solvent-to-bitumen ratio in the diluted bitumen froth; and retaining water, minerals and asphaltenes in a lower section of the vessel while sustaining an outlet flow. The use of diluted bitumen derived from PFT as a viscosity modifying agent of the bitumen froth and an associated process are also provided.
