    摘要: A tailings solvent recovery unit (TSRU) recovers a solvent from a solvent diluted tailings and includes a separation apparatus which has a flash vessel, tailings outlet, solvent outlet and an inlet spray system for supplying the diluted tailings to the flash vessel. The spray nozzle system may include multiple nozzles arranged around the periphery of the flash vessel for flash-atomization over its cross-section of the flashing chamber, a nozzle sized and configured to provide choked flow of the diluted tailings, multiple nozzles each being operable in an on/off mode to regulate a total feed flow, or multiple nozzles associated with a distributor and multiple feed conduits.

    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: A method for pre-treating bitumen froth for mixing with solvent for froth treatment includes heating the froth to a froth-solvent mixing temperature below the solvent flash temperature and suitably high to provide reduced bitumen viscosity sufficiently low for complete mixing of the solvent and the froth prior to introduction into a separation apparatus. A method of improving energy use in froth treatment includes reducing heat provided to the solvent, increasing heat provided to the froth prior to adding the solvent to reduce bitumen viscosity and adding the temperature-reduced solvent to the heated froth. A froth treatment separation process includes trim heating first and second solvent streams to adjust the first and second stage separation temperatures.

    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: More particularly, the model was a dynamic simulation built in HYSYS™ v7.1. The component slate was simplified and selected to give a vapor and two liquid phases, and have the ability to measure an S/B ratio. All the unit operations were included and modeled as best fit within HYSYS™. Pumps were all modelled as standard HYSYS™ centrifugal pumps with performance curves, settlers were modelled as vertical 3-phase vessels with internal weir enabled—the overflow side of the weir is used to simulate the overflow vessels on the settlers. All proposed controllers were included with generic tuning parameters, which control the system process variable (PV) to match a set point (SP). The control algorithm incorporated master PV controllers such as S/B ratio to relate froth and solvent flows and maintain relative material balance relationship between the process streams involved. In this specific simulation, the solvent flows were assigned a slave relationship relative to the bitumen flow; that is, the solvent controller SP was reset based on the bitumen froth flow and the master S/B ratio.

    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.
