摘要： A process for regionalization of mining bitumen-containing oil sands ore for extraction and conversion to produce dry bitumen comprises operating multiple separate oil sands ore mining and extraction facilities or in situ thermal recovery facilities, to produce separate bitumen froth streams; operating a regional paraffinic froth treatment (PFT) hub for receiving a portion of each of the separate bitumen froth streams and treating the bitumen froth streams to produce the dry bitumen; optionally providing a portion of the dry bitumen stream to the bitumen upgrading facility and another portion of the dry bitumen stream to a bitumen market pipeline or remote upgrading facility; and optionally comprising regionalization of water distribution where by-product waters are recovered from the PFT hub and the upgrading facilities and distributed to the mining and extraction facilities for use as extraction processing water to produce the bitumen froth streams.

The separation apparatus includes a vessel, a tailings outlet, a solvent outlet, a tailings inlet for supplying a variable flow of the tailings to the vessel and a tailings recycle line connected to the tailings inlet for recycling part of the solvent recovered tailings into the variable flow of the diluted tailings to produce a flow rate controlled feed for introduction into the vessel. A tailings solvent recovery process includes separating the diluted tailings into recovered solvent and solvent recovered tailings, discharging the solvent recovered tailings, and recycling a portion of the solvent recovered tailings back into the variable flow of the diluted tailings. A method of controlling feed flow rate to a tailings solvent recovery vessel is also provided.

摘要： 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 Co V, 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.

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.
