Abstract: A system is described for treating diluted bitumen product underflow from known solvent recovery units in the oil sands processing, the system comprising vertically spaced trays capable of providing isolated countercurrent flow of liquid bitumen for recovery as bitumen product and residual solvent vapors evaporated therefrom. Each tray comprises a pool portion for receiving the diluted bitumen in shallow liquid pools having a surface area for enhanced evaporation of the solvent therein, and a transport portion for directing the liquid along a flow path for mixing the liquid and bringing more solvent to the surface, while minimizing re- contact between the solvent vapors and the liquid bitumen.

Abstract: A method for operating a multi-stage FSU system in the event that a second or subsequent FSU in the system is not operating to specification, so that operators may remedy the problem without shutting down the entire system and while maintaining a desired solvent to bitumen ratio. In the method, solvent that is normally added to the underflow stream recovered from an FSU in the system and delivered to a second or subsequent FSU, is redirected either in whole or in part, around the second or subsequent FSU. This redirected solvent is added to the multi-stage FSU system downstream of the second or subsequent FSU, thereby maintaining the solvent to bitumen ratio and enabling the multi-stage FSU system to operate until the problem with the second or subsequent FSU is resolved.

Abstract: An oilsands extraction, tailings solvent recovery process, employs a recovery vessel that is free of internals. A tailings feedstream is distributed for falling as fluid envelopes through the vessel. One or more steam jets are arranged in layers along a height of the vessel and arte directed at high velocity into the fluid envelopes, disrupting the feedstream for enhanced vaporization of solvent therefrom. The steam can be discharge from one or more axially spaced steam modules located in the vessel, the fluid envelopes flowing in an annulus formed thereabout. A majority of the solvent is recovered from the disrupted feedstream without internals and thus substantially free of asphaltene fouling, and without the need for maintaining a liquid pool other than to maintain outlet operability.

Abstract: A system and method is described for separating solvent from a solvent-diluted bitumen feedstream from oil sands froth treatment processing. A distillation tower receives a first feedstream portion intermediate the tower at or above the solvent bubble point and a second feedstream portion at an upper end of the tower at temperature at about or lower than the dew point of bitumen. A bitumen liquid product is recovered from a tower bottom and a solvent product is recovered from an upper end as recycle solvent to the upstream froth treatment process. Prior to splitting into first and second portions, the feedstream may be flashed, the underflow forming the tower feedstream while the overhead vapor is available directly as recycle solvent. The two feedstream portions and temperatures thereof enable solvent recovery without the use of a reflux or a bottom reboiler.

Abstract: Froth settling vessels (FSU) taught herein utilize a classifier feedwell to pre-classify a solvent diluted feedstream into a less dense bitumen and solvent overflow and a more dense water, solids and asphaltene agglomerate underflow. The overflow and underflow are discharged into the FSU at axially spaced apart locations, forming a substantially non-turbulent interface therebetween. The majority of the bitumen and solvent in the overflow rises to the top, following discharge above the interface, and the majority of the dense components fall to the bottom, following discharge below the interface. Minor amounts of less dense components in the underflow and more dense components in the overflow rise and fall substantially unimpeded through the interface. The FSU can be operated at flux rates exceeding conventional FSU as the risk of breakthrough is minimized as a result of the pre-classification and discharge to discrete locations within the FSU.

Abstract: A process for polishing a dilbit product produced from a conventional paraffinic froth treatment process results in a polished dilbit product stream having minimal impurities, including water, mineral and non-mineral solids and water, therein. The dilbit product from a froth separation unit (FSU) is fed into a High G- force separator for removal of impurities therefrom. Typically, the impurities in the initial dilbit product are less than about 0.5wt% and can be reduced as taught herein to at least an order of magnitude lower. Multiple stages of polishing can be performed.

Abstract: A bitumen-containing froth is treated with a paraffinic solvent by adding the froth to the solvent in two or more additions prior to separation in a froth settling unit. The first addition of froth results in an S:B ratio which causes precipitation of asphaltenes in the bitumen. Maltenes are dissolved in the solvent. The dissolved maltenes shift the solubility parameter of the solvent. The second or more additions of the balance of the froth to the shifted solvent result in an overall S:B ratio resulting in precipitation of the asphaltenes and dissolving of the maltenes. The volumes of the two or more additions of froth can be adjusted to meet different objectives. Solvent requirements can be reduced, a target asphaltene content in the final product can be altered or both. Further, the target asphaltene content in the product can be designed so as not to foul downstream heating processes.

Abstract: A method for temporarily bypassing an offline oilsand froth settling unit (FSU) of a multi-stage FSU system in the event of failure of the offline FSU while maintaining operability, maximizing separation performance and minimizing propagation of the disturbance to other systems. The offline FSU is isolated and the underflow stream of the remaining operational stage is split between a reject stream directing solids and water to a tailing solvent recovery unit and a solvent- enriched recycle stream for comingling with bitumen froth as a feedstream to the inlet to the operational FSU. Solvent addition stream is re-routed from interstage addition to bypass the reject tailings stream and join the recycle stream, aiding in continued FSU operation for separation of maltenes and solvent from rejected solids and water. Dilbit product is recovered from the online FSU.

Abstract: An apparatus and methodology for storing bitumen froth comprising a fluidized bottom, froth first feed holding tank for maintaining effective tank capacity while reducing overall solid bed build up at side walls and minimizing sloughing of solids to the froth discharge outlet. Froth is fed to the tank through one or more feed inlets located between the froth outlet and side walls for fluidizing settling solids. The feed inlets urge solids to settle in sub-beds about the feed inlets, the height of which that manifests adjacent the side walls being less that some design threshold height; if not, then successive feed inlets are located between the side walls and the precious feed inlets to build further sub-beds that have a height at the wall that is less than the threshold height.
