Abstract: A non-aqueous process for producing bitumen from oil sands is provided, and includes contacting oil sands and solvent to produce solvent diluted bitumen and solvent diluted tailings. The solvent diluted bitumen is subjected to a first fines separation stage that produces an overflow solvent diluted bitumen stream with residual fines that is subjected to a second fines separation stage to remove residual fines and produce a solvent diluted bitumen stream, which is subjected to solvent recovery. The fines streams are subjected to washing to produce washed tailings and solvent wash liquor comprising solvent and bitumen. Another non-aqueous process for producing bitumen from oil sands is provided, and includes subjecting oil sands to solvent extraction, including displacing the oil sands material and a solbit counter-currently and horizontally, and recovering a bitumen enriched solbit stream which is subjected to fines separation and subjecting the solvent diluted bitumen stream to solvent recovery.

Abstract: A non-aqueous extraction process for producing a bitumen product from an oil sands material that includes an ablation stage is provided. The ablation stage can include adding an ablation solvent to an oil sands material to achieve a solvent-to-ore ratio of less than about 10, mixing the ablation solvent and the oil sands material to reduce the size of the oil sands material and produce ablated ore that includes ablated ore fragments having a diameter of less than about 2 inches, and retrieving the ablated ore as a single stream. The ablated ore can be subjected to a reject separation stage to separate reject material therefrom. The reject material can also be subjected to a wash reject stage. The ablated ore can then be subjected to an extraction stage. Examples of ablators are also described, which can include for instance a conveyor, or can be a rotary screen ablator.

Abstract: A non-aqueous extraction (NAE) process for producing bitumen from oil sands ore can include a multistage bitumen extraction step where paraffinic solvent and deasphalted oil are added at a downstream stage of extraction at solvent-to-bitumen ratios below asphaltene precipitation onset threshold to remove bitumen from the solid mineral material, while the ore is added to a first stage to mix with the solvent-bitumen mixture and produce solvent diluted bitumen. The process includes recovering the solvent diluted bitumen and the solvent diluted tailings from the extraction step. The solvent diluted bitumen is subjected to deasphalting to produce solvent diluted deasphalted bitumen that is used as a source of the paraffinic solvent and deasphalted oil supplied to extraction. The tailings and asphaltene fraction from deasphalting can be subjected to washing and the washed material can then be subjected to sand solvent recovery. The NAE process can be operated within an operating envelop for effective and efficient performance.
