摘要： Methods for transporting bitumen extraction product include providing bitumen-laden aromatic solvent, providing bitumen-laden paraffinic solvent, and blending the two materials. The resulting mixture can be transported through existing pipeline infrastructure and can use existing separation processing equipment, and thereby avoids the need for separate infrastructure for each composition. Combining the two compositions can also avoid undesirable asphaltene precipitation.

摘要： Embodiments of a method and a system for recovering energy, materials or both from asphaltene-containing tailings are disclosed. The asphaltene-containing tailings can be generated, for example, from a process for recovering hydrocarbons from oil sand. Embodiments of the method can include a flotation separation and a hydrophobic agglomeration separation. Flotation can be used to separate the asphaltene-containing tailings into an asphaltene-rich froth and an asphaltene-depleted aqueous phase. The asphaltene-rich froth, or an asphaltene-rich slurry formed from the asphaltene-rich froth, then can be separated into a heavy mineral concentrate and a light tailings. Hydrophobic agglomeration can be used to recover an asphaltene concentrate from the light tailings. Another flotation separation can be included to remove sulfur-containing minerals from the heavy mineral concentrate. Oxygen-containing minerals also can be recovered from the heavy mineral concentrate. Water removed by the various separation steps can be recycled and its heat energy recovered.

摘要： A method of extracting bitumen from bituminous material. In some embodiments, the method may include loading a bitumen material in a column, followed by feeding a first quantity of solvent into the column. The method may also include collecting the bitumen-enriched solvent exiting the column. A quantity of the bitumen-enriched solvent may then be fed into the column. In some embodiments, the method may include simultaneously loading bitumen material and a solvent in a column, followed by feeding additional solvent into the column. The method may also include collecting bitumen-enriched solvent exiting the column, and feeding a quantity of the bitumen-enriched solvent into the column.

摘要： A process for separating bitumen from bitumen ore material includes extracting bitumen with a hydrocarbon solvent to produce a bitumen-enriched solvent phase and tailings. The tailings are dried or stripped in a dryer to remove any remaining hydrocarbon solvent. The amount of solvent discharged in the tailings may be less than 4 bbl per 1000 bbl of recovered bitumen.

摘要： Methods for preparing solvent-dry, stackable tailings. The methods may include a primary leaching or extraction process that separates most of the bitumen from a material comprising bitumen and produces first solvent-wet tailings. The first solvent-wet tailings are washed with a second solvent that removes the first solvent from the tailings. Second solvent remaining in the tailings is removed to thereby produce solvent-dry, stackable tailings.
