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： Methods for preparing solvent-dry, stackable tailings. The method can include the steps of adding a first quantity of first solvent to a bitumen material to form a first mixture, separating a first quantity of bitumen-enriched solvent from the first mixture and thereby creating first solvent-wet tailings, adding a quantity of second solvent to first solvent-wet tailings to separate a first quantity of first solvent component from the first solvent-wet tailings and thereby producing second solvent-wet tailings, and adding a quantity of water to the second solvent-wet tailings to separate a first quantity of second solvent component from the second solvent-wet tailings and thereby forming solvent-dry, stackable tailings.

摘要： Methods for obtaining bitumen from bituminous material. The methods may include a dissolution step where a first solvent is added to material comprising bitumen to dissolve the bitumen contained therein. The majority of the dissolved bitumen is then removed from the mixture of first solvent and material comprising bitumen by filtering or settling the mixture of first solvent and material comprising bitumen. Any residual dissolved bitumen is then removed from the mixture of first solvent and material comprising bitumen by adding additional first solvent to the mixture to displace the residual dissolved bitumen from the mixture.

摘要： A method for processing asphaltenes is disclosed. The method can include separating asphaltenes from an asphaltene-containing composition and oxidizing the separated asphaltenes to form oxidation products. Alternatively, the method can include oxidizing asphaltenes within an asphaltene-containing composition without first separating the asphaltenes. Once formed, the oxidation products can be combined with other hydrocarbons. The amount of oxidation can be limited to an amount sufficient to produce a mixture suitable for the desired application. This method can be used to upgrade asphaltenes from a variety of sources, including oil sands. The oxidation step can be performed, for example, by introducing an oxidizing agent and, in some cases, a catalyst into the asphaltenes. A solvent or miscibility agent also can be introduced to improve mixing between the oxidizing agent and the asphaltenes.

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.

In some embodiments, the method may include simultaneously loading bitumen material and a first solvent in a column, followed by feeding additional first 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.
