    摘要: Processes and systems are described for solvent extraction of bitumen from oil sands. Fines agglomeration is employed to simplify subsequent separation. A high quality bitumen product can be formed, which meets or exceeds downstream processing and pipeline requirements. An embodiment comprises combining a first solvent and a bituminous feed to form an initial slurry, which is optionally separated into fine solids and coarse solids. Slurry solids are agglomerated. A low solids bitumen extract from the agglomerated slurry is mixed with a second solvent having a similar or lower boiling point than the first. The mixture is separated, solvent recovered, and a high grade bitumen product is formed. Exemplary systems comprise a mixbox, agglomerator, separator unit with optional countercurrent washer and deep cone settler, and TSRU. Processes are provided for fractionating a hydrocarbon fluid into heavier and lighter fractions. The lighter fraction may be used in solvent extraction of bitumen.

    摘要: The present disclosure relates to a method of processing a bituminous feed. The bituminous feed is contacted with an extraction liquor to form a slurry. The slurry is then flowed through a pipeline. A bridging liquid is added to the slurry to assist agglomeration. Agitation is also used to assist agglomeration. The result is an agglomerated slurry comprising agglomerates and a low solids bitumen extract. The agglomerates are then separated from the low solids bitumen extract. Performing the agglomeration in a pipeline as opposed to in a conventional agitating vessel may provide certain advantages, such as improved sealing in order to contain the potentially flammable mixture of oil sands slurry from the atmosphere, production of smaller and more uniform agglomerates due to improved mixing of the bridging liquid into the oil sands slurry, and the flexibility to have a long residence time for the extraction and agglomeration processes.

    摘要: A modified paraffinic froth treatment (PFT) process is described, in which a fine tailings stream obtained from a water extraction process practiced on oil sands is added during the treatment process. This modified process may be useful as a treatment for the fine tailings stream, allowing for the flocculation of the fines, thus reducing the volume of such fine tailings. The modified process may also be useful in that the fine tailings stream can be used as a supplement or a replacement for dilution water, thus eliminating or reducing the need for dilution water in the PFT process.

    摘要: A process is described for bitumen extraction from oil sands. Solvent extraction is used, incorporating fines agglomeration to simplify subsequent separation. A high quality bitumen product is formed, having water and solids content that exceeds downstream processing and pipeline requirements. An embodiment of the process comprises combining a first solvent and a bituminous feed to form an initial slurry, which is optionally separated into fine solids and coarse solids. Solids are agglomerated to form an agglomerated slurry. A low solids bitumen extract from the agglomerated slurry is mixed with a second solvent to form a solvent-bitumen low solids mixture, the second solvent having a similar or lower boiling point than the first solvent. The mixture is separated to produce high grade and low grade bitumen extracts. The first and second solvents are recovered from the high grade bitumen extract, leaving a high grade bitumen product.

    摘要: The present disclosure relates to a method of processing a bituminous feed. The bituminous feed is contacted with an extraction liquor to form a slurry. A bridging liquid is added to the slurry in at least two stages and solids within the slurry are agitated to form an agglomerated slurry comprising agglomerated solids and a low solids bitumen extract. The agglomerates are then separated from the low solids bitumen extract. Potential benefits may include the production of smaller and more uniform agglomerates. The former may lead to higher bitumen recoveries and the latter may improve the solid-liquid separation rate. The bridging liquid may be added in an area of relatively high shear rates. Between stages of bridging liquid addition, agglomerates may be removed.

    摘要: Methods and systems for recovering heat and water from waste streams produced during oil sands extraction to form dry, stackable tailings. A tailings stream is preheated in a heat exchanger, thereby reducing the energy required to dry the tailings. The preheated tailings are then dried, thereby reducing the tailings to dry stackable tailings or thickened tailings suitable for mine backfill. Heat and high-quality water are recovered from the drying operation and re-used in the preheat operation, or in other steps of oil sands extraction or treatment processes, thereby reducing the overall heat and water requirements.
