    摘要： Disclosed is a method of processing bitumen streams using membrane filtration. In one aspect, membrane filtration replaces paraffinic froth treatment, with one or more filtration steps replacing gravity settling. In another aspect, the bitumen stream is subjected to paraffmic solvent treatment at much higher flow rates, with an “almost cleaned” product being subsequently filtered by the membrane system. In this case, some contaminants are removed by conventional gravity settling equipment, while additional contaminants are removed by membrane filtration. In another aspect, membrane filtration is applied to a bitumen product effluent stream following naphthenic froth treatment. In another aspect, membrane filtration is applied to a bitumen product effluent stream from a solvent-based extraction process. In yet another aspect, membrane filtration is applied to a bitumen product effluent stream from a solvent extraction with solids agglomeration process. In still another aspect, membrane filtration is applied to bitumen produced by SAGD.

    摘要： A system and method of recovering heat and water from a slurry, such as tailings from oil sands extraction, is provided. The method includes providing the tailings to a humidification vessel, adding a sufficiently dry gas directly to the slurry in the vessel to form warm, water-saturated gas, such that heat and water are recovered from the slurry, removing the warm, water-saturated gas from the humidification vessel, providing the warm, water-saturated gas to a direct contact condensation vessel, cooling the gas in the condensation vessel to condense the water from the gas, thereby extracting water from the warm, water-saturated gas and recycling the dry gas, and recovering the water from the condensation vessel. Water which is of high quality, suitable for steam generation is obtained by a method in accordance with the present invention.

    摘要： A method recovering heat and water from a warm slurry, such as warm tailings from a oil sands extraction mining operation, is provided. The method comprises providing the tailings to a vacuum vessel, removing, from the vacuum vessel, warm vapor derived from the tailings, condensing the warm vapor in a condenser to produce water, and recovering the water from the condenser. Cool river or pond water can be warmed with the heat from the vapor for additional uses in the mining operation. Essentially pure water can be obtained in the process. This can also be achieved using one or flash vessels in series to condense the vapor. Power can also be generated from the vapor using a turbine.

    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： 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.
