摘要： Described is a method of processing a bituminous feed. The bituminous feed is solvent extracted to form a bitumen-rich stream and a bitumen-lean stream. Solvent is recovered from the bitumen-rich stream to form a bitumen product. Solvent and water are recovered from the bitumen-lean stream to form dry tailings with a moisture content of less than 40 wt.%. The dry tailings are separated into at least two streams, each stream having a moisture content of less than 40 wt. %, based on at least one physical or chemical property. At least one of the at least two streams is then used at an oil sands mine site. In this way, the dry tailings may be used more effectively.

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： Processes are described for extracting hydrocarbon from a mineable deposit, such as bitumen from oil sands. The integration of solvent-based extraction processes with aqueous extraction processes is described. In one embodiment, water is removed from an aqueous bituminous feed that is then directed into a solvent-based extraction process. In another embodiment, a stream produced through solvent extraction is directed into a water-based extraction process. In the solvent-based extraction processes, agglomeration of fines may be employed to simplify subsequent solid-liquid separation. The process permits recovery of hydrocarbon that has conventionally may have been too difficult to recover from oil sands processing, and thus has previously been lost. Advantageously, a fungible product can be formed more efficiently according to certain integrated processes described herein.
摘要翻译：描述了从可开采沉积物中提取碳氢化合物的方法，如来自油砂的沥青。描述了溶剂型萃取方法与含水萃取方法的结合。在一个实施方案中，从含水沥青进料中除去水，然后将其导入基于溶剂的萃取方法中。在另一个实施方案中，将通过溶剂萃取产生的流引导到水基萃取过程中。在基于溶剂的萃取方法中，可以使用细粒团聚以简化随后的固液分离。该方法允许回收常规可能难以从油砂处理中回收的烃，因此先前已经丢失。有利地，可以根据本文所述的某些综合方法更有效地形成可替代的产品。

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： Systems, compositions, and methods for dewatering and/or increasing a mechanical strength of mine tailings. These systems, compositions, and methods may include combining mine tailings with wicking fibers to form a composite mine tailings mixture. The wicking fibers may provide a conduit for the removal of fluid from the composite mine tailings mixture. The composite mine tailings mixture further may include a binder that may decrease repulsive forces among fine particles that comprise the mine tailings and/or increase attractive forces among the fine particles, leading to a separation of the fine particles from at least a portion of the fluid contained within the composite mine tailings mixture. The composite mine tailings mixture may be placed in a storage or dewatering area as a composite mine tailings mixture deposit, which may include internal structure, such as layers of the composite mine tailings mixture and/or long-range orientation of the wicking fibers contained therein.
