Abstract: An integrated process that is operated to create both a higher value pipelineable crude and a higher value carbon fiber product from a lower value common heavy hydrocarbon feedstock where the feedstock is processed in a thermal reactor followed by a solvent deasphalting unit with the liquids being gathered and processed to reduce olefins for pipeline transport and the solids are processed to generate a marketable carbon fiber product with any gases generated throughout the entire process reused in the process or sold.

Abstract: A non-aqueous process for producing bitumen from oil sands is provided, and includes contacting oil sands and solvent to produce solvent diluted bitumen and solvent diluted tailings. The solvent diluted bitumen is subjected to a first fines separation stage that produces an overflow solvent diluted bitumen stream with residual fines that is subjected to a second fines separation stage to remove residual fines and produce a solvent diluted bitumen stream, which is subjected to solvent recovery. The fines streams are subjected to washing to produce washed tailings and solvent wash liquor comprising solvent and bitumen. Another non-aqueous process for producing bitumen from oil sands is provided, and includes subjecting oil sands to solvent extraction, including displacing the oil sands material and a solbit counter-currently and horizontally, and recovering a bitumen enriched solbit stream which is subjected to fines separation and subjecting the solvent diluted bitumen stream to solvent recovery.

Abstract: A non-aqueous extraction process for producing a bitumen product from an oil sands material that includes an ablation stage is provided. The ablation stage can include adding an ablation solvent to an oil sands material to achieve a solvent-to-ore ratio of less than about 10, mixing the ablation solvent and the oil sands material to reduce the size of the oil sands material and produce ablated ore that includes ablated ore fragments having a diameter of less than about 2 inches, and retrieving the ablated ore as a single stream. The ablated ore can be subjected to a reject separation stage to separate reject material therefrom. The reject material can also be subjected to a wash reject stage. The ablated ore can then be subjected to an extraction stage. Examples of ablators are also described, which can include for instance a conveyor, or can be a rotary screen ablator.

Abstract: A non-aqueous extraction (NAE) process for producing bitumen from oil sands ore can include a multistage bitumen extraction step where paraffinic solvent and deasphalted oil are added at a downstream stage of extraction at solvent-to-bitumen ratios below asphaltene precipitation onset threshold to remove bitumen from the solid mineral material, while the ore is added to a first stage to mix with the solvent-bitumen mixture and produce solvent diluted bitumen. The process includes recovering the solvent diluted bitumen and the solvent diluted tailings from the extraction step. The solvent diluted bitumen is subjected to deasphalting to produce solvent diluted deasphalted bitumen that is used as a source of the paraffinic solvent and deasphalted oil supplied to extraction. The tailings and asphaltene fraction from deasphalting can be subjected to washing and the washed material can then be subjected to sand solvent recovery. The NAE process can be operated within an operating envelop for effective and efficient performance.

Abstract: There is provided a process and system for producing carbon fiber products. The process can involve deasphalting a heavy hydrocarbon feedstock, which can contain native asphaltenes, to produce a solid asphaltene particulate material, which can be further treated to produce the carbon fiber products. In some implementations, the solid asphaltene particulate material can be extruded in the presence of a polymer. In some implementations, the solid asphaltene particulate material can be chemically treated with a chemical agent including a Lewis acid, an oxidizing agent and/or a reducing agent before extrusion. In some implementations, the process can further produce activated carbon fibers.

Abstract: A process that catalytically converts olefinic (Alkenes, typically liquid at standard temperature and pressure) material in thermally cracked streams to meet olefin content specifications for crude oil transport pipelines. A thermally cracked stream or portion of a thermally cracked stream is selectively reacted to reduce the olefin content within a reactor operating at specific, controlled conditions in the presence of a catalyst and the absence of supplemental hydrogen. The process catalyst is comprised of a blend of select catalyzing metals supported on an alumina, silica or shape selective zeolite substrate together with appropriate pore acidic components.

Abstract: A tube and tubesheet assembly is provided, which includes a tubesheet, the tubesheet comprising at least one tube insertion aperture therethrough; at least one tube inserted in the at least one tube insertion aperture; and a damage-resistant layer applied to an edge of the at least one tube and along an inner surface of a portion of the tube that is positioned within the corresponding tube insertion aperture. A heat exchanger including the assembly is also provided. A method is also provided for coupling a tube to a tubesheet. The method includes applying a damage-resistant layer to an edge of the tube and along an inner surface of a portion of the tube that is positioned within a tube insertion aperture in the tubesheet. The method can also be used to repair tubes and retrofit pre-existing tube-to-tubesheet joints.

Abstract: Various techniques are provided in relation to flocculation and/or dewatering of thick fine tailings, with shear conditioning of flocculated tailings material in accordance with a pre-determined shearing parameter, such as the Camp Number. One example method of treating thick fine tailings including dispersing a flocculant into the thick fine tailings to form a flocculating mixture; shearing the flocculating mixture to increase yield stress and produce a flocculated mixture; shear conditioning the flocculated mixture to decrease the yield stress and break down flocs, the shear conditioning being performed in accordance with the pre-determined shearing parameter to produce conditioned flocculated material within a water release zone where release water separates from the conditioned flocculated material. The conditioned flocculated material can then be subjected to dewatering, for example by depositing, thickening or filtering. The design, construction and/or operation of a flocculation pipeline assembly can be facilitated.
