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: Methods, processes and devices are described for measuring a volatile content of a process stream that comprises volatile species, such as light hydrocarbons and/or H2S. The method can include introducing a stripping gas into a sample of the process stream to strip the volatiles therefrom and produce a gas phase comprising vaporized volatiles; detecting the vaporized volatiles in the gas phase to obtain a sample volatile content; and determining the volatile content of the process stream based on the sample volatile content. The method and device can be used to measure a light hydrocarbon content of froth treatment tailings in the context of removing such light hydrocarbons prior to flocculating and dewatering the tailings.

Abstract: A system and method are provided for determining cleaning schedules for equipment. The equipment includes fired heaters and/or heat exchangers. The method includes obtaining historical sensor data; transforming the obtained sensor data using an engineering first principles process; applying data analytics to the transformed data to generate at least one statistical model; predicting an indicator of fouling in the equipment using operating data and the at least one statistical model; obtaining cost data associated with the equipment being analyzed; determining from the prediction and cost data a desired cleaning schedule for the equipment; and providing an output associated with the desired cleaning schedule.

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 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: Processes for upgrading a heavy oil or heavy oil-derived feedstock in presence of an ionic liquid are described, and can improve the heavy oil or heavy oil-derived properties such as viscosity and composition, and reduced contaminant content, such as a reduced Total Acid Number (TAN) and a reduced heavy metal content. Processes for upgrading heavy oil or heavy oil-derived in presence of an ionic liquid can include a catalytic cracking treatment carried out under catalytic cracking conditions, and/or a non-catalytic treatment, as well as various separation steps to separate the ionic liquid or a diluent if present in the feedstock. The ionic liquids that can be used in the context of the processes described herein include ionic liquids that are feed-miscible or feed-immiscible.

Abstract: A method and device for in-line injecting of flocculent agent into a fluid flow of mature fine tailings (MFT). The method includes the steps of: a) providing a fluid flow of mature fine tailings to be treated along a given channel fluidly connected to the pipeline; b) providing a source of flocculating agent; and c) introducing flocculating agent inside the fluid flow of mature fine tailings via a plurality of injection outlets for injecting the flocculating agent into the fluid flow in a dispersed manner so as to increase an exposed surface area of the injected flocculating agent and thus increase a corresponding reaction with the mature fine tailings, for an improved flocculation of said mature fine tailings, and/or other desired end results. Also disclosed is a kit with corresponding components for assembling the in-line injection device to be connected in-line with the pipeline carrying the mature fine tailings to be treated.

Abstract: Partial upgrading processes can include thermal treatment combined with solvent deasphalting, and recycling of certain streams, to process bitumen feedstocks and produce a bitumen product. The thermal treatment can be done so that the feedstock is in liquid phase at conditions below incipient coking conditions. Solvent deasphalting can be done before or after thermal treatment depending on the configuration of the process. Subjecting the bitumen feedstock to a partial upgrading can facilitate viscosity reduction of the bitumen feedstock and can facilitate avoiding the need for the addition of an external source of hydrogen.
