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 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.

Abstract: Implementations of the present disclosure relate to a method of operating a coker unit comprising the steps of: collecting a coker-furnace feed stream; introducing the coker-furnace feed-stream into a coker furnace for producing a coker-drum feed stream; and introducing a hydrogen-donor gas into either or both of the coker-furnace feed stream or the coker-drum feed stream.

Abstract: Provided herein is a liner that can be loosely inserted in process pipe to form a lined pipe and to decrease the rate of heat transfer between process fluids flowing through the liner and the process pipe. The liner provided herein can reduce applied thermal loading on the outer pipe resulting from, for example, turbulent mixing between fluids having different temperatures (with or without stratification), circumferential thermal gradients, and/or longitudinal thermal gradients. An annulus between the process pipe and liner can be at least partially filled by process fluids, thereby creating a thermal buffer to further decrease the rate of heat transfer between the fluids and the process pipe.

Abstract: A method and device for in-line injecting of flocculated 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: 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.
