Abstract: Rotating elements receivable within an extractor trough of an extractor configured for non-aqueous extraction of bitumen from oil sands are described. The rotating element can include a shaft operatively couplable to a motor, and projections extending outwardly from the shaft and being removably secured thereto. The rotating element can also include a shaft mounting structure couplable to a shaft, comprising a shaft receiving hub configured for receiving the shaft therein. The rotation of the rotating element can provide digestion and extraction of bitumen from the oil sands while advancing solids in a downstream direction within the extractor trough, as solvent diluted bitumen flows in an upstream direction toward a liquid outlet. Methods for servicing a rotating element and for manufacturing a non-aqueous extraction (NAE) extractor are also provided.

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: 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: 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: 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: 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: Provided herein are compounds of general Formula I: or agriculturally acceptable salts thereof. The compounds of Formula I can be used to improve the health of plants. For example, the compounds of Formula I can be used to inhibit a microbial pathogen of a plant, or to increase resistance of a plant to one or more abiotic stress. Methods of manufacturing the compounds of general Formula I, as well as synthetic intermediates are also provided.

Abstract: A method for increasing resistance of a plant to one or more abiotic stress is provided. The method includes applying to the plant a combination including: a macrocyclic tetrapyrrole compound selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof; and an oil selected from the group consisting of a mineral oil, a vegetable oil and a mixture thereof. Another method for increasing resistance of a plant to one or more abiotic stress is provided. The method includes applying a macrocyclic tetrapyrrole compound selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof, to at least one of a seed and a seedling of the plant. Corresponding compositions are also provided.

Abstract: A process for in situ thermal recovery of hydrocarbons from a reservoir is provided. The process includes: providing an oxygen-enriched mixture, fuel, feedwater and an additive including at least one of ammonia, urea and a volatile amine to a Direct-Contact Steam Generator (DCSG); operating the DCSG, including contacting the feedwater and the additive with hot combustion gas to obtain a steam-based mixture including steam, CO2 and the additive; injecting the steam-based mixture or a stream derived from the steam-based mixture into the reservoir to mobilize the hydrocarbons therein; and producing a produced fluid including the hydrocarbons.
