Monitoring of residual metals in paraffinic froth treatment operations and process control
Techniques provided herein relate to regulating at least one operating parameter of a paraffinic froth treatment (PFT) operation and controlling the quality of the produced bitumen in response to a determined concentration of at least one residual metal in a PFT process stream. Determination of the residual metal concentration is based on acquired NIR spectral measurements of the PFT process stream. An alkaline agent dosage in primary extraction operation can be for example regulated in response to a difference between a determined calcium concentration and a calcium concentration specification.
METHODS FOR PRODUCING ADVANCED CARBON MATERIALS FROM COAL
A method of producing advanced carbon materials can include providing coal to a processing facility, beneficiating the coal to remove impurities from the coal, processing the beneficiated coal to produce a pitch, and treating the pitch to produce an advanced carbon material such as carbon fibers, carbon nanotubes, graphene, resins, polymers, biomaterials, or other carbon materials.

METHOD AND APPARATUS FOR USING VELOCITY PROFILE MEASUREMENTS IN RECOVERING BITUMEN FROM A COARSE TAILINGS LINE
The present invention provides techniques for recovering hydrocarbon fluids in a process flow, including recovering bitumen from a coarse tailings line. The apparatus includes a signal processor that responds to signaling containing information about the presence of a hydrocarbon fluid in a process flow; and determines corresponding signaling to control the diversion of the hydrocarbon fluid from the process flow remaining based on the signaling received. The hydrocarbon fluid may be bitumen, including bitumen flowing in a course tailings line. The signal processor receives the signaling from a velocity profile meter having sensors arranged around a circumference of a process pipe containing information about a fluid flow velocity at various levels or heights within the process pipe, including a wrap-around velocity profile meter having multiple sensing arrays located radially at a top position of 0°, a bottom position of 180°, and intermediate positions 45°, 90° and 135°.
RECOVERY OF HYDROCARBON DILUENT FROM FROTH TREATMENT TAILINGS
A method for recovering hydrocarbon diluent present in froth treatment tailings, comprising introducing the tailings into a vessel; adding a first portion of steam into the vessel to form a vapour-tailings interface; and operating the vessel to increase the exposure of the tailings to the vapour-tailings interface formed in the vessel.
Method of producing liquid fuel from carbonaceous feedstock through gasification and recycling of downstream products
A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.
CHEMICAL REACTOR WITH HIGH SPEED ROTARY MIXING, FOR CATALYTIC THERMAL CONVERSION OF ORGANIC MATERIALS INTO DIESEL AND OTHER LIQUID FUELS, AND APPLICATIONS THEREOF
Chemical reactor with high speed rotary mixing, system thereof, and method thereof, for catalytic thermal conversion of organic (hydrocarbon-containing) materials (coal, plastics, rubber, plant matter, wood shavings, biomass, organic wastes) into diesel and other liquid fuels (automobile or/and jet engine fuels). Relevant to non-conventional commercial scale production of liquid fuels, and to commercial scale processing and disposing of organic waste materials. Chemical reactor includes: integrated combination of a reactor stationary assembly (RSA), having only stationary components remaining stationary during chemical reactor operation, and a reactor rotary mixing assembly (RRMA), having only rotatable components rotating during chemical reactor operation. May include anti-abrasion shield for shielding inner surface of reactor central housing from abrasion during chemical reactor operation. Rotor may include a reinforcement disc. Rotor blades or/and reinforcement disc may include rotor-based performance and process control structural features (openings, or/and protrusions, or/and depressions), for additionally controlling performance of the rotor.

CALCINED CLAY TAILINGS AND/OR CALCINED MINE WASTE, AND ASSOCIATED SYSTEMS AND METHODS
Methods and systems for calcining dewatered tailings and/or mine waste are disclosed herein. In some embodiments, the method comprises (i) processing dewatered tailings comprising clay minerals, (ii) calcining the processed tailings to produced calcined tailings, and (iii) altering a composition and/or one or more characteristics of the calcined tailings to produce a cementitious product. Altering the composition can include blending the calcined tailings with one or more additives, such as lime, dolomitic lime, lime kiln dust, argillaceous limestone, limestone, pulverized quicklime, ground calcium carbonate, quicklime, gypsum, natural pozzolans, artificial pozzolans, water, flow aids, or the like.
Process and process line for solvent extraction of bitumen from oil sands
A process for forming a deaerated oil sand slurry is provided comprising: providing a first vessel having an overhead space and a bottom space; delivering oil sand and a low vapor pressure hydrocarbon liquid into the overhead space and mixing the oil sand and hydrocarbon liquid to release air trapped in the oil sand and form the deaerated slurry; optionally adding an inert gas stream to the overhead space to displace the air released from the oil sand; and collecting the deaerated slurry in the bottom space to form a slurry layer to prevent gas exchange between the first vessel and downstream extraction equipment.
