摘要： Described herein is a method of controlling bitumen quality in a process stream within a solvent-assisted bitumen extraction operation, for instance a hydrocarbon stream from a froth separation unit (FSU). Bitumen quality is a measure of the amount of selected contaminants in the process stream. Contaminants may include asphaltenes (comprising metal porphyrins), sulfur, and inorganic solids (comprising inorganic elements, e.g. Si, Al, Ti, Fe, Na, K, Mg, and Ca). First, the amounts of selected contaminants are measured. Next, these measured values are compared to maximum reference values. If one or more of these contaminants is higher than the maximum reference value, at least one variable of the solvent-assisted bitumen extraction is adjusted to improve bitumen quality.

摘要： A method and system for determining particle size distribution and/or filterable solids in bitumen-containing fluid is described. A sample of bitumen-containing fluid, such as bitumen-froth feed, bitumen-froth solvent or paraffinic-froth-treated (PFT) bitumen-solvent is obtained. An optimized diluent combination is determined, comprising an aromatic or cycloaliphatic solvent such as toluene, benzene, naphthalene, xylene, anthracene, or cyclohexane together with a C3 to C12 paraffinic solvent. The combination is considered optimized when diluting the sample with the combination maintains substantially the same level of deasphalting in the diluted sample as in the undiluted sample. Upon dilution of the sample with optimized diluent combination, particle size distribution can be accurately determined using optical instrumentation, laser diffraction instrumentation, electrical counting instrumentation, or ultrasonic instrumentation.

摘要： Systems and methods for dewatering mine tailings. The systems and methods include distributing a slurry of high permeability material on a sloped surface to define a high permeability layer and subsequently distributing a slurry of low permeability mine tailings on the high permeability layer to define a low permeability layer that is vertically above and in contact with the high permeability layer. The sloped surface defines a non-zero surface grade, and natural slopes of both the slurry of high permeability material and the slurry of low permeability mine tailings are within a threshold grade difference of the surface grade. In some embodiments, the systems and methods may include augmenting the slurry of high permeability material and/or augmenting the slurry of low permeability mine tailings to adjust the natural slope thereof.

摘要： A feedwell system for delivering a slurry (for example a bituminous slurry) to a separation vessel (for example a primary separation vessel) includes a feedwell barrel with an inlet for receiving the slurry, internal baffles, and a bottom outlet. A downpipe extends from the bottom of the barrel directing the existing slurry onto a deflector plate deflecting the slurry radially and outwardly. A protector plate located between the downpipe and the deflector plate improves the underwash layer stability. Ventilation openings in the protector plate induce inflow which reduces the discharge velocity, limits the formation of an adverse pressure gradient and encourages circumferential distribution.
