摘要： Methods and systems for treating tailings at an elevated pH using lime are disclosed herein. In some embodiments, the method comprises (i) providing a tailings stream comprising bicarbonates and a pH less than 9.0, (ii) adding a coagulant comprising calcium hydroxide to the tailings stream to form a mixture having a pH of at least 11.5 and a soluble calcium level no more than 800 mg/L, and (iii) dewatering the mixture to produce a product having a solids content of at least 40% by weight. In some embodiments, the pH and soluble calcium level of the mixture cause chemical modification of clay materials of the mixture via pozzolanic reactions. In some embodiments, the undrained shear strength of the product increases over a period of time of at least two days.

摘要： A system and method for extracting liquid and solid hydrocarbons and their derivatives from natural and man-made hydrocarbon sources, including but not limited to oil sands, bitumen, asphalt, roofing shingles, and other hydrocarbon articles of manufacture. The hydrocarbon sources are prepared by dissolving, crushing and/or grinding. The prepared hydrocarbon sources are subjected to agitation where the solvent and hydrocarbon source as thoroughly mixed. The results of the agitation are then separated in one or both of a mesh screen shaker and a centrifuge. The mesh screen shaker subjects the materials to medium frequency oscillations. The centrifuge subjects the materials to high G-forces. The combined processes separate the hydrocarbons from solids and residual solids to less than 0.2% by weight.

摘要： The system and method for remediation of oil-contaminated sand provides for washing and separation of sand from oil and oil-based contamination. The system for remediation of oil-contaminated sand includes a soil washing system for receiving a volume of oil-contaminated sand. The soil washing system mixes the volume of oil-contaminated sand with water to produce a mixture. This mixture is then delivered to a sand separator for separation into a volume of treated sand and a volume of oily wastewater. A flocculation tank receives the volume of oily wastewater. In the flocculation tank, the oily wastewater is mixed with at least one coagulant to separate the oily wastewater into treated water and oily sludge. A sludge hopper receives the oily sludge for collection. A treated water tank receives the treated water for collection and storage.

摘要： A method of electro treating tailings in a containment structure to cause a separation of at least some water from said tailings and a consolidation and compaction of at least some solid particles is shown. The method includes placing a plurality of first electrodes in the tailings to be treated generally along one side of a predetermined volume and placing a plurality of second electrodes in the tailings to be treated generally along an opposite side of said volume to the plurality of first electrodes, said first and second electrodes being spaced apart by a predetermined distance. The next step is applying a treatment current across said distance between said spaced first and second electrodes to create an electrical field which causes solids to consolidate at one of said plurality of first and second electrodes; and creating a geotechnical structure within said volume comprised of dewatered solids consolidated from said tailings around one of said electrodes. The geotechnical structure may be a layer at the bottom of the containment structure, along a side of the containment structure or across the top of a containment structure.

摘要： Feeding a slurry comprising inert solids, liquid hydrocarbons, liquid water and sometimes dissolves solids to a unit having a casing defining a thermal extraction chamber heated both directly and indirectly in which first and second intermeshing screws rotate, the screws in close tolerance with each other and with inside casing surfaces. The casing and screws define a tortuous flow path in which the slurry and a vaporous composition evolved therefrom flow. The intermeshing screws push the slurry toward a discharge end of the chamber at a first velocity while reducing pressure and increasing temperature in the chamber, while rotating the screws to create turbulent vacuum thermal conditions in the chamber to physically transform some or all of the slurry into the vaporous composition. The vaporous composition traverses the tortuous flow path with a second velocity at least 1.5 times the first velocity, optionally forming a heated, substantially dry, composition comprising the inert solids.

摘要： 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.

摘要： A solvent diluted bitumen is produced by a method that includes adding paraffinic solvent to bitumen froth to form a solvent diluted bitumen froth, and discharging the solvent diluted bitumen froth into a vessel, such that settlement of the solvent diluted bitumen froth in the interior of the vessel establishes a heavier phase zone, a lighter phase zone, and an interface. A discharge point is located above the interface and within the lighter phase zone. Lighter phases separate up toward an overflow outlet of the vessel while heavier phases separate down toward an underflow outlet of the vessel. The solvent diluted bitumen is collected from the overflow outlet, and a solvent diluted underflow stream is collected from the underflow outlet.

摘要： Disclosed are processes for producing crude oil and bitumen products of relatively high quality from oil sand. The processes for producing the high quality crude oil and bitumen products involve a Phase I and/or Phase II extraction solvent. According to the Phase I process, a high quality bitumen-derived crude oil can be produced using a Phase I type solvent. According to the Phase II process, a substantial amount of the bitumen on the oil sand can be extracted using a Phase II type solvent, while producing a relatively dry tailings by-product. The Phase I and Phase II extraction processes can be carried out independently or in conjunction with one another.
