Abstract:
Methods, systems and compositions used for recycling asphalt shingles are described herein. The methods and systems generally include combining asphalt shingles with a composition comprising an alkane solvent, an aromatic petroleum distillate, and N, N-Dimethyl 9-Decenamide. This composition accelerates the liquefaction of the asphalt component from the asphalt shingle and converts the asphalt to a usable oil product. Fiberglass and rock components of the shingles can be subjected to washing in order to collect residual oil, which may be combined with the oil obtained from liquefying and converting the asphalt component of the shingles to a usable oil.
Abstract:
A method of extracting bitumen from oil sands haung a transition temperature at which the oil sands solidif\ includes forming formable oil sands into pellets and cooling at least a surface of the pellets sufficienth to pre\ ent the pellets from aggregating, cooling the pellets to below the transition temperature, fracturing the pellets to release the bitumen from the oil sands while maintaining the temperature of the pellets below the transition temperature, and separating the bitumen from the oil sands in a separator.

In a first embodiment, the apparatus provides for improved separation of drilling fluid from drill cuttings on a shaker, the shaker including a shaker screen, an air vacuum system and a drilling fluid collection system. In a second embodiment, the shaker includes a shaker screen and an air blowing system.
Abstract:
There is provided a portable oil isolation and decontamination system comprising a plurality of high heat energy generators that supply high heat energy to an oil isolation and decontamination unit. Each heat energy generator comprises a chamber for gasifying used rubber tires, waste oil, coal or other combustible materials for the production of volatile gases and high energy heat. The oil extractor unit comprises a pair of parallel, elongate rotating cylinders that each rotate within a common closed housing. Oil-rich material such as oilsands, oilshale, contaminated soil or used oil is introduced into one end of each rotating cylinder and is caused to migrate to the opposite end in cascading fashion as the cylinder rotates. High energy heat from the generators is directed at the rotating cylinders to indirectly heat the oil-rich material therein to vaporize the hydrocarbons as the rotating drum migrates the oil-rich material towards its collection end. Vacuum pressure withdraws the vaporized hydrocarbons from the cylinder, and the cleaned sand or other solid material exits the collection end of each rotating cylinder and housing. The vaporized hydrocarbons condense and are collected within a forced-air condenser for recycling. An optional second stage refrigeration unit condenses any residual vaporized hydrocarbons that may be missed by the forced-air condenser.
Abstract:
The invention relates to material recycling, in particular to recycling and reusing roofing bituminous wastes. The inventive method consists in grinding wastes and in loading said wastes in a tank for melting bitumen and removing a paperboard base therefrom in the presence of a liquid contact heat carrier. During heating, a combustion gas is removed under a pressure from the furnace of the tank through a duct in order to reduce the combustion gas pressure and through a pipeline to a gas separator for retaining and deposing carbon. Afterwards, the gas is led to a filtering unit and exhausted to the atmosphere in the form of a pure air. The molten bitumen and a paperboard paste are removed from the melting tank and cooled to a temperature equal to or less than 140 DEG C. The paperboard paste is washed in a bitumen-solving reagent and is used for producing roofing materials and/or as a burning material. A liquid phase remaining after washing is used in the form of a base for producing bituminous paints, the carbon is used at least for producing mechanical rubber goods or as a dyestuff or as a pigment for a paint and varnish production. The device for carrying out said method and the elements thereof such as a gas separator, a gas filtering unit and a bitumen-melting boiler are also disclosed. Said invention makes it possible to optimise a process for a nonwaste and ecologically clean recycling of the roofing bituminous wastes, to increase the low-energy and low material consuming high performance production, reduce the reprocessing time, simplifies the method and reduce the material consumption of the device.
Abstract:
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.
Abstract:
It is described a separator (1) for separating at least two liquids having different density, the separator (1) comprising: - an inlet (3) having a first cross sectional area; - a flow channel (4) in fluid communication with the inlet (3), the flow channel (4) having a second cross sectional area being larger than the first cross sectional area; - a separation chamber (5) in fluid communication with the flow channel (4), the separation chamber (5) having a third cross sectional area being larger than the second cross sectional area; - a first outlet (6) in fluid communication with the separation chamber (5) for drainage of the liquid having the lower density; and - a second outlet (7) in fluid communication with the separation chamber (5) for drainage of the liquid having the highest density, wherein the separator (1) further comprises a first weir (62) for overflow of the lower density liquid and a second weir (712) for overflow of the highest density fluid, the first weir (62) having a higher elevation relative to the second weir (712).
Abstract:
A method for treating mature fines tailings (MFT) in a tailings pond, comprising injecting a fluid directly into the MFT layer, the fluid comprising an additive for further consolidating the MFT layer. The method may optionally include injecting a gas into the MFT layer to mix the fluid and the MFT and to float oil from the MFT layer for extraction.
