| 208424000 | Specified procedure to improve separation of solids from liquid product | 12 |
| 20100230325 | PROCESS FOR REMOVING OIL FROM PARTICULATE MATTER - There is provided a process for removing oil from particulate matter comprising mixing an aqueous slurry of the particulate matter with at least one stream of water applied at a pressure of from 0.5 to 100 Mpa, wherein the one or more high pressure water streams expand adiabatically when mixed with the aqueous slurry. | 09-16-2010 |
| 20110226673 | Oil Isolation and Decontamination Apparatus - 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. | 09-22-2011 |
| 20110278202 | APPARATUS AND METHOD FOR RECOVERING A HYDROCARBON DILUENT FROM TAILINGS - An apparatus and a method for separating diluted tailings containing a hydrocarbon diluent into a recovered diluent component and a diluent recovered tailings component. The method includes introducing the diluted tailings into a diluent recovery vessel so that they form a tailings pool in the diluent recovery vessel, introducing an amount of steam directly into the tailings pool, mixing the diluted tailings which are contained in the tailings pool, and maintaining the diluted tailings in the diluent recovery vessel for a residence time. The apparatus includes a diluent recovery vessel having a tailings pool section, a steam distributor located in the tailings pool section, and a mixing device associated with the tailings pool section. | 11-17-2011 |

| 208425000 | Including centrifugation, filtering, flotation or vibration | 8 |
| 20100012555 | METHOD FOR TREATING BITUMEN FROTH WITH HIGH BITUMEN RECOVERY AND DUAL QUALITY BITUMEN PRODUCTION - A process for removing contaminants, namely water and particulate solids, from hydrocarbon diluent-diluted bitumen froth (“dilfroth”) is provided to produce hydrocarbon diluent-diluted bitumen (“dilbit”), comprising subjecting the dilfroth to gravity settling in a primary settler to produce an overflow stream of primary raw dilbit, comprising bitumen containing water and some fine solids, and an underflow stream of primary tails, comprising solids, water and residual bitumen; removing the overflow stream of primary raw dilbit and subjecting it to gravity settling in a clarifier vessel for sufficient time to produce an overflow first stream of cleaned dilbit and an underflow stream of clarifier sludge; diluting the primary tails with hydrocarbon diluent and subjecting the diluted primary tails to gravity settling in a secondary settler to produce an overflow second stream of cleaned dilbit and an underflow stream of secondary tails; and removing the clarifier sludge and diluting the clarifier sludge with a hydrocarbon diluent, if necessary, and subjecting the clarifier sludge to gravity separation to produce a third stream of cleaned dilbit. | 01-21-2010 |
| 20100096298 | METHOD AND DEVICE FOR EXTRACTING LIQUIDS FROM A SOLID PARTICLE MATERIAL - A method, system, and device for separating oil from oil sands or oil shale is disclosed. The method includes heating the oil sands, spinning the heated oil sands, confining the sand particles mechanically, and recovering the oil substantially free of the sand. The method can be used without the addition of chemical extraction agents. The system includes a source of centrifugal force, a heat source, a separation device, and a recovery device. The separation device includes a method of confining the sands while allowing the oil to escape, such as through an aperture. | 04-22-2010 |
| 20100122939 | Solids Management in Slurry Hydroprocessing - The recovery of solids, and particularly solid particulates used as catalysts in slurry hydroprocessing, from asphaltene containing hydrocarbons is improved by controlling asphaltene precipitation. The formation of agglomerates of the solid particulates, having an increased diameter, results in the presence of precipitated asphaltenes, possibly due to flocculation. Asphaltene precipitation is controlled by varying process parameters or introducing additional diluent or flush streams that change the polarity of an asphaltene containing liquid product recovered from an effluent of a slurry hydroprocessing reaction zone. | 05-20-2010 |
| 20120193271 | MECHANICAL PYROLYSIS IN A SHEAR RETORT - Mechanical visbreaking and pyrolysis between counter-rotating coaxial centrifugal impellers in a continuous radial counterflow process minimizes wastewater discharges. In an embodiment, a cataclastic shear retort comminutes, shear thins, and shear heats an axial feed, such as tar sand, oil shale, coal tailings, distillation bottoms, or lignite. Pyrolyzing the feedstock in this shear retort yields a product stream of gases, naphthas, and oils which first mixes with the feedstock and then is axially extracted, while spent solids are simultaneously extruded from the periphery as coked devolatilized residue, such as char sand for upgrading soil to terra preta. Recirculation of shear-heated solids in long residence time within the shear retort brings heat from the spent solids at the periphery to the feedstock without an external heated sand loop.

| 20150027930 | COMPOSITE FEEDSTOCK FOR RECOVERY OF HYDROCARBONS FROM HYDROCARBONACEOUS MATERIAL - A method of reducing settling of residual comminuted hydrocarbonaceous material during processing can comprise forming a constructed permeability control infrastructure which defines a substantially encapsulated volume; introducing a composite comminuted hydrocarbonaceous material into the control infrastructure to form a permeable body, said composite hydrocarbonaceous material comprising a comminuted hydrocarbonaceous material and a structural material; and heating the permeable body sufficient to remove hydrocarbons therefrom such that the hydrocarbonaceous material is substantially stationary during heating, exclusive of subsidence and settling. The structural material can provide structural integrity to the permeable body sufficient to maintain convective flow of fluids throughout the permeable body during heating. | 01-29-2015 |
