| 161 | Method and apparatus for creating a slurry | US11558303 | 2006-11-09 | US07651042B2 | 2010-01-26 | Bradford E. Bjornson; Garth Robert Booker |
| A mobile slurry apparatus for creating a slurry from oil sand ore has a frame and a slurry box supported by the frame. Water is mixed with the ore to form a slurry that is retained in the slurry box. The frame base has a first set of spaced apart support points for supporting the frame in a stationary mode, and a second set of spaced apart support points for supporting the frame in a moving mode. The second set of spaced apart support points is closer together than the first set of support points and defines a lifting region disposed beneath a center of gravity of the slurry apparatus in a moving mode when the slurry box is empty. Thus, a single moving device can be positioned beneath the second set of support points for lifting and moving the slurry apparatus. | ||||||

| A separating apparatus can be used for separating components of a fluid. The apparatus can include a substantially open cylindrical vessel and a helical confined conduit connected upstream of the cylindrical vessel. The open vessel can include an open vessel inlet configured to introduce a fluid tangentially into the open vessel. The helical confined conduit can be connected to the open vessel at the open vessel inlet. A series of gas nozzles can be used to introduce gas bubbles into the helical confined path and/or the open vessel which draw bitumen from an outer flow region to an inner flow region of the slurry. An overflow outlet and underflow outlet can be operatively attached to the open vessel for removal of the separated fluid components. Although a number of fluids can be effectively treated, de-sanding of bitumen slurries from oil sands can be readily achieved. | ||||||
| 163 | METHOD AND APPARATUS FOR PROCESSING A SIZED ORE FEED | US12242642 | 2008-09-30 | US20090133987A1 | 2009-05-28 | Terry Dirk; Paul Frederick MacDougall |
| A method and process line apparatus for processing a sized ore feed excavated from an ore deposit is disclosed. The method involves disposing a processing apparatus in a processing apparatus position relative to the ore deposit, and disposing a first mobile conveyor to receive a sized ore feed at a receiving location located along a length of the first mobile conveyor. The first mobile conveyor is operable to convey the sized ore from the receiving location to a discharge end of the first mobile conveyor. The method also involves disposing a second mobile conveyor to receive the sized ore from the discharge end of the first mobile conveyor at a transfer location along a length of the second mobile conveyor and to convey the sized ore from the transfer location to the processing apparatus. The first and second mobile conveyors are oriented at an operational angle between a length of the first mobile conveyor and a length of the second mobile conveyor. The method further involves moving at least one of the first and second mobile conveyors to vary at least one of the operational angle and the transfer location to permit successive portions of the ore deposit within operational reach of the receiving location to be received for conveying along the first and second mobile conveyors to the processing apparatus while the processing apparatus is located in the processing apparatus position. | ||||||

| A mixer especially suited for treating a mixture of mineral substrate particles and hydrocarbon compounds, especially tar sands and contaminated soils, to recover a hydrocarbon portion and a cleaned substrate portion. Hydrocarbonaceous rock, sand, ore, or soil containing bitumen, petroleum, and/or kerogen is crushed or otherwise comminuted as needed to the particle size of sand or smaller. The comminuted ore is mixed with water to form a slurry, is heated to between 60° C. and 100° C., and is agitated with an oxidant in aqueous solution, preferably hydrogen peroxide, in a flow-through mixer having a low axial flow rate and a high radial flow rate. Both free interstitial hydrocarbons and those hydrocarbons bound electrostatically to the surfaces of clay-like particles in the ore are released from the mineral substrate. Some of the released hydrocarbon compounds may be controllably cleaved by the oxidant to yield organic compounds having lower average molecular weights which are suitable for refining as oil after separation from the process water phase and the residual particulate mineral substrate. The water and mineral tailings from the process are substantially free of hydrocarbon contamination and are environmentally suitable for landfill disposal. | ||||||

| Discloses a mined ore processing apparatus to process mined ores, such as oil sands ore, into granular material. An ore processor bed receives the ore to be processed. The ore processor bed has a frame supporting several rotating elements each separately driven to provide independent rotation rate and direction from the other. The ore processing bed is operable as a sizing device to decimate mined ore supply into granular material and separating it from rocks and other large lump mineral materials found in situ. The ore processing bed may be oriented to provide an upward inclination, which, when combined with alternating rotating element rotation directions, provides a crushing action to the ore material to crush larger rock. Alternately, a rock crusher is also provided to disintegrate oversized materials. | ||||||
| 168 | Method and apparatus for using peroxide and alkali to recover bitumen from tar sands | US10865641 | 2004-06-10 | US20040222164A1 | 2004-11-11 | Lawrence Conaway; Michael R. Keller; Roger K. Noble |
| Method and apparatus for treating an ore comprising mineral substrate particles surrounded by hydrocarbon compounds, especially tar sand grains, process tailings, and contaminated soils, to recover a hydrocarbon portion and a cleaned substrate portion. In a preferably continuous process, hydrocarbonaceous rock, sand, ore, tailings, or soil containing bitumen, petroleum, and/or kerogen may be crushed or otherwise comminuted as needed to provide a particle size of sand or smaller. The ore is mixed with water to form a slurry, which may also contain alkali, for example, sodium hydroxide or sodium bicarbonate. The slurry is heated to about 80null C. and is intensively sheared to condition the slurry for separation, preferably by shear-fracture of the hydrocarbon layers surrounding the particles in the grains. The conditioned slurry is blended with a peroxide in aqueous solution, preferably hydrogen peroxide, which enters the grains and is decomposed therein, creating bubbles of free oxygen within the grains which disrupt the hydrocarbon envelope. In decomposing, the peroxide increases the hydrophilicity of the particle surfaces. Both free and bound hydrocarbons in the ore are thereby released from the mineral substrate particles. The resulting hydrocarbon globules are separated from the substrate particles by flotation, accelerated by attached oxygen bubbles. Alkali and/or peroxide may be added during the flotation process. Water and mineral tailings from the process are substantially free of hydrocarbon contamination and are environmentally suitable for landfill disposal. | ||||||
| 169 | Methods and apparatus for recycling asphalt shingle material | US09838045 | 2001-04-18 | US20020066813A1 | 2002-06-06 | Donald J. Mischo |
| Initial processing of used and manufacturing scrap asphalt shingle material includes (i) shredding the shingle material into pieces of a predetermined maximum size, (ii) separating the shredded material into (a) fine material and (b) course material, and (iii) forwarding the fine and course material to different finishing processes. The fine material comprises the smaller sized pieces of shredded shingle material and loose aggregate dislodged from the larger sized pieces during the shredding process. The course material comprises the larger flakes from the shredding process. The fine material is forwarded for finish processing such as into shaped products adapted to take advantage of the high aggregate content therein. The flakes are forward to finish processing such as into ground cover and/or erosion control products to take advantage of the larger size and low aggregate content. | ||||||

| A method for treating hydrocarbonaceous deposits to recover a petroleum-like hydrocarbon portion and a cleaned particulate substrate portion. Hydrocarbonaceous ore containing bitumen and/or kerogen is crushed or otherwise comminuted to the particle size of sand or smaller. The comminuted ore is mixed with water to form a slurry, is heated to between 60null C. and 100null C., and is blended with an oxidant in aqueous solution, preferably hydrogen peroxide. Both free interstitial hydrocarbons and those hydrocarbons bound electrostatically to the surfaces of clay-like particles in the ore are released from the rock substrate in a putative electrophysical reaction in the presence of the oxidant. Some of the released bituminous and kerogenic compounds are then controllably cleaved by the oxidant in a limited Fenton's reaction to yield organic compounds having lower average molecular weights which are suitable for refining as oil after separation from the process water phase and the residual rock substrate. The water and rock tailings from the process are substantially free of hydrocarbon contamination and are environmentally suitable for landfill disposal. | ||||||
| 172 | Method for extracting bitumen from tar sands | US647850 | 1996-05-15 | US6110359A | 2000-08-29 | R. Michael Davis; James M. Paul |
| A method for extracting bitumen from crushed mined tar sands comprising contacting the mined tar sands with a solvent in the presence of sonic energy in the frequency range of 0.5 to 2.0 kHz. Specifically, a solvent is first mixed with crushed mined tar sands and the mixture is then formed into a slurry of tar sand suspended in the solvent. Thereafter the tar sand slurry is injected into the top of a vertically disposed, substantially rectangular shaped, hollow acoustic chamber of uniform cross-section. Fresh solvent is injected into the bottom of the acoustic chamber and flows upwardly through the cell. The fresh solvent is injected into the bottom of the acoustic chamber at a rate low enough whereby the tar sand particles in the slurry fall by gravity through the upwardly flowing solvent. The tar sand particles and solvent in the acoustic chamber are subjected to acoustic energy in the frequency range of 0.5 to 2.0 kHz whereby the bitumen is separated from the tar sand and dissolved by the upwardly flowing solvent without cavitation of the solvent. The bitumen dissolved in the solvent is recovered from the top of the acoustic chamber and transferred by pipeline to an off-site refinery. The bitumen-extracted sand particles recovered from the bottom of the acoustic chamber may be recycled to the top of the acoustic chamber to recover additional bitumen after injection of the slurry has been discontinued. | ||||||
| 173 | Tar sands extraction process | US56694 | 1998-04-08 | US5985138A | 1999-11-16 | Reginald D. Humphreys |
| A hot water extraction process for extracting bitumen from tar sands is taught wherein the tar sand is conditioned using an alkali metal bicarbonate, an alkali metal carbonate and a liquid hydrocarbon. A source of calcium and/or magnesium ions can also be added. The conditioning step replaces the step of conditioning using caustic soda previously used in tar sand extraction. The use of the alkali metal bicarbonate and carbonate and a liquid hydrocarbon substantially eliminates the production of sludge in tar sand extraction and maintains or improves bitumen recovery. The process allows for hot conditioning solution to be recycled to the process by use of a recycle storage tank. | ||||||
| 174 | Treatment of oil-contaminated particulate materials | US864184 | 1997-05-28 | US5882524A | 1999-03-16 | Dale Storey; Kevin Lundie |
| A closed loop process is shown for treating oil and saline contaminated particulate materials such as drilling cuttings such as are encountered in oil and gas well bore drilling operations. The process includes at least two washing stages and three solids separation stages. A process fluid tank utilizes an auger to remove deposited solids from the process fluid while hot gases being bubbled through the tank facilitate separation and skimming of oil and hydrocarbon components from the tank surface. | ||||||
| 175 | Method of treating organic contaminated materials | US807643 | 1997-02-27 | US5797701A | 1998-08-25 | Lawrence M. Conaway |
| Friable solid material contaminated by oxidizable hydrocarbons such as petrochemicals is delivered into a system wherein that material is subjected to a series of physical and chemical reactions to separate the contaminants from the solid material. The system can receive solid material, separate coarse and fine material and suspend the fine material in an aqueous medium. The aqueous suspension is subjected to temperature adjustment and the addition of an oxidizing agent preferably hydrogen peroxide. The suspension is agitated for a period of time to allow the hydrocarbons to be oxidized. The gaseous oxidation products are stripped and separated from the residual solid material. The aqueous suspension of solid material and diluent are physically separated and the solid material may be returned to its point of origin after treatment. The process and apparatus for carrying out the process are preferably applied to soils containing hydrocarbon pollutants. | ||||||
| 176 | Process for reducing sludge accumulation in the hot water extraction process for oil sands | US319000 | 1994-10-06 | US5492628A | 1996-02-20 | Robert Schutte |
| A dispersant, such as sodium silicate, is added to the process water of the hot water extraction process which recovers bitumen from oil sands. The dispersant disperses the ultrafine (less than 300 nm) particles, to reduce the formation of flocs and sludge in the tailings pond. The volume of the pond is such that the retention time of process water is sufficiently short (less than 6 weeks when using sodium silicate) to avoid reforming flocs from the dispersed ultrafines. The ultrafines content in the process water builds up as the water is repeatedly recycled from the pond to the extraction process. The ultrafines content stabilizes at a steady state concentration as some ultrafines are continuously removed from the process water when the tailings are delivered onto the "beach" of the pond and become trapped in the sand. | ||||||
| 177 | Method for releasing and separating oil from oil sands | US66044 | 1993-11-22 | US5480566A | 1996-01-02 | William L. Strand |
| An oil sands separator includes a drum (10) having a solids discharge end (24) and a liquid discharge end (22) and a spiral ribbon (14) having a plurality of flights wound inside the interior of the drum. A first plate (28) partially closes the solids discharge end and has a first opening (32) disposed within it. A second plate (26) partially closes the liquid discharge end and has a second opening (30) disposed within it. A conveyor (46) is provided at the liquid discharge end for conveying feed into the drum through the second opening and into the spiral ribbon. A pipe (50) at the solids discharge end conveys hot water into the drum through the first opening. Pockets (40) at the solids discharge end remove solids from the drum as a drive rotates the drum and its spiral ribbon. A process of releasing and separating oil from oil sand involves the steps of conveying oil sand to a feed end of a hot water bath, providing hot water to a solids discharge end, opposed to the feed end, of the separator in an amount sufficient to cover the oil sand in the separator, flowing the hot water to the feed end of the separator, moving the oil sand to the solids discharge end of the separator while gently rolling the oil sand in the hot water to release oil from the sand and allow it to separate into the hot water, removing solids from the solids discharge end of the separator; and removing the hot water and oil from the feed end of the separator. | ||||||

| A system for removing oil from oil/water or oil/sand or oil/water/sand mixtures. An oil/water mixture is taken from an oil spill on the surface of the water or from other sources such as producing oil wells and is transported to a surge tank where it is agitated and then passed on to a separator which separates the oil from the water. The system also covers separating oil from sand or earth when the spill is on land. | ||||||
| 180 | Process for treating wastes from the machining of ferromagnetic materials | US720379 | 1991-06-25 | US5147554A | 1992-09-15 | Alfred Heck |
| A process and apparatus for treating waste which contains ferromagnetic components, such as the grinding sludge from grinding ferromagnetic materials which contains ferromagnetic particles contaminated with water and oil, in which the waste is introduced into a separating tank containing a washing solution and mixed with the solution by stirring until the oil dissolves. Subsequently, a magnetic field is produced at the separating tank wall which causes magnetic components to accumulate on the wall. The wash solution is then filtered to remove non-ferromagnetic solids. The magnetic field is subsequently removed, and accumulated ferromagnetic components are released into the wash solution. The ferromagnetic components are then filtered out from the wash solution and dried, and the filtered wash solution is conveyed to an oil separation tank where oil separated from the waste is recovered. | ||||||
