Publication number: 20110192768Abstract: In a method for enhancing the efficiency of bitumen recovery from oil sands ore, CaO lime (or Ca(OH)2) is mixed into an oil sands ore-water slurry prior to or during the operation of slurry-based bitumen extraction processes. The lime is introduced at dosages effective to reduce the electro-chemical attraction between clay particles and bitumen in the slurry, thereby promoting detachment of clay particles from bitumen droplets in the ore-water slurry. This occurs because water-soluble asphaltic acids formed at the bitumen-water interface act as surfactants which reduce or eliminate the activity of Ca2+ and Mg2+ ions binding the clay particles and bitumen together. The detachment of clay particles promotes the attachment of air bubbles to the bitumen droplets, thereby forming a bitumen-rich froth which will float to the surface of the ore-water slurry, thus facilitating bitumen recovery.Type: ApplicationFiled: April 22, 2011Publication date: August 11, 2011Inventor: Baki OZUM

The amines or ammonia and amines may be injected downhole or admixed with heavy hydrocarbon containing ore on the surface, optionally with water or steam. Ammonia may be used alone with high quality steam.Type: GrantFiled: December 8, 2008Date of Patent: May 10, 2011Assignee: Baker Hughes IncorporatedInventors: Paul Robert Hart, Brian J. Stefan, Piyush Srivastava, Justin D. Debord

Patent number: 7931800Abstract: In a method for enhancing the efficiency of bitumen recovery from oil sands ore, CaO lime (or Ca(OH)2) is mixed into an oil sands ore-water slurry prior to or during the operation of slurry-based bitumen extraction processes. The lime is introduced at dosages effective to reduce the electro-chemical attraction between clay particles and bitumen in the slurry, thereby promoting detachment of clay particles from bitumen droplets in the ore-wafer slurry. This occurs because water-soluble asphaltic acids formed at the bitumen-water interface act as surfactants which reduce or eliminate the activity of Ca2+ and Mg2+ ions binding the clay particles and bitumen together. The detachment of clay particles promotes the attachment of air bubbles to the bitumen droplets, thereby forming a bitumen-rich froth which will float to the surface of the ore-water slurry, thus facilitating bitumen recovery.Type: GrantFiled: March 14, 2008Date of Patent: April 26, 2011Assignee: Apex Engineering Inc.Inventor: Baki Ozum

Patent number: 7913852Abstract: Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal ores), including the beneficiation of impure coal comprising clay impurities, as well as in the separation of valuable bitumen from solid contaminants such as sand. The modified resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water. The modified resins comprise a base resin that is modified with a coupling agent, which is highly selective for binding to solid contaminants and especially siliceous materials such as sand or clay.Type: GrantFiled: December 12, 2005Date of Patent: March 29, 2011Assignee: Georgia-Pacific Chemicals LLCInventors: James Wright, Carl R. White, Kurt Gabrielson, John B. Hines, Phillip W. Hurd, Lisa M. Arthur, Paul Hart, Richard Rediger, Robbie D. Kelly

Patent number: 7914670Abstract: An inline bitumen froth steam heater system including steam injection and static mixing devices is provided. The system heats and de-aerates input bitumen froth without creating downstream processing problems with the bitumen froth such as emulsification or live steam entrainment. The system is a multistage unit that injects and thoroughly mixes steam with bitumen resulting in output bitumen material having temperature of about 190° F. The system conditions a superheated steam supply to obtain saturated steam at about 300° F. The saturated steam is contacted with bitumen froth flow and mixed in a static mixer stage. The static mixers provide surface area and rotating action that allows the injected steam to condense and transfer its heat to the bitumen froth. The mixing action and increase in temperature of the bitumen froth results in reduction in bitumen viscosity and allows the release of entrapped air from the bitumen froth.Type: GrantFiled: June 29, 2009Date of Patent: March 29, 2011Assignee: Suncor Energy Inc.Inventors: Les Gaston, Donald Norman Madge, William Lester Strand, Ian Noble, William Nicholas Garner, Mike Lam

Publication number: 20110017643Abstract: Oil sands ore containing bitumen is treated in a reactor chamber by ultrasonic oscillations impact such that cavitation of ore molecules occurs. The disintegration of the pulsating bubbles in the cavitation results in the separation of the oil, water, sand and air fractions of the oil sands. The oil fraction may be continuously extracted for subsequent refining processes.Type: ApplicationFiled: July 27, 2009Publication date: January 27, 2011Inventors: Vadim Donchenko, Igor Myakotin, Sergey Rakhinskiy, Lazarus Saidakovsky

Publication number: 20100307959Abstract: A method for extracting hydrocarbons from sands can include: providing sands containing a hydrocarbon; mixing the hydrocarbon sands with water; heating the water before, during, or after being mixed with the hydrocarbon sands; increasing the pressure within a closed vessel containing the heated hydrocarbon and water mixture in the presence of gas or by injecting with gas; releasing the pressure of the heated hydrocarbon and water mixture in the vessel so as to create microbubbles from the dissolved gas in the water mixture; and collecting the hydrocarbon from the water. Optionally, the process is substantially devoid of adding caustic agents to the hydrocarbon and water mixture.Type: ApplicationFiled: October 31, 2008Publication date: December 9, 2010Inventors: Andy Hong, Zhixiong Cha

Publication number: 20100276341Abstract: A system and method of recovering heat and water from a slurry, such as tailings from oil sands extraction, is provided. The method includes providing the tailings to a humidification vessel, adding a sufficiently dry gas directly to the slurry in the vessel to form warm, water-saturated gas, such that heat and water are recovered from the slurry, removing the warm, water-saturated gas from the humidification vessel, providing the warm, water-saturated gas to a direct contact condensation vessel, cooling the gas in the condensation vessel to condense the water from the gas, thereby extracting water from the warm, water-saturated gas and recycling the dry gas, and recovering the water from the condensation vessel. Water which is of high quality, suitable for steam generation is obtained by a method in accordance with the present invention.Type: ApplicationFiled: October 9, 2008Publication date: November 4, 2010Inventors: Brian C.
