Patent number: 8096425Abstract: An extraction system and process for extracting bitumen from a slurry containing bitumen, solids and water. The system comprises a cyclone separation facility for separating the slurry into a solids component stream and a bitumen froth stream with the bitumen froth stream including water and fine solids. The bitumen froth stream is then delivered to a froth concentration facility for separating the bitumen froth stream into a final bitumen enriched froth stream, and a water and fine solids stream. The final bitumen enriched froth stream is suitable for further processing.

Publication number: 20100193418Abstract: Methods, systems, drain vaults, and tools are employed to treat storm water runoff from a watershed. The methods and system may include multiple drain vaults that function to receive and allow quiescence of the water so that laminate flow may be achieved between adjacent vaults. The drain vaults may be made of stacked together vault sections held in compression, and screens and arrays of tube elements are with different drain vaults. There may be combined systems where in an upstream system flow is uncontrolled during a rainstorm and some of the rainfall water is diverted to a retention structure and then in a control flow rate is transferred to a downstream treatment system that may use tube elements. A tool is used to clean the tube elements.Type: ApplicationFiled: January 29, 2010Publication date: August 5, 2010Inventor: David Belasco

Patent number: 7740757Abstract: An exemplary apparatus (20), for removing pollutants atop a body of coolant, includes a filter (21), a pollutant removing structure (22), and a pump (23). The filter includes a housing (210), and a filtering unit (211) positioned in the housing for removing the pollutants from the coolant. The filtering unit is separated into a first cavity (2112) and a second cavity (2113) by a partition sheet (213). The partition sheet is spaced apart from a bottom surface of the housing to define a communicating gap (2131) for the first cavity and the second cavity to communicate with each other. The pollutant removing structure is positioned on the filter. The pollutant removing structure includes a removing member (221) for removing the pollutants out of the filter. The pump is configured for pumping the coolant into the first cavity of the filter.Type: GrantFiled: May 26, 2008Date of Patent: June 22, 2010Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Ming-Lu Yang, Wei-Guo Yang, Zheng-Hong Chi, Yu-Jun Wang

Patent number: 7740752Abstract: A system for separating suspended and dissolved materials in a fluid having a pH offset from neutral is disclosed. It employs a plurality of stacked, generally flat treatment beds each having a surface angled downward for receiving the fluid. Since the fluid is spread over a large surface, its velocity slows causing suspended materials to drop out of the fluid as a sludge. A pH correction device may add an agent to the flowing fluid which will bring the pH closer to neutral thereby causing said dissolved materials to precipitate out and into the sludge. Atmospheric oxygen may also be used to effect the precipitation. Portions of the beds may be isolated and the sludge collected resulting in a fluid having substantially less suspended and dissolved materials at a pH and temperature closer to normal. Energy may be produced from the movement of liquid through the system or from the heat energy of the fluid. Magnetics may be utilized to improve the precipitation of solids.Type: GrantFiled: August 8, 2007Date of Patent: June 22, 2010Inventor: Christopher S. Gillis

Patent number: 7736501Abstract: A system and process for concentrating hydrocarbons in a bitumen feed comprising bitumen, water and solids. The system comprises an inclined plate separator, a hydrocarbon cyclone and a centrifuge. The inclined plate separator separates the bitumen feed into a first overflow stream and a first underflow stream, the first overflow stream having a first bitumen concentration greater than that of the first underflow stream. The hydrocarbon cyclone separates the first underflow stream into a second overflow stream and a second underflow stream. The centrifuge separates the second overflow stream into a third overflow stream and a third underflow stream, the third overflow stream having a third bitumen concentration that is greater than that of the third underflow stream.Type: GrantFiled: June 6, 2007Date of Patent: June 15, 2010Assignee: Suncor Energy Inc.Inventors: William Nicholas Garner, Kim Jonathan Wiwchar, Ian Mackay Noble, Iain William Elder, Michael Fong-Yin Lam

Patent number: 7717275Abstract: An integrated perforated flocculating baffle system for use in a clarifier tank with a tank bottom, and a peripheral vertical wall bounding the interior of the tank is formed by a plurality of individual baffles interconnected and mounted to a support element, extending vertically inside the tank forming a rigid wall of perforated baffles allowing incoming water to pass through its openings and through gaps between individual baffles promoting flocculation of the suspended matter, and distributing the flow equally and uniformly throughout the settling the clarifiers. Each baffle includes solid linear and curved sections followed by perforated sections. The baffles are interconnected along the length by cross connectors to ensure rigidity. The resulting system provides an integrated perforated baffle system by which the water flows uniformly within the tank and flocculation is enhanced.Type: GrantFiled: May 27, 2008Date of Patent: May 18, 2010Inventor: Hany Zarif Gerges

Patent number: 7718056Abstract: Separator for removing impurities, especially smaller particles, from rain water. It comprises a first reservoir (2) and a second reservoir (6). The first reservoir (2) performs the function of removing the heaviest portions of the impurities, but is also provided with a lamellar device (4), wherein small drops and impurities of the rain water may be combined to larger impurity aggregates. The second reservoir (6) is divided into a first chamber (6a) and a second chamber (6b), said chambers communicating with each other. A tube (5) provided with perforations (5?) is arranged above the lamellar device (4), through which rain water containing impurities is able to flow from the first reservoir (2) and into the first chamber (6a). The first chamber (6a) is provided with a filter (9). In this way, a more efficient purification of rain water than using the known separator is provided.Type: GrantFiled: October 24, 2006Date of Patent: May 18, 2010Inventor: Arne Bonnerup
