Patent number: 8623221Abstract: A sand separator for capturing sand and rock debris from recovered natural gas fracturing fluid includes a cylindrical, high-pressure-rated vessel disposed vertically and immediately downstream of the gas wellhead. High pressure fracturing fluid enters the top of the separator into an inner flue extending coaxially downward to terminate a spaced distance above the bottom of the vessel. Transverse baffles spaced apart along the length of the flue extend through the flue to the inner walls of the vessel to keep the flue centered within the separator. As the fluid enters the separator, openings through the flue near the vessel inlet permit lighter weight and gaseous constituents to escape the fluid and bypass the flue, thereby reducing the velocity of the fluid remaining inside the flue. As the remaining fluid falls to the bottom of the vessel, it further slows as it reverses direction to rise between the flue and the vessel walls.Type: GrantFiled: April 27, 2011Date of Patent: January 7, 2014Inventors: Keith L.

The operating pressure of the treatment vessel may be regulated to remain within a desired range.Type: GrantFiled: April 30, 2012Date of Patent: July 9, 2013Assignee: Suncor Energy Inc.Inventor: Thomas Charles Hann

Patent number: 8475664Abstract: The overflow and underflow effluents of a conventional hydrocyclone are discharged into enclosed vessels, so that the operating pressure may be manipulated for each effluent independently of other operating parameters. Each of the effluent vessels is equipped with a source of pressurized gas to form a gas blanket over the effluent at a controllable pressure. Such variable pressures in each vessel, in combination with the pressure of the incoming feed stream, provide the necessary parameters to implement pressure-differential-ratio control, thereby improving the efficiency of separation.Type: GrantFiled: February 8, 2010Date of Patent: July 2, 2013Assignee: FLSmidth A/SInventors: Paul Martin Keyser, Timothy John Olson

Patent number: 8449779Abstract: The present disclosure provides a collection receptacle and a method for reclaiming backflow from a wellbore. The collection receptacle, in one embodiment, includes an enclosure configured to collect solid and liquid matter, and an elevated auger extending into the enclosure and configured to remove the solid matter from the enclosure. In this embodiment, the auger includes a housing and a flighting, the housing and flighting configured in such a way as to promote separation of the solid matter from the liquid matter as the solid matter travels up the auger and out of the enclosure.Type: GrantFiled: January 11, 2010Date of Patent: May 28, 2013Assignee: Granbury Thompson Group, LLCInventor: Bruce Thompson

Publication number: 20130118962Abstract: Systems and methods are provided for processing abrasive slurry used in cutting operations. The slurry is mixed with a first solvent in a tank. The slurry is vibrated and/or ultrasonically agitated such that abrasive grain contained in the slurry separates from the other components of the slurry and the first solvent. After the abrasive grain has settled to a bottom portion of the container, the other components of the slurry and the first solvent are removed from the tank. The abrasive grain may then be washed with a second solvent. The abrasive grain is then heated and is suitable for reuse in an abrasive slurry.Type: ApplicationFiled: January 3, 2013Publication date: May 16, 2013Applicant: MEMC ELECTRONIC MATERIALS, INC.Inventor: MEMC ELECTRONIC MATERIALS, INC.

Publication number: 20130118998Abstract: The present invention provides an apparatus, method and system for separating a first substance from a mixture of the first substance and a liquid. The apparatus comprises inlet means adapted to receive a portion of the mixture into a separator tank; a separator tank for holding a collected portion of the mixture and allowing the first substance to separate from the liquid due to the first substance having a different specific gravity to the liquid; and outlet means adapted to discharge the separated liquid and/or the first substance from the separator tank.Type: ApplicationFiled: May 13, 2011Publication date: May 16, 2013Inventor: Christopher Wood

Patent number: 8440087Abstract: A thickening tank has a peripheral overflow launder and a centrally disposed feed well. Feedstock slurry is fed to a mixing box which also receives supernatant liquid and is supplemented by flocculated material flowing into the interior of the feed well onto a distributor baffle plate. The supernatant liquid is delivered at a controlled rate from a receiving vessel formed by an upright cylinder provided at its lower end with an impeller of a lift pump which is operated by a controller positioned at the upper end of a vertical drive shaft extending axially through the receiving vessel. The feed well is surrounded by a second launder which is closed at its base and formed with a cup. The lower end of the receiving vessel is spaced from the floor of the cup to draw supernatant liquid exclusively from the second launder rather than from the thickener tank.Type: GrantFiled: December 2, 2008Date of Patent: May 14, 2013Assignee: Delkor Pty., LtdInventor: Rhett McElvenny

Patent number: 8431019Abstract: A wastewater treatment system includes an outer tank, an aeration chamber partition located within the outer tank and forming an aeration chamber, and a draft tube located within the outer tank and vertically extending into the bottom of the aeration chamber to communicate the aeration chamber with an outer chamber formed. A submerged aerator is located within the draft tube. An inlet communicates influent into the aeration chamber and an outlet communicates effluent out of the outer tank. A scum baffle prevents floating solids from entering the outlet. The outer tank has an effluent weir which supports the scum baffle and the scum baffle has an upward facing flange that supports the aeration chamber partition. An air intake pipe extending to the aerator through an upper end of the draft tube has support members engaging a top of the draft tube to support the aerator within the draft tube.Type: GrantFiled: May 17, 2010Date of Patent: April 30, 2013Assignee: Consolidated Treatment Systems, Inc.Inventors: Jeff Coomer, David Clinkscales, Jeff Luthman

Publication number: 20130087514Abstract: First and second liquids are separated from mixtures thereof in a holding tank that holds quantities of the two liquids after they have been separated and a quantity of the mixture that has not been separated. A first transfer conduit receives a pressurized mixture of the first and second liquids which is discharged into the holding tank. A venturi passageway is located in the first transfer conduit. A liquid conductor has an entry opening positioned so that at least a portion of the entry opening is located within the quantity of the mixture that is held in the holding tank and an exit opening that is in fluid communication with the venturi passageway. The increase in the velocity of the pressurized mixture flowing through the venturi passageway and the accompanying reduced pressure causes the mixture held in the holding tank to flow through the liquid conductor into the venturi passageway.Type: ApplicationFiled: October 11, 2011Publication date: April 11, 2013Applicant: ZEBRA SKIMMERS CORP.Inventor: Steven Davidian
