Patent number: 9011697Abstract: A method for the treatment of fluid including the step of exposing the fluid to a pulsed plasma discharge. The pulsed plasma discharge will be generated using a suitable electrode configuration to generate the plasma discharge in the fluid. Apparatus useful in the method may include a vessel, at least two electrodes for generating a plasma discharge in water, and a flow inlet and a flow outlet to allow water to be passed through the vessel. Also described is an in-line water treatment, where a pulsed plasma discharge is used in a pipe carrying moving water. Plasma based fluid treatment system may have many advantages in comparison to other treatment methods, such as very minimal maintenance, low operating power, and minimal pressure loss through the device.Type: GrantFiled: June 15, 2007Date of Patent: April 21, 2015Assignee: Drexel UniversityInventors: Christopher A. Campbell, Young I. Cho, Alexander F. Gutsol, Alexander Fridman, Frank T. Snyder, Vincent Szarko, Erik Yelk, Jesse Zanolini, Victor Vasilets

Publication number: 20140332385Abstract: A method and apparatus for separating drilling fluid is provided. A housing is provided with a number of vertical parallel spaced apart electrode plates within. The housing is filled with a batch of drilling fluid so that the drilling fluid fills up the spacings between the electrode plates and the drilling mud is subjected to an electro-separation cycle by placing a DC voltage across the electrode plates so that adjacent plates have opposite polarity and an electric field is created in the drilling fluid in the spacings between the electrode plates. During the electro-separation cycle, periodically subjecting the drilling fluid to a vibration cycle by inducing vibrations in the drilling fluid. When the treatment of the drilling fluid is completed, removing an upper layer of fluid from the housing.Type: ApplicationFiled: May 8, 2013Publication date: November 13, 2014Inventors: Sean Frisky, Jason Beaudin, Justin Lee, Joel Wolensky

Patent number: 8597513Abstract: The present invention is directed to a method for cleansing fuel processing effluent containing carbonaceous compounds and inorganic salts, the method comprising contacting the fuel processing effluent with an anode of a microbial fuel ell, the anode containing microbes thereon which oxidatively degrade one or more of the carbonaceous compounds while producing electrical energy from the oxidative degradation, and directing the produced electrical energy to drive an electrosorption mechanism that operates to reduce the concentration of one or more inorganic salts in the fuel processing effluent, wherein the anode is in electrical communication with a cathode of the microbial fuel cell. The invention is also directed to an apparatus for practicing the method.Type: GrantFiled: February 6, 2009Date of Patent: December 3, 2013Assignee: UT-Battelle, LLCInventors: Abhijeet P. Borole, Constantino Tsouris

Publication number: 20130090488Abstract: The present invention is directed to solubilizing compounds, a device and a method for solubilizing and removing carboxylic acids and especially fatty acids from oils, fats, aqueous emulsion, aqueous media and organic solutions. Devices utilizing the inventive method shall be used for separating carboxylic acids from oils, fats, aqueous emulsion, lipophilic media or organic solutions, respectively by preparing an aqueous micro- or nanoemulsion of the carboxylic acids especially the fatty acids and the solubilizing compound which contains at least one amidino and/or gianidino group. Solubilization effects of solubilizing compounds combined with the inventive use of separation methods for carboxylic acids can be used to treat persons in need of removal of fatty acids or analyze carboxylic acids from blood or process other solutions in food, pharmacy, chemistry, bio fuel industry or other industrial processings.Type: ApplicationFiled: June 22, 2011Publication date: April 11, 2013Inventor: Ulrich Dietz

Patent number: 7686933Abstract: An apparatus for electrophoretically removing contaminants from an oil-based drilling fluid includes a housing, a drum, a means for rotating the drum, and a scraper head. The drum is retained within the housing above the housing floor. The oil-based drilling fluid is directed along the housing floor, contacting both the housing floor and the drum. A negative charge is applied to the drum and a positive charge is applied to the housing, creating an electrical field through the fluid. Drilling fluid contaminants are attracted to and collect upon the drum outer surface. The means for rotating the drum turns the drum through the fluid and collected contaminants remain on the drum outer surface. The scraper removes the collected contaminants from the drum outer surface as it rotates.Type: GrantFiled: December 16, 2005Date of Patent: March 30, 2010Assignee: M-I L.L.C.Inventors: Neale Browne, Catalin Ivan, Zoran Markanovic

Patent number: 7378012Abstract: A method for reforming a lubricating oil which includes holding stably a container (6) containing a lubricating oil (5) on a stand (4) being insulated from the earth with four high-voltage insulators (3), and applying an electrostatic potential of 30 to 50 volts by the use of an electrostatic charge generating device (7), to thereby charge electrons to the lubricating oil (5). The charge of electrons converts an unsaturated hydrocarbon (1a) and an aromatic hydrocarbon (2a) in the lubricating oil (5) to a saturated hydrocarbon (1b) or (2b) and a naphthenic hydrocarbon (2c), which reduces the viscosity of the lubricating oil. Accordingly, the use of the lubricating oil (5) in an internal combustion engine lowers the friction resistance therein, which leads to a decrease in the fuel consumption of the engine. The method allows, therefore, the enhancement of fuel economy, in combination with the suppression of oxidation of the lubricating oil itself.Type: GrantFiled: November 19, 2002Date of Patent: May 27, 2008Inventor: Naoto Yokoo

Patent number: 5843301Abstract: A process and system for converting petroleum residue ("resid") into a liquid product and a solid product. The resid is first mixed with a solvent having a generally nonpolar molecular character. A strong electric field is then applied to the mixture to agglomerate the asphaltenes and other large molecules in the resid. The agglomerates are then separated from the remaining liquid, thereby producing liquid and solid products. The liquid product is useful as a feedstock for petrochemicals and transportation fuels, and the solid product is suitable for combustion as a coal substitute. A portion of the liquid product may be recycled as the solvent.Type: GrantFiled: October 9, 1996Date of Patent: December 1, 1998Assignee: OCET CorporationInventors: Ernest P. Esztergar, John L. Remo

Patent number: 5817228Abstract: The invention is a method for demetallating petroleum streams by subjecting a hydrocarbon soluble metals-containing petroleum stream and an aqueous electrolysis medium to a sufficient anodic potential at a pH sufficient to produce a treated petroleum stream having a decreased metals content. The invention is useful for enhancing the value of petroleum streams that traditionally have limited use in refineries due to their content of metals, particularly Ni and V.Type: GrantFiled: December 20, 1996Date of Patent: October 6, 1998Assignee: Exxon Research and Engineering CompanyInventors: Mark Alan Greaney, Michael Charles Kerby

Patent number: 5746907Abstract: A method is provided to remove metals from a residual oil containing an initial amount of a selected metal, the method comprising the steps of:providing a vessel for exposing the residual oil to a DC electric field having a strength of about one kV/inch or greater,passing the residual oils through the vessel whereby at least ten percent by weight of the initial amount of the selected metal is removed by attraction to an electrode; andpassing the residual oil that has been passed through the vessel over a hydrodemetalization catalyst in the presence of hydrogen. Metal containing particles and other toluene insoluble organic and inorganic solids are effectively removed from residual oil streams by treatment with a DC electrical field prior to hydrodemetalization resulting in significant increases in useful lives for downstream hydrodemetalization catalyst.Type: GrantFiled: February 20, 1996Date of Patent: May 5, 1998Assignee: Shell Oil CompanyInventors: Antonius Franziskus Heinrich Wielers, Vitold Raimond Kruka
