Publication number: 20140158517Abstract: Produced water from fraccing operations is treated by removing contaminants that are contained therein by evaporating the produced water and feeding the evaporated produced water to a combustion chamber preferably along with an oxygen gas and a hydrocarbon fuel source to separate solids from vapors. The vapors are condensed to produce liquid water and waste gases and the liquid water is recovered for reuse or more environmentally friendly disposal. The waste gases may also be employed in a turbine or expander to produce electricity.Type: ApplicationFiled: December 10, 2012Publication date: June 12, 2014Inventor: Arthur I. Shirley

Publication number: 20140113841Abstract: Stable, gas-filled bubbles on the surface of proppant particles are formed by placing proppant in selected organic solvent having a much greater solubility of a selected gas compared to water, pressurizing the solvent with the selected gas, e.g., nitrogen, at pressures equal of greater than the operating pressure for a set time period to achieve saturation, and then replacing the solvent with water before reducing the pressure back to operating pressure level to create a local supersaturation near the solvent-solid interface, which will result in gas-filled bubble formation on the surface of proppant particles. The pressurized mixture of bubble surrounded proppant particles and water can then be combined with a respective fracturing fluid, e.g., slick water or carbon dioxide and/or nitrogen foam or an emulsion, which can be used in oil or gas producing wells to improve efficiency of hydraulic fracturing thereof.Type: ApplicationFiled: October 18, 2013Publication date: April 24, 2014Inventors: Arthur I. Shirley, Eugene Wexler, Patrick Schneider, Robin Watts

Publication number: 20130312976Abstract: A method for fraccing oil or gas wells to recover natural gas. Liquefied natural gas is vaporized to form a foam or dense fluid. The foam or dense fluid is compressed to high pressures. The high pressure natural gas foam or dense fluid is fed into the oil or gas well and once the well is pressurized to a pre-determined pressure and fracturing has begun, the flow of the foam or dense fluid is stopped. After a suitable period for fracturing to occur, the flow is reversed and the natural gas from the well and the foam or dense fluid fracturing fluid is recovered. The recovered and produced natural gas can be treated and made ready for use in other applications.Type: ApplicationFiled: May 20, 2013Publication date: November 28, 2013Inventor: Arthur I. Shirley

Patent number: 6190436Abstract: An ozone-oxygen gas stream is introduced into feed side of a membrane separation unit containing an elastomeric polymer membrane. Ozone-enriched gas passes through the membrane to a permeate zone and is contacted with an ozone-reactive substance-containing gas stream in the permeate zone, thereby oxidizing the substances or is removed from the permeate zone. Removal of the ozone-enriched gas from the permeate zone may be effected by purging the permeate zone with an inert gas and/or evacuating the permeate zone. Ozone-enriched gas removed from the permeate zone may be mixed with a liquid or gas stream which contains ozone-reactive substances in, for example, a venturi device, thereby oxidizing the substances.Type: GrantFiled: March 5, 1999Date of Patent: February 20, 2001Assignee: The BOC Group, Inc.Inventors: Wenchang Ji, Robert James Ferrell, Arthur I. Shirley

Patent number: 6125638Abstract: Hot optical fiber being drawn from a preform is cooled in a helium cooled heat exchanger by a two-stage process. In the first stage, in which the rate of draw of fiber through the heat exchanger is increased to the design draw rate, the rate of flow of helium to the heat exchanger is increased as the rate of draw of fiber is increased. Helium is withdrawn from the heat exchanger by a variable speed blower, and during the first stage the rate of withdrawal of helium from the heat exchanger is controlled primarily by the rate of flow of helium into the heat exchanger, and during the second stage, the rate of flow of helium to the heat exchanger is maintained constant and the rate of withdrawal is determined primarily by the pressure in the heat exchanger.Type: GrantFiled: August 21, 1998Date of Patent: October 3, 2000Assignee: The BOC Group, Inc.Inventors: Wenchang Ji, Arthur I. Shirley, Roger Meagher

Patent number: 6065306Abstract: Ammonia is purified by a membrane unit to concentrate ammonia and/or ammonia and moisture. Moisture is removed in a temperature-swing adsorption unit. The resultant product of such purification is then partially condensed to remove light components of other impurities and then partially vaporized to produce a pressurized ammonia product lean in heavy components. If the feed stream is processed through the membrane unit first, the permeate stream will be lean in such impurities as carbon dioxide, nitrogen and methane. Moisture and any carbon dioxide not removed in the membrane unit is then removed by the adsorption unit. The resultant stream produced by action of the membrane and adsorption units is then partially condensed to produce a liquid lean in light impurities. Such liquid is then partially vaporized within a product pressure vessel to produce ammonia vapor lean in heavy impurities and at a required operational pressure.Type: GrantFiled: May 19, 1998Date of Patent: May 23, 2000Assignee: The BOC Group, Inc.Inventors: Wenchang Ji, Arthur I. Shirley, Atul M. Athalye, Piotr J. Sadkowski
