Patent number: 7033979Abstract: A composition and method for cleaning gas turbine engines to remove fuel or lubricant residues. The composition can include a mixture of hydrofluorocarbon and hydrofluoroether. The method can include the step of directing a pressurized stream of the cleaning composition against one or more portions of the gas turbine engine to remove fuel and/or lubricant residues.Type: GrantFiled: February 3, 2003Date of Patent: April 25, 2006Assignee: General Electric CompanyInventors: Mark Guenter Herwig, Mark Joseph Rechtsteiner, Roy Fred Thornton, Bruce Edward Goodwin

Patent number: 6858136Abstract: A method for treating silicone emulsion waste includes the steps of adding base chemical materials to the silicone emulsion waste in an amount effective to cause separating of the silicone emulsion waste. The added chemicals separate the silicone emulsion waste into silicone oil and an emulsion-free water. The components can be separated, with the silicone oil laden liquid being sent to an incinerator and the emulsion-free water being sent to a wastewater treatment plant. The base chemicals can include sodium hydroxide, sodium carbonate, sodium chloride and/or combinations thereof. To enhance separating of the silicone emulsion waste, the silicone emulsion waste can be heated prior to the addition of the chemicals. Also, by recycling the treated water and adding the same to the silicone emulsion waste and base chemicals separation of the silicone emulsion waste can be enhanced.Type: GrantFiled: August 7, 2001Date of Patent: February 22, 2005Assignee: General Electric CompanyInventors: Amy Rene Freshour, Bang Mo Kim, Roy Fred Thornton

Patent number: 6521810Abstract: The present invention provides a method for treating contaminated media. The method comprises introducing remediating ions consisting essentially of ferrous ions, and being peroxide-free, in the contaminated media; applying a potential difference across the contaminated media to cause the remediating ions to migrate into contact with contaminants in the contaminated media; chemically degrading contaminants in the contaminated media by contact with the remediating ions; monitoring the contaminated media for degradation products of the contaminants; and controlling the step of applying the potential difference across the contaminated media in response to the step of monitoring.Type: GrantFiled: June 27, 2001Date of Patent: February 18, 2003Assignee: General Electric CompanyInventors: Andrew Philip Shapiro, Roy Fred Thornton, Joseph James Salvo

Patent number: 6197187Abstract: A method for treating a contaminated media. The method comprises disposing electrodes at the contaminated media, injecting a salt-containing solution into contaminated media, applying an electric voltage between electrodes imposed peripherally to the region, forming ions from the salt-containing solution, and migrating the ions between the electrodes across the contaminated media. The ions of the salt-containing solution migrate into at least a portion of the contaminated media to treat the contaminated media.Type: GrantFiled: May 12, 1999Date of Patent: March 6, 2001Assignee: General Electric CompanyInventors: Roy Fred Thornton, Andrew Philip Shapiro, Timothy Mark Sivavec
