Patent number: 6732055Abstract: Methods, systems, and processes are disclosed for determining emissions outputs. One method communicates with a communications network and acquires at least one of energy usage information associated with sources of emissions and emissions information associated with sources of emissions. The energy usage information and the emissions information is acquired as each occurs in real time. The method reports emissions outputs based upon the acquired real time information. Another method communicates with a communications network and acquires at least one of energy usage information associated with sources of emissions and emissions information associated with sources of emissions. This embodiment stores the acquired information as each occurs in real time. Emissions outputs are reported for the industrial process, the emissions outputs based upon the acquired real time information.Type: GrantFiled: November 6, 2001Date of Patent: May 4, 2004Assignee: General Electric CompanyInventors: Srinivas Krishnasnamy Bagepalli, Lynn Ann DeRose, Stephen Lan-Sun Hung, Bang Mo Kim, Tara Healy Wight, Joseph James Salvo

Patent number: 6641722Abstract: A method of removing silicone oils from waste water generated by a silicones manufacturing plant including the step of centrifuging the waste water to concentrate silicone oil contaminated solids while removing the silicone oils. The silicone oil contaminated solids are then dried in a continuously mixed sludge dryer to remove more silicone oils from the sludge to form a sludge product which comprises at least 10% water and a low silicone oil concentration.Type: GrantFiled: September 17, 2001Date of Patent: November 4, 2003Assignee: General Electric CompanyInventors: Amy Rene Freshour, Stephen Lan-Sun Hung, Bang Mo Kim, Mark Allan Moses, Alan Frederick North, Don Royall Houston

Patent number: 6587754Abstract: A steam-generation management system remotely measures amounts of utility used by steam-generating systems; monitors and compares their performance against benchmarked performance; analyzes and determines causes for variances in their performance; and recommends to the steam user actions for achieving optimum operation. The steam-generation management also permits remote access and interaction by the user and allows for integrating steam-related information into an overall strategy for managing steam and energy supply.Type: GrantFiled: March 19, 2001Date of Patent: July 1, 2003Assignee: General Electric CompanyInventors: Stephen Lan-Sun Hung, Tara Healy Wight, Bang Mo Kim, Lynn Ann DeRose, Srinivas Krishnashamy Bagepalli, Jeffrey Lynn Schworm, Michael Edward Heeran

Publication number: 20030098367Abstract: A method and apparatus for depositing a uniform coating on a large area, planar surface using an array of multiple plasma sources and a common reactant gas injector. The apparatus includes at least one array of a plurality of plasma sources, wherein each of the plurality of plasma sources includes a cathode, an anode, and an inlet for a non-reactive plasma source gas disposed in a plasma chamber, and a common reactant gas injector disposed in a deposition chamber that contains the substrate. The common reactant gas injector provides a uniform flow of at least one reactant gas to each of the multiple plasmas generated the multiple plasma sources through a single delivery system. The at least one reactant gas reacts with the plurality of plasmas to form a uniform coating on a substrate.Type: ApplicationFiled: November 27, 2001Publication date: May 29, 2003Applicant: General Electric CompanyInventors: Amy Rene Freshour, Stephen Lan-Sun Hung, Jeffrey Lynn Schworm, Robert Arthur Wood

Publication number: 20030088527Abstract: Methods and systems are disclosed for determining water usage for industrial facilities and residences. One method communicates with a communications network and acquires water usage information. The water usage information is acquired in real time. The method reports water usage based upon the acquired water usage information. Another embodiment acquires water usage information over a communications network. This embodiment acquires real time water usage information over the communications network at a computer. The water usage information is associated with water use of an industrial facility. The embodiment may then display the real time water usage information via a user interface on the computer.Type: ApplicationFiled: November 6, 2001Publication date: May 8, 2003Applicant: General Electric CompanyInventors: Stephen Lan-Sun Hung, Timothy Mark Sivavec, James Rulon Young Rawson, Srinivas Krishnasnamy Bagepalli, Joseh Shoulian Zhu, Bang Mo Kim, Frank John Mondello, Lynn Ann DeRose, Joseph James Salvo, Richard Blair Sheldon

Publication number: 20030085179Abstract: Methods and systems are disclosed for reducing wastes produced from an industrial process. One embodiment describes communicating with a communications network and acquiring process information concerning the industrial process. A process parameter, associated with a predicted waste output, is predicted according to a predetermined model and based on the process information. The process parameter is then communicated over the communications network.Type: ApplicationFiled: November 6, 2001Publication date: May 8, 2003Applicant: General Electric CompanyInventors: Bang Mo Kim, Stephen Lan-Sun Hung, Joseph James Salvo

Patent number: 6432368Abstract: The ammonia content of fuel gas in an IGCC power generation system is reduced through ammonia decomposition, thereby reducing the NOx emissions from the plant. The power generation system includes a gasifier, a gas turbine and at least one catalytic reactor arranged between the gasifier and the gas turbine. The catalytic reactor may be either a three stage or two stage device. The three stage reactor includes a first catalyst which promotes water-gas-shift, a second catalyst which promotes CO methanation, and a third catalyst which promotes ammonia decomposition. The two stage reactor includes a first catalyst which promotes water-gas-shift and CO methanation and a second catalyst which promotes ammonia decomposition. The plural catalytic stages may be disposed in a single vessel or successively disposed in individual vessels, and the catalysts may be in a pelletized form or coated on honeycomb structures.Type: GrantFiled: June 30, 1994Date of Patent: August 13, 2002Assignee: General Electric CompanyInventors: Alan S.

Patent number: 6339925Abstract: A hybrid combustor, for providing stable high and low levels of operation while minimizing emissions of NOx, CO, and UHCs, includes a casing having a chamber, a catalytic combustor disposed in the chamber, and a non-premixed combustor disposed in the chamber. The hybrid combustor may comprise a fuel nozzle comprising a casing having a chamber, and a body supportable in the chamber to define a passageway between the body and the casing. The passageway has an inlet for receiving a stream of air and an outlet for discharging a stream of fuel and air, and the body includes a tapering downstream portion. Desirably, flow separation of the fuel and air mixture from the body (i.e., recirculation of the fuel and air mixture in the passageway and/or chamber) is inhibited whereby a generally uniform fuel and air mixture is provided.Type: GrantFiled: November 2, 1998Date of Patent: January 22, 2002Assignee: General Electric CompanyInventors: Stephen Lan-Sun Hung, Jeffery Alan Lovett, Kenneth Winston Beebe, Martin Bernard Cutrone, Sanjay Marc Correa

Patent number: 5395235Abstract: This invention relates to the use of a catalytic preburner for heating the pair from compressor discharge temperatures to above the light-off or extinction temperatures of a catalytic combustor. Such structures of this type, generally, eliminate the diffusion flame during steady-state operation and produce a preburner/catalytic combustor system capable of achieving less than 1 ppm NO.sub.x.Type: GrantFiled: July 27, 1994Date of Patent: March 7, 1995Assignee: General Electric CompanyInventor: Stephen Lan-Sun Hung
