Patent number: 11674090Abstract: Processes involving the use of a dry sorbent injection (DSI) unit or slurry reagent injection (SRI) unit to remove sulfur compounds form flue gas are described. Flue gas from an FCC regenerator, for example, is used to make superheated steam and saturated steam. The flue gas is then sent to a DSI unit to remove the sulfur compounds, and then to an economizer (or heat exchanger) to heat boiler feed water or combustion air. Because the temperature is not reduced as much as with a wet scrubber process, additional energy can be recovered in the economizer.Type: GrantFiled: November 30, 2021Date of Patent: June 13, 2023Assignee: Honeywell International Inc.Inventors: Jan De Ren, William J.

Patent number: 11098649Abstract: High-pressure fan duct bleed air is used to pressurize a cavity between the fan duct inner wall and the inner wall thermal insulation blankets. The cavity is pressurized to prevent hot air from the nacelle core compartment from flowing under the insulation blankets and degrading the fan duct inner wall. Pressure regulating valves (PRV) allow better control of the cavity pressure during different phases of the flight profile and under different levels of insulation blanket seal degradation by passively controlling exit area from the cavity based on an established pressure limit. Moreover, the pressurization system can be implemented as a passive cooling system by increasing the mass flow rate into the cavity and then the core compartment to a level suitable for core compartment cooling.Type: GrantFiled: July 19, 2018Date of Patent: August 24, 2021Assignee: THE BOEING COMPANYInventors: Robert De Pau, Jr., Kimberly A.

Patent number: 8650876Abstract: Ammonia sometimes present in geothermal steam increases the solubility of hydrogen sulfide in the steam condensate produced by the surface condenser in a steam cycle geothermal power generating unit by reacting with the hydrogen sulfide to produce nonvolatile ammonium bisulfide. The condenser vent gas also produced contains carbon dioxide. Contacting the steam condensate with the condenser vent gas at a pressure slightly greater than atmospheric causes carbon dioxide to dissolve in the condensate, decreasing pH and converting bisulfide ion back to hydrogen sulfide. Subsequently exposing the acidified condensate to condenser vacuum strips the hydrogen sulfide from the condensate, eliminating the need for further chemical treatment of the condensate to prevent air pollution. Hydrogen sulfide partitioning performance is further improved by converting the hydrogen sulfide in the vent gas to sulfur dioxide before contacting it with the condensate.Type: GrantFiled: March 17, 2011Date of Patent: February 18, 2014Assignee: ChemTreat, Inc.Inventor: Oleh Weres

The low enthalpy dry steam resulting from work being done flows into the condenser through the vortex cores of fractal turbulence. Condensate exits the periphery of the workspace, ready to be pumped back into the Rankine cycle.

Patent number: 7926277Abstract: Disclosed is a method for operating a condenser of the type having a housing inside of which is disposed a bundle of water tubes, a steam inlet for steam to flow inside the housing for contacting the tube bundle for cooling, and having a stagnant air zone during operation wherein any air in-leakage preferentially collects and condensate in the air zone becomes subcooled. A trough or drain is placed beneath the stagnant air zone for collecting subcooled condensate from the stagnant air zone. Collected subcooled condensate is transported from the trough or drain in a pipe to said steam inlet. The transported condensate is injected with an injector for contacting with steam entering the condenser, whereby the injected condensate is heated by the steam for expelling dissolved oxygen in the injected condensate. Advantageously, the condenser is fitted with an array of temperature sensors at the stagnant air zone for determination of its presence and/or size.Type: GrantFiled: February 21, 2006Date of Patent: April 19, 2011Inventor: Joseph W. C. Harpster

Publication number: 20110067410Abstract: A reformation power plant generates clean electricity from carbonaceous material and high pressure CO2 which can be easily sequestered or utilized for a beneficial purpose, such as fuel production. The reformation power plant design utilizes a reformation process that reforms carbonaceous fuel with super-heated steam into a high-pressure gaseous mixture that is rich in carbon dioxide and hydrogen gas. This high-pressure gas exchanges excess heat with the incoming steam from a boiler and continues onward to a condenser. Once cooled, the high-pressure gas goes through a methanol separator, after which the CO2-rich gas is sequestered underground or beneficially re-used. The remaining hydrogen-rich gas is combusted through a gas turbine. The gas turbine provides power to a generator and also regenerative heat for the boiler. Finally, the generator converts mechanical energy into electricity, which is transferred to the electric grid.Type: ApplicationFiled: September 23, 2009Publication date: March 24, 2011Inventors: Robert M.

Patent number: 7895839Abstract: A combined circulation condenser for a steam cycle apparatus is disclosed. The steam cycle apparatus includes a steam generator with a port for receiving a fluid. The steam generator presents heat to the fluid to generate steam that is directed out another port, which presents the steam to a turbine to generate electrical power. The turbine has an outlet that directs an exhaust steam into a condenser. A fluid flow system is inside the condenser, which directs cooling water along a pathway through the condenser so that the cooling water cools the exhaust steam, forming condensate. A condensate pump collects and pumps the condensate along another pathway through the condenser so that the condensate can additionally cool the exhaust steam. Simultaneously, the exhaust steam warms the condensate. This pathway directs the condensate to a feed pump, which pumps the condensate back to the steam generator through the generator's input port.Type: GrantFiled: October 9, 2007Date of Patent: March 1, 2011Inventor: Steven Richard Miller

Publication number: 20100219805Abstract: An electrical power boosting apparatus includes a metal substrate having a monomolecular carbon-based film on first and second surfaces, a conductive core, a positive electrode at one end, and a negative electrode an opposite end and magnets positioned adjacent and in a spaced-apart relationship to the metal substrate, the magnets are oriented so that north and south poles of each magnet are matched with opposite poles of an adjacent magnet. Electrical power is boosted by passing an initial electric current having an initial voltage through the conductive core of the metal substrate and causing or allowing an interaction between the metal substrate, the monomolecular carbon-based film, and the magnets to produce a modified electric current having a final voltage that is greater than the initial voltage.Type: ApplicationFiled: May 12, 2010Publication date: September 2, 2010Inventor: Thomas C.
