Patent number: 9752728Abstract: A cryogenic tank assembly includes a cryogenic tank having an internal volume that is configured to contain liquefied natural gas (LNG). The cryogenic tank includes an inlet and an outlet that are each fluidly connected to the internal volume. The assembly includes a recirculation conduit coupled in fluid communication between the inlet and the outlet. The recirculation conduit extends along a path between the inlet and outlet external to the internal volume of the cryogenic tank such that the path is configured to be exposed to an ambient environment of the cryogenic tank. The recirculation conduit is configured to: receive a flow of LNG from the internal volume through the outlet; transfer heat from the ambient environment to the LNG flow to change the LNG flow to a flow of natural gas; and inject the natural gas flow into the internal volume of the cryogenic tank through the inlet.Type: GrantFiled: December 20, 2012Date of Patent: September 5, 2017Assignee: General Electric CompanyInventors: Ching-Jen Tang, Laura Michele Hudy

Patent number: 9328601Abstract: An oil recovery system and method are disclosed. The system includes a solar power tower for receiving a first portion of water from a water treatment device. The solar power tower heats the first portion of water directly using solar radiation and generates a first steam. Further, the system includes a boiler for receiving a second portion of water from the water treatment device. The boiler heats the second portion of water and generates a second steam. Further, the system includes a flow control device coupled to the solar power tower and the boiler to receive at least one of the first steam and the second steam. The flow control device injects at least one of the first steam and the second steam to an oil field.Type: GrantFiled: April 30, 2013Date of Patent: May 3, 2016Assignee: General Electric CompanyInventors: Huijuan Chen, Stephen Duane Sanborn, Andrew Maxwell Peter, Laura Michele Hudy

Patent number: 9255664Abstract: A system in one embodiment includes a detection unit, a boil-off auxiliary power unit, and a controller. The detection unit is configured to detect a characteristic of a boil-off gas stream from a cryotank configured to hold a cryogenic fluid. The boil-off auxiliary power unit is configured to receive the boil-off gas stream and use the boil-off gas stream to provide auxiliary power to a vehicle system. The controller is configured to acquire information from the detection unit corresponding to the characteristic; determine, using the information acquired from the detection unit, an available boil-off auxiliary energy that is available from the boil-off auxiliary power unit; determine a mode of operation of the vehicle system; determine a required auxiliary energy for the vehicle system; and to operate the auxiliary power unit based on the available boil-off auxiliary energy, the mode of operation, and the required auxiliary energy.Type: GrantFiled: December 24, 2012Date of Patent: February 9, 2016Assignee: General Electric CompanyInventors: William Dwight Gerstler, Laura Michele Hudy, Chiranjeev Kalra

Patent number: 9188285Abstract: A system in one embodiment includes a mixing module, an oxidation module, and a heat exchanger. The mixing module is configured to receive and mix a boil-off gas stream from a cryotank. The oxidation module is configured to receive the mixed stream, and to oxidize the boil-off gas in the mixed stream to produce an exhaust stream. The heat exchanger is configured to exchange heat between streams passing through a first passage configured to receive at least a portion of the exhaust stream, and a second passage configured to receive a fluid including the boil-off gas. The heat exchanger is configured to heat the fluid including the boil-off gas and cool the at least a portion of the exhaust stream. The fluid including the boil-off gas is heated by the heat exchanger upstream of the oxidation module.Type: GrantFiled: December 24, 2012Date of Patent: November 17, 2015Assignee: General Electric CompanyInventors: Chiranjeev Kalra, William Dwight Gerstler, Laura Michele Hudy, Michael Jay Epstein, Vaibhav Bahadur

Patent number: 8778545Abstract: A system and method are provided for boosting overall performance of a fuel cell while simultaneously separating a nearly pure stream of CO2 for sequestration or for use in generating electrical power to further increase overall efficiency of the process. The system and method employ a heat exchanger system configured to generate a stream of fuel that is returned to the inlet of the fuel cell anode with a higher molar concentration of carbon monoxide (CO) and hydrogen (H2) fuel than was initially present in the fuel cell anode outlet.Type: GrantFiled: March 31, 2011Date of Patent: July 15, 2014Assignee: General Electric CompanyInventors: Matthew Alexander Lehar, Andrew Philip Shapiro, Bruce Philip Biederman, Vitali Victor Lissianski, Andrew Maxwell Peter, Matthew Joseph Alinger, Laura Michele Hudy, Roger Allen Shisler

Publication number: 20130239608Abstract: An incoming compressed gas, such as natural gas, is pre-cooled and the gas separated from any included liquid. The pre-cooled and separated gas is expanded using an expander to rapidly reduce pressure and corresponding temperature, as well as remove any components solidified by the temperature drop. An output stream from the expander, combined with other streams, is again gas/liquid separated. The output separated gas stream is sent through another expansion and gas/liquid separation, separating one or more other components, such that a final output gas is achieved. In the case of natural gas, the final output is, for example, methane, which may be fed back to cool the incoming gas prior to end use of the methane.Type: ApplicationFiled: April 23, 2013Publication date: September 19, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: Vitali Victor LISSIANSKI, Laura Michele HUDY, Roger Allen SHISLER, Paul Brian WICKERSHAM, Miguel GONZALEZ, Nikolett SIPOECZ, Doug HOFER

Publication number: 20130084794Abstract: A system for producing at least one of solid or liquid carbon dioxide includes a combustor configured to produce an exhaust gas containing carbon dioxide, a compressor configured to compress the exhaust gas and a heat exchanger configured to cool the exhaust gas. An expansion chamber is configured to allow the compressed exhaust gas to expand and form the solid or liquid carbon dioxide and to separate the solid or liquid carbon dioxide from a substantially CO2 depleted gas. A supply passage supplies the CO2 depleted gas to said heat exchanger and a storage chamber stores the solid carbon dioxide.Type: ApplicationFiled: September 29, 2011Publication date: April 4, 2013Inventors: Vitali Victor Lissianski, Laura Michele Hudy
