  • Patent number: 10260820
    Abstract: A pumped heat energy storage system is provided. The pumped heat energy storage system may include a charging assembly configured to compress a working fluid and generate thermal energy. The pumped heat energy storage system may also include a thermal storage assembly operably coupled with the charging assembly and configured to store the thermal energy generated from the charging assembly. The pumped heat energy storage system may further include a discharging assembly operably coupled with the thermal storage assembly and configured to extract the thermal energy from the thermal storage assembly and convert the thermal energy to electrical energy.

  • Publication number: 20190010869
    Abstract: Systems and methods for cooling one or more components of a gas turbine are provided. One system may include an expansion device and one or more conduits. The expansion device may be operatively coupled to the gas turbine and configured to convert a pressure drop of a stream of compressed process fluid to mechanical energy. The expansion device may be further configured to at least partially drive the gas turbine with the mechanical energy. The one or more conduits may fluidly couple the expansion device and the gas turbine. The one or more conduits may be configured to direct an expanded stream of the compressed process fluid to the one or more components of the gas turbine to cool the one or more components.

  • Publication number: 20180291927
    Abstract: An internally-cooled compressor is provided including a casing and a diaphragm disposed in the casing. The diaphragm includes a diaphragm box defining a plurality of box channels and a bulb defining a plurality of bulb channels. A plurality of return channel vanes connect the diaphragm box and bulb in fluid communication, such that each return channel vane defines a plurality of return vane conduits coupled in fluid communication with the plurality of box channels and the plurality of bulb channels thereby forming a section of a cooling pathway. The cooling pathway is configured such that a cooling agent introduced from an external coolant source into the diaphragm box and flowing through a box channel flows through a return vane conduit into and through a bulb channel and back through another return vane conduit into another box channel before flowing back to the external coolant source.

  • Publication number: 20180274550
    Abstract: An internally-cooled diaphragm for an internally-cooled compressor is provided. The internally-cooled diaphragm may include an annular body configured to cool a process fluid flowing through a fluid pathway of the internally-cooled compressor. The annular body may define a return channel of the fluid pathway, and a cooling pathway in thermal communication with the fluid pathway. The return channel may be configured to at least partially diffuse and de-swirl the process fluid flowing therethrough, and the cooling pathway may be configured to receive a coolant to absorb heat from the process fluid flowing through the return channel.

  • Patent number: 9938895
    Abstract: A method for operating a compressed air energy storage system is provided. The method can include compressing a process gas with a compressor train to produce a compressed process gas and storing the compressed process gas in a compressed gas storage unit. The method can also include extracting the compressed process gas from the compressed gas storage unit to an expansion assembly through a feed line. A valve assembly fluidly coupled to the feed line can be actuated to control a mass flow of the compressed process gas from the compressed gas storage unit to the expansion assembly. The method can further include heating the compressed process gas in a preheater fluidly coupled to the feed line upstream from the expansion assembly, and generating a power output with the expansion assembly.

  • Publication number: 20170350318
    Abstract: A hybrid compressed air energy storage system is provided. A method of operation thereof includes compressing air during a storage period, and extracting thermal energy therefrom to produce a cooled compressed air. The cooled compressed air may be stored in an air storage unit, the extracted thermal energy may be stored in a thermal storage device, and the stored cooled compressed air may be heated with the stored extracted thermal energy to produce a heated compressed air during a generation period. The heated compressed air may be expanded with an expander to generate power and discharge an expanded air, which may be heated with a recuperator to produce a heated expanded air. A fuel mixture including the heated expanded air may be combusted to produce an exhaust gas, which may be expanded with a second expander to generate power and discharge the expanded exhaust gas to the recuperator.

  • Publication number: 20170010042
    Abstract: A method for producing liquefied natural gas (LNG) is provided. The method may include feeding natural gas from a high-pressure natural gas source to a separator and removing a non-hydrocarbon from the natural gas. A portion of the natural gas from the separator may be precooled, and the precooled natural gas may be cooled in a first heat exchanger with a first refrigeration stream. A first portion of the cooled natural gas may be expanded in a turbo-expander to generate the first refrigeration stream. A second portion of the cooled natural gas may be cooled in a second heat exchanger with the first refrigeration stream and expanded in an expansion valve to produce a two-phase fluid containing the LNG and a vapor phase. The LNG may be separated from the vapor phase in a liquid separator and stored in a storage tank.

  • Publication number: 20160252298
    Abstract: A method for producing liquefied natural gas (LNG) and separating natural gas liquids (NGLs) from the LNG is provided. The method may include compressing natural gas to compressed natural gas, removing a non-hydrocarbon from the compressed natural gas, and cooling the compressed natural gas to a cooled, compressed natural gas. The method may also include expanding a first portion and a second portion of the cooled, compressed natural gas in a first expansion element and a second expansion element to generate a first refrigeration stream and a second refrigeration stream, respectively. The method may further include separating a third portion of the cooled, compressed natural gas into a methane lean natural gas fraction containing the NGLs and a methane rich natural gas fraction. The methane rich natural gas fraction may be cooled in a liquefaction assembly with the first and second refrigeration streams to thereby produce the LNG.
