  • Publication number: 20240068745
    Abstract: A natural gas liquefaction system and method for effectively and efficiently removing heavy hydrocarbons and converting natural gas into liquefied natural gas. Natural gas streams entering the system may consist of varied gas compositions, pressures, and temperatures. In embodiments the system may comprise a natural gas (NG)-to-liquefied natural gas (LNG) portion and a closed-loop refrigeration portion comprising a closed-loop single mixed refrigerant system. In other embodiments the system may comprise an NG-to-LNG portion and a closed-loop refrigeration portion comprising a closed-loop gaseous nitrogen expansion refrigeration system. All embodiments utilize an integrated heat exchanger with cold-end and warm-end sections and integrated multi-stage compressor and expander configurations (e.g. compander) in order to increase overall operation flexibility and efficiency.

  • Publication number: 20210059642
    Abstract: The present disclosure related generally to ultrasound imaging, such as intravascular ultrasound imaging. For example, some embodiments of the present disclosure provide an ultrasound imaging system with improved acoustic impedance matching between an ultrasonic transducer and a vessel of interest. For example, in some implementations, an ultrasound imaging device includes a flexible elongate member and an ultrasound scanner assembly disposed at a distal portion of the flexible elongate member. The ultrasound scanner assembly includes a plurality of ultrasound transducers arranged circumferentially, and an impedance matching structure is coupled to the plurality of ultrasound transducers. In some such embodiments, the impedance matching structure is disposed radially outward from the plurality of ultrasound transducers, and in some embodiments, the impedance matching structure is disposed radially inward from the plurality of ultrasound transducers.
