  • Publication number: 20210404738
    Abstract: Described herein are methods and systems for liquefying natural gas using an open-loop natural gas refrigeration cycle; coil wound heat exchanger units suitable for cooling one or more feed streams, such as for example one or more natural gas feed streams, via indirect heat exchange with a gaseous refrigerant; and methods and systems for removing heavy components from a natural gas prior to liquefying the natural gas using an open-loop natural gas refrigeration cycle.

  • Publication number: 20210190419
    Abstract: A method of constructing a coil wound heat exchange module and transporting and installing the coil wound heat exchange module at a plant site, such as an natural gas liquefaction plant. A module frame is constructed and attached to a heat exchanger shell prior to telescoping of a coil wound mandrel into the shell. The module frame includes a lug and two saddles that remain attached to the shell throughout the process and when the heat exchanger is operated. The lug and saddles are constructed and located to stabilize the shell during construction, telescoping and transport (when in a horizontal orientation), and when the shell is installed at the plant site (in a vertical orientation). The lugs and saddles are adapted to allow for thermal expansion and contraction of the shell when it is transitioned from ambient to operating temperature and vice versa.

  • Publication number: 20060153068
    Abstract: Disclosed are systems and methods which provide high availability with respect to equipment deployed in a distributed system architecture. The distributed system architecture may comprise one or more equipment clusters of a plurality of processor-based systems cooperating to host one or more application servers. Redundancy is provided with respect to equipment of the equipment clusters to provide high availability with respect to equipment used in providing services of the application servers as well as to provide continuity of applications provided by the application servers. Various equipment elements of an equipment cluster may be provided different levels and/or types of redundancy. Other equipment elements of an equipment cluster may be provided different levels and/or types of redundancy.
