    Abstract: Systems and methods for protecting a turbomachine may include a trip throttle valve having a throttle valve assembly and a trip valve assembly. The trip valve assembly may include a plurality of trip valves fluidly coupled to a hydraulic cylinder of the throttle valve assembly via a first flow path and a second flow path in parallel with one another. The trip valve assembly may also include a plurality of isolation valves fluidly coupled to the hydraulic cylinder via the first flow path and the second flow path. The plurality of isolation valves may be configured to selectively prevent fluid communication between the plurality of trip valves and the hydraulic cylinder to allow testing of one or more of the plurality of trip valves during operation of the turbomachine.

    Abstract: A system for attenuating acoustic energy in machines is provided. The system may include an inner tube disposed about a central axis, an outer tube disposed about the inner tube and the central axis, and a middle tube disposed about the central axis and between the inner tube and the outer tube. The system may also include a first annular ring extending radially from the outer tube and configured to couple the outer tube to the middle tube. The system may further include a second annular ring extending radially from the inner tube and configured to couple the inner tube to the outer tube, such that an acoustic resonator may be formed by the first annular ring, the second annular ring, a portion of the inner tube, a portion of the outer tube, and a portion of the middle tube.

    Abstract: A poppet valve assembly including a valve seat defining at least one inlet port configured to receive a working fluid, a valve guard coupled to or integral with the valve seat and defining at least one outlet port configured to discharge the working fluid therefrom, and a valve member disposed in a guide pocket defined in the valve guard. The valve member may include a primary impact surface configured to contact a planar surface of the valve guard facing the valve seat. The valve member may also include a secondary impact surface configured to contact a bottom portion of the valve guard within the guide pocket after a structural failure of the primary impact surface prevents substantially all of the primary contact surface from contacting the planar surface.

    Abstract: An expander may include a longitudinal axis, an inner casing split horizontally along the longitudinal axis, an outer casing split horizontally along the longitudinal axis and spaced radially outward from and encompassing the inner casing. Each axial end of the outer casing may form a respective gland seal housing, and the outer casing and inner casing may define an exhaust chamber therebetween. A plurality of expansion stages including a rotor shaft may be disposed within the inner casing and configured to expand the working fluid received from a working fluid source. A plurality of seals may be disposed within each of the gland seal housings and mounted circumferentially about the rotor shaft. The plurality of seals may include an annular seal, a plurality of dynamically self-adjustable seals disposed outboard of the annular seal, and at least one dry gas seal disposed outboard of the plurality of dynamically self-adjustable seals.

    Abstract: A “bolt on” static separator is disclosed for use in conjunction with a rotating separator to handle higher liquid volumes that are not able to be effectively separated by the rotating separator alone. The static separator may be positioned upstream of the rotating separator, generally right in front of the rotating separator, i.e., immediately ahead of the inlet to the rotating separator and generally attached directly to the front end of the rotary separator. The static separator may include a significant change in flow path direction that is sufficient to cause coarse fluid separation. The output of the static separator is in communication with the input of the rotating separator. Additionally, the drain of the static separator is in communication with the drain of the rotating separator and is at the same pressure.
