  • Patent number: 8414692
    Abstract: Apparatus and method for separating a fluid. The apparatus includes an inlet duct having an inlet flow entrance and an inlet flow exit, the inlet duct defining an inlet width that decreases between the inlet flow entrance and the inlet flow exit, and an inlet radius that increases between the inlet flow entrance and the inlet flow exit. The apparatus also includes a separating turn fluidly connected to the inlet flow exit of the inlet duct and including an outer surface defining an opening. The apparatus further includes a liquid outlet fluidly connected to the opening of the separating turn to allow a higher-density component of the flow to exit the separating turn, and an outlet duct having an outlet flow entrance connected to the separating turn, to allow a lower-density component of the flow to exit the separating turn.

  • Patent number: 8408879
    Abstract: A fluid processing device for processing a multiphase fluid stream including a mixture of at least a gas and a liquid is disclosed. The fluid processing device may include at least one separator configured to separate the fluid stream into a liquid portion and a gaseous portion and deposit the liquid portion into a liquid reservoir. The gaseous portion may be directed to a compressor configured to pressurize and discharge a pressurized gas into a fluid discharge line. A portion of the pressurized gas may be further pressurized and directed to at least one ejector pump fluidly coupled to the liquid reservoir and configured to draw in liquid and discharge pressurized liquid into the fluid discharge line.

  • Publication number: 20130048577
    Abstract: A collection apparatus for a separator. The collection apparatus including a housing at least partially encircling a flow separation passage and defining a chamber and a cutout, the chamber being in fluid communication with the flow separation passage to receive a separated flow therefrom, and the cutout extending outward from the chamber to at least partially deflect the separated flow.

  • Patent number: 8286969
    Abstract: A seal ring for a rotatable shaft in a turbo machine includes a seal body configured for disposing around the shaft wherein a radial gap is defined between an inner surface of the seal body and the shaft. An upstream surface defined by the seal body extends from the inner surface, and an annular obstruction extends from the upstream surface of the seal body, wherein the obstruction is spaced away from the inner surface.

  • Publication number: 20110220591
    Abstract: A separator method and apparatus that includes a rotatable drum defining an annular passageway therein, a plurality of blades coupled to the rotatable drum and located in the annular passageway, each of the plurality of blades including a leading section, a trailing section, a concave surface, and a convex surface, the concave and convex surfaces extending from the leading section to the trailing section, each of the plurality of blades disposed circumferentially adjacent to at least another one of the plurality of blades so as to define blade flowpaths therebetween, and a housing at least partially surrounding the rotatable drum and defining a fluid collection chamber fluidly communicating with the annular passageway.
