  • Patent number: 10646804
    Abstract: A flow conditioning device for conditioning a wet gas stream having a plurality of liquid droplets and a gas flow is presented. The flow conditioning device includes a first segment including a first convergent section configured to break the plurality of liquid droplets from a first size to a second size. Further, the flow conditioning device includes a second segment coupled to the first segment and including a second convergent section configured to break the plurality of liquid droplets from the second size to a third size.
    Type: Grant

  • Patent number: 9803480
    Abstract: A liquid ring turbine has a casing defining an interior chamber with a symmetry axis. A shaft, having an axis substantially parallel to the symmetry axis, is eccentrically positioned to the symmetry axis. An impeller is coupled to the shaft and is configured to rotate in a first direction. The impeller includes a plurality of vanes extending away from the shaft in a second direction at least partially opposite the first direction. The impeller rotates within a liquid ring enclosed in the casing such that a plurality of expansion chambers are defined. Each expansion chamber is defined between adjacent vanes and the liquid ring. A gas inlet port is in fluid communication with a first expansion chamber defining a first volume. A gas outlet port is in fluid communication with a second expansion chamber. The second expansion chamber defines a second volume that is greater than the first volume.

  • Patent number: 9255642
    Abstract: An aerodynamic seal assembly for a rotary machine includes multiple sealing device segments disposed circumferentially intermediate to a stationary housing and a rotor. Each of the segments includes a shoe plate with a forward-shoe section and an aft-shoe section having multiple labyrinth teeth therebetween facing the rotor. The sealing device segment also includes multiple flexures connected to the shoe plate and to a top interface element, wherein the multiple flexures are configured to allow the high pressure fluid to occupy a forward cavity and the low pressure fluid to occupy an aft cavity. Further, the sealing device segments include a secondary seal attached to the top interface element at one first end and positioned about the flexures and the shoe plate at one second end.

  • Patent number: 8936722
    Abstract: A method for assembling turbomachinery having combined particle separation device and flow regulating device is provided. The turbomachinery includes a casing; a compressor attached to an inside of the casing, the compressor having a shaft supported by bearings; and a cooling system mounted inside the casing and configured to cool the bearings of the compressor with a cooling fluid. The cooling system includes a particle separation device configured to separate particles from the cooling fluid, and a flow regulation device that fluidly communicates with the particle separation device without contacting the particle separation device. The flow regulation device is disposed adjacent to the particle separation device within a wall of the casing.

Each of the segments includes a shoe plate with a forward-shoe section and an aft-shoe section having multiple labyrinth teeth therebetween facing the rotor. The shoe plate is configured to allow a high pressure fluid to a front portion of the plurality of the labyrinth teeth and a low pressure fluid behind the plurality of the labyrinth teeth and further configured to generate an aerodynamic force between the shoe plate and the rotor. The sealing device segment also includes multiple bellow springs or flexures connected to the shoe plate and to a top interface element, wherein the multiple bellow springs or flexures are configured to allow the high pressure fluid to occupy a forward cavity and the low pressure fluid to occupy an aft cavity.
