  • Publication number: 20140190172
    Abstract: A multi-stage, two-flow, axial flow expander close-coupled to a driven machine, such as a generator. The expander includes one or more expansion stages separated by a series of flow stream dividers that separate each expansion stage into outer and inner expander flowpaths. Working fluid at a first temperature is directed into the outer expander flowpath for expansion, and working fluid at a second, lesser temperature is directed into the inner expander flowpath for expansion. Expansion of the working fluid drives the driven machine.

  • Patent number: 8746464
    Abstract: A fluid separator includes a casing and a tubular main body disposed in the casing and having a central axis, inlet and outlet ends spaced along the axis, inner and outer circumferential surfaces; and drain passage(s) extending radially between the inner and outer surfaces. A collection chamber is defined between the outer surface and the casing and the inner surface defines a central flow passage, such that liquid contacting the inner surface flows through the drain passage(s) and into the collection chamber. A deflector disposed within the flow passage includes a hub located on the central axis with a bore and a plurality of vanes extending radially between the hub and the main body inner surface. Each vane has a first channeling surface facing toward the body inlet and a second channeling surface facing away from the inlet. Recirculation members fluidly connect the collection chamber with the hub bore.

  • Publication number: 20140109574
    Abstract: A heat engine system is disclosed and includes first and second condensers fluidly and structurally coupled to first and second recuperators. An expansion device is coupled to the condensers at a drive end and suspended from the recuperators at a non-drive end. The recuperators can be printed circuit heat exchangers which provide superior heat transfer capabilities but are also robust enough to support the expansion device, and thereby form an integral part of a structural baseplate for mounting and aligning various components of the heat engine system. Exhaust conduits extending between the expansion device and the recuperators also provide added structural support for the expansion device.

  • Patent number: 8657935
    Abstract: A method and system for expanding, separating, and compressing a multi-phase fluid. An expander receives and expands the multi-phase fluid to generate a lower-pressure fluid which can more efficiently be separated in a separator. Expanding the fluid also drives a main shaft adapted to drive at least the separator and a compressor coupled thereto. The separator receives the lower-pressure fluid, separates any higher-density components from the lower-density components disposed therein, and provides a substantially dry gas to the compressor to be re-compressed and discharged from the system.

  • Patent number: 8596292
    Abstract: A controlled flow drain having an upper flange coupled to a lower flange. The upper flange defines an inlet cavity and the lower flange defines a swirl chamber. The inlet cavity and swirl chamber are in fluid communication via a swirl nozzle defined within a swirl nozzle plate that separates the inlet cavity from the swirl chamber. After separating debris within the drain fluid, the drain fluid is accelerated through the swirl nozzle and discharged into the swirl chamber, and more debris is thereby separated and eventually settles into an annular groove. The drain fluid may then exit the lower flange via an exit control passage. The swirl chamber may be flushed with a series of flushing liquid injection ports symmetrically-arrayed about the annular groove. Flushing the swirl chamber removes fluidized debris and also remove any built up fouling present on the swirl nozzle and exit control passage.

  • Patent number: 8580002
    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.
