Abstract:
A pressure exchanger for transferring pressure from a first fluid at high pressure to a second fluid at a lower pressure, comprising a pressure housing; and a pressure exchanger assembly disposed within the pressure housing; the pressure exchanger assembly comprising a generally cylindrically-shaped liner having first and second end covers located thereon, each end cover having one or more fluid passageways for fluid communication with an interior of the cylindrical liner; and a rotor disposed within the interior of the liner for rotation about a longitudinal access, the rotor having a plurality of channels therethrough positioned for fluid communication with said passageways within said end covers during rotation of the rotor; the pressure housing having a first inlet for communicating the first high pressure fluid to a passageway in the first end cover and having a second inlet for communicating the second lower pressure fluid to a passageway in the second end cover; and a sealing ring disposed about the second end cover for sealing engagement with the pressure housing, the sealing ring defining a high pressure area between the exterior of the liner and the pressure housing and a low pressure area adjacent to the second end cover.
