Abstract
A system includes a rotary isobaric pressure exchanger (IPX) configured to exchange pressures between a first fluid and a second fluid. The rotary IPX includes a sleeve, a rotor disposed within the sleeve in a concentric arrangement, a first endplate disposed proximate to a first axial face of the rotor, a second endplate disposed proximate to a second axial face of the rotor, and a plenum. The plenum includes a radial gap between an outer lateral surface of the rotor and an inner surface of the sleeve, a first axial gap between the first axial face of the rotor and the first endplate, and a second axial gap between the second axial face of the rotor and the second endplate. The plenum is asymmetric about an axial midplane of the rotor. The system also includes a hydrostatic bearing system configured to route a bearing fluid to the plenum.
