US 2019/0145237 A1 · PRESSURE EXCHANGER MANIFOLDING

Abstract

An apparatus having a plurality of pressure exchangers. Each pressure exchanger includes a first conduit and a second conduit and is operable for pressurizing a low-pressure dirty fluid via a high-pressure clean fluid. Each first conduit conveys the high-pressure clean fluid into a corresponding one of the pressure exchangers and to an adjacent one of the pressure exchangers, and each second conduit conveys a pressurized dirty fluid out of a corresponding one of the pressure exchangers and from the adjacent one of the pressure exchangers. The first conduits collectively form at least a portion of a high-pressure clean fluid manifold distributing the high-pressure clean fluid among the pressure exchangers, and the second conduits collectively form at least a portion of a pressurized dirty fluid manifold combining pressurized dirty fluid collectively discharged from the pressure exchangers.
