Abstract
Official abstract text for this publication.
A system including a rotary isobaric pressure exchanger (IPX) configured to exchange pressures between a first fluid and a second fluid, and a motor system coupled to the hydraulic energy transfer system and configured to power the hydraulic energy transfer system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system, comprising: a rotary isobaric pressure exchanger (IPX) configured to exchange pressures between a first fluid and a second fluid, wherein the rotary IPX comprises a rotor, the rotor comprises ducts extending longitudinally through the rotor, and the first fluid and the second fluid directly contact each other within a respective duct to exchange pressures, wherein the first fluid is a substantially particulate free fluid and the second fluid is a particulate laden fluid: and an electric motor coupled to the rotary IPX and configured to power the rotary IPX, wherein the electric motor comprises first permanent magnets or first electromagnets within the rotor of the rotary IPX configured to interact with second permanent magnets or second electromagnets. 2. The system of claim 1 , wherein the second permanent magnets or second electromagnets couple to a shaft that extends through the rotor. 3. The system of claim 1 , comprising a controller with one or more modes of operation configured to control the motor system, wherein the one or more modes of operation comprise at least one of a startup mode, a speed control mode, a continuous power mode, or a periodic power mode.
