Abstract
A system includes a pressure exchanger configured to exchange pressure between a first fluid and a second fluid. The system further includes a shaft at least partially disposed within the pressure exchanger. The system further includes an electric motor coupled to the shaft. The electric motor is configured to control fluid flow in the pressure exchanger. A controller is configured to receive sensor data from one or more sensors associated with the pressure exchanger and vary proportions of the first fluid and the second fluid entering the pressure exchanger to reduce mixing of the first fluid and the second fluid in the pressure exchanger.
