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.

Hydraulic energy transfer system with fluid mixing reduction

A hydraulic energy transfer system including an isobaric pressure exchanger (IPX) configured to exchange pressure between a first fluid and a second fluid. The IPX includes a channel formed by the IPX. The IPX is designed to direct the first fluid to a first opening of the channel and the second fluid to a second opening of the channel. The IPX further includes a barrier disposed within the channel. The barrier is designed to reduce mixing of the first fluid and the second fluid while exchanging pressure between the first fluid and the second fluid within the channel.

A pumping system that includes a reciprocating isobaric pressure exchanger (reciprocating IPX) designed to exchange pressures between a first fluid and a second fluid. The first fluid includes a substantially particulate free fluid and the second fluid includes a particulate laden fluid. The reciprocating IPX includes a valve having a first and second piston. The value further includes a shaft coupling the first piston to the second piston and a drive coupled to the shaft.

Frac system with hydraulic energy transfer system

A frac system that includes a hydraulic energy transfer system configured to exchange pressures between a first fluid and a second fluid.
