A system exchanges pressure and heat from a source stream to a sink stream. The system includes a source exchanger and a sink exchanger. The source exchanger includes a first pressure exchanger and a first heat exchanger. The first pressure exchanger converts pressure of the source stream to electrical energy. The first heat exchanger converts temperature from the source stream via a first temperature differential to electrical energy. The sink exchanger includes a second pressure exchanger and a second heat exchanger. The second pressure exchanger uses electrical energy received from the source exchanger to change a pressure of the sink stream. The second heat exchanger uses electrical energy received from the source exchanger to change a temperature of the sink stream. Related apparatus, systems, techniques, and articles are also described.

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 gas compressor comprising a substantially hollow cylindrical drum secured to a fixed shaft and configured to rotate a volume of fluid about a central axis. A plurality of eductors may be affixed to the shaft through support rods and positioned within an interior of the drum to receive a flow of fluid during rotation of the drum. A gas inlet along the fixed shaft comprises a channel through which gas external to the drum may be drawn into the eductors and compressed. Compressed gas accumulates within a central area of the drum and may be harvested through a gas outlet along the fixed shaft. Additional embodiments may comprise pitot tubes to manage a fluid level within the drum, and a cooling system to manage fluid temperature.
