Hybrid pressure and thermal exchanger

Abstract

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.
