  • Patent number: 12729698
    Abstract: A pressure exchanger includes a rotor configured to exchange pressure between a first fluid at a first pressure and a second fluid at a second pressure. The rotor forms ducts that are routed from a first distal end to a second distal end. The pressure exchanger further includes a first end cover that forms a high pressure in (HPIN) port configured to provide the first fluid at the first pressure into the ducts. The first end cover forms a low pressure out (LPOUT) port configured to receive the first fluid from the ducts at a third pressure. One or more sidewalls of the first end cover that form the HPIN port or the LPOUT port are substantially planar. The pressure exchanger further includes a second end cover that forms a low pressure in (LPIN) port configured to provide the second fluid at the second pressure into the ducts and forms a high pressure out (HPOUT) port configured to receive the second fluid from the ducts at a fourth pressure.
