Pressure and temperature recovery systems for geothermal power plants

A method of operating a geothermal power system, comprising:

• flowing a first fluid into a first inlet of a pressure exchanger;
• reducing a pressure of the first fluid in the pressure exchanger as the first fluid transits from the first inlet of the pressure exchanger to a first outlet of the pressure exchanger;
• increasing a pressure of a second fluid in the pressure exchanger as the second fluid transits from a second inlet of the pressure exchanger to a second outlet of the pressure exchanger, the second fluid having a first temperature at the second outlet;
• flowing the second fluid through a turbine coupled to a generator, wherein the second fluid enters the turbine at a second temperature substantially equal to the first temperature;
• generating electricity using the generator;
• and
• flowing the second fluid from the turbine to the second inlet of the pressure exchanger, wherein the second fluid exits the turbine at a third temperature, and enters the second inlet of the pressure exchanger at a fourth temperature substantially equal to the third temperature.

A geothermal power system, comprising:

• a heat exchanger fluidically coupled to a first pressure exchanger, wherein:
• a first fluid enters the first pressure exchanger at a first inlet, and transits through the first pressure exchanger in a first fluid path from the first inlet to a first outlet;
• the heat exchanger receives the first fluid from the first outlet of the first pressure exchanger;
• the first pressure exchanger receives the first fluid from the heat exchanger at a second inlet of the pressure exchanger;
• and
• the first fluid transits through the first pressure exchanger in a second fluid path from the second inlet to a second outlet, the second fluid path separate from the first fluid path.
