Abstract
Systems and methods for reducing the pressure of a first pressurized fluid, thereby reducing the temperature of the pressurized fluid, and utilization of the reduced-pressure and temperature fluid to cool a second fluid. Such an approach can enable a reduction in the size and weight of a hydraulic system, utilize waste energy in a system, and/or minimize electrical power requirements of a system, among other benefits.
Claims20
A pumping system, comprising:
- a turbine mechanically coupled to a pump, the turbine having an outlet;
- and
- a heat exchanger fluidly coupled to the turbine downstream of the outlet and fluidly coupled to the pump, the heat exchanger configured to provide heat transfer between a working fluid exhausted from the turbine outlet and a liquid being pumped by the pump to cool the liquid being pumped.
A system, comprising:
- an expander for expanding a first fluid, the expander having an outlet;
- a pump or compressor for pressurizing a second fluid;
- and
- at least one heat exchanger, the at least one heat exchanger fluidly coupled to the expander downstream of the outlet and fluidly coupled to the pump or compressor for providing heat transfer between the first and second fluid.

A method of pressurizing a fluid, comprising:
- providing a pump or compressor for pressurizing the fluid;
- providing an expander;
- and
- placing the fluid in thermal communication with an exhaust from the expander to reduce a temperature of the fluid.
