Abstract
A device may receive heat from a production fluid with a source heat exchanger. A device may transfer the heat to a working fluid with the source heat exchanger. A device may expand the working fluid in a turbine. A device may generate electricity with the turbine. A device may exhaust heat from the working fluid to an ambient liquid with a sink heat exchanger. A device may compress the working fluid after the sink heat exchanger and before the source heat exchanger.
Claims20
A method of producing electricity, the method comprising:
- receiving heat from a production fluid with a source heat exchanger;
- transferring the heat to a working fluid with the source heat exchanger;
- expanding the working fluid in a turbine;
- generating electricity with the turbine;
- exhausting heat from the working fluid to an ambient liquid with a sink heat exchanger, wherein the sink heat exchanger is radially offset from the source heat exchanger, and insulation is positioned between the source heat exchanger and the sink heat exchanger;
- and
- compressing the working fluid after the sink heat exchanger and before the source heat exchanger.
A system for producing electricity, the system comprising:
- a working fluid conduit configured to flow a working fluid therethrough;
- a source heat exchanger in thermal communication with the working fluid conduit and configured to transfer heat from a production fluid to the working fluid conduit;
- a sink heat exchanger in thermal communication with the working fluid conduit and configured to exhaust heat from the working fluid conduit to an ambient liquid;
- insulation positioned between the source heat exchanger and the sink heat exchanger;
- and
- a turbine in fluid communication with the working fluid conduit and configured to generate electricity from a flow of working fluid therethrough.
