Abstract:
1. An organic Rankine cycle (ORC) system for generating electrical power using a sub-sea geothermal source from a sea, the ORC system comprising: a first pressure vessel containing an evaporator configured to receive heat from the sub-sea geothermal source and vaporize an organic fluid passing through the first pressure vessel; a second pressure vessel removably connected to the first pressure vessel and containing a turbine configured to receive the organic fluid and expand the fluid to produce mechanical shaft energy convertible to electrical power; a third pressure vessel removably connected to the second pressure vessel and containing a condenser configured to condense the vaporized organic fluid flowing from the second pressure vessel and reject heat to cold sea water; and a fourth pressure vessel removably connected to the third pressure vessel and the first pressure vessel, and containing a pump configured to increase a pressure of the condensed organic fluid and recycle the organic fluid to the first pressure vessel.
