ABSTRACT:
A method for producing mechanical energy from geothermal fluids in which a heat transfer fluid (HTF) is heated by direct contact with the hot geothermal fluids, thereby partially cooling the geothermal fluids. A working fluid is heated by direct contact with the partially cooled geothermal fluid and is heated further by indirect heat exchange with the hot HTF. The heated working fluid is utilized in a heat engine for the production of mechanical energy.
