Patent ID: 8371122

Claim:
A geothermal power generation system, comprising: a geothermal fluid source capable of producing a fluid comprising steam and at least one non-condensable gas; a first separator in fluid communication with the geothermal fluid source, the first separator having a high pressure steam outlet and a liquid fraction outlet, the first separator being capable of producing from the fluid a high pressure steam outflow through the high pressure steam outlet and a liquid fraction outflow through the liquid fraction outlet; a high pressure turbine in fluid communication with the high pressure steam outlet, the high pressure turbine being coupled to a first power generator; a high pressure condenser in fluid communication with the high pressure turbine, the high pressure condenser being capable of condensing steam to form a condensate, separating the at least one non-condensable gas from the condensate and venting the non-condensable gas through an NCG outlet; a low pressure separator in fluid communication with the liquid fraction outlet of the first separator, the low pressure separator being capable of separating steam from the liquid fraction outflow and providing low pressure steam through a low pressure steam conduit; a low pressure turbine in fluid communication with the low pressure steam conduit, the low pressure turbine being coupled to a second power generator; a main condenser in fluid communication with the low pressure turbine; a second low pressure separator; and a flash valve in fluid communication with both the second low pressure separator and the high pressure condenser in a manner that allows condensate to flow from the high pressure condenser through the flash valve to form low pressure steam and a liquid fraction, the steam being separated from the liquid fraction using the second low pressure separator.
