Patent ID: 6912853

Claim:
A method for increasing the output of a geothermal steam turbine power plant operating on geothermal steam separated by a main high-pressure flash separator from high pressure geothermal fluid, said method comprising the steps of: (i) supplying all the geothermal steam produced by the main high-pressure flash separator to a high-pressure geothermal steam turbine, from which exits expanded geothermal steam; (ii) providing a separate, additional flash separator that receives high pressure geothermal fluid and produces steam for operating a non-condensable gas ejector for ejecting non-condensable gases separated from said expanded geothermal steam; and (iii) whereby said high-pressure geothermal fluid is supplied to both said main high-pressure flash separator and said separate, additional flash separator from the same production well in a pumped geothermal system.
