Abstract
Useful energy is derived from steam flashed from hot geothermal brine having a tendency to deposit amorphous silica or calcite upon a reduction in the pressure or temperature of the brine. Steam condensate produced from the flashed steam is pressurized, acidified and preheated, and the acidified preheated steam condensate is mixed with the hot geothermal brine at a point upstream of the flash stage so as to form a hot aqueous mixture with a reduced tendency for deposition of amorphous silica or calcite.
