ABSTRACT:
Heat energy is more efficiently recovered from geothermal brines by preflashing the brine to remove dissolved, non-condensible gases before flashing the brine to produce motive steam. Power requirements for removal of non-condensibles from turbine exhausts (in order to maintain adequately low exhaust pressures) are obviated. The heat content of the pre-flashed vapors may be largely utilized for superheating and reheating the motive steam.
