ABSTRACT:
An improved method and apparatus for disposal of spent brine after the energy and mineral values have been extracted from the brine, taking advantage of the basic thermodynamic properties of suspended and dissolved scalars in geothermal fluids. A controlled portion of the extracted steam energy value from the brine is used to reheat spent brine before reinjection. The spent brine thereby ceases to be supersaturated with respect to solids, and stabilized silicas therein do not precipitate out and deposit themselves upon the entrance of a reinjection well. Means for using a controlled portion of the extracted steam energy from a plurality of serially connected flasher reactors is shown.
