Evaporative salt plant.
0 This invention relates to an evaporative salt plant
design including methods of operation and apparatus
which produce high purity salt economically and in
high yield comprising the combination of a gas turbine which drives a vapor compressor, whose exhaust gases are used to produce steam to drive a
topping steam turbine generator, which in turn generates the electrical energy requirements of the
plant, and wherein the discharge vapors from the
steam turbine are combined with the discharge vapors from the vapor compressor, which is in turn in
combintion with a vapor compression evaporator and
a purge evaporator, whereby both evaporators produce salt, and where the overhead vapors of the
purge evaporator are used in a brine cooled condenser to preheat input cold brine, thereby producing water condensate which is recovered, along with
evaporator steam chest condensate streams, and
used in solution mining underground salt, thereby
allowing for both the productive use and recovery of
substantially all the raw material and energy inputs
to the plant, and the friendly environmental operation
of the plant.
