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. |
