Claim 12:
13. A system for vaporizing a feedstream containing dissolved solids therein, comprising:
at least one pump to pressurize a stream of liquid brine, wherein the stream of liquid brine comprises liquid brine combined with the feedstream, and the stream of liquid brine is below its saturation point;
at least one ohmic heating device, in fluid communication with the pump, to heat the pressurized stream of liquid brine, wherein:
the ohmic heating device comprises an outer tubular body functioning as a ground electrode, at least one inner tubular body functioning as a live electrode, and an annular space defined therebetween;
the pressurized stream of liquid brine is heated by flowing the pressurized stream of liquid brine through the annular space; and;
the ohmic heating device is operated under a temperature and pressure selected to prevent boiling of the pressurized stream of liquid brine as it flows through the ohmic heating device; and
the dissolved solids remain dissolved in the pressurized stream of liquid brine as the pressurized stream of liquid brine flows through the ohmic heating device; and
at least one vessel in fluid communication with the at least one ohmic heating device, the at least one vessel comprising a chamber having a liquid brine phase therein, wherein the at least one vessel comprises a flash inlet above the liquid brine phase to introduce the pressurized, heated stream of liquid into the chamber such that the pressurized, heated stream of liquid brine flashes to a vapor portion and a remaining liquid portion without flashing the liquid brine phase, wherein the remaining liquid portion enters the liquid brine phase.
