A PROCESS FOR EVOLVING VAPOR FROM SEA WATER WITHIN A VAPORIZATION CHAMBER TO PREVENT FORMATION OF SCALE ON THE HEAT EXCHANGE SURFACES THEREOF COMPRISING THE STEPS OF FEEDING SEA WATER TO THE LOWER LIQUID REGION OF THE VAPORIZATION CHAMBER, THE LIQUID REGION OF THE VAPORIZATION CHAMBER CONTAINING A LIQUID DOWNTAKE PASSAGE AND A PLURALITY OF HEAT EXCHANGE SURFACES DEFINING FLOW PASSAGES, REGULATING THE TEMPERATURE OF THE HEAT EXCHANGE SURFACES TO BE WITHIN THE RANGE OF FROM 95*F. TO 120* F., MAINTAINING A PRESSURE WITHIN THE VAPOR REGION OF THE VAPORIZATION CHAMBER SUFFICIENTLY LOW TO EVOLVE VAPOR FROM THE LIQUID WITHIN THE LIQUID REGION, CIRCULATING THE SEA WATER FROM THE LIQUID DOWNTAKE PASSGE THROUGH THE FLOW PASSAGES AND BACK TO THE DOWNTAKE PASSAGE AT A VELOCITY AND PRESSURE SUFFICIENT TO PREVENT VAPOR FROM BEING EVOLVED IN THE FLOW PASSAGES, AND REMOVING CONCENTRATED SEA WATER FROM THE LIQUID REGION OF THE VAPORIZATION CHAMBER SO AS TO MAINTAIN A CONCENTRATION RATIO WITHIN THE RANGE OF FROM 1.2 TO 1.5 BUT NOT EXCEEDING THE CONCENTRATION RATIO REPRESENTED BY THE CURV E OF FIGURE 4 FOR THE TEMPERATURE AT WHICH THE HEAT EXCHANGE SURFACES ARE MAINTAINED.
