Recovery of fresh water from sea water

Claim 1

A METHOD OF RECOVERING FRESH WATER FROM SEA WATER CONTAINING SALTS TENDING TO CAUSE SCALE FORMATION AT ELEVATED TEMPERATURES ABOVE 170*F. WHICH COMPRISES, TREATING THE SEA WATER BY MIXING AN AMOUNT OF NON-PRECIPITATE FORMING ACID WITH SAID SEA WATER SUFFICIENT TO REDUCE SUBSTANTIALLY ITS TOTAL AMOUNT OF ALKALINITY EXPRESSED AS EQUIVALENT CALCIUM CARBONATE CONTENT TO AN AMOUNT RANGING UP TO ABOUT 30 P.P.M. WHEREIN DISSOLVED CO2 IS FORMED BY CHEMICAL REACTION AS DETERMINED BY TITRATION WITH A STANDARD ACID TO A METHYL ORANGE END-POINT AT SUBSTANTIALLY AMBIENT CONDITIONS PRIOR TO REMOVAL OF CO2, THEN REMOVING SUBSTANTIALLY THE CO2 FORMED, WHEREBY TO INHIBIT THE SCALE-FORMING TENDENCY AND THE CORROSIVE ACTION OF SAID ATREATED SEA WATER AT ELEVATED DISTILLATION TEMPERATURES RANGING UP TO ABOUT 25*F. AND HIGHER, AND SUBJECTING SAID TREATED SEA WATER TO DISTILLATION.
