Method and apparatus for treating salts

Claim 1

A METHOD OF TREATING SOLID IMPURE SODIUM CHLORIDE WHICH COMPRISE INCORPORATING SOLID IMPURE SODIUM CHLORIDE IN AN AQUEOUS SOLUTION OF SODIUM CHLORIDE IN A SALT MIXING ZONE, DIRECTING SAID SOULATION CONTAINING SAID SOLID IMPURE SODIUM CHLORIDE FROM SAID SALT MIXING ZONE TO IMPURE SODIUM CHLORIDE INCORPORATED THEREIN TO A TEMPERTURE AF AT LEAST ABOUT 210* F. WITH ATTENDANT ADDITION THERETO OF CONDENSATE RESULTING FROM THE CINDENSATION OF SAID STEAM, CONTAININGCONTACT BETWEEN SAID SOLID HEATING ZONE THEREBY HEATING SAID SOLUTION IN A DISSOULTION ZONE WITH PRODUCTION OF A SOULATION SUBSTANCIALLY SATURATED WITH SODIUM CHLORIDE, SEPARATING THE RESULTING SUBSTANTIALLY SATURATED SOLUTION FROM ANY SOLID MATERIAL CONTAINED THERIN IN A CLARIYING ZONE BY FILTERING WHILE SAID SOULATION AS AT SAID TEMPERATURE OF AT LEAST ABOUT 210* F. TO PRODUCE A CLARFIED SOULATION, DIRECTING THE CLARIFIED SOULATION INTO A SOULATION MIXING ZONE, CIRCULATING SODIUM CHLORIDE SOULATION FROM SAID SOULATING MIXING ZONE TO AN EVEPORATION ZONAE MAINTAINED AT A PRESSURE SUBSTANTIALLY LOWER THAN THE PREVAILING IN SAID SOULATION MIXING ZONE AND BACK TO SAID SOLUTION MIXING ZONE, BOILING SAID SOLUTION IN SAID EVAPORATION ZONE WITH SEPERATION OF VAPOR THEREFROM AND LOWERING OF THE TEMPERATURE THEREOF AND WITH SIMULTANEOUS PRODUCTION OF CRYSTALLIZE SODIUM CHLO RIDE IN SAID EVEPORATION ZONE, WITHDRAWING RESIDUAL SOULTION AND CRYSTALLIZED SODIUM CHLORIDE CONTAINED THERIN

Claim 2

A METHOD OF TREATING SOLID IMPURE SODIUM CHLORIDE WHICH COMPRISE INCORPORATING SOLID IMPURE SODIUM CHLORIDE IN AN AQUEOUS SOLUTION OF SODIUM CHLORIDE IN A SALT MIXING ZONE, DIRECTING SAID SOULATION CONTAINING SAID SOLID IMPURE SODIUM CHLORIDE FROM SAID SALT MIXING ZONE TO IMPURE SODIUM CHLORIDE INCORPORATED THEREIN TO A TEMPERTURE AF AT LEAST ABOUT 210* F. WITH ATTENDANT ADDITION THERETO OF CONDENSATE RESULTING FROM THE CINDENSATION OF SAID STEAM, CONTAININGCONTACT BETWEEN SAID SOLID HEATING ZONE THEREBY HEATING SAID SOLUTION IN A DISSOULTION ZONE WITH PRODUCTION OF A SOULATION SUBSTANCIALLY SATURATED WITH SODIUM CHLORIDE, SEPARATING THE RESULTING SUBSTANTIALLY SATURATED SOLUTION FROM ANY SOLID MATERIAL CONTAINED THERIN IN A CLARIYING ZONE BY FILTERING WHILE SAID SOULATION AS AT SAID TEMPERATURE OF AT LEAST ABOUT 210* F. TO PRODUCE A CLARFIED SOULATION, DIRECTING THE CLARIFIED SOULATION INTO A SOULATION MIXING ZONE, CIRCULATING SODIUM CHLORIDE SOULATION FROM SAID SOULATING MIXING ZONE TO AN EVEPORATION ZONAE MAINTAINED AT A PRESSURE SUBSTANTIALLY LOWER THAN THE PREVAILING IN SAID SOULATION MIXING ZONE AND BACK TO SAID SOLUTION MIXING ZONE, BOILING SAID SOLUTION IN SAID EVAPORATION ZONE WITH SEPERATION OF VAPOR THEREFROM AND LOWERING OF THE TEMPERATURE THEREOF AND WITH SIMULTANEOUS PRODUCTION OF CRYSTALLIZE SODIUM CHLO RIDE IN SAID EVEPORATION ZONE, WITHDRAWING RESIDUAL SOULTION AND CRYSTALLIZED SODIUM CHLORIDE CONTAINED THERIN
