METHOD FOR PRODUCING SALTS WITH A REDUCED WATER OF CRYSTALLISATION CONTENT Russian patent published in 2018 - IPC F26B3/06 F26B3/20 F26B21/04 F26B21/08 

Abstract RU 2655442 C2

FIELD: drying.

SUBSTANCE: present invention relates to a method for drying salts with a water of crystallisation content in convective apparatuses that can additionally be indirectly heated. Method for drying salts with a water of crystallisation content in convective apparatuses comprises drying above a specified moisture content in the drying gas, for example the absolute humidity greater than 10%, wherein the moisture content of the drying gas is set at a level higher than the predetermined humidity value solely due to evaporated water. Another embodiment of the method for drying salts is characterized in that the moisture content in the drying gas is adjusted above specified humidity value by complete recirculation of the drying gas, wherein the evaporated water from the circulation is discharged by condensation and the moisture content of the drying gas is adjusted by means of the temperature condenser.

EFFECT: invention should provide for the production of salts with a reduced content of water of crystallisation.
