摘要： CALCIUM AND SODIUM CHLORIDES ARE PRODUCED BY EVAPORATING THE DISTILLATION LIQUID RESULTING FROM THE AMMONIA SODA ASH PRODUCTION PROCESS. THIS LIQUID IS CLARIFIED AND INTRODUCED INTO THE EVAPORATORS TO MIX WITH A CONCENTRATED CALIUM CHLORIDE SOLUTION CONTAINED THEREIN, THE CONCENTRATION OF CALCIUM CHLORIDE IN SUCH A MIXED SOLUTION BEING MAINTAINED AT 28-45 WT. PERCENT. IN THE PROCESS ACCORDING TO THE METHOD DISCLOSED HEREIN, STEAM IS PASSED CONSECUTIVELY THROUGH ALL THE EVAPORATORS OF THE PLANT.

THE APPLICATION OF THE PROPOSED METHOD PRACTICALLY PRECLUDES THE FORMATION OF GYPSUM DEPOSITS ON THE HEATING SURFACES OF THE EVAPORATORS.
