METHOD FOR CRYSTALLIZATION OF SODIUM SULFATE FORM GAS TREATMENT SOLUTION ORIGINATING FROM ELECTROLYTIC ALUMINUM PRODUCTION Russian patent published in 2003 - IPC

Abstract RU 2215689 C2

FIELD: nonferrous metallurgy. SUBSTANCE: cooling-assisted crystallization is characterized by that, during autumn-winter period, cooling of sodium sulfate solution is accomplished by cold atmospheric air: first in outdoor pipelines in recirculation mode and then in crystallizers. EFFECT: enhanced productivity of process and reduced power consumption due to disabled cooling systems. 1 tbl
