METHOD OF LIMING SUGAR-CONTAINING SOLUTION Russian patent published in 2003 - IPC

Abstract RU 2205877 C1

FIELD: sugar production. SUBSTANCE: method consists in adding, to sugar-containing solution, catholite obtained when treating ammonium sulfate solution in cathodic chamber of diaphragm electrolyzer with undissolved electrodes until pH 8.9-10.1 and redox potential between -500 and -650 mV against silver chloride reference electrode ate attained. After addition of catholite, solution is completed with lime and agitated for 10 to 20 min at 60-80 C. Lime uptake for liming of pre-limed juice corresponds to 1.50-2.25% CaO based on the weight of beet. Lime uptake for liming of raw liquor corresponds to 2.70-4.05% CaO based on the weight of raw sugar. EFFECT: reduced lime uptake and improved purity of refined juice. 3 cl, 1 tbl, 4 ex
