РАСЧЕТ ИОНООБМЕННОЙ КОЛОННЫ ДЛЯ ОЧИСТКИ РАСТВОРА ГИДРОКСИДА ЛИТИЯ ОТ АНИОНОВ ХЛОРА
Аннотация
Рассмотрена возможность доочистки водного раствора LiOH от анионов хлора после электролиза. При анализе существующих методов очистки предложено использовать очистку гидроксида лития в ионообменной колонне. Составлена математическая модель и алгоритм расчета ионообменной колонны с неподвижным и движущимся слоем анионита АВ-17-08 в ОН-форме. Получены зависимости основных параметров: времени рабочего цикла, степени использования обменной емкости ионита и удельного объема очищаемого раствора на 1кг ионита для стандартной колонны. Получены и проанализированы графики зависимости концентрации анионов хлора в ионите от высоты его слоя в очищаемом растворе в середине и в конце времени рабочего цикла. Даются рекомендации по предотвращению истирания гранул ионита во время эксплуатации ионообменных колонн.
