Переработка дистиллерной жидкости с получением товарных продуктов

Переработка дистиллерной жидкости с получением товарных продуктов

Abstract

Исследован процесс переработки отхода производства кальцинированной соды – дистиллерной жидкости с получением гидроксида кальция, гидроксида натрия и соляной кислоты. Процесс состоял из двух стадий. На первой стадии дистиллерная жидкость обрабатывалась гидроксидом натрия до максимального перевода кальция в нерастворимую форму – гидроксид кальция. На второй стадии полученный фильтрат, состоящий в основном из хлорида натрия, подвергался обработке в трехкамерном мембранном электролизере. Для разграничений камер электролизера использовали катионообменную и анионообменную мембраны марки МК-40 и МА-40 соответственно. Электрохимический процесс изучали при плотностях тока 32,2; 63,4 и 97,6 мА/см2. При дальнейшем увеличении плотности тока происходит сильный разогрев растворов в аппарате. Изучены основные закономерности процесса переработки дистиллерной жидкости по указанной методике. Показано, что технологический процесс можно организовать без использования химических реагентов.

It was studied the treatment of wastes of soda ash – distiller fluid with obtaining of calcium hydroxide, sodium hydroxide and hydrochloric acid. The process consisted of two stages. In the first stage of distilled liquid was treated by sodium hydroxide to convert calcium into the maximal insoluble form – calcium hydroxide. In the second stage of filtrate, consisting mainly from sodium chloride, was treated in a three-chambered membrane electrolyzer. For camera cells partition of electrolyzer are used cation-ecxhange and anion-exchange membranes type MK-40 and MA-40, respectively. Electrochemical process was studied at current densities of 32,2; 63,4 and 97,6 mA/cm2. Further increase in current density leads to the high heating of solution in the apparatus. Main regularities of distiller fluid treatment upon mentioned methodic are studied. It was shown, that a technological process may be realized without chemical reagents.
