Based on using the alkaliferous brine from the diaphragm production system as the feed water for the ion-exchange membrane production system and enhancing the ratio of bittern doping,make full use of the alkaliferous brine produced by the evaporat.

Innovate electrolysis process by improving mixing proportion of bittern;

By optimizing the treatment process of bittern with ammonium,the ammonium content is reduced to the index demanded by caustic soda production,and the amount of nitrogen trichloride forming is decreased so that the safety of chlor-alkali production process is guaranteed,the doping level of bittern is raised and the production costs are reduced.

Comparison process of caustic soda production with mixing bittern and whole bittern;

The influence of adding brine ratio on the recovery rate of the potassium chloride in the KCl production process by adding brine method;
