| titleOfInvention | Purification of chlor-alkali membrane cell brine |
| abstract | This invention relates to methods and systems for purifying brine for electrolysis in chlor-alkali cells, especially membrane cells by reducing the sulfate ion concentration, while at the same time minimizing the concentration of other undesireable ions such as calcium and chlorate. The methods and systems employed are unique combinations of refrigeration and crystalization, and brine recirculation techniques in the systems for electrolyzing brine. |
