Abstract
This invention relates to a new and novel brine system for use in electrolyzing salt to chlorine, caustic soda and hydrogen in chlor-alkali cells employing an ion exchange membrane and, more particularly, to the efficient use of brine as the raw material to be electrolyzed in chlor-alkali membrane cells. This invention also relates to a process for the conversion of a diaphragm cell and evaporator plant to one employing membrane type cells while still utilizing the existing brine treatment and caustic evaporation equipment and the resultant plant installations.
