  • Method for rejuvenating chlor-alkali cells
    Patent number: 4204921
    Abstract: Deposits of alkali metal ions such as calcium and magnesium on chlor-alkali cathodes and diaphragms are removed by feeding an acid such as hydrochloric acid into the cathode feed in an amount sufficient to reduce the pH below 8 for a time sufficient to remove these deposits and restore the cell to normal operation. The use of this invention allows one to use relatively high hardness water as the cathode feed solution during normal operation of a membrane chlor-alkali cell.
