Abstract
An improved process and apparatus for pH control and energy savings in chlor-alkali electrolysis cells is disclosed wherein a fuel cell type spaced porous catalytic anode is utilized to chemically oxidize a controlled, sub stoichiometric amount of hydrogen to provide hydrogen ions to a recirculating anolyte. The pH is monitored and the flow of hydrogen fuel adjusted to provide a resultant desired pH in the range of about 2 to about 4. Optionally, hydrogen gas produced at the cell cathode may comprise the fuel supply and a spaced porous catalytic cathode may be employed for hydrogen supply control and depolarization.
