Abstract
A process is disclosed for producing chlorine and caustic soda in an electrolytic membrane cell which comprises providing a pressure differential between the anode compartment and the cathode compartment sufficient to prevent substantial contact of the membrane with the anode, and reducing fluctuations in the pressure differential by allowing depleted sodium chloride brine and chlorine gas to flow freely from the anode compartment to a brine collection point. Also, the caustic soda and hydrogen gas produced in the cathode compartment are allowed to flow freely from the cathode compartment to a caustic soda collection point.
