Abstract
An improved process for the electrolysis of an aqueous electrolyte in an electrolytic membrane cell is provided. The membrane cell is comprised of an anode compartment having at least one anode and containing the aqueous electrolyte and a cathode compartment containing at least one cathode and a concentrated catholyte liquor. A vertically positioned cation exchange membrane separates the anode compartment from the cathode compartment. The process improvement comprises exposing a substantial portion of the cathode to a gaseous atmosphere, this substantial portion of the cathode is not immersed in the concentrated catholyte liquor produced. The concentrated aqueous catholyte liquor is removed from the cathode compartment to prevent a substantial accumulation of catholyte liquor in the cathode compartment. The improved process can be carried out in a novel electrolytic cell in which the cathode compartment is substantially reduced in size to permit a material savings as well as provide a higher production capacity per unit of floor space.
