Electrochemical industries consume approximately 7% of all the electric power produced in the United States, and the production of chlorine and caustic soda by the chlor-alkali industry accounts for roughly 20% of this energy consumption. The most advanced chlor-alkali technology utilizes a cation exchange membrane electrolysis cell to produce chlorine, by-product hydrogen, and 30 wt % NaOH. Prior to commercial sale, the caustic soda is concentrated to 50 wt % by evaporation. The by-product hydrogen is currently used for its thermal value in the caustic concentration process or is sold commercially.
