Optimization of the process parameters of an electrochemical cell in the IS process

Nomura, Mikihiro*; Okuda, Hiroyuki; Kasahara, Seiji ; Nakao, Shinichi*

The Bunsen reaction (SO $_{2}$ +I $_{2}$ +2H $_{2}$ O=H $_{2}$ SO $_{4}$ +2HI) in the water-splitting IS process was examined using an electrochemical cell with a cation exchange membrane. The optimal molalities of anolyte and catholyte were evaluated by total thermal efficiency. The I $_{2}$ /HI ratio had little effect on the required total voltage; the I $_{2}$ /HI ratio can be reduced to 0.5 without decreasing the efficiency. HI and H $_{2}$ SO $_{4}$ molality greatly affected the efficiency. Membrane resistances are very important parameters affecting the efficiency. The total thermal efficiency increased by 3.0% by increasing the operating temperature from 313K to 363K.
