Abstract

Sodium chlorate (NaClO3) is produced from two undivided electrolysis cells, where the oxidation reaction of sodium chloride (NaCl) to chlorine occurs on the anode side, and the reduction of water (H2O) to hydrogen occurs on the cathode side. In the process production, requires considerable electrical energy which reaches 5.05 MWh per ton of sodium chlorate. With an average energy efficiency of 95% on an industrial scale, improvements are still needed to increase energy efficiency and prevent excessive energy consumption. This study aims to optimize process conditions of electrolyzer (e.g. flowrate, voltage, and current), hence maintaining the electrolyzer performance and running well as long as possible. The results showed that the voltage and resistance of the electrolyzer increase over the time and electrical energy consumption per ton of sodium chlorate will increase too. Interestingly, increasing production capacity (up to 58.24%) will increase the flowrate and electric current in the electrolyzer and will reduce the resistance value (up to 31.25%). Performing an acid wash process in a certain period on the electrolyzer is useful to keep the voltage value from continuing to increase. These two processes will reduce the total electrical energy consumption and prevent excessive energy consumption by continues process production.
