| titleOfInvention | Electrolysis method of alkali metal chloride |
| abstract | The present invention relates to an alkaline metal chloride electrolysis method including a saturated brine preparation process, an electrolysis process, a chlorine deaeration process, and a chlorine decomposition removal process using a reducing agent, and effective use of the reducing agent used in the chlorine decomposition removal process. An improved alkali metal chloride electrolysis method is provided. An oxygen deaeration process is provided between a chlorine deaeration process and a chlorine decomposition removal process. In a preferred embodiment of the present invention, after the chlorination removal step, as a degassing step, light brine and water are alternately passed through a separation column packed with an ion exchanger, and mainly contain alkali metal chloride. The effluent and the effluent containing sulfate are separated and recovered, and the former is circulated to the saturated brine preparation step, and the latter is removed from the circulation system. [Selection figure] None |
