| titleOfInvention | Electrolysis method of alkali metal chloride |
| abstract | In an alkaline metal chloride electrolysis method including a saturated brine preparation process, an electrolysis process, a chlorine deaeration process, and a chlorine adsorption removal process using activated carbon, the growth of halophilic bacteria is prevented in the chlorine adsorption removal process. An improved alkali metal chloride electrolysis method is provided. SOLUTION: A water supply means is provided in the chlorine adsorption removal step to reduce the salt concentration of water that contacts the activated carbon in the chlorine adsorption removal step. In a preferred embodiment of the present invention, after the chlorine adsorption 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 |
