Abstract
A method of producing hydrogen chloride, or an aqueous solution thereof, includes the steps: a) furnishing a first electrolyte containing chloride ions; b) carrying out an electrodialysis, wherein the first electrolyte is subjected to a cathodic reduction resulting in a catholyte, wherein the concentration of chloride ions drops in the first electrolyte, the concentration of hydroxide ions increases in the first electrolyte, and a product in the form of hydrogen chloride or an aqueous solution thereof is produced; c) processing of at least a partial quantity of the catholyte, resulting in the first electrolyte, wherein an untreated saline water is used, the concentration of chloride ions increases in the catholyte and the concentration of hydroxide ions drops in the catholyte; and d) at least partial reuse of the catholyte processed according to step c) as the first electrolyte in step b).
