Abstract

L'invention concerne un dispositif et un procédé de dessalement de solutions de NaCl utilisant une cellule électrochimique à trois chambres séparées par des membranes échangeuses d'ions correspondantes, à savoir une succession d'une chambre cathodique (16 ; 116), d'une membrane échangeuse de cations (28 ; 128), d'une chambre centrale (12 ; 112) pour la solution saline, d'une membrane échangeuse d'anions (26 ; 126) et d'une chambre anodique (14 ; 114). L'oxydation de OH- et la réduction de H3O+ avec formation de OH- et de H2 provoquent le passage des ions Na+ et Cl- de la chambre centrale vers les autres chambres, réduisant ainsi la concentration en sel. L'alimentation de la chambre cathodique peut être gérée dans un circuit avec l'insertion d'un réacteur de carbonatation (50) pour réduire la concentration de NaOH et éliminer le CO2 de l'air. Dans certaines conditions, les chlorures entrant dans la chambre anodique subissent une oxydation et le chlore qui y est formé réagit avec l'eau pour produire du HCl et du HClO.
