Title (EN) METHODS AND SYSTEMS FOR PRODUCTION OF CHLORINE AND CAUSTIC USING OXYGEN DEPOLARIZED CATHODE
(FR) PROCÉDÉS ET SYSTÈMES DE PRODUCTION DE CHLORE ET DE SOUDE CAUSTIQUE AU MOYEN D'UNE CATHODE DÉPOLARISÉE À L'OXYGÈNE
Abstract: front page image
(EN)Methods and systems for the production of chlorine and caustic employ a hydroxide-stable anion exchange membrane located against the face of the oxygen depolarized cathode (ODC). The anion exchange membrane contains a polymer including one or more of a phosphonium, a primary, secondary, tertiary or quaternary ammonium, a guanidinium, or a positively charged cyclic amine.
(FR)Cette invention concerne des procédés et des systèmes de production de chlore et de soude caustique qui mettent en œuvre une membrane échangeuse d'anions stable à l'hydroxyde disposée contre la face de la cathode dépolarisée à l'oxygène (ODC) La membrane échangeuse d'anions contient un polymère comprenant un ou plusieurs éléments parmi un phosphonium, un ammonium primaire, secondaire, tertiaire ou quaternaire, un guanidinium ou une amine cyclique chargée positivement.
