Abstract

L'invention concerne un dispositif interne de séparation de gaz pour une cellule 10 d'électrolyse comportant une électrode dégageant du gaz et fonctionnant à une densité totale du courant supérieure à 269 A/dm**2 de surface horizontale interne de la cellule. Le dispositif comprend au moins un collecteur 70 de gaz à l'intérieur des doigts 54 de l'anode et un organe 30 de dégagement ayant moins de 1,21 dm**2 de section horizontale interne par kA de courant total de la cellule. Application dans une cellule d'électrolyse d'une saumure d'halogénure alcalin, briser la mousse pour éviter son entraînement dans l'halogène gazeux 24 et/ou l'hydroxyde alcalin produits.
