Abstract
L'invention concerne un appareil et un procédé pour la génération sur site de quantités relativement petites d'un gaz halogène, de préférence du chlore. L'appareil comprend au moins une cellule électrolytique présentant une section anolyte et une section catholyte. L'une d'entre elles au moins est connectée, par des conduits pour fluide, à un élément chauffant de fluide qui chauffe une solution électrolyte avant qu'elle ne pénètre dans la section. La chaleur facilite aussi la circulation de la solution électrolyte à travers l'appareil en raison de l'effet de thermosiphon. L'élément chauffant est, à son tour, connecté à un organe de réapprovisionnement en électrolyte. L'appareil comprend au moins un séparateur de gaz qui sépare le gaz généré dans la cellule électrolytique de la solution sans nécessiter de réservoir pour stocker la solution.
