Abstract

Procedimiento y dispositivo para la obtención de cloro e hidrógeno a partir de ácido clorhídrico por electrolísis en una célula de electrolísis compuesta de un número múltiple de electrodos bipolares dispuestos verticalmente, habiéndose colocado entre cada vez dos electrodos, un diafragma para subdividir las cámaras de electrolísis formadas entre éstos, en un recinto de anolito y en un recinto de catolito, además, disposiciones de salida y de alimentación para los electrolitos, cuyo procedimiento se caracteriza porque el ácido clorhidrico se electroliza en como mínimo dos etapas consecutivas desgasificándose éste después de salir de una primera etapa y antes de entrar en la siguiente etapa a continuación.
