Abstract

Procedimiento para la elaboración electroquímica de HCl gaseoso para dar cloro de gran pureza, caracterizado porque se hace reaccionar el HCl gaseoso, en una primera etapa de electrolisis en fase gaseosa (1), para dar un cloro gaseoso que contiene HCl gaseoso, el cloro gaseoso, que contiene HCl se extrae por lavado en una etapa de absorción (2) con ácido clorhídrico líquido empobrecido con formación de ácido clorhídrico enriquecido y de este modo se libera el cloro gaseoso del HCl gaseoso, el ácido clorhídrico enriquecido se descompone, en una etapa de electrolisis en fase líquida (5), con formación de ácido clorhídrico empobrecido, en cloro gaseoso el ácido clorhídrico empobrecido se recicla (3,4) hasta la etapa de absorción (2) y las corrientes de cloro, generadas en la etapa de electrolisis en fase gaseosa (1) y en la etapa de electrolisis en fase líquida (5) se retiran y, en caso dado, se combinan y en caso dado se secan.
