Abstract

Processo di elettrolisi cloro-soda con celle a diaframma comprendenti catodi ed anodi intercalati e provvisti di superfici con aperture, detti catodi essendo rivestiti con diaframmi porosi, almeno parte di detti anodi provvisti con dispositivi idrodinamici atti a promuovere la circolazione interna caratterizzato dal fatto che il contenuto di ossigeno nel cloro e di clorati nella soda caustica prodotta viene controllato indipendentemente dalla portata della salamoia fresca e dalla concentrazione della soda caustica stessa mediante l'addizione di acido cloridrico all'anolita attraverso almeno un condotto distributore posizionato al di sopra di detti dispositivi idrodinamici.
