Abstract
La presente invenzione riguarda un metodo di produzione di soda caustica mediante elettrolisi di sale sodico secondo le realizzazioni preferite :a) uso di sale sodico di un acido volatile, preferibilmente carbonato o bicarbonato e sodico o loro miscele da addizionare ad un sistema di riciclo anodico contenente una soluzione di sale sodico di un acido diverso dagli acidi alogenidrici, preferibilmente solfato sodico b) uso di carbonato di calcio e di sale sodico di un acido diverso dagli acidi alogenidrici, preferibilmente solfato sodico, da addizionare ad un sistema di riciclo anodico contenente una soluzione di detto sale sodico, con formazione di una sospensione di solfato di calcio che viene estratta dal sistema c) uso di idrogeno da alimentare all'anodo con formazione di acidità non accompagnata da sviluppo di ossigeno o di altri sottoprodotti.
