Abstract

Patente de Invenção: <B>"PROCESSO PARA A REMOçãO DE ìONS DE SULFATO DE UM ELETRóLITO"<D> Um processo para a remoção de íons de sulfato de um eletrólito de um sistema de oxidação - redução eletroquímica onde o dito eletrólito compreende um halogênio e no qual os íons de sulfato são um contaminante ou interferente, cujo processo compreende as etapas de: (i) aumento da concentração de haleto no eletrólito por redução eletroquímica do halogênio, (ii) cristalização de um sal sulfato fora do eletrólito, e (iii) separação do eletrólito do sal sulfato cristalizado. Um processo eletroquímico para estocagem de energia e/ou liberação de força compreendendo a etapa de remoção de íons de sulfato do eletrólito de acordo com o processo citado acima é também mostrado.
