Abstract

Patente de Invenção: <B>''ELETROLISADOR BIPOLAR DE MEMBRANA DE TROCA IÈNICA''<D>. A presente invenção descreve um projeto de elementos para eletrolisadores de troca iónica para a eletrólise de salmoura para produzir cloro, hidrogênio e soda cáustica. Este novo projeto resolve os problemas que afetam a técnica anterior, tanto ao minimizar a concentração de eletrólito e gradientes de temperatura, quanto à flutuação de pressão que recorre a componentes que são fáceis de ser instalados e podem ser obtidos através de ciclos de produção automatizada.
