Abstract

CÉLULA ELETROLÍTICA E EQUIPAMENTO ELETROLISADOR. A presente invenção refere-se a uma célula eletrolítica, particularmente idealizada para a obtenção de soda cáustica (NaOH) e halogênios por eletrólise, dotada de pelo menos um primeiro terminal elétrico e pelo menos um segundo terminal elétrico adjacentemente posicionados para a realização de eletrólise, caracterizada pelo fato de que o primeiro terminal elétrico é um ânodo é centralmente posicionado na célula eletrolítica constituindo uma câmara anódica e o segundo terminal elétrico compreende dois cátodos, cada qual posicionado lateralmente em relação ao ânodo e opostamente entre si e constituindo uma respectiva câmara catódica, o ânodo e cada cátodo sendo separados por meio de pelo menos uma membrana semipermeável.ELECTROLYTIC CELL AND ELECTROLYZER EQUIPMENT. The present invention relates to an electrolytic cell, particularly ideal for obtaining caustic soda (NaOH) and halogens by electrolysis, having at least one first electrical terminal and at least one second electrical terminal adjacent for electrolysis, characterized by the fact that the first electrical terminal is an anode is centrally positioned in the electrolytic cell constituting an anodic chamber and the second electrical terminal comprises two cathodes, each positioned laterally in relation to the anode and opposite each other and constituting a respective cathodic chamber, the anode and each cathode being separated by at least one semipermeable membrane.
