Abstract

Procedimiento de electrólisis de salmuera de cloruro sódico, en el cual procedimiento a) se introduce salmuera acuosa en el compartimiento de ánodo de una célula electrolítica, b) se introduce agua o hidróxido sódico acuoso en el compartimiento de cátodo de la célula, c) estando dichos compartimientos separados por una membrana catiónica perselectiva, d) se extraen cloro y salmuera agotada a través de una primera conducción común desde el compartimiento de ánodo hasta el punto de recogida de la salmuera y e) se extraen disolución de hidróxido sódico e hidrógeno a través de una segunda conducción común desde el compartimiento de cátodo hasta un punto de recogida de disolución de hidróxido sódico, caracterizado porque se provee una diferencia de presión entre el compartimiento de ánodo y el compartimiento de cátodo, suficiente para impedir un contacto substancial entre la membrana y el ánodo y para reducir las fluctuaciones de dicha diferencia de presión, por medio del mantenimiento de circulación libre e ininterrumpida de cloro y salmuera agotada a través de dicha primera conducción.
