Abstract

EL INVENTO SE REFIERE A UN DISPOSITIVO PARA REALIZAR EL PROCEDIMIENTO DE ELECTROLIZAR POR MEMBRANAS Y EN VARIAS ETAPAS, SOLUCIONES ACUOSAS CONTENIENDO SULFATOS ALCALINOS, EL DISPOSITIVO CONSTA DE UNA SERIE DE CELULAS ELECTROLITICAS PRESENTANDO TRES CAMARAS QUE TRABAJAN EN SERIE; SE DISTRIBUYEN EN ANODO, CAMARA CENTRAL Y CATODO Y ESTAN SEPARADAS UNAS DE OTRAS POR MEMBRANAS INTERCAMBIADORAS DE IONES. EL PROCEDIMIENTO SE CARACTERIZA PORQUE: SE CONDUCE LA SOLUCION ACUOSA QUE CONTIENE SULFATO ALCALINO A TRAVES DE UNA MULTITUD DE CAMARAS CON CELULAS ELECTROLITICAS; SE RECOGE LA SOLUCION DE SULFATO ALCALINO EN LA CAMARA CENTRAL DE LA PRIMERA CELULA FOTOELECTRICA; SE DIALIZA A TRAVES DE MEMBRANAS INTERCAMBIADORAS DE IONES, LA SOLUCION ELECTROLITICA DE LA SERIE DE CELULAS ELECTROLITICAS; SE EXTRAE LA SOLUCION ELECTROLITICA DE LA CAMARA CENTRAL DE LA ULTIMA ZONA DE LA SERIE DE CELULAS ELECTROLITICAS Y SE SUMINISTRA DE NUEVO A LA PRIMERA CAMARA DE LA PRIMERA ZONA DE CELULAS ELECTROLITICAS DE LA SERIE EN CUESTION, LA SOLUCION ELECTROLITICA EXTRAIDA DE LA ULTIMA ZONA. CON EL PROCEDIMIENTO SE CONSIGUE UNA ELECTROLIZACION DEL 80%.
