Abstract

METODO PARA DETECTAR MEMBRANAS DE INTERCAMBIO IONICO DEFECTUOSAS EN ELECTROLIZADORES MONOPOLARES Y BIPOLARES PARA LA PRODUCCION CLORO-ALCALI, COMPRENDE REDUCIR LA CARGA ALECTRICA DEL ELECTROLIZADOR HASTA 2-10% DE LA CARGA NOMINAL Y, BAJO ESTAS CONDICIONES DE CARGA REDUCIDA, MEDIR LA UNICA CARGA DE CORRIENTE ELECTRICA ABSORBIDA POR CADA CUBA ELEMENTAL EN UN ELECTROLIZADOR MONOPOLAR Y MEDIR EL UNICO VOLTAJE ELECTRICO DE LA CUBA ELEMENTAL EN EL CASO DE LOS ELECTROLIZADORES BIPOLARES. EL METODO COMPRENDE ADEMAS CALCULAR LAS DESVIACIONES DE LA CORRIENTE O VOLTAJES UNICOS CON RESPECTO A LOS VALORES MEDIOS. TODAS LAS MEMBRANAS QUE PRESENTAN VALORES COMPRENDIDOS ENTRE UN VALOR DE UMBRAL DETERMINADO SE CONSIDERAN COMO ADECUADAS PARA SU OPERACION.
