Abstract
PROCEDIMIENTO CONTINUO MEJORADO PARA LA PRODUCCION DE CLORATO SODICO, MEDIANTE ELECTROLISIS DE CLORURO SODICO CONTAMINADO CON SULFATO SODICO, EN DONDE LA CONCENTRACION DE SULFATO EN EL SISTEMA SE MANTIENE POR DEBAJO DE UN NIVEL PRESELECCIONADO. UNA PORCION DEL LICOR MADRE QUE PERMANECE DESPUES DE LA CRISTALIZACION DE PARTE DEL PRODUCTO DE CLORATO SODICO, SE ENFRIA ADEMAS, SELECTIVAMENTE, PARA EFECTUAR LA CRISTALIZACION DE PARTE DEL SULFATO SODICO PRESENTE EN EL LICOR. SE ESTABLECE UNA CONCENTRACION <REGIMEN CONSTANTE> ACEPTABLE DE ION SULFATO, LO CUAL IMPIDE LA EXCESIVA Y PERJUDICIAL ACUMULACION DE ION SULFATO EN EL SISTEMA ELECTROLITICO.
