Abstract
PROCEDIMIENTO PARA LA PURIFICACION DE ACIDO FOSFORICO. LA PURIFICACION SE REALIZA EN UNA INSTALACION DE EXTRACCION DE VARIAS ETAPAS EN PRESENCIA DE ACIDO SULFURICO CON AYUDA DE DISOLVENTES ORGANICOS. LOS IONES SULFATOS SE ELIMINAN POR ADICION DE COMPUESTOS DE BARIO AL ACIDO FOSFORICO A PURIFICAR, DISPERSANDOSE LA FASE ORGANICA DE DISOLVENTE EN LA ACUOSA. EL ACIDO SULFURICO ES CONDUCIDO EN CONTRACORRIENTE CON EL ACIDO FOSFORICO.
