Abstract

PROCEDIMIENTO CONTINUO PARA PRODUCIR UN GEL DE HIDROXI Y CARBONATO DE ALUMINIO. COMPRENDE: A) COMBINAR CARGAS DE UNA SOLUCION ACUOSA DE CARBONATO DE ALCALI Y UNA SOLUCION ACUOSA DE SAL DE ALUMINIO, PARA PREPARAR UNA MEZCLA DE REACCION ACUOSA ACIDA; B) OTENER HIDROXIDO DE ALUMINIO A PARTIR DE LA MEZCLA DE REACCION; C) EXTRAER DE FORMA CONTINUA DE LA MEZCLA EL PRODUCTO EN FORMA NO EQUILIBRADA; D) MANTENER EL PH DE LA MEZCLA DE REACCION EN UN VALOR PREDETERMINADO (G0,1), PARA PROEDUCIR UN GEL CON UN CONTENIDO DE IONES ALCALINOS DE 0,08 MG Y E) RECUPERAR DEL GEL AL HIDROXIDO DE ALUMINIO. SE UTILIZA EN PROCESOS DE FABRICACION.
