Abstract

UN METODO PARA LA RECUPERACION Y EL RECICLADO DE HIDROXIDO DE SODIO DESDE LA DISOLUCION DE DESPERDICIOS DE OPERACIONES DE CORROSION DE ALUMINIO. EL METODO UTILIZA UNA COLUMNA DE MEMBRANA DE DIALISIS O BLOQUE PARA EXTRAER INICIALMENTE EL HIDROXIDO DE SODIO DESDE LA SOLUCION DE DESPERDICIOS Y VOLVERLO A LA SOLUCION BASE DEL TANQUE DE CORROSION EN UNA CONCENTRACION SUFICIENTE PARA LLEVAR A CABO LA OPERACION DE CORROSION BASICA. EL METODO PERMITE LA RECUPERACION DE CANTIDADES SALABLES DE HIDROXIDO DE ALUMINIO.
