Abstract

PROCEDIMIENTO PARA EL TRASLADO, MANIPULACION Y ALMACENAMIENTO DE HIDROXIDO DE ALUMINIO HIDRATADO HUMEDO. ESTE SE DESCARGA SOBRE EL CARGADOR DE CAJON (2) POR MEDIO DEL VOLQUETE (1). EL CARGADOR DE CAJON (2) CARGA EL HIDROXIDO DE ALUMINIO HIDRATADO HUMEDO SOBRE EL TRANSPORTAR VERTICAL DE DOBLE CINTA (4) MEDIANTE LA CINTA DE PLACAS ARTICULADAS (3). EL TRANSPORTADOR (4) CARGA SU CONTENIDO SOBRE LA BASCULA DE CINTA DE MEDICION (5). UNA VEZ PESADO SE CONDUCE AL DEPOSITO DE ALMACENAMIENTO (6), DONDE SE LE AÑADE LEJIA DE SOSA ACUOSA CORRESPONDIENTE A LA CANTIDAD DE HIDROXIDO DE ALUMINIO HIDRATADO HUMEDO PESADO. POR LA CONDUCCION DE ALIMENTACION (9) SE CALIENTA EL LODO OBTENIDO Y SE PREPARA UNA SUSPENSION BOMBEABLE Y DOSIFICABLE DEL COMPUESTO POR MEDIO DEL MECANISMO DE AGITACION (8). EL CITADO CALENTAMIENTO SE REALIZA HASTA TEMPERATURAS QUE OSCILAN ENTRE LOS 20 G Y LOS 100 GC. LA SUSPENSION OBTENIDA TIENE UN CONTENIDO DEL 29 AL 49 POR 100 EN PESO DE AL2O3 DEL 6 AL 19 POR 100 DE NA2O Y UN 41 A 56 POR100 DE H2O. A
