Abstract

UN METODO Y PLANTA PARA UN TRATAMIENTO TERMICO DE LODO DE CAL (CACO{SUB,3}) FORMADO MEDIANTE EL PROCESO DE CAUSTIFICACION DURANTE LA MANUFACTURA DE PULPA DE PAPEL.EL LODO DE CAL ES SECADO Y PULVERIZADO EN UNA PRIMERA ETAPA DEL PROCESO Y PRECALENTADO EN UNA SEGUNDA ETAPA DEL PROCESO POR MEDIO DE UN GAS DE ESCAPE CALIENTE QUE VIENE DE UN HORNO.CON MOTIVO DE ASEGURAR QUE LA TEMPERATURA EN LA SEGUNDA ETAPA DEL PROCESO NO EXCEDA UNA TEMPERATURA PREDETERMINADA QUE ESTA EN EL RANGO DE 400-600 C, SE REGULA LA RELACION ENTRE LA CANTIDAD DE ENERGIA DISPONIBLE EN EL GAS DE ESCAPE PARA EL CALENTAMIENTO EN LA SEGUNDA ETAPA DEL PROCESO Y LA CANTIDAD DE ENERGIA ACUMULADA EN EL MATERIAL QUE VA A SER CALENTADO.
