Abstract

SE PRESENTAN METODOS PARA DESCARGAR LAS SOLUCIONES DE COCCION AGOTADAS DE UN DIGESTOR POR LOTES QUE CONTIENE MATERIAL CON CONTENIDO DE LIGNOCELULOSA COCIDA EN UNA SOLUCION DE COCCION AGOTADA, QUE INCLUYE EL SUMINISTRO DE UNA PRIMERA PARTE DE LA SOLUCION DE LAVADO AL DIGESTOR PARA DESPLAZAR UNA PRIMERA PARTE DE LA SOLUCION DE COCCION AGOTADA A UNA TEMPERATURA Y EL CONTENIDO DE MATERIAL SOLIDA SECA QUE SUSTANCIALMENTE SE CORRESPONDE CON LA TEMPERATURA Y CONTENIDO DE MATERIA SOLIDA SECA DE LA SOLUCION DE COCCION AGOTADA EN EL EXTREMO DE LA DIGESTION POR LOTES. SUMINISTRANDO ENTONCES, UNA SEGUNDA PARTE DE SOLUCION DE LAVADO AL DIGESTOR PARA DESPLAZAR UNA SEGUNDA PARTE DE LA SOLUCION DE COCCION AGOTADA QUE TENGA UNA TEMPERATURA Y UN CONTENIDO DE MATERIA SOLIDA SECA SUBSTANCIALMENTE INFERIOR QUE LA DE LA SOLUCION DE COCCION AGOTADA EN EL DIGESTOR, Y MANTENIENDO LA PRIMERA Y SEGUNDA PARTES DE LA SOLUCION DE COCCION AGOTADA SEPARADAS UNA DE LA OTRA. TAMBIEN SE PRESENTAN METODOS PARA PRODUCIR PULPAPARA PAPEL KRAFT EN PROCESOS DE DIGESTION POR LOTES.
