Abstract

SE DESCRIBE UN PROCEDIMIENTO POR LOTES MEJORADO, PARA LA PREPARACION DE CELULOSA KRAFT, EN EL QUE SE INTRODUCE UNA FRACCION DE LEJIA VERDE O UN DERIVADO DE LA MISMA EN LA FASE DE IMPREGNACION Y/O PRETRATAMIENTO. EL DERIVADO PUEDE SER AGUAS MADRES PROCEDENTES DE LA CRISTALIZACION DE CARBONATO A PARTIR DE LEJIA VERDE. DICHO PROCEDIMIENTO FACILITA LA UTILIZACION DE CONDICIONES SUAVES EN LA FASE FINAL DE COCIDO ASI COMO PERIODOS CORTOS DE COCIDO, PRODUCIENDO UNA CELULOSA DE MAYOR CALIDAD, UN ELEVADO RENDIMIENTO DE PRODUCCION Y UN BUEN MANTENIMIENTO DEL EQUILIBRIO DE LOS PRODUCTOS QUIMICOS EN LA AMASADORA.
