Abstract
SISTEMAS, PROCESSOS E MéTODOS DE LINHA DE FIBRA APERFEIçOADOS. A presente invenção refere-se a um sitema de moagem de polpla química e método de usar vapor de volatilização de licor negro no sistema digestor, enviando o licor negro a um sistema de evaporação sem usar qualquer sistema de pré-evaporação, volatilizando o licor negro no sistema de evaporação para produzir o vapor, e usando pelo menos algum vapor para vaporização da lasca em um reservatório de lascas e/ou para suprir os trocadores de calor direto no sistema digestor para preaquecer o licor branco e/ou líquidos filtrados para uso no sistema digestor. Em outras modalidades, um sistema de moagem de polpa química e método para utilizar vapor instantâneo de licor negro de um sistema digestor compreende gerar licor negro do sistema digestor, volatilizando o licor negro em um estágio para produzir vapor antes de levar o licor negro em tanque de armazenagem do sistema de evaporação, usando o vapor para vaporizar lascas e/ou evaporar licor negro no sistema de evaporação, e impedir formação de gases concentrados não condensáveis e condensado de incrustação no sistema digestor usando o sistema digestor sem qualquer condensador para o vapor de volatilização de licor negro.
