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.IMPROVED FIBER LINE SYSTEMS, PROCESSES AND METHODS. The present invention relates to a chemical pulp milling system and method of using black liquor volatilization steam in the digester system, sending the black liquor to an evaporation system without using any pre-evaporation system, volatilizing the black liquor. in the evaporation system to produce steam, and using at least some vapor to vaporize the chip in a chip reservoir and / or to supply the direct heat exchangers in the digester system to preheat white liquor and / or filtered liquids for use in the vaporizer. Digestive system. In other embodiments, a chemical pulp milling system and method for utilizing instant black liquor steam from a digester system comprises generating black liquor from the digester system, volatilizing the black liquor at one stage to produce steam before tanking the black liquor. evaporation system storage, using steam to vaporize chips and / or to evaporate black liquor in the evaporation system, and prevent formation of non-condensable concentrated gases and fouling condensate in the digestor system using the digester system without any condenser for the steam. volatilization of black liquor.
