Abstract

"MéTODO PARA O COZIMENTO CONTìNUO DE POLPA DE CELULOSE". A presente invenção diz respeito a um procedimento para o cozimento contínuo de polpa de celulose, compreendendo um vaso de impregnação (101) e um digestor (102). Os cavacos são impregnados no vaso de impregnação (101) e são alimentados depois de impregnação juntamente com fluido de circulação através de uma linha de transferência (103) para um separador de topo (105) sobre o digestor (102) de maneira a serem cozinhados. Uma fração do fluido de circulação é extraída (retirada) em um separador de topo (105) e retornada para o fundo do vaso de impregnação (101) por intermédio de uma linha de retorno (106). Licor negro é extraído a partir do digestor (102) por intermédio de uma linha de licor negro (108) para o vaso de impregnação (101). Em concordância com a presente invenção, o referido método está caracterizado pelo fato de que um trocador de calor (107) está disposto entre a linha de retorno (106) e a linha de licor negro (108), o que possibilita a troca de calor entre a linha de retorno (106) e a linha de licor negro (108), mas ao mesmo tempo não possibilita a troca de fluido, e de que a temperatura do licor negro na linha de licor negro (108) depois de passagem através do trocador de calor (107) tendo sido resfriada por 10<198>C - 15<198>C.
