Abstract
"PROCESSO PARA COZIMENTO CONTìNUO DE POLPA". A presente invenção se refere a um processo para cozimento contínuo de pedaços de madeira em pressão elevada e temperatura elevada em um digestor vertical (1) para produção de polpa dissolvida quimicamente. Material de fibra e licor de cozimento são introduzidos no topo do digestor e polpa é descarregada a partir do fundo do digestor (1), por intermédio de uma linha (8) na qual a polpa é mantida em substancialmente o mesmo nível de pressão, para uma lavagem pressurizada (7). Mais do que 50 % do licor de cozimento usado (licor negro) que é extraído a partir do sistema no total é extraído a partir do filtrado de lavagem da lavagem pressurizada. Ao mesmo tempo uma pequena porção do filtrado de lavagem está também para ser recirculada para o fundo do digestor como líquido de diluição. A lavagem pressurizada é regulada de maneira tal que uma alta temperatura é mantida no filtrado de lavagem. A extração é regulada de maneira tal que um fluxo concorrente é estabelecido no fundo do digestor. A presente invenção permite produção aumentada em digestores sobrecarregados onde extrações substanciais de licor de cozimento a partir do digestor são tornadas difíceis pela velocidade de polpa aumentada em direção abaixo através do digestor.
