Abstract

PROCESSOS E SISTEMAS PARA A TRANSFORMAçãO EM POLPA DE MATERIAIS LIGNOCELULóSICOS. Um recipiente de não-compressão, tal como um digestor, é empregado para o pré-condicionamento químico das lascas seguido por um dispositivo de fibração para separar as lascas pré-condicionadas em feixes de fibra, que são então lavados antes de um tratamento químico de alta consistência. O digestor pode ser um tal como usado em transformação em polpa química convencional de madeira com ou sem telas para a extração de agente químico. Se extraído este agente químico poderia ser recirculado para o digestor com tratamento na alça de circulação tal como aquecimento ou a adição de diluição ou outros agentes químicos. O digestor pode ser hidráulico ou de fase de vapor (que está contido em um espaço de vapor dentro do digestor) e opera de uma maneira ou contínua ou em batelada. O digestor permite a descarga de material sem o uso de um mecanismo de pressionamento. O material tratado no digestor é então desfibrado para converter as lascas em feixes de fibra contínuos, que são então lavados e têm água retirada. A polpa lavada e sem água é então tratada com agentes químicos peróxido alcalino para desenvolver brilho e outras propriedades de polpa.
