Abstract

"MéTODO E SISTEMA PARA ALIMENTAR APARAS DE CELULOSE PARA UM SISTEMA DE COZIMENTO CONTìNUO EM ALTA PRESSãO". A presente invenção refere-se a um método para alimentar um material fibroso celulósico para um vaso de processamento em alta pressão, que inclui as etapas de: pressurizar um fluxo em baixa pressão do material fibroso em um dispositivo de transferência em alta pressão; descarregar um fluxo em alta pressão do material fibroso a partir do dispositivo de transferência para um conduto em comunicação direta com o vaso de processamento; descarregar um fluxo em baixa pressão do fluido e material fibroso a partir do dispositivo de transferência; a jusante do dispositivo de transferência, pressurizar o fluxo em baixa pressão descarregado; e juntar o fluxo de descarga em baixa pressão pressurizado com o fluxo em alta pressão descarregado.
