摘要
The present invention relates to a process for the delignification with oxygen of paper pulp, characterized in that it includes the following steps: / p & & p a) for delignifying the pulp with oxygen, up to a given degree of delignification, in at least two consecutive stages 14, 22, 32, the treatment time in each stage being almost equal; and / p & & p & b) to be washed in 16, 26, the dough between each of these at least two consecutive stages, in order to maximize the viscosity for a degree of delignification.
