Abstract

It is the aim and object of the invention to provide a process for producing pulp, which allows the process of digesting wood to be carried out in a controlled manner, so that a pulp of uniform quality is obtained. This object is achieved in such a way that, in the process for producing pulp by the acid bisulphite process, the parameters are determined, with which the bisulphite process is the standard, the set values of process-relevant variables are determined from these parameters, these process-relevant variables are repeatedly determined in the course of the process, a set/actual value comparison is carried out and, in the case of agreement, the process is stopped.
