A method for the continual, real-time, in-situ generation of a Kappa number used by a process control system to control the delignification of papermaking pulps is disclosed. The method converts a plurality of analog output signals representing the intensities of spectral bands of light energy reflected by the pulp, and feedback analog output signals representing the intensities of spectral bands of light energy before they are injected into the pulp, into digital output values. The digital output values are then normalized in accordance to a normalization algorithm and stored with a time marker. The normalized values are used along with previously-stored coefficient values that represent a model of the delignification process for any particular point in time, and in accordance to the time marker and configuration data from a configuration computer, a Kappa number representation is calculated in accordance to a Kappa number-generating algorithm. The Kappa number representation is then converted into a signal form acceptable by the process control system and used to control the delignification process.
