Abstract

A device for regulating the operation of a chemical treatment plant, by attenuation of the variances of the regulating parameters, has a calculation circuit connected to a measuring device for measuring flows of compounds at the input of the plant and measuring devices for measuring the contents of residual input compounds still present at the output of the plant. The calculation circuit performs coherence processings of the measured values to attenuate the variances of these values. The measurement provides a set-point signal which is used for the regulation of the plant.
