ABSTRACT:
Continuous measurements are made of a characteristic of the individual components of green liquor fed to a slaker and white liquor exiting from the slaker. The liquor component measurements provide a precise characterization of the liquors allowing for a more efficient control of the causticizing reaction in the kraft process. The individual component measurements are provided as inputs, along with certain ambient measurements, to a non-linear controller. The controller produces a causticizing control signal which is used to control the amount of lime introduced to the slaker. The controller is adapted to a particular process installation through the application of data collected from that installation. The controller, for example a neural network or fuzzy logic controller, produces a causticizing control signal according to unique parameters developed for the specific installation.
