Abstract
The pulp and paper processes are very sensitive to changes in the chemical state of the pulp. Both the product quality and the smooth operation of the process are affected by the variations and load changes in the chemical content. What makes the situation even worse is the fact that these phenomena have slow dynamics. Every corrective action can be seen only after a significant time delay. The trend of today in paper and pulp making is to build faster systems with small volumes (small residence times for unit operations) creating exceedingly difficult control problems. This paper presents a stable and robust method of modeling and describing the significant chemical phenomena in pulp. Practical examples are given in calcium carbonate systems.
