Energy efficiency is one of the main aspects in the Kraft pulping process. In Kraft pulping, the delignification of the pulp is mainly controlled by temperature and alkali. However, the quality is usually measured only in the blowline of the digester

In this study, the fault tolerant Kappa number control in continuous cooking application is investigated. The Kappa number is one of the quality measures in the pulp cooking process and usually the only on-line measurement. It is a measure of the res

In industrial continuous cooking systems, yields are seldom measured online. In this study, profiles for lignin, carbohydrates and total yield are constructed using physical model. The yield profiles are utilized for two kinds of digesters: conventio

Two industrial continuous cooking processes producing both softwood and hardwood pulp were studied. Real time kappa number profiles of conventional and Downflow Lo-Solids cooking were modelled. Gustafson's kappa number model with optimised parameters

Industrial systems generate a lot of information for operators. Increased measurement information flow might cause difficulties for the process operators to observe the process states and faulty process operation. In this study, measurements and stat

In industrial digester control systems Kappa number models are often used. There are publications using both physical and experimental methods. In this study Kappa number is predicted in the top of the digester using both modelling techniques. Physic

The increasing requirements for better quality with smaller variations are often difficult to fulfill in pulping plants. In Chemi-Thermo Mechanical Pulping (CTMP), the non-uniformity in the chemical treatment and the changes in the refiner's energy c
