A SYSTEM AND A METHOD FOR OPTIMIZATION OF CONTINUOUS DIGESTION PROCESS

摘要

A method for optimization of continuous digestion process is provided which aims to control the delignification process in a continuous pulp digester in an optimal way for different pulp grades taking care of the process disturbances and model uncertainties. This is achieved by customizing a generic mathematical model for continuous digestion process which runs through software application on a dedicated electronic means. The model is updated periodically based on online information and used with a plant optimization component involving multiobjective optimization to evaluate the optimal set points for the controllers.
