PROCESS STABILIZATION AND IMPROVED ENERGY EFFICIENCY THROUGH REFINING ZONE TEMPERATURE CONTROL
This paper presents a new refiner control system that can accomplish stabilization of the process conditions as well as constitute a tool for better energy efficiency. The control system TCtrl has a cascade structure where temperature is controlled in the inner loop while the outer loop handles pulp properties. Hydraulic pressures are used for controlling the maximum of the refining zone temperature profile. The results show a stabilization of the entire temperature profile and thereby, stabilization of motor load and pulp property variables is obtained. The presented refining control strategy comprises new process perspectives which are essential if improved energy efficiency is to be obtained.
