OPTIMIZE - Optimized CTMP processes

Purpose and goal:

The purpose of the project is to develop an optimization tool for more even quality and reduced energy use. The optimization tool will be developed and evaluated at a CTMP pulp mill. The main goal is for the tool to be installed and used> 95% of the operating time of CTMP.

The energy goal will be achieved by the tool enabling an increase in production. The saving potential is estimated to 25-50 GWh / year.

The tool will also ensure a reduced quality variation corresponding to 50% of selected pulp properties (preferably fiber length, tip and freeness). Expected results and effects:

The result from the project will be an optimization tool that can be used by different staff categories in the pulp mill. The tool will provide a basis for: * Energy and pulp quality optimization * Production plannning * Optimization of the total electricity use * Controller tuning from a system perspective

* Analysis of the impact of system disturbances throughut the process Approach and implementation: The project is carried out in two main phases.

I In the first phase, the interaction interface for the tool and the tool´s basic functions are developed. This is done iteratively in a series of interviews with the mill´s staff.

I in the second phase, the functions are further developed to include production planning and an overall control strategy for the entire system.
