Process-control and automation for chemical recovery within the pulpindustry

Important results from the project

In line with the purpose and goal of the call, this pre-study has created a foundation for future projects to implement process monitoring. A continuation of the field test conducted may be realized already during the spring of 2016. Södra Cell has also joined a new consortium that aims to develop a fiber optic temperature sensor. The collaboration has given Södra Cell a better view of the possibilities with fiber optic measurements while Acreo and Proximion have gained a better understanding of their technologies can benefit the end-user.

Expected long term effects

The pre-study has resulted in knowledge that serves as base for discussions on future projects to implement process monitoring. To Proximion this is a probable business opportunity for their temperature sensing fiber gratings and Södra Cell is expected to benefit from more efficient in their lime-kiln operation.

Approach and implementation

This pre-study was a collaboration between Acreo , Proximion and Södra Cell, which was con-ducted in four parts. First the needs of Södra Cell were analyzed and suitable technologies were suggested based on that analysis. Then a field test, that evaluated one of the technologies, was conducted, which gave input to the final discussion on the utilization of the results. Together, this has given good opportunities for future projects.
