My research project

The project will be done in collaboration with the paper mill AssiDomän Frövi in Sweden. AssiDomän Frövi AB is producing 300 000 tons of cartonboard per year. The main goal of the project is to model the moisture content during the drying of the cartonboard, since it is an important parameter for the quality of the paper.

A preliminary model, implemented in object oriented simulation tool Dymola includes the moisture content of the paper during the drying section, but is not included it in the different layers. The project will consist on implementing the four layers of the papersheet, using the grey-box modelling and identification.
Partners:

The paper mill AssiDomän Frövi
The developper of the simulation tool Dymola, Dynasim
The developper of an adapted library for pulp and paper, Solvina
The Royal Institute of Technology of Stockholm, KTH
