    Process modelling for more efficient pulp and paper manufacturing

    Integrated paperboard manufacturing consists of a number of unit processes that continuously generate large amounts of process data. Manufacturing is energy-intensive and variations must be taken into account to achieve the optimal production process. A new thesis at Karlstad University shows how different mathematical models can be applied to the processes in aspects of improved product quality and reduced energy use.

    “I have studied the conditions that exist for statistical and mechanistic models for predicting pulp and paperboard properties and for increased energy efficiency”, says Daniel Ekbåge, who successfully defended his doctoral thesis on process modelling in pulp and paper manufacturing.

    VIPP Graduate School about to reach finishing line

    VIPP Graduate School, which started in 2011, will reach the finishing line at the end of 2020. The occasion is celebrated with an event in connection with Papermakers Light on 12 November.

    “During this year, we will work hard to complete all projects and create conditions that will enable all our doctoral students to graduate”, says Magnus Lestelius, professor of chemical engineering and new programme director of VIPP Graduate School. “We are going to make use of our experiences from the graduate school as we plan for the future and continued collaborations with the business sector. We hope that the event will be a memorable occasion, as well as the start of something new.”

    Analysis method crucial for correct results in coronavirus research

    Researchers in analytical chemistry at Karlstad University have published an article on the analysis of how the coronavirus attaches to receptors in the human body. They argue that existing research in the field has drawn incorrect conclusions due to simplified calculation methods.

    “We were interested in using our new advanced method of calculating interactions on surfaces, which Patrik Forssén, doctor of data processing, developed in collaboration with us to contribute to a better understanding of the infection mechanisms of Covid-19”, says Torgny Fornstedt, professor of analytical chemistry. “However, we were not able to perform Covid-19 experiments at short notice, including taking into account all safety aspects, and we also needed a test case for research applications.”

    Per Hurtig new docent in computer science

    Per Hurtig is the most recent docent at the Department of Computer Science. His research is about making communication on the internet faster and more efficient.

    - The number of connected units has increased tremendously in recent years, which in turn has sharpened the quality requirements considerably”, says Per Hurtig. “Both applications and users now depend on higher quality in terms of faster connection and less delays. My research is very much about how users of connected devices, such as mobile phones, can have a better experience.

    Three focus areas
    Since his thesis defence in 2012, Per’s work has been focused on three areas that reflect mobile usage and its development in society.

    Faster and Greener Purification Process with Carbon Dioxide

    In order for pharmaceuticals to be safe, they must be clean of pollutants. Carbon dioxide can be used to make the purification process more environmentally friendly, which may seem paradoxical since carbon dioxide is usually associated with a negative climate impact. However, if carbon dioxide is recovered from other existing processes and if the use of environmentally hazardous organic solvents is reduced, large gains can be made both economically and environmentally.

    “More knowledge of how the separation system works makes it easier to predict how to design an optimal system,” says Emelie Glenne, who recently defended her doctoral thesis in chemistry.

    Chromatography is a separation technique used both to purify samples and to analyse which substances a sample contains. The method is based on the substances to be separated being distributed between a stationary and a mobile phase. In her thesis, Emelie Glenne has focused on so-called supercritical fluid chromatography, SFC.

    New Honorary Doctor wants to protect data privacy

    During her years as a researcher and data protection commissioner, the German computer scientist Marit Hansen has been a pioneer for the concept of privacy enhancing technologies (PET). Her contribution to education and research within the field at Karlstad University has awarded her an honorary doctorate at the Faculty of Health, Science and Technology.

    Marit Hansen is a pioneer who, for the past 25 years, has been working outside of academia within the fields of data protection, personal integrity and security, using both technology and legislation. She has been working as a data protection commissioner in the state of Schleswig-Holstein in Germany since 2015, and is also involved in several other projects within the field. In 2018, she was appointed member of the National Commission on Data Ethics in Germany. Marit Hansen has in public debates and in discussions with politicians fought for data privacy as a fundamental civil right.
