Topic outline

  • About the course

    CHEM-E1210 Bioproduct Mill Recovery Processes is an advanced level of course in which the students are expected to have prior knowledge on biomass and its industrial processing. The focus will be in the kraft process that is the dominant one among all chemical fractionation processes of biomass. Lectures will be organized twice a week (see preliminary schedule below) and they will be given mostly by experts from the industry. In addition there will be weekly exercises (except for the first lecture week) in which students work in groups on selected topics related with the lectures. During the last week, the groups will present a short summary (10 min + 5 min discussion) on their topic. The short laboratory sessions will be introduce the different flows, intermediates and products of the recovery processes. Due to the Covid-19 situation, students will be divided to 2-3 laboratory groups and the details of the schedule will be agreed during the course. Forms of passing and grading the course will be agreed with the students on the introductory lecture.
