Some of the available dates of the course "Case Studies in Process Design" on Wednesdays, 2-5 pm, are used for exercises in "Process Simulation and Flowsheeting" (e.g. with Aspen, gPROMS, Matlab, etc.). The participation in these exercises is considered critical for understanding and practicing the content of the course, and therefore, preparing for the written exams. Every student is asked to hand a report for these exercises. The reports are corrected and graded to provide the necessary feedback to the students.
