CONCLUSIONS
The methodology used in this work has been applied for several years in
the subject Simulation of Chemical Processes. The main conclusions that
can be drawn are:
- A significant success in the achievement of learning outcomes is obtained, and
also a high percentage of students that pass the subject every year.
- Many outcomes not directly related to the subject but very important for the
professional development of chemical engineers are achieved with the
methodology used in this subject.
