etc).
3. Definition of the calculation basis and the flow diagram.
4. Simulation of the chemical plant using Aspen Plus and
Aspen HYSYS software.
5. Preparation of a final report with the developed
simulation project.
6. Oral presentation.

CONCLUSIONS
DEPARTMENT OF CHEMICAL ENGINEERINGUCLM
18
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.
