THE MAIN OBJECTIVES OF SIMULATION OF CHEMICAL PROCESSES SUBJECT
-To introduce process simulators to undergraduate students.
-To train engineers the use of commercial simulation software (Aspen Plus) for the
simulation of basic fluid flow operations, heat and mass transfer and the
calculation of chemical reactors.
-To simulate the most common chemical processes with Aspen Plus and Aspen
HYSYS software and to compare the obtained results.
-To learn about the process analysis and conceptual designs of chemical processes.

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.
