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.

The simulation project has to follow the following sequence:

1. Literature search.

2. Specification of the objectives (purity, energy integration,

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.
