Teaching methods
This course combines ex-cathedra teaching, exercise sessions and projects with tutoring.
The theoretical courses are ex-cathedra. The students are encouraged to ask questions. In the context of the course, a number of scientific papers have to be read and analyzed.
The exercises focus on performing mass/species balances and energy balances for different processes, the safety analysis of a process, the modeling and simulation of well-mixed reactors (batch and continuous) and plug flow. Apart from exercise sessions, two mini-projects are planned to train students in the study and understanding of different aspects of a chemical process independently.
Example mini-project 1 : "Simulation of a commercial reactor for steam cracking of ethane" allows students to apply reactor modeling concepts in particular for plug flow reactors, reaction kinetics and numerical methods to a practical case of great industrial importance. With the developed simulation code of simulation, a sensitivity study is be performed. The coupling reactor - furnace must be considered in the analysis of the results.
Example mini-project 2 : "Sulfuric acid production: design of the global process and thermodynamic study of the oxidation of SO2 to SO3" allows students to study the mass and energy balances of an industrial process and to identify thermodynamic constraints of conversion.
In addition to developing students' technical skills, the mini-projects also aim to teach students how to report a technical study scientifically and concisely, both writing and orally, in front of an audience.

Evaluation methods
The students will be individually graded based on the objectives indicated above. The theoretical exam is with a written preparation and oral defense/discussion. It counts for 70% of the mark. An exercise is part of the exam.
Evaluation of the mini-projects
One/two mini-projects (defined in the section on Learning methods) are evaluated. They count for 15/30% of the mark.
