Course syllabus and organization
Single session
Responsible
Lesson period
Second semester
Prerequisites for admission
Basics of Stoichiometry, Mathematics and Physics. Knowledge of Physical Chemistry (thermodynamics and kinetics) and of transport phenomena.
Assessment methods and Criteria
Fundamental unit
Written + oral examination: The written test includes the solution of exercises similar to those presented during the course. The oral examination includes the discussion of a flow sheet and two questions, one regarding the sizing examples of a unit operation and the other is relative to applied thermodynamics.
For the Lab unit, practical experiments will be carried out in groups of 3/4 students. The Group will lay down a report that will be discussed with the teacher.
Overall the exams will aim to:
1) check the ability to size a unit operation
2) check the ability to choose the most appropriate thermodynamic package to describe the system
2) understanding the principles and experiments deepened in the lab.

Teaching methods
Students will carry out practical exercises in groups of 3-4 people. At the end of the laboratory, each group will have to prepare a written report, with the collected results and numerical and simulation elaborations explained in class. Each student will then have to have an oral examination. In this exam, the knowledge of the experimental plants and procedures, of the numerical elaborations and of the process simulation will be verified.
