Lesson period
Second semester
Module Chemical plants:
All the lectures will be available in asincronous mode on the Ariel site of the course and in the Teams channel.
Synchronous lectures will be planned ca. every 2 weeks for question/answer time and for exercises. Ilenia Rossetti ([email protected]) is available to plan specific further meetings for single students or groups upon appointment.
If the conditions will allow attending the informatic laboratory we will take exercises for process simulation, otherwise examples will be proposed in streaming.
Programs and exams will remain unchanged. The examinations will take place by using the platforms Zoom and Exams for the written part, while oral exams will take place on the Zoom and teams platforms.
Module Laboratory:
Theoretical lessons (16 hours) will be carried out online via the Microsoft Teams platform in synchronous mode with respect to the timetable set in the academic calendar. All lessons will be recorded and videos will always be available on the Ariel platform, on the course page. For any doubt, clarification or need, it will always be possible to contact the teacher via email ([email protected]) to define an appointment for a call through Microsoft teams individually or in a group of students. We guarantee an immediate response and an appointment within 1-2 working days. In case of overlapping of the lessons with other courses with didactic laboratories, alternative days and times will be identified to allow maximum participation in the synchronous lessons. The Ariel platform will be the reference for all communications, notices and discussions.
For laboratory exercises, a calendar will be drawn up to allow activities in attendance with the number of students suitable for working safely within the laboratory.
Reference materials:
The program and the reference material will not change.
Learning verification procedures and assessment criteria:
The description of what has been done in the laboratory, the results collected and the required elaborations will be reported in a document to be delivered to the teacher. An oral exam will then be conducted remotely with the use of the Microsoft Teams platform. To verify the learning of the process simulation software, we will carry out exercises remotely by sharing the screen

Prerequisites for admission
Basics of Stoichiometry, Mathematics and Physics. Knowledge of Physical Chemistry (thermodynamics and kinetics) and of transport phenomena.
Assessment methods and Criteria
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 with sizing examples of a unit operation.
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.
