65773 - Mechanical Plants

Learning outcomes

The student acquire the skills for designing and commissioning mechanical industrial plants. Particularly, the student will be able to: • Design the executive project of the industrial mechanical plant starting from the Process Flow Diagram (PFD); • Develop the test activities for the plant commissiong ; • Prepare the technical documentation necessary for the certification of the mechanical plants. The student also knows: The set of rules that oversees the placing on the market of the plant.

Slides on Cesare Saccani official Web site.

Teaching methods

Lectures in classroom. Practical exercises in classroom, in laboratory and at industrial companies.

Assessment methods

The final exam consists of a written and an oral assessment aiming at assessing the learning of the design methodology of mechanical industrial plants learned during the course.

In the final test it is also evaluated the ability to define P&IDs, schemes and thermodynamic diagrams and to size the main components.
