Obiettivi dell'insegnamento

The course is amied at providing general and detailed information about non-conventional unit operations in chemical processes and plants. The final target is to raise the skills to recognize the units and their operation strategy within real industrial contexts.

In addition, a relevant target is the improvement of the skills for the design and operational purposes of the main unit operations and related ancillary units and the knowledge of the process environment, their limitations, and their nominal operating conditions with the achievement of a contextualization of the targets and operations of the single unit within the overall chemical process.

The course is finally aimed at deepening the comprehension abilities and capabilities of the students as well as their own decision making and making judgement skills in the selection of competing solutions to achieve the best process performances. Moreover, the enrichment of technical language, EPC and field procedures and technicalities and technical team interaction and leadership is another relevant target.

Modalità di valutazione

The exam is written only. Beyond the threshold of 27/30 at the written exam, students have the possibility to ask for additional oral exam to refine the final mark.

The exam is structured with (1) open questions and (2) quantitative exercises.

Elements (1) allow assess the skill advances on the knowledge of non-conventional unit operations and in making judgement in the selection of unit operations and strategies. Skills on technical communication and reporting are also assessed.

Elements (2) allow to assess the skill advances for design and operational purposes. Skills on process control are also assessed.

Exams take place in dedicated facilities communicated at convenient time.

Exam is in English only.
