OVERVIEW

The course aims to provide students with the design tools necessary for the dimensioning of the main unit operations according to the main technical/economic optimization criteria.

AIMS AND CONTENT

AIMS AND LEARNING OUTCOMES

Attendance and participation in the proposed training activities (lectures, exercises and numerical exercises) and individual study will allow the student to acquire:
- design criteria and optimization of heat exchange networks for energy integration; the operating principles and design criteria for solid-liquid extraction and extraction with supercritical fluids; operating principles and design criteria for an adsorption/desorption column; understanding and reading process diagrams.
- be able to choose and use the most appropriate criteria for the design and analysis of the equipment covered by the course.
- know how to set up the equipment project in relation to the system in question, in order to achieve the design objective with the tools and time available; in running the plants, knowing how to interact with the equipment, through the set of process parameters, to achieve the desired operating conditions.
-refine the technical language concerning unit operations and heat exchange networks and become aware of the existence of specific communication protocols.
-know how to apply the acquired knowledge to different contexts from those presented during the course, and deepen the topics covered, specializing them to the specific topic under examination.

TEACHING METHODS

The teaching includes about 60% of methodological and theoretical lessons in the classroom, about 40% of calculative exercises in the classroom.

Working students and students with DSA disability or other special educational needs certification are advised to contact the teacher at the beginning of the course to agree on teaching and exam methods which, in compliance with the teaching objectives, take into account individual ways of learning.

EXAMS

EXAM DESCRIPTION

The achievement of the teaching objectives is certified through an oral exam of about 50 minutes to verify the ability of the design elements.

Excellence (30/30 cum laude) is achieved by demonstrating the ability to master the subject, being able to use the concepts learned and apply them to different types of problems than those discussed in the classroom.

ASSESSMENT METHODS

Details on how to prepare for the exam and on the degree of detail of each topic will be given during the lessons. The oral exam includes questions regarding the underlying theory and the sizing criteria of unit operations. The quality of the presentation, the correct use of technical terminology and the ability to critical reasoning will also be assessed.

The evaluation in the final exam will take into account the following criteria:

a) knowledge and ability to solve the main problems that require the application of expressed concepts;

b) knowledge of the basic hypotheses;

c) ability to extend the application of basic problem solving concepts to new applications,

d) language properties with particular reference to the specific terminology of the discipline.

The exam test will be evaluated as sufficient when the student is able to set up the design of the unit operation, when he demonstrates sufficient knowledge of the lexicon of the subject. The student who projects correctly, who has full and prompt perception of the effects of the variables on the project and who shows mastery of the vocabulary of the subject is evaluated as excellent.
