AIMS AND CONTENT

AIMS AND LEARNING OUTCOMES

The attendance and active participation in the proposed training activities (frontal lessons, exercises and educational visits) and individual study will allow the student to:

• correctly write the macroscopic balances of material and discuss them using appropriate vocabulary;
• apply the macroscopic balances of material (by mass and moles) to single unit operations typical of chemical engineering;
• identify possible simplifying assumptions in the framework of process problems which can be solved using material macroscopic balances;
• calculate the diagram (flow rates, concentration) describing a process scheme with a number of unit operations.

PREREQUISITES

For a successful learning basic knowledge of mathematics, chemistry and physics are required, but no formal propaedeuticity is provided.

TEACHING METHODS

The presentation of theoretical contents alternates with lessons with exercises carried out on the board by the teacher or in guided groups to encourage learning and discussion of specific examples of applications of process engineering. In order to bring students closer to the specifics of the course of study, educational visits will be made to the plants and testimonials will be invited. Class attendance is recommended.

Transversal skills in terms of communication skills and independent judgment will be acquired through the teamwork, a test developed in the classroom by consulting technical handbooks and a podcast production.

SYLLABUS/CONTENT

The program of the module includes the presentation and discussion of the following topics:

1. Introduction (10 hours)

Brief history of chemical engineering, main chemical-physical variables, lexicon and nomenclature. Notes on unitary operations and process schemes.

2.Macroscopic material balance (30 hours)

Macroscopic material balance by mass and moles (complete and simplified formulation);steady-state and transient conditions, in open and closed systems;

case studies with reactions where yield, kinetics or equilibrium are supposed;

freedom degree calculation in process plants;

trategy for the solution of process problems;

use of technical handbook as data sourcing.

3.      Educational visits to process engineering plants (15 hours)

4.      Meetings with testimonials (2 hours)

5.      Workshop for making a podcast (3 hours)

RECOMMENDED READING/BIBLIOGRAPHY

The teaching material used during the lessons will be available in the web classroom, as well as examples of final tests proposed in the previous years and a trace for their solution. The notes taken during the lessons and the material in the web classroom are sufficient for the preparation of the exam, but the following books are suggested as supporting and deepening texts:

- D.M. Himmelblau amd J.B. Riggs, Basic Principles and Calculations in Chemical Engineering, Prentice Hall Pearson Edication.

- M.C. Annesini, “Fenomeni di trasporto. Fondamenti e applicazioni”, Edizioni Hoepli.

- R. Mauri, Elementi di fenomeni di trasporto, Plus Pisa University Press.

- R.H. Perry, D.W. Green,“Perry’s chemical engineers’ handbook” VIII ed., Mc Graw Hill.

EXAM DESCRIPTION

The final test of the module consists in passing a written test for admission to the oral test. The written test consists of a problem to be solved in 2 hours answering to one or more specific questions and an open question related to the result discussion. The necessary data can be provided in the text or to be found on technical handbooks made available by the teacher, while it is not allowed the consultation of any other text.

Students will find examples of tests proposed in previous years with the related trace for the solutions on the web classroom. Some exam examples are carried out in detail in the classroom and the teacher is available for explanation agreeing appointment.

The written test can be held either in previous appeals or in the same appeal in which student intends to take the oral exam. The written test has no expiry limits, it can be repeated, but in this way the grade which is considered valid is the one obtained on the last written exam.

To access the oral exam students must have passed the written test with a minimum grade of 16/30 and the final grade will be the average between written and oral exam. The oral test can be repeated maintaining the grade obtained for the written test.

To access the oral exam students must have passed the written test with a minimum grade of 16/30 and the final grade will be the average between written and oral exam. The oral test can be repeated maintaining the grade obtained for the written test.

Three exam appeals for the ‘summer’ session will be available (June, July and September) and two appeals for the ‘winter’ session (January and February). The oral test can be held also during the teaching break provided by the Polytechnic School in Autumn and Spring. No extraordinary appeals will be granted outside the periods indicated by the polytechnic school, with the exception of students who have not included formative activities in the study plan current academic year.

ASSESSMENT METHODS

The written test concerns a problem which requires the solution of macroscopic material and/or energy balances applied at interface, single unit operation or plant scheme. In addition to the ability to correctly formulate and solve the problem, the applied methodology, the discussion of the assumed hypotheses and the written quality of exposition will be evaluated.

The oral exam includes questions concerning all the contents proposed during the lessons, asked in terms of theoretical questions or application problems. The examination aims to assess the specific skills acquired and, in particular, the ability to apply them combined together to face concrete case studies. The quality of the exposition, the correct use of technical terminology and critical reasoning ability will be also assessed.

FURTHER INFORMATION

For a successful learning, basic knowledge of mathematics, chemistry and physics is required, but no formal propaedeuticity is provided.

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 that, in compliance with the teaching objectives, take into account individual learning opportunities and provide suitable compensatory tools.
