OVERVIEW

The course will provide the basic knowledge necessary for understanding the operation of the main separation (humidification, absorption, drying, distillation, etc.).

AIMS AND CONTENT

LEARNING OUTCOMES

The module aims to provide the basic theoretical tools for the design of the separation unit operations of a process industry plant, from theoretical development to field implementation. The basic criteria for selection, design and operation of some typical separation columns will also be addressed.

AIMS AND LEARNING OUTCOMES

Basic knowledge  for the analysis of systems through the formulation of conservation equations of matter and energy. Basic knowledge for the design of the main equipment (continuous and discontinuous contact) used in physical separations (absorption, distillation, humidification, drying, concentration by evaporation). Fundamental principles of the separation operation for liquid-liquid extraction. 
At the end of the course, the student will have acquired the knowledge to design (in genera terms) the main equipment of the chemical industry. In particular, the student will be able to:
a) know the principles of mass transport phenomena between heterogeneous fluid phases
b) know the operating principles of the main unit operations of the chemical process industry (absorption, distillation, humidification, drying ...)
c) apply the knowledge acquired to: a) design the most important equipment, b) perform troubleshouting analysis

TEACHING METHODS

The course corresponds to 5 CFU (university credits), equivalent to 125 hours of actual student commitment, distributed as follows: 40 hours of lectures (frontal teaching) and 85 hours of personal study (self-learning). During the year, some numerical exercises will be conducted in class and homework assignments will be given to be completed at home, which will help students acquire the concepts covered in the lectures.

The teaching materials distributed by the instructor will be made available on AulaWeb.

SYLLABUS/CONTENT

Tools and methodologies for process analysis. Basic knowledge on material transport phenomena, highlighting their key role in the behavior of the most common unit operations. Basic concepts for understanding and describing the phenomena that regulate the main unit operations for physical separation (absorption, humidification, distillation). Introduction to the operations of separation by concentration (by evaporation). The most important process variables will be introduced for each unit operation, highlighting their role in affectingthe performance of the equipment.

EXAMS

EXAM DESCRIPTION

The exam is oral: the teacher asks questions, typical of an oral exam. Additional information:

• the dates are available on-line;
• online registration is mandatory and must be done from the webpage: https://servizionline.unige.it/studenti/esami/prenotazione; 
• the classroom chosen for the exam and the start time will be communicated by e-mail sent via aul@web.

The grade obtained in the teaching will be the average of the marks given in the two modules in which the teaching is divided.

For students with disabilities or DSA, please refer to the Further Information section.

Only in urgent cases can the exam be conducted online, in accordance with the regulations issued by the University.

ASSESSMENT METHODS

The student must demonstrate knowledge on:

• the formulation of macroscopic material and energy balances;
• the main models for describing ideal liquid-vapor phase equilibria;
• the basics of mass transport phenomena;
• the operating principles of the most important physical separation processes (absorption, distillation, humidification, liquid-liquid extraction).

FURTHER INFORMATION

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Sergio Di Domizio (sergio.didomizio@unige.it), the Department’s disability liaison.
