Objectives

The course is focused on the study of Mass Transfer phenomena. The students should acquire here sound basic knowledge on: the physical and the mathematical description of the mass transfer mechanisms (diffusion and convection), the transport of a solute between phases in contact, the concept of individual and global mass transfer resistances, establishing mass balances for different cases/geometries in steady state and transient conditions, definition of appropriate boundary conditions, application of the acquired concepts to the design of some mass transfer equipment and developing the skill of problem solving.

Program

1 - Introduction
-Mass transfer mechanisms: diffusion and convection
-Fick’s first law
2 - Mass transfer between phases
- Convection law
- Distributed solute between fluids in contact
- Interfacial transfer
- Correlations to determine coefficients of mass transfer
3 - Generalization of the Fick Rate equation
4 - Transient Diffusion
- Fick’s second law
- Diffusion in a half-space
- Diffusion limited by a surface impermeable to solute
- Solute penetration distance
- Surface renewal theory
5- Mass transfer in simple unit operation equipment
- Cell of mass transfer with perfect mix in each of the phases
6- Design and operation of packed towers
7- Introduction to mass transfer with chemical reaction
8-Introduction to simultaneous heat and mass transfer

Teaching methods and learning activities

The theoretical concepts and mathematical description are given in the first two theoretical/practical hours of each week to the whole course during the whole semester. Some illustrative problems are also solved in these classes. An additional class (theoretical-practical class) of 1.5 hours per week is devoted to discuss with the students the solution of problems (available at the beginning of the semester) solved by them. In these classes especial attention is devoted to the improvement of students' problem solving ability.

Eligibility for exams

Students have to do the following assignment to be admitted to exams: a text about one of the themes and solve 6 problems.
Students, who attended to this course in the previous years, can either do the assignment/problem solving, or just the final exam.

Calculation formula of final grade

Final Mark: FM
FM= 0,40 x CA + 0,60 x FE

CA- Continuous Assessment- a text about one of the themes (1 value) and solve 6 problems (7 values).
FE- Final exam

Students have to reach a minimum grade of 8 out 20 in the final exam.

Examinations or Special Assignments
