Course contents :
|
| This course presents concept of unit operations, based on heat and mass balance equations. The applications to the following physical unit operations are described:
- Gas-liquid absorption-desorption: Different configurations of gas-liquid contactors (co- and counter-current, operating line). Stage contactor (theoretical stage, plate efficiency), continuous contactor (number of transfer units, height of a transfer unit). Relation between number of theoretical stages and number of transfer units.
- Distillation: Different configurations: mono- and multi-stage distillation, continuous and discontinuous. Thermodynamic liquid-vapour equilibrium. Coupling between heat and mass balance. Lewis-Sorel equation, McCabe-Thiele and Pochan-Savarit methods.
- Liquid-liquid extraction: Different configuration of mono- and multistage mixer-settler. Liquid-liquid thermodynamic equilibrium. Use of ternary phase diagram. Mass transfer between phases, Concept of theoretical stage. McCabe-Thiele method. Plate efficiency.
- Heat exchangers: Different configurations. Local heat transfer kinetics. Counter-current heat exchanger. Number of (thermal) transfer units. Efficiency of a heat exchanger. Design methods: LMTD and NTU-epsilon.

Learning outcomes of the course :
|
| At the end of the course, students will be able to apply theoretical concepts and the analysis methodology of physical unit operations. They will be able to use this methodology to design and determine the size of physical unit operations.
They will be able to be rigorous and discriminating in the analysis of available experimental data and the identification of rate limiting steps and to include them in simulation tools.
Exercise and laboratory sessions in small groups will help the students to develop more transversal skills as team-working, numerical problem resolution, critical analysis of experimental data and assessment of the validity of a theoretical approach. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| The course "Introduction au génie chimique" (CHIM0022-2) or a similar course of "Transport phenomena" and the course "Applied Chemical Thermodynamics" (CHIM0009-1)(or courses with similar contents) should have been attended previously or they should be attended the same year. |
|
Planned learning activities and teaching methods :
|
| The course is based on ex-cathedra lectures (45 h) and practical courses (45 h) including exercises and laboratory sessions.
The ex-cathedra lectures are dedicated to the presentation of fundamental concepts necessary to the design and the performance determination of physical unit operations.
Practical courses include exercises sessions during which students learn how to solve problems related to the design of physical unit operations.
During laboratory sessions, students work in (small) team. They have the opportunity to get familiar with different types of laboratory scale equipments representative of unit operations described in the theoretical part of the course and applied during the exercises sessions.
Participation to laboratory sessions is mandatory. Each of these sessions has to be prepared by carefully reading the corresponding laboratory notes. |

Mode of delivery (face-to-face ; distance-learning) :
|
| Face-to-face
|
|
Recommended or required readings :
|
| The theoretical course material is available on the eCampus website.
Additional information (exercises and laboratory notes) are also available on the eCampus website at the beginning of the year. |
|
Assessment methods and criteria :
|
| An interrogation is organized during the first session (January). It involves an oral part and a written part, concerning theory and exercises, respectively
For the oral examination, students prepare answers on paper which they will then explain and develop orally. Evaluation relies essentially on the understanding of concepts and relationships between them rather on the capacity to make restitution. The examination proceeds with closed reference books and without calculator.
The written part consists in exercises to solve, which are similar to those presented during exercise sessions. Students can use the theory notes and a calculator. Exercise notes and formulas' lists are not accepted.
Students with marks greater or equal to 10/20 are exempted from the final exam in June. Marks less than 10/20 are discarded.
An interrogation is organized in June for non exempted students. It involves an oral part and a written part, concerning theory and exercises, respectively. The exam in June is organized in the same way as in January.
Moreover, a report of the laboratory sessions must be provided by the students within 30 days after these sessions. This report must present the obtained experimental results, their critical analysis as well as answers to the questions presented in the laboratory notes.
The global mark is a weighted average of the marks obtained at the oral test (60 %), the written test (20 %) and the laboratory report (20 %).
The second session exam is organized in the same way as in June. The mark obtained for the laboratory report is maintained. |
