|
|
| Duration : | 15h Th |

| Number of credits : |
|

| Lecturer : | Michel Crine |

Language(s) of instruction :
|
| French language |
|
Course contents :
|
| This course will cover energy aspects of unitary physical operations in which mass and heat transfers are strongly connected:
direct thermal contact between air and water (air conditioning, recovery of calories through gas scrubbing, etc.),
humidification or drying of air and drying of solids.
The course presents first mechanisms controling performance of these unit operations:
- Liquid-vapor equilibria: review of ideas of temperatures of humidity thermometer and adiabatic saturation, psychrometric diagrams.
- Kinetics of liquid-vapor transfer.
- Solid-liquid-vapor equilibria: different forms of water in a solid, isotherms of adsorption.
- Drying kinetics: different periods for drying.
The course presents then modeling of two types of unit operations:
- Modeling of direct thermal contacting between water and air: concept of the thermal and mass transfer units .
- Modeling of dryers: classification of different types of dryers. Heat and mass balances.

Learning outcomes of the course :
|
| At the end of the course, students will be able to apply the theoretical concepts and the analysis methodology of unit operations from the point of view of energetic consumption. They will be able to use this methodology to design and determine the size of a process, taking into account the energetic aspect of its functioning. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| "Génie chimique (opérations physiques unitaires et aspects non spécifiques des appareils)" (CHIM0083-2) (or a course with similar contents) should have been attended during previous years (or it should be attended the same year). |
|
Planned learning activities and teaching methods :
|
| The course is based on ex-cathedra lectures (15 h).
These lectures are dedicated to the detailed description of the fundamental concepts necessary for the analysis of the energetic aspects of unit operations. |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| Face-to-face |
|
Recommended or required readings :
|
| The course material is available on the eCampus website. |
|
Assessment methods and criteria :
|
| An oral exam is organized during the first session (January).
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 exam proceeds with closed reference books.
The examination in August/September (retakes) is organized in the same way as in June. |
|
Organizational remarks :
|
| The course is organized during the first quadrimester. |
