CHIM0071-3  Reduction of pollutants from combustion

Duration :  30h Th
Number of credits :  
Master in Electro-mechanical Engineering, Teaching Focus, 1st year3
Master in Electro-mechanical Engineering, professional focus in sustainable car technologies, 1st year3
Master in Electro-mechanical Engineering, Professional Focus (Management), 1st year3
Lecturer :  Angélique Léonard
Language(s) of instruction :  
French language
Organisation and examination :  
Teaching in the first semester, review in January
Course contents :  
This course deals with the atmospheric pollution in a wide way by approaching at the same time aspects connected to the production of pollutants and to their environmental impact (acid rains, global warming, production of tropospheric ozone) and aspects related to prevention (primary methods) or to the treatment of the pollution (secondary methods). The techniques of flue gases cleaning are presented for large installations of combustion as well as for vehicles.
The end of the course bends over the advanced technologies of electricity production from gasification of biomass or coal.
Main studied pollutants: carbon dioxide, carbon monoxide, nitrogen oxides, sulphur oxides, oxidized organic compounds, polycyclic aromatic hydrocarbons, soots and ashes.
Primary methods: modification of the energy mix, reduction of the quantity of consumed primary energy, fuel cleaning, optimization of the operating conditions , ...
Secondary methods: flue gas cleaning (desulfurization, denitrification, dust removal, CO2 capture, two-way and three-way catalytic converter).
The course is divided into five parts:
- The combustion - The atmospheric pollution and the role played by the combustion - Inventory of pollutants of the combustion: emission mechanisms and emitted quantities - Standards relative to air pollution - Techniques of reduction of the pollutants due to combustion
Learning outcomes of the course :  
At the end of the course, the student will be able
1) to show his understanding of the theoretical concepts seen in the course;
2) to explain the main environmental phenomena connected to atmospheric pollution (acid rains, ozone layer depletion, production of tropospheric ozone, the intensification of the greenhouse effect);
3) to realize the inventory of main pollutants of combustion, to explain their mechanisms of production, to describe their impact on the environment and to explain the allowing means either to prevent their emission, or to eliminate them from flue gases
4) to realize a calculation of flow and composition of flue gases during the combustion of a fossil fuel realized in excess of air including the determination of the required quantity of air as well as the check of the contents in sulphur and nitrogen oxides in comparison with the current regulation.
The first three points are the object of a detailed list of questions which will be communicated at the beginning of course.
Prerequisites and co-requisites/ Recommended optional programme components :  
The course relies on basic knowledge in chemistry, as taught in the courses of the bachelor in civil engineering or chemical sciences.
Planned learning activities and teaching methods :  
The course is based on 'ex-cathedra' lectures, one of them being devoted to the calculation of flue gas composition during combustion of fossil fuels.

The visit of an industrial site will be also organized.
Mode of delivery (face-to-face ; distance-learning) :  
Face-to-face lectures.
Recommended or required readings :  
Slides used during the lectures may be downloaded from eCampus.
Assessment methods and criteria :  
The examination contains an oral and written part.
For the oral part, every student receives two opened questions from a list communicated beforehand. The student has to show at the same time its knowledge and its understanding of the concepts, the technologies seen during the theoretical course.
The written part consists in an exercise aiming at determining the composition of flue gas during fossil fuel combustion. The use of a calculator is allowed.
Work placement(s) :  
Organizational remarks :  
The course is given during the first quadrimester, each some Thursday afternoon (13h30-16h30).
Precisions about the schedule will be given during the first course (18/09/2014).
Room: 1-/426 - B52 (Sart Tilman)
