Study Programmes 2016-2017
MECA0046-1  
Heat exchangers : networks and rational use of energy
Duration :
15h Th, 5h Pr, 20h Proj.
Number of credits :
Master in electro-mechanical engineering (120 ECTS)2
Lecturer :
Marie-Noëlle Dumont
Language(s) of instruction :
French language
Organisation and examination :
Teaching in the second semester
Units courses prerequisite and corequisite :
Prerequisite or corequisite units are presented within each program
Learning unit contents :
The first section of the course addresses the analysis of energy supply and demand for chemical processes, and its representation in the form of composite curves. This leads to a second chapter, where the pinch design method for heat exchanger networks is developed. Finally we discuss the selection of utilities and energy carriers and their integration in a site wide energy system.
Learning outcomes of the learning unit :
This course aims to develop skills in performance analysis of heat exchanger networks, as well as in sysnthesis and design of energy systems.
After completing the course, a student should be able to draw composite curves to represent the energy supply and demand of a process, and to interpret them. He should be able to identify on that basis the expected efficiency of several energy saving technologies : combustion air preheat , oxygen enrichment, limitation of excess air, change of pressure level in condensers and boilers, selection of heat pumps or alternate recfrigeration cycles, integration of heat and power cycles.
Finally, starting with composite curves, he should be able to design an efficient heat exchanger network (matching streams that have to exchange heat, and deciding the amount of heat transfer), the goal being to maximize the energy recovery and to reduce the energy requirement of a process.
Prerequisite knowledge and skills :
Introduction to applied thermodynamics
Basic notions about heat exchangers, combustion, engine cycles and refrigeration
Planned learning activities and teaching methods :
During the formal course, theoretical basis are exposed and illustrated by simple examples. Students must also complete one individual assignments : design of a heat exchanger network allowing to maximize the energy recovery of a process, knowing its energy requirement (power required and temperature level)
Mode of delivery (face-to-face ; distance-learning) :
6 x 2 hrs courses individual applications, graded on the basis of  written reports.
Recommended or required readings :
Copy of all presentations Course documents available on eCampus
Assessment methods and criteria :
written report is graded. Oral examination on request.
