Content
Exergy
  •             Introduction to exergy
  •             Importance of exergy in Chemical Engineering
  •             Exergy in reaction and separation
Pumps and Compressors
  •             Pumps: Fundamentals
  •             Types of pumps and their specificities         
  •             Compressors: Fundamentals
  •             Types of compressors and their specificities.
  •             Multistage compressors and their benefit
Heat Exchangers
  • Conduction, convection. Solutions of conduction in 1D: multi-layer plate, multi-shell pipe, fins on plates and fins on pipes. Electrical analogy and thermal resistance.
  • Heat transfert coefficients. Laminar flows: case with constant heat flux density at the wall, case with constant wall temperature, thermally developed flow and thermal entry length. Correlations for turbulent flows.
  • Heat exchangers: co-current, couter-current, cross-current. LMTD (Logarithmic Mean Temperature Difference) method.
  • Epsilon-NTU (Number of Transfer Units) method   
Safety and Operation – invited speaker from industry
  •             HAZOP analysis
Safety valves - invited speaker from industry
Process simulation using ASPEN (practical classes in computer room)
Teaching methods
This course combines lectures in class, sessions of exercises in class, and exercises of simulation (computer) using Aspen +
This course addresses issues related to sustainable development and transition through the following activities:
  • Sessions dedicated to the role of exergy in determining if a chemical process is sustaible or not. Destruction of exergy will be discussed as a first step in determining sustainability.
Evaluation methods
Exam (theoretical and practical questions). The exam is divided in three parts related to 1) heat exchangers, 2) pump and compressors and 3) exergy analysis. The students have to pass the three parts to credit the course.
Exercises proposed during the course could contribute to the final mark.
The use of generative AI such as ChatGPT, Consensus, Perplexity, etc. is tolerated for the search for information or clarification of concepts but its use is prohibited for the elaboration of reports or any material which is part of the course evaluation by the teacher. The student must declare on their honor that the AIs were not used.
Other information
This course requires basic knowledge of hydrodynamics & transport phenomena, thermodynamics and applied mathematics.
