Training objectives
The main objective of this course is to introduce the Pinch Technology Approach (principles, theory, fundamental concepts and applications). This technique is the most widely used for designing optimized efficient energy systems by saving Energy and both investment and operating costs.

Learning objectives
- Distinguish between exergy, entropy and energy
- Distinguish between efficient and inefficient energy system designs
- Understand the efficient use of energy and the reduction of environmental effects
- Understand the economic potential to improve energy efficiency
- Distinguish between renewable and non-renewable energy resources in an environmental context
- Save Energy and both investment and operating costs by heat recovery in process design
- Understand the Methodology for minimum energy consumption of processes (PINCH)
- Design thermodynamic efficient processes (precisely : Efficient Heat Exchangers Networks)

Learning context
This course introduces the students into the PINCH Technology approach for designing thermodynamic efficient processes. It will place all the students past achievements (from laws of thermodynamics, thermodynamic cycles and heat transfer) in an objective of designing energy efficient Heat Exchangers Future Networks with minimum economic and energy costs.
