Course contents :
|
| The first part of the course deals with the analysis of supply and demand for energy in a chemical process, and its representation in the form of compound curves.
It leads to the second part of the course develops that the design method of exchange systems based on pinch points compound curves.
Finally, the choice of utilities and their integration in the energy system of a site is briefly discussed.
The course will also deal with the introduction to the optimization of systems: an introduction to the parametric identification, measurement processing, validation.
It will continue with the dynamic modeling: formulation, analysis of degrees of freedom, introduction to process control. |

Learning outcomes of the course :
|
| The course aims to develop skills in analyzing the performance of a network of heat exchangers, as well as synthesis and design of these systems.
The student must be able to represent in the form of compound curves the thermal energy requirements of a process, and interpret these curves. It must be able to identify on this basis the potential use of technology to save energy: preheat combustion air, oxygen enrichment, limiting the excess air pressure change in boilers and condensers, use of heat pumps, refrigeration cycles, motor integration cycles (CHP).
Finally, the student, on the basis of curves, will be able to realise the synthesis of a network of efficient heat exchangers (choice of fluids that are exchanging heat exchange and quantities), and to maximize energy recovery by train exchange.
The course will enable students to acquire the necessary use of modern software static and dynamic simulation of large chemical systems knowledge. The dynamic part of this course is to complete the presentation of the basic concepts of dynamics and control of linear systems, covered in courses tray, allowing students to use software based on rigorous nonlinear models in applications practical process control, performance monitoring and optimization of chemical processes integrated. |
