| Contents | 1. Material and energy balances in stoichiometric control reagent systems (combustion) 2. Reactive systems with thermodynamic control: Chemical equilibrium 3. Phase equilibria in multicomponent systems 4. Thermodynamic and kinetic principles underlying the operation of fuel cells |
| Reference texts | Notes from the teacher illustrated during the course. Matteo Maestri. Fundamentals of chemical processes. Principles of thermodynamics, kinetics and chemical reactoristics applied to the study of chemical processes. Publisher: Mc-Graw Hill, Year 2021, ISBN: 978-8-83-865536-4 |
| Educational objectives | This course aims to provide basic knowledge relating to the thermodynamics of reacting systems and multiphase-multicomponent equilibria necessary for a rational understanding of the chemical processes and unit operations that constitute them with reference to their use in applications of energy interest. At the end of the course the student must demonstrate: a) to have complete knowledge of the principles of thermodynamics and multiphase and multicomponent equilibria for the design and analysis of chemical processes and unit operations b) to be able to apply the above knowledge for the quantitative analysis of chemical processes through the resolution of problems concerning mass and energy balances, chemical equilibria of reacting systems and multicomponent and multiphase equilibria c) to be able to autonomously apply the knowledge object of the course in solving problems concerning chemical processes |
| Teaching methods | The course includes theoretical lessons, in which the concepts recalled in the program will be illustrated, and exercises in which calculations relating to chemical processes and phase equilibrium problems in multicomponent systems will be carried out. |
| Learning verification modality | Verification of learning includes a written exam, in which quantitative exercises relating to the practical part of the course will be carried out, and an oral exam concerning the concepts illustrated in the theoretical part of the course. Passing the written exam with a positive result (<= 18) is a mandatory requirement for admission to the oral exam. |
