A.A. 2024/2025
Obiettivi formativi
The aim of the course is to give students all the possible tools to be able to evaluate the type of reactor that is best for the chemical process being studied. Process optimization and basic cost evaluation will be taken into account.
The students will undertake numerical calculations solved either manually or with computational tools, to solve practically relevant examples.

Risultati apprendimento attesi
At the end of the course students will be able to manage simple reactions from the chemical engineering point of view, evaluating the chemical kinetics and sizing the ideal reactor to carry out the chemical reaction to the study.
The students should be able to solve practical examples and exercises either manually or through computationally implemented scripts on the following topics:
- Ideal batch reactor
- Ideal Plug flow continuous reactor
- Ideal Continuously stirred tank reactor
- Non ideal mixing
- Non ideal heat transfer
- Advanced chemical kinetics
- Mass and energy balances on single equipment and sections of the plant.

Mass and energy balances
Homogeneous and heterogeneous chemical kinetics
Study and design of batch reactors
Study and design of continuous reactors (PFR and CSTR) Reactors for biphasic and triphasic kinetics.
Optimization of times, sizes, and costs of chemical reactors
Prof. Rossetti
The students will be guided through a base introduction on the numerical methods needed to solve simple or advanced kinetic modelling and on the best ways to express kinetic rate equations for use in the design equations of ideal reactors.
Numerical methods will be introduced with the basic algorithm, followed by exercises, to be solved either manually or with the aid of Excel/Matlab/Phyton scripts. Basic understanding of the meaning and implementation modes of preconstructed scripts will be required to all students. Those aiming to become expert users will be guided (on request) to the development of an own-written script.
Correlated to the fundamental part on applied kinetics and reactors, numerical examples will be given in order to gain a practical insight into the reactor design activity (ideal batch reactor, continuous PFR and CSTR reactors).
Introductory concepts will be given on the issues raising with non ideal reactors. Computational fluid dynamics (CFD) will be introduced for these general concepts, with examples on reacting media in continuous flow reactors. COMSOL Multiphysics will be used as computational tool.
Finally, AI implementations have proven to dramatically reduce design and experimental efforts by enabling laboratory automation, predicting bioactivities of new drugs, suggesting synthetic routes to complex target molecules, predicting properties of materials and new molecules, optimizing reaction conditions, select the most appropriate plant configuration among thousands and discriminating among thousands of scenarios during fault, risks or lifecycle assessments. The potential and best practices for these emerging technologies will be introduced to the students with a comparison between different approaches of Machine Learning in cyber-chemical systems.

Metodi didattici
The course is taught entirely in English.
The educational approach involves a combination of traditional classroom lectures and computational calculations. During the lectures, the teacher uses a projector to display PowerPoint slides (PPT) on the screen or the classroom's whiteboard. This allows students to visually follow along and interact with the material.
Furthermore, students will engage in practical tutorials specifically focused on developing numerical methods for the solution of sizing and rating problems on chemical reactors. Part of the lectures will be taken in the informatic lab.

Modalità di verifica dell’apprendimento e criteri di valutazione
Il corso include un esame scritto con un esercizio e domande teoriche.
Sarà valutata la capacità dello studente di dimensionare un reattore chimico in condizioni operative reali. Inoltre, sarà valutata anche la capacità dello studente di identificare il tipo di reattore più adatto per diverse condizioni in cui deve essere condotta una reazione chimica.
Agli studenti verrà chiesto di descrivere i metodi numerici più appropriati per la risoluzione di un problema di modellazione cinetica o un caso di dimensionamento di un reattore.
