The course provides tools and methods for the modeling of the dynamic behavior and control of chemical reactors, with particular reference to safe start-up and shut-down. The course provides tools and methods for the acquisition, processing and extracting information from time series process data.
Students will be able to define operating conditions for continuous and batch chemical reactors and to evaluate the possible start-up and operation problems. Students will be able to analyze process data and / or operating databases and to extract information for identifying faults or management issues. Students will be able to design pilot-scale experimental campaigns or simulation campaigns (with different types of models) for the study of the dynamics of chemical reactors.
Lectures with the help of slides provided by the teacher.

Written test (multiple choice questions), written exercise (carried out in group, on reactors simulation or data analysis tasks) and oral examination (discussion of the written exercise).
Written test: questions about theory and definitions.
It is used to evaluate the ability of the student to discriminate between different dynamic models, to evaluate stability, to know main controllers properties, to know the principal design crieria to prevent runaway and for safe start-up and shut-down of chemical reactors
Written exercise: a real problem about a pilot or lab-scale reactor (with some experimental data) is posed and must be solved in team.
It is used to evaluate the ability of the students to design pilot-scale experimental campaigns or simulation campaigns (with different types of models) for the study of the dynamics of chemical reactors.
Oral examination: questions about the written exercise
It is used to evaluate the contribute of each student inside the team work and about the application of theory.
