OVERVIEW

The course provides tools and methods for the definition of dynamic models of the most common chemical reactors, analysis of the dynamic behaviour  during all phases of operation and control strategies.

AIMS AND CONTENT

LEARNING OUTCOMES

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.

LEARNING OUTCOMES (FURTHER INFO)

Applying knowledge and skills

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.

TEACHING METHODS

Lectures with the help of slides provided by the teacher, numerical exercises.
