Description

Different types of ideal chemical reactors will be presented in batch and flowing systems : Continuous stirred reactor, plug flow reactor with and without axial dispersion. The residence time distribution in these ideal reactors will be presented as well as the Peclet number for real plug flow reactor. The combination of ideal reactors will also be developped. Non ideal reactors and segregation model will be presented. Implementation of kinetics laws in the different kind of reactor will described with mass balance in each case allonwing to determine conversions, selectivities and yield depending on the type of reactor choosen.Different types of ideal chemical reactors will be presented in batch and flowing systems : Continuous stirred reactor, plug flow reactor with and without axial dispersion.

Reactors are generally the heart of a chemical process. Their design depends on many parameters of the reaction (phase, kinetic, use of a catalyst, thermodynamic...). The aim of this course is to be able to choose and design a type of chemical reactor for a given reaction.- be familiar with the different types of ideal reactors - associate a real reactor to a combination of ideal reactors from residence time distribution measurement - implement kinetic laws in a flowing ideal reactor to predict conversions, selectivities and yields - design of a chemical reactor to optimize a given reaction knowing the kinetics of the reactions (type of reactor, volume, inlet flows...)
