Chemical Kinetics and Reactor Design

Chemical reactors are the core features of a chemical process. This chapter aims to present some aspects of reactor design with the use of the UniSim design simulator and the Excel spreadsheet. For this purpose, the various reactions types are introduced and then the common reactors are presented listing the types of reactions used in each reactor type. Additionally, a short review is provided on the simulation of non-ideal reactors using the UniSim design simulation software, and some general comments are also given on multiscale modeling. Hands-on problems are presented for showing the step-by-step solution with the UniSim design and the Excel spreadsheet. Kinetics studies of biochemical reactions are also provided. The processing of waste, biomass and biological materials with cells, enzymes, or antibodies consists the core of the biochemical reaction engineering. Finally, a review of safety in reactor with a case study of an industrial incident is presented.
