An introduction to the modeling and dimensioning of multiphase operations in chemical engineering. It is structured in three parts and 21 chapters, and includes numerous corrected exercises. The first part presents the generic elements. It includes an introduction to chemical engineering concepts and methodologies, a description of the multi-scale approach to estimating transfer, an analysis of possible couplings between interfacial transfer and reaction, and the fundamental equations describing multiphase flows. The second part focuses on operations involving a gas or liquid phase and a particulate solid. It covers characterization of the particulate solid, hydrodynamics and mass transfer in fixed and fluidized beds, and liquid-solid and gas-solid separation by settling, filtration, cycloning and centrifugation. The third part deals with operations involving at least two fluid phases. It addresses gas-liquid flow in pipelines, bubble, droplet, falling film, tray and packed columns, gas-liquid separation and three-phase reactors.

The book is aimed at bachelor's and master's students in chemical, environmental, food and process engineering, as well as practicing engineers.
