Multiphase Reactors in Fine Chemistry: Simplifying Design for Students and Practicing Engineers

Here, the basic aspects of multiphase reactions, the importance of transport parameters vis–a–vis kinetics are clearly brought out, backed by a discussion of the principles of similarity in scale–up. The book treats new reactors in depth, in particular the ventury loop reactor and monolithic reactors, while also covering the problems encountered in retrofitting existing reactors for new reaction duties. Very simple yet theoretically sound design procedures are given, which require minimum time but yield reliable results, supplemented by rapid optimization tools in the form of Excel worksheets. A number of solved examples are included for each reactor type presented. INDICE: INTRODUCTION TO SIMPLIFIED DESIGN PHILOSOPHY. MULTIPHASE REACTORS: BASIS OF DESIGN AND SCALE–UP.
