Multiphase contact apparatuses are widely used in the chemical and biocatalytic process industry in which a gaseous reactant has to be supplied. The achievement of high mass transfer rates with regard to process efficiency is mostly challenging. In this work a novel aeration technique based on fine bubbles with diameters smaller 100 µm is experimentally analyzed, providing large interfacial areas for the mass transfer process. The experiments show the benefit of using fine bubbles by reaching significantly higher mass transfer rates compared to conventional aeration. Especially stirred tank reactors prove to be most suitable for fine bubble aeration. Finally, models are developed, describing the mass transfer characteristics at microscales.

The book summarises the outcom of a priority research programme: 'Analysis, Modelling and Computation of Multiphase Flows'. The results of 24 individual research projects are presented. The main objective of the research programme was to provide a better understanding of the physical basis for multiphase gas-liquid flows as they are found in numerous chemical and biochemical reactors. The research comprises steady and unsteady multiphase flows in three frequently found reactor configurations, namely bubble columns without interiors, airlift loop reactors, and aerated stirred vessels. For this purpose new and improved measurement techniques were developed. From the resulting knowledge and data, new and refined models for describing the underlying physical processes were developed, which were used for the establishment and improvement of analytic as well as numerical methods for predicting multiphase reactors. Thereby, the development, lay-out and scale-up of such processes should be possible on a more reliable basis.

This monograph is a highly technical analysis of the interaction of two phases in controlled experiments. By using a perforated plate and stirred tank, Dr Azbel has conducted experiments involving flow, mass bubbling, mass transfer during bubbling and in a liquid-solid system and the calculation of bubbling reactors for the two-phase oxidation reaction. The last chapter investigates the design of a reactor for microbiological processes. The behaviour of bubbles is a unifying theme of this book. From an explanation of the fundamentals of bubbles formation at a single orifice, Dr Azbel goes on to set up equations for bubble motion, bubble size, bubble-size distribution and pressure drop across a perforated plate. His treatment of bubbles is expanded in later chapters to include mass transfer in the dispersion of solid particles in a liquid and mass transfer accompanied by chemical reactions in a bubble dispersion system.

The phenomenon of "mass transfer with chemical reaction" takes place whenever one phase is brought into contact with one or more other phases not in chemical equilibrium with it. This phenomenon has industrial, biological and physiological importance. In chemical process engineering, it is encountered in both separ ation processes and reaction engineering. In some cases, a chemical reaction may deliberately be employed for speeding up the rate of mass transfer and/or for increasing the capacity of the solvent; in other cases the multiphase reaction system is a part of the process with the specific aim of product formation. Finally, in some cases, for instance "distillation with chemical reaction," both objectives are involved. Although the subject is clearly a chemical engineering undertakin, it requires often a good understanding of other subjects, such as chemistry and fluid mechanics etc., leading to publications in diversified areas. On the other har.d, the subject has always been a major field and one of the most fruitful for chemical engineers."

The field of multiphase flows has grown by leaps and bounds in the last thirty years and is now regarded as a major discipline. Engineering applications, products and processes with particles, bubbles and drops have consistently grown in number and importance. An increasing number of conferences, scientific fora and archived journals are dedicated to the dissemination of information on flow, heat and mass transfer of fluids with particles, bubbles and drops. Numerical computations and “thought experiments” have supplemented most physical experiments and a great deal of the product design and testing processes. The literature on computational fluid dynamics with particles, bubbles and drops has grown at an exponential rate, giving rise to new results, theories and better understanding of the transport processes with particles, bubbles and drops. This book captures and summarizes all these advances in a unified, succinct and pedagogical way.
