Summary

This chapter addresses both the fundamental and practical aspects of liquid–liquid dispersion and coalescence, as well as application of the current state of knowledge to a variety of processes. The major emphasis is on turbulent stirred tank contactors, but other flow regimes and devices are also considered. Terms commonly used with the technology are defined. Dispersion and correlations for mean drop size and drop size distribution are described by reference to dilute systems. A basis for the analysis of coalescence is described by reference to systems with low dispersed phase concentration. A brief overview and survey of Population Balance methods follows. Since concentrated dispersions are often found in practice, the application of dilute and low concentration system technology and its limitations are addressed. Many related phenomena such as drop suspension, phase inversion and practices for forming dispersions are also discussed. Concluding sections include equipment that is commonly used, recommended scale-up practices and industrial examples.
