ABSTRACT
I. INTRODUCTION A. Background Phase coalescence may be defined as the aggregation of dispersed droplets that are suspended in another immiscible or partially miscible liquid, to form a heterogeneous dense packed zone at the main interface between the two bulk liquid phases. The coalescence phenomenon is associated with and important to some processing industrial operations, e.g., in the liquid-liquid extraction process. Indeed, liquid-liquid separation is not only restricted to extraction processes; it is also of considerable impor tance in effluent treatment plants and in any processes where liquid-liquid dispersions are present.
