The effects of electric fields upon fluid motion have found several applications in chemical engineering. The earliest and best-known is that upon the coalescence of particulates in the gas phase. Within the past 25 years, the effects of electric fields upon liquid-liquid systems have been increasingly the focus of research. Conventionally, efficient liquid-liquid mass transfer requires mechanical agitation in order to reduce droplet size and increase specific interfacial area. However, excessive agitation can produce drops so small that they form stable emulsions which are hard to coalesce; also, the mass transfer coefficients are usually very small for small drops because surface forces prevent circulation and they behave like rigid spheres.
