Mass transfer and liquid-liquid dispersion in agitated vessels

The effects of impeller type, speed, size, and location, and of liquid properties on the degree of mixing of two immiscible liquids in a baffled vessel are examined. A correlation of droplet size and continuous phase mass transfer coefficients in agitated vessels with operating variables and physical properties in liquid-liquid systems are investigated. In correlating mass transfer coefficients, a realistic mechanism was developed, involving periodically varying rates of surface renewal associated with droplet circulation through varying degrees of turbulence around the agitated vessel.
