Abstract

A theoretical Monte-Carlo simulation model recently developed (Zeitlin, 1971; Zeitlin and Tavlarides, 1972b), which accounts for complex fluid-fluid interactions and dynamic effects in a fully baffled turbulently agitated dispersed phase vessel, is extended to include extraction between two liquid phases. With a limited amount of available experimental data, the model is employed to determine area-free mass transfer coefficients as a function of agitation rates for batch extraction of a chemically pure dispersed phase into the continuous phase. These transfer coefficients are then used in conjunction with the model to predict transient concentrations in the continuous phase. The model is employed to predict transfer coefficients and determine transient concentrations for batch extraction of a third component, from the continuous phase to the dispersed phase. The ability of the model to predict extraction rates is also demonstrated by prediction of equilibrium continuous phase concentrations as a function of flow rate for transfer between two phases of a flow system.
