16.7.4 Mixer Mass-Transfer Coefficients

Determination of mass-transfer coefficients in liquid-liquid extraction is fraught with more than the usual amount of uncertainty. Equation (16-80b) shows that the individual coefficients for both dispersed and continuous phases are required. Any uncertainties in the estimation of diffusivities will propagate error in the mass-transfer coefficients. For the typical +20% error in liquid diffusivity, the result is a +10% to 15% error in the mass-transfer coefficient (Slater, 1994). Also, because effects of coalescence, drop breakage, and time dependence are not well understood, they are usually ignored, which increases the potential error. The concentration of surface active agents and of small solids at ...
