Transfer in a Stirred Cell

In this example we reexamine the mass transfer in the system glycerol (l)-water (2)-acetone (3) considered in Example 8.7.1. A large amount of a glycerol-rich phase of bulk composition 

Using the same physical property data as in Example 8.7.1, calculate the fluxes 

SOLUTION With the Maxwell-Stefan diffusion coefficients and thermodynamic factors as given in Example 8.7.1, the matrix of Fick diffusivities [D] can be evaluated from Eqs. 4.2.12 using the average mole fractions with the following results  

The matrix of low flux mass transfer coefficients is found directly from Eqs. 8.4.31 or 

The first estimate of the diffusion fluxes is calculated from Eq. 9.3.35 with the correction factor matrix taken to be the identity matrix
