Toor-Stewart-Prober Formulation

Toor (1964) and Stewart and Prober (1964) did not use the method presented above they used the method described in Chapter 5. For the multicomponent penetration model, the following expression for the matrix of mass transfer coefficients is obtained (cf. Section 8.4.2)  [Pg.232]

Equation 8.4.24a serves as a starting point for computing the mass transfer coefficients [Pg.233]


Equations 5.1.6 represent a set of n - 1 coupled partial differential equations. Since the Fick matrix [ )] is a strong function of composition it is not always possible to obtain exact solutions to Eqs. 5.1.6 without recourse to numerical techniques. The basis of the method put forward by Toor and by Stewart and Prober is the assumption that c and [D] can be considered constant. (Actually, Toor worked with the generalized Fick s law formulation, whereas Stewart and Prober worked with the Maxwell-Stefan formulation. Toor et al. (1965) subsequently showed the two approaches to be equivalent.) With this assumption Eqs. 5.1.6 reduce to... [Pg.96]
