L] and

chemical potentials of both components (solvent [[micro].

As described earlier in this article, the driving force of water absorption of water swellables is the

chemical potential difference between swellable elastomer and surrounding fluid.

1 indicates that the molecules of oil which belong to drops of different sizes have distinct

chemical potentials.

The Fischer-Tropsch process operates at elevated pressures; the ideal gas model for

chemical potential is not expected to be valid.

A corresponding defining inequality exists also for the

chemical potentials [mu], as we will discuss in the next subsection.

The correlation of the binary VLE data was performed using thermodynamic conditions at equilibrium where the

chemical potentials are equal.

In Equation (16) the residual

chemical potential [[mu].

To obtain the values shown in Table 4, we first predicted the Flory-Huggins interaction parameter between methanol and each polymer, and then, by using the relationship between the

chemical potentials of the liquid and the polymeric phase, we calculated the equilibrium concentration when solutions of 12 gol/l and 18.

Vrentas and Duda expressed a functional relation among the mutual diffusion coefficient,

chemical potentials and self-diffusion coefficients of a polymer/small molecule system by (30)

This was carried out by equating the

chemical potentials of C[O.

Variations of the

chemical potentials of the constituents with composition during sorption have been calculated from the Gibbs-Duhem equation:

Mathematical Expression Omitted], [Mathematical Expression Omitted] =

Chemical potentials of a component i in liquid and vapor phases, respectively, J/kmol.
