Wong and Sandler

Wong and Sandler [45] used the Helmholtz excess energy to develop the following mixing rule, that satisfies the second virial restriction ... [Pg.45]

Wong and Sandler (1992) have developed a mixing rule that combines an EOS with a free-energy model but produces the desired EOS behavior at both low and high densities without being density dependent, uses the existing table of parameters, allows extrapolation over wide ranges of temperature and pressure, and provides a... [Pg.50]

The original version of the Wong-Sandler mixing rule (Wong and Sandler 1992) uses the last equality of eqn. (4.3.1) as one of the restrictions on the parameters together with the combining rule... [Pg.51]

HE Helmholtz tree-energy departure function (from ideal gas behavior) for the Peng-Robinson equation at a given temperature, pressure, and composition is (Wong and Sandler 1992)... [Pg.112]

Because the excess Helmholtz free energy is closely related to this departure term (see Wong and Sandler 1992 for details) the same C term appears in the excess Helmholtz free-energy term obtained from the PR EOS. [Pg.112]

In the method of Wong and Sandler [20, 21], mixing rules are developed for a and b to satisfy two conditions ... [Pg.350]

Under different assumptions, Wong and Sandler [9] used the Redlich-Kwong equation with the mixing rule (6.5.4) to obtain a quadratic rule,... [Pg.249]

To obtain the unlike parameters, Wong and Sandler chose these combining rules. [Pg.249]

Wong and Sandler has shown that the following mixing rule does satisfy the second virial coefficient equation ... [Pg.1434]

Wong and Sandler followed a different approach by matching the Helmholtz function at infinite pressure from the cubic equation of state and from an activity coefficient model. This approach ensures consistency with statistical mechanics requirements that the second virial coefficient of a mixture has a quadratic dependence on composition. For the case of the Peng-Robinson equation of state, the Wong-Sandler mixing rules are ... [Pg.63]

The Wong and Sandler mixing rules used the modified Peng-Robinson or any other cubic equation of state and permit the use of tabulated G such as the DECHEMA Data Series. The mixing rules are comprised of the right-hand side of eq 5.17 with the combining rule... [Pg.105]

To satisfy Eq. (56), (Wong and Sandler, 1992) decided to revisit the Huron-Vidal mixing rules. Since they made use of the infinite pressure as the reference pressure, like Huron and Vidal, they obtained ... [Pg.92]
