Abstract
Fugacity and activity coefficients have been calculated by a combination of analytical and graphical methods for the methane-carbon dioxide system at 100° F. for pressures up to 680 atmospheres.
Four mixtures of the two gases, methane and carbon dioxide, and the pure gases themselves were used in the calculations according to the adaptation and interpertation of the Redlich and Kwong equation of state as set forth by H.C. Van Ness (1).
The results of this thesis seem to substantiate H.C. Van Ness's paper as a convenient and accurate method of calculating thermodynamic properties of gases from experimental compressibility-factor data. Since the fugacity and activity coefficients for the methane-carbon dioxide system at 100° F. and for pressures up to 680 atmospheres have not been calculated before by any other method, the results can not be directly compared. However, since the calculated results are based on experimental data for this particular system, the results should be sufficiently accurate to serve as a standard of comparison for other empirical methods which use critical constants and generalized charts such as those of J. Joffe (6), W.C. Edmister (7), and O. Redlich (8).
