Abstract
A proposed, method of Joffe for determining fugacity coefficients of gases In binary mixtures is presented. The method is evaluated by calculating 320 pairs of fugacity coefficients and comparing the results with experimental data and with values calculated by the method of Pitzer.
Joffe derived the expression for fugacity coefficients by employing the technique of Gamson and Watson. The expression is based on the three-parameter corresponding states principle as previously presented by Pitzer and a proposed definition of the pseudocritical properties.
The method of Pitzer and the proposed method of Joffe both require the same data.
This study is based on the experimental data for five binary mixtures: methane - carbon dioxide, methane - ethane, n-butane - carbon dioxide, methane - n-pentane, and methane - n-butane.
The proposed method has been found to produce an overall average deviation of 10.5 % for 640 data points as compared to 11.2 % found for the same data points by the method of Pitzer.
