Abstract: This work presents the current status on the development of a natural gas supercompressibilily factor correlation. The equation of state developed in this work will potentially replace the currently used NX-19 correlation for natural gas custody transfers and provide more accurate values for the supercompressibility factor, compressibility factor, and other derived thermodynamic properties. The equation of state for the pure fluid is currently based on corresponding states methods while the composition dependence utilizes the combined advantages of rigorous second virial mixing and conformal solution mixing. The equation of state predicts methane compressibility factors within 0.03 percent of selected experimental data in the major custody transfer region. In this region, the compressibility factor predictions for other major natural gas components are usually within 0.2 percent and in many cases within 0.1 percent of selected experimental data. Compressibility factor comparisons with selected experimental binary mixture data for eight mixtures indicate an agreement within 0.05 percent on the average. When the correlation is used to predict compressibility factors of 21 actual gas mixtures the overall uncertainty is less than 0.05 percent.
