This study presents a new empirical model for quick calculating compressibility factor of natural
gas. The model derived from 2918 experimental data of natural gascompressibility factors
presented in this study. The new empirical correlation can acculately predict natural gas
compressibility factors at variety ranges of pseudo reduced pressure from 0.01 to 15 and pseudo
reduced temperatures from 1 to 3. The accuracy of model is compared to commonly used
empirical methods used in this work. Results showed that the new proposed correlation has 0.847
of AARD% relative to experimental data. The comparison indicates the superiority of the new
method over the other methods used to calculate natural gas compressibility factors.
