Natural gas (NG) is a mixture of 21 elements and widely used in industries and domestics.
Knowledge of its thermodynamics properties is essential for designing appropriate process and
equipments. In this study, the detailed numerical procedures for computing sound speed of natural
gas mixtures have been discussed based on AGA8 equation of state (EOS) and thermodynamics
relationships. To validate the procedures, the numerical values have been compared with available
measured values. The validations show that the average absolute percent deviation (AAPD) for
speed of sound calculations is 0.133%. AAPD values indicate that the numerical procedure could
predict sound speed of natural gas with very high accuracy. The results also show that sound speed
calculation based on AGA8 is more accurate than the cubic EOSs
