In this work, we have calculated the Joule-Thomson inversion curve of two important associating fluids, namely water and methanol, from the SAFT equation of state. Comparisons with the available experimental data, for water and methanol indicate that this molecular based equation of state gives good prediction of the low temperature branch; but, unfortunately, due to lack of isenthalpic data for high-pressure-high- temperature gas condensate for water and methanol, the reliability of model predictions could not be completely verified. We have also reported the influence of the molecular dipole moment and the segment number on the Joule-Thomson inversion curve.
