Developing a Thermodynamic Model to Prediction of Cloud Point Temperature in Waxy Hydrocarbon Fluids

In this paper, a thermodynamic model for prediction of cloud point temperature in hydrocarbon waxy fluids is presented. In this study the solid model is used and the activity coefficients are calculated using modified regular solution theory. To calculate these coefficients, some other parameters such as the melting enthalpy, heat capacity difference should be calculated. In order to improve the outputs of the model, some tuning parameters are entered in the model and then these parameters are tuned using experimental data in liturature. The results of the present model were compared with experimental data collected from literature and the other models. Comparisons showed a good match between the results and the maen error of less than 0.5% was calculated.
