calculated using the Modified Peng Robinson (MPR) equation of state. The solid phase fugacities of pure components are evaluated indirectly from equation of state by the fugacity ratio. Fraction properties are estimated by use of PNA analysis and for evaluating enthalpy of fusion a correlation is developed. The major aim for performing this research was to develop a thermodynamic – computerized model for predicting WAT and the amount of precipitated wax in petroleum mixtures. The model has been applied to calculate wax appearance temperature and the amount of
precipitated wax for some North Sea and synthetic oils. The predicted results are in very good agreement with experimental data.
