The model combing the method UNIFAC with various model methods was applied for calculation of activity coefficients in an VLE model for hexaflourobenzene(1) benzene(2) at 333.15K, butanol(1) tetrachloroethene(2) at 101.08 kPa, carbondioxide(1) 3-pentanol(2) at 313.2K and other system compounds. The simulated results represent the overall average relative deviation below 0.5% which is comparable to the results presented by other authors in the literature. The data and results obtained for the systems are compared with the compositions predicted by the model and the sensitivity of the model parameters towards the composition data was analyzed through simulation techniques. The results predicted that overall error convergence was found to be less than 0.5 %.
