Molecular parameters for linear perfluoroalkanes: (a) segment diameter; (b) dispersive energy. Lines correspond to the values from the relationships of Equations III.31-III.33. Table III.2 compares for the same temperature range the absolute average deviation (AAD) obtained when soft-SAFT and the Peng-Robinson equations of state are used to correlate experimental density and vapour pressure data for highly fluorinated compounds and also for the gases under study. Generally it can be said that soft-SAFT correlates experimental vapor pressure and density data better than the Peng-Robinson EoS for all the compounds studied (gases and liquids) except for the lower molecular weight perfluoroalkanes where soft-SAFT gives higher deviations in vapor pressure. - 113 - (a) (b)
