Thermodynamic Properties of Glycols Using PC-SAFT

Perturbed-chain statistical associating fluid theory (PC-SAFT) is used to obtain pure compound parameters of monoethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and 1,2 propylene glycol. These parameters are used to calculate the vapor pressures and saturated liquid densities of glycols. The heat of vaporization and liquid heat capacities for the glycols are also predicted satisfactorily. However, PC-SAFT is not predictive for all the caloric properties of monoethylene glycol, triethylene glycol and 1,2 propylene glycol.
