Estimation of PC-SAFT equation of state parameters of hydrocarbons, alcohols and ethers

New fitted parameters of PC-SAFT (EoS) of hydrocarbons, alcohols and ethers, are reported. Results obtained from alkanes, alkanols and ethers show that the new fitted PCSAFT parameters are much better comparing with those exist in the literature. Moreover, for alkanes, the percent AAD values of liquid density and vapor pressure are under 2.2%, for alkanols, the AAD is 1.95% for liquid composition and 0.07% for vapor composition, then for ethers, the AAD is 0.85% for liquid composition and 0.19% for vapor composition.
