heal.abstract New correlations are presented for the critical properties and the acentric factor as functions of the parameters (data) typically available for heavy undefined fractions: the Molecular Weight (MW) and the Specific Gravity (SO) at 60/60°F. The validation of the proposed method, in comparison with those of Kesler-Lee and Twu, is performed on: a. Vapor pressures (Ps) and saturated liquid densities (d1s) of petroleum and coal liquid fractions. b. Solubilities and liquid densities for binary systems of CO2 with petroleum and coal liquid fractions and with bitumens. c. Constant Volume Depletion (CVD) for gas condensates. d. Differential Liberation (DLE) for crude oils. The proposed correlations perform generally better than the other two, especially for high MW fractions, resulting in satisfactory predictions of the VLB and PVT behavior even for reservoir fluids with only one adjustable parameter at the saturation point. en
