Volumetric properties of normal fluids at low temperatures: An extension of Pitzer's generalized correlation

摘要: The three-parameter tabular correlation of Pitzer et al. for calculating the compressibility factor pure components has been extended to lower temperatures in region where Tr is from 0.5 0.80 and Pr 0 9. compressibility-factor expressed linearly acentric Z = Z(0) + ωZ(1) with values Z(1) tabulated terms Pr. generalized tested 21 compounds a total number 463 data points. average deviations calculated factors are 1.63% compressed liquids 0.67% gases.
