• In the present work, available direct and indirect methods for isobaric liquid heat capacity estimation are evaluated relative to experimental data. The study focuses on identification of systemic and random deviations between specific calculation approaches and experimental data, based on characterization method so that their preferred range of use in process simulators can be identified. The roles for new elemental composition based predictive heat capacity correlations in particular are explored. In order to implement these element-based heat capacity correlations into commercial chemical engineering process simulator software, the number of atoms per unit mass, must either be available from experimental measurement, or be estimated from available property data with little deviation because both heat capacity correlations are sensitive to this value.
