Assessment of the Pressure-Volume-Temperature-Composition (PVTx) Data of the CO2-H2O System

摘要：

　　Eight sets of experimental data of pressure-volume-temperature-composition (PVTx) properties of the CO2-H2O system within 0-80 MPa and 278.15-293.15 K were carefully assessed, where three data sets involve two or three coexistent phases.The results show that one set has bigger systematic errors, and two sets have large systematic errors and uncertainties.Three groups of data (Yajinuma et al., 2000; Song et al., 2010; Yan et al., 2011) have high precisions, but two of them may have small systematic deviations.Another two sets of data overally have good precisions, but a few data have large deviations (Kojima et al., 2001; Capobianco et al., 2013).
