“…The approach used to estimate the uncertainty in isothermal compressibility of seawater, given in Appendix A, could not be used for isobaric expansivity as expansivity was not found to vary linearly with salinity. This non-linearity was verified by analyzing data on the isobaric expansivity of aqueous sodium chloride reported by Rogers and Pitzer [45] for a wide range of temperature, salinities, and pressures (0 ≤ t ≤ 300 °C; 0 ≤ S ≤ 226 g/kg; 0.1 ≤ P ≤ 100 MPa) and, by analyzing seawater data reported by Safarov et al [5]. The only alternative we saw to obtain an upper bound on the uncertainty in this range (S > 56 g/kg) was by comparing values obtained from the correlation for isobaric expansivity of seawater developed in this work, given in Eq.…”

Thermophysical properties of seawater: A review and new correlations that include pressure dependence

In a previous paper, the authors have given correlations for seawater thermophysical properties as functions of temperature and salinity, but only for near atmospheric pressures. Seawater reverse osmosis (SWRO) systems operate routinely at pressures of 6 MPa or more; however, experimental data for seawater properties at elevated pressures (P = 0.1-12 MPa) are limited to a salinity of 56 g/kg. To accurately model and design SWRO and thermal desalination systems, a reliable method of estimating the effect of pressure on seawater properties is required. In this work, we present this method and new correlations for seawater thermophysical properties that are valid within the range: t = 0-120 °C, S = 0-120 g/kg, and P = 0-12 MPa. Seawater isothermal compressibility data, available until a salinity of 56 g/kg, were used to develop a correlation for compressibility that is extrapolated to 160 g/kg. Thermodynamic identities were then used to develop accurate pressure dependent correlations for seawater: density, isobaric expansivity, specific heat capacity, enthalpy, entropy and Gibbs energy. New correlations were proposed for 2 surface tension and osmotic coefficient were reviewed. Uncertainty bounds were calculated for each correlation.
