Thermodynamic Properties of Homogeneous Mixtures of Nitrogen and Water from 440to 1000 K, Up to 100 MPa and 0.8 Mole Fraction N2

摘要

A generalized corresponding-states model of the Helmholtz free energy for fluidmixtures, with pure water as the reference fluid, has been used to model the solubility and thermodynamic properties of nitrogen in water in homogeneous states in a wide range of temperatures and pressures around the water critical point. The model predictions are compared with the literature data available in this range. Tabulated values of density, enthalpy, isobaric heat capacity and fugacity coefficients are presented at selected entries of pressure from 0.05 to 100 MPa, of temperature from 440 to 1000 K, and of nitrogen mole fractions up to 0.8. Also presented are tables of infinite-dilution (standard-state) properties of the nitrogen solute in the same pressure and temperature range.
