DENSITY OF SODIUM CHLORIDE SOLUTIONS AT HIGH TEMPERATURES AND PRESSURES

Abstract

A correlation equation is given which reproduces the density of sodium chloride solutions to +- 4% over the ranges 0 to 5 molal, 0 to 350/sup 0/C and 1 to 1000 bars. Data generated from the equation are compared with selected experimental and smoothed values at typical temperatures, pressures and concentrations. Data are included for the density of sea water concentrates up to 150/sup 0/C and 150 g/kg salinity at saturation vapor pressures based on a fit to a Chebyshev polynomial.
