Summary

Liquid densities predicted by the Peng-Robinson equation have been improved by incorporating a Gaussian-like volume translation which is a strong function of temperature near the critical point but becomes a constant value away from the critical point, without any discontinuities in the critical region. This simple method provides liquid densities for 283 nonpolar, polar and hydrogen-bonding fluids with an overall average absolute deviation of 0.70%, which compares favorably with existing volume translation and dedicated liquid density calculation methods.
