Abstract

This paper describes a method for very accurate correlation of the thermodynamic properties of LNG and LPG mixtures. The method, which is based on the principle of corresponding states, is capable of correlating LNG densities to within 0.1% and LPG densities to within 0.2%. Dew and bubble points, mixed- or single-phase enthalpies, and phase splits are calculated with errors generally not exceeding the experimental ones. A comparison has been carried out covering all available experimental data for the species in question, i.e., C 1 through C 5, nitrogen, carbon monoxide, carbon dioxide, and hydrogen sulfide. A summary of results demonstrates the capability of the present correlation to cover both the normal and the critical regions with high accuracy.
