Calculation of phase equilibria in nitrogen-ethane mixtures by extended corresponding states

Zusammenfassung: | The phase diagram for the nitrogen-ethane mixture is determined via the extended corresponding states one-fluid theory. We support the contention that this mixture is a Type III mixture with a three-phase (liquid-liquid-vapour) line. This line can be calculated extremely well if binary interaction factors are fitted to the three-phase data. Without further adjustment, the liquid-liquid equilibrium (LLE) and vapour-liquid equilibrium (VLE) for the system are predicted satisfactorily. The parameters used, however, are not sufficient to predict satisfactory VLE data near a mixture critical line. This conclusion is in agreement with our previous work. |
