| Abstract: | For the purpose of precisely correlating the data of vapor-liquid equilibria, the present paper proposes a new model named Pseudo-Component Model. Thirty eight sets of isothermal binary systems were chosen to test the model. The findings are as follows:
1. Under a moderate pressure, isothermal vapor-liquid equilibria of binary systems can be correlated by Pseudo-Component Model, with its correlation precision much better than that of UNIQUAC.
2. Pseudo-Component Model car, be applied to various non-ideal systems, especially it can describe the compositions and pressures of azeotropes rather precisely. |
