摘要：

Calculation of phase equilibrium for a mixture of given composition requires specification of two process variables, typically chosen from among the following: temperature, pressure, vapour fraction, enthalpy, entropy or volume. The difficulties associated with solving the equilibrium equations are strongly related to the chosen selection of these process variables. The aim of the present paper is to outline the characteristics associated with the different types of specification in order to provide guidlines for efficient and robust solution algorithms.
