摘要：

Experimental data on fluid phase equilibria in binary mixtures of water with typical natural gas and oil components (light and heavy alkanes, nitrogen, hydrogen sulfide, carbon dioxide) have been examined and the phase behavior of these mixtures over wide ranges of temperature and pressure is reviewed. A quasi-chemical group-contribution hole model is used for calculating the phase equilibria in these systems. With few exceptions the model predicts correctly the basic types of phase behavior and, expect for gas-gas equilibria, the accuracy for all the binaries and two multicomponent aqueous mixtures tested is satisfactory.
