摘要：

The fluid phase behaviour of the ternary system methane + ethane + eicosane was studied experimentally with special emphasis on liquid-liquid-vapour equilibria and retrograde condensation of the second, heavier liquid phase in this region. P, T sections for mixtures of constant composition were determined according to the synthetic method for nine constant molar ratios of ethane and eicosane and different mole fractions of methane. The temperature range investigated was 290-307 K and the pressure range 5.0-6.4 MPa. Addition of methane to a binary ethane + eicosane mixture expands the three-phase curve to a region and shifts it to lower temperatures. The influence of the concentration of eicosane and of methane on the phase behaviour in the three-phase region and on retrograde phenomena is discussed.
