探索了一种新的测定流体混合物露点密度和露点压力的方法，并与传统方法进行了比较。用双沉头磁悬浮密度计研究了三种甲烷+丙烷混合物在(248.15~293.15)K温度范围内的(p，ρ，T，x)行为，测量范围从低压扩展到两相区。重量法制备的混合物的组成为(0.74977、0.50688和0.26579)摩尔分数甲烷。我们通过以下方法分析等温数据：(1)单相区(p与ρ)数据的维里拟合与两相区数据的线性拟合的交集的“传统”分析；(2)沉降片表面吸附质量的分析。我们将这些实验与传统的等容实验进行了比较。我们的结论是，等温实验的“吸附质量”分析提供了露点温度、压力和密度的准确确定。但是，需要一个双沉降器密度计。
We explore a novel method for determining the dew-point density and dew-point pressure of fluid mixtures and compare it to traditional methods. The (p, ρ, T, x) behavior of three (methane + propane) mixtures was investigated with a two-sinker magnetic suspension densimeter over the temperature range of (248.15 to 293.15) K; the measurements extended from low pressures into the two-phase region. The compositions of the gravimetrically prepared mixtures were (0.74977, 0.50688, and 0.26579) mole fraction methane. We analyzed isothermal data by: (1) a “traditional” analysis of the intersection of a virial fit of the (p vs. ρ) data in the single-phase region with a linear fit of the data in the two-phase region; and (2) an analysis of the adsorbed mass on the sinker surfaces. We compared these to a traditional isochoric experiment. We conclude that the “adsorbed mass” analysis of an isothermal experiment provides an accurate determination of the dew-point temperature, pressure, and density. However, a two-sinker densimeter is required.
