摘要
在自建的汽液平衡装置上，测定了压力为 ４．００～１０１．３２ｋ Ｐａ 条件下近 １５０ 个窄馏分汽液平衡常数 Ｋ 值；回归了 ４ 个 Ｋ 值计算式，回归式 Ｋ 值最大平均绝对偏差为７．０％ ，泡点温度的最大绝对平均偏差为 ６．０ ° Ｃ。
At low pressures (4.00～101.32kPa), about 150 vapour liquid equilibrium (VLE) constants of petroleum fractions of three Chinese main crude oils (Zhongyuan, Gudao and Kelamayi oils) were determined by fluid VLE experiment. 4VLE constants correlation equations are suggested for narrow petroleum fractions of the three crude oils. These equations have a mean percentage deviation 7.0% for K and a mean absolute deviation of 6.0 °C for equilibrium temperature (bubble point).
