The measured data have been fitted by means of varied mathematical models and the optimum parameters of the Antoine equation have been determined. 并用不同数学模型进行了数据的拟合,求出最佳方程相应的参数,获得了满意的结果。
The Virial equation was used to calculate the fugacity coefficients of vapor phase, and Antoine equation was used for the saturated vapor pressure of benzene and toluene. 用维利方程计算汽相的逸度系数,用Antoine方程计算饱和蒸汽压,用NRTL方程计算液相的活度系数。
Determination of Antoine Equation Constants for LPG LPG的Antoine方程常数的确定
For petroleum fractions, VLE system at low pressure and the modified reduced Antoine equation are recommended for the calculation of phase equilibrium. 推荐使用修正的对比态Antoine方程进行低压体系馏分油的汽液平衡计算。
It was found that the multi-parameter model describing the relation of vapor enthalpy and temperature ( Clapeyron-Clausius equation) is obviously superior to the commonly used two parameters model and the Antoine equation in term of residual square sum and statistic distribution rule of error. 从拟合的残差平方和和误差的统计分布规律考虑,基于蒸发焓与温度关系(Clapeyron-Clausius方程)的多参数模型明显优于常用的二参数模型和Antoine方程。
The prediction of the constants in some other vapor pressure equations including widely used Antoine equation and a method to calculation the fugacity of saturated liquids are also discussed. 本文也讨论了包括广泛使用的Antoine方程在内的其他蒸汽压方程中参数的预测以及关于饱和液体逸度的一种计算方法。
