摘要
本文采用克劳修斯—克拉珀珑衍生方程和已有的数据导出了LPG各组分的饱和蒸气压与温度的关系式,绘制了示例组分LPG饱和蒸气压随温度的变化曲线,从该曲线可以直接读取饱和蒸气压大小,并可以直观看出饱和蒸气压随着温度的升高呈几何倍数的增加。
In this paper,the relational expression of saturated vapor pressure and temperature of LPG is deduced according to the derivative one of Clausius-Clapeyron equation and some ever data.The figure of the above expression about LPG with some kinds of components is drawn.We can read the saturated vapor pressure value directly from the figure.We can also see the obvious trend of the accelerated rise in saturated vapor pressure with the increasing temperature.
