本文比较了多种现有的烃类饱和蒸气压推算方法,结果表明对 C-{10}以上的烃在常沸点以下以 Lee-Kesler 的经验式(B)为最佳。本文还提出为了进行这类计算所需初始值的经验式和误差方法,以便程序化求解。
In this paper, we compare a number of existing methods for estimating the saturated vapor pressures of hydrocarbons. The results show that the hydrocarbons above C - {10 } are best under Lee-Kesler’s empirical formula (B) below the normal boiling point . The paper also presents empirical and error methods for the initial values needed for such calculations in order to programmatically solve them.
