摘要
介绍了用Excel计算和图表功能,是对二元非理想体系进行逐板计算法和图解法相结合求精馏塔理论塔板数的一种新方法。对方法中的关键问题如曲线拟合和单变量求解等进行了具体分析和说明。计算方法简单实用,无须编程。经实例验证结果准确,具有实用性和一般性。
A new method for calculating the theoretical number of distillation columns in a binary non-ideal system by combining the plate-by-plate method and the graphic method with the Excel calculation and chart functions was introduced. The key problems in the method, such as curve fitting and univariate solving, were specifically analyzed and explained. The calculation method is simple and practical. The results of the examples have verified the accuracy, practicality and generality of the method.
