Word环境Matlab馏出液组成恒定的间歇精馏工艺计算研究

以正庚烷-正辛烷溶液为例,研究了Word与Matlab Notebook动态链接和交互作用,计算保持馏出液组成恒定的间歇精馏工艺,得到两个重要结论:(1)釜液组成随回流比变化为Xw=-0.0012R3 0.0276R2-0.2217R 0.7581,呈3次函数关系。因此,操作结束的釜液组成不应低于0.14;(2)数值计算dx取值大小,对精馏时间的影响为T=7.0729dx2 0.045dx 2.5648。故该方程的极限值即为不受计算过程影响的准确精馏时间。

Study of process calculation of running a batch distillation to fixing overhead components combining of Matlab with Word

It is shown to calculate quantitatively running a batch distillation to fix overhead component by means of chaining Microsoft Word with Matlab Notebook as an example of n-heptane and n-octane, and gets the facts that relationship between components of liquid within the still and reflux ratio of ft is X, = -0. 0012ft3 0. 0276ft2 -0. 2217ft 0. 7581 , witch is third-order power function, then in speaking economically the component at ending operation is not less than 0. 14, and that magnitude of dx effecting on operating time calculated is T = 7. 0729dx2 0. 045dx 2. 5648 , in light of, accurate operation time is limit value of the equation.
