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。 Taking n-heptane-n-octane solution as an example, the dynamic link and interaction of Word and Matlab Notebook were studied, and the batch distillation process with constant composition of distillate was studied. Two important conclusions were obtained: (1) The reflux ratio changes to Xw = -0.0012R3 + 0.0276R2-0.2217R + 0.7581, which is a cubic function. Therefore, the end of the operation of the composition of the kettle liquid should not be less than 0.14; (2) Numerical calculation dx value size, the distillation time of T = 7.0729dx2 +0.045dx +2.5648. Therefore, the limit of this equation is the accurate distillation time which is not affected by the calculation process.
