Rigorous dynamic models for distillation safety analysis.pdf

照着鲁本先生的Rigorous  dynamic  models  for   distillation  safety   analysis这篇文献做的，在稳态中，外挂的再沸器不能直接回流通回塔中（不收敛），鲁本先生说在dynamics中就可以收敛了，可是导入dynamics后，双击精馏塔，不会出现ASPEN Plus中的那个界面了，也就没法选择再沸器回流是导入哪个塔板了啊？怎么处理呢？

比较新的Luyben大师的文献了！
在此附上文献，共大家学习及交流！

Dynamic simulations of distillation columns are widely used to develop effective control structures. The
normal distillation models assume instantaneous heat transfer in the condenser and reboiler. However,
when dynamic simulations are used in the analysis of safety problems in the event of emergency situations,
the basic model does not accurately represent the dynamic response. Accurate response times
are essential in the design of safety systems for the column. For example, a failure of the supply of cooling
water will lead to rapid increases in pressures and temperatures that occur in seconds. Accurately
determining the rates of increase in these important variables and the time period to reach critical limits
(safety response time) permits the engineer to quantitatively design effective safety systems.
This paper illustrates how rigorous condenser and reboiler models can be developed in Aspen Plus and
their dynamics evaluated in Aspen Dynamics.

看过了啊……就会没搞清楚他在dynamics里是怎么把之前的分裂流股给合到一起的啊

按照luyben大师以前用dynamic收敛稳态是这样：断裂位置，在稳态使两个流股参数基本保持一致（组成，温度，压力），这样进入dynamic，删除其一，直接闭合。

鲁本大师的东西，一定是好东西，嘿嘿
