对反应精馏过程的多定态能控性进行了分析。我们将RD柱用于甲基叔戊基醚（驯服）合成的案例研究。该模型由五个PI控制器组成，分别控制液位、进料流量、塔顶压力和塔底产物组成。在MSS上选取上、中、下三种情况下的动态模拟初始条件。控制产品组成，使进料流速和回流比扰动± 10%。然而，压力扰动未能保持设定点。这些现象能够解释分岔图。
In this paper, the controllability of reactive distillation (RD) on the multiple steady states (MSS) was analysed. We used the RD column for tert-amyl methyl ether (TAME) synthesis for a case study. The model was prepared five PI controllers which control liquid level, feed flow rate, pressure of column overhead and bottom product composition. Initial conditions of dynamic simulation were chose three cases each of upper, middle and lower branches on the MSS. Product composition was controlled for the ±10 % disturbances of feed flow rate and reflux ratio. However, pressure disturbance was failed to keep the set point. These phenomena are able to explain the bifurcation diagrams.
