采用动态模拟的方法研究了启动策略对乙基叔丁基醚反应精馏的影响。由于每次反应精馏都可能出现输入多态，因此研究了输入多态对启动的影响。以ETBE反应精馏为例，展示了ETBE塔启动过程中的特征行为。研究发现，给定的启动策略会影响启动条件的动力学特性。在进行启动操作之前，了解输入多重性是必要的要求，以避免过多的能量，以实现稳定的最佳工艺运行。
Dynamic simulation is used to understand the effect of a startup policy on the ethyl tert-butyl ether (ETBE) reactive distillation. Because input multiplicity is likely to occur in every reactive distillation, its effects on startup are investigated. The ETBE reactive distillation is presented as an example to show characteristic behaviors during startup of the ETBE column. It is found that the dynamics of the startup condition are influenced by the given startup policy. An understanding of the input multiplicity is a necessary requirement before performing the startup operation to avoid excessive energy, to achieve a stable optimum process operation.
