A new synthesis method for reactive distillation processes is proposed. At each stage of a column, vapor–liquid equilibrium (VLE) is assumed and kinetically controlled reaction in liquid phase is considered. First, the liquid composition space is divided into small subspaces. Then, for each subspace a representative liquid composition is decided and assigned to a module corresponding to a stage of a distillation column. Then, after the calculation of the VLE and the reaction rate, the distribution network (superstructure) connecting all modules by vapor and liquid flow paths is constructed. The feature of the proposed model is that all constraints are linear to the optimization variables: the liquid and vapor flow rate and the liquid hold-up. The developed method was applied to the metathesis reaction of 2-pentene, and a completely new process structure was obtained. The effectiveness of the implied structure was confirmed through a comparison with conventional structures.

使用 IDEAS 方法进行反应精馏过程的高效结构合成

提出了一种用于反应精馏过程的新合成方法。在塔的每个阶段，假定气液平衡 (VLE) 并考虑液相中的动力学控制反应。首先，液体成分空间被划分为小的子空间。然后，对于每个子空间，确定代表性液体成分并将其分配给对应于蒸馏塔级的模块。然后，在计算 VLE 和反应速率后，构建通过蒸汽和液体流动路径连接所有模块的分配网络（上部结构）。所提出模型的特点是所有约束都与优化变量呈线性关系：液体和蒸汽流速以及液体滞留量。将该方法应用于2-戊烯的复分解反应，并获得了全新的工艺结构。通过与传统结构的比较，证实了隐含结构的有效性。
