采用基于模拟的设计方法来找出用于生产乙酸丁酯的有前景的反应精馏工艺配置。利用 Amberlyst-15 催化剂1上的酯化反应和不需要的副反应醚化反应的本征动力学来评估不同反应蒸馏过程的稳态性能。开发了稳态塔模型，并与文献中的实验数据进行比较。2,3 利用该模型，研究了三种不同的塔配置用于乙酸丁酯的生产，目的是消除副产物二丁醚的形成并获得高纯度的所需产物乙酸丁酯。探索了以下塔配置：(a)具有非反应性精馏段和反应性汽提段的塔； (b)具有非反应性精馏段、非反应性汽提段和反应性中间段的塔； (c) 常规蒸馏...
A simulation-based design method is employed to figure out the promising reactive distillation process configuration for the production of butyl acetate. The intrinsic kinetics developed for the esterification and the unwanted side reaction etherification over the Amberlyst-15 catalyst1 are utilized to evaluate the steady-state performance of different reactive distillation processes. A steady-state column model is developed and compared with experimental data from the literature.2,3 With this model, three different column configurations are investigated for the production of butyl acetate with the goal of eliminating the formation of byproduct dibutyl ether and achieving a high purity of the desired product butyl acetate. The following column configurations are explored: (a) a column with a nonreactive rectifying section and a reactive stripping section; (b) a column with a nonreactive rectifying section, a nonreactive stripping section, and a reactive middle section; and (c) a conventional distillation...
