乙二醇与乙酸酯化反应的双反应段反应精馏塔设计
A reactive distillation system with double reactive sections for the esterification of ethylene glycol with acetic acid
将一种具有新型反应精馏结构的双反应段反应精馏塔应用于乙二醇与乙酸连续两步酯化反应，详细分析了精馏塔的稳态性能并探讨其节能效果。以最小化总的年度费用(TAC)为目标，优化双反应段反应精馏塔结构，并将此优化结构与单反应段反应精馏塔优化结构进行比较。结果表明在双反应段反应精馏塔中，设计变量的增加能够有效协调两步反应之间的关系，提高反应效率和分离效果，使双反应段反应精馏塔TAC减少了23.58%，实现节能效果。
