摘要
在回收废有机玻璃再生生产甲基丙烯酸甲酯的工艺路线中,甲基丙烯酸甲酯的粗产品需要进行精制分离以达到更高的质量分数。对这一技术工艺进行研究,设计了隔壁塔的工艺流程,同时设计了一个双塔流程作为基础和对比。利用总年度费用作为目标函数对精馏过程进行了全局经济优化,得到了最佳的工艺参数。结果显示,隔壁塔流程可以节约43.5%的能量和22.3%总年度费用,具有更好的经济优势。
In an industrial process to produce methyl methacrylate（MMA） with recycling acrylic plastics,the crude MMA product needs to be separated to get a higher purity. In this work,a dividing wall column（DWC） process is developed and a two-tower flow is designed as the foundation and control. Using total annual cost（TAC） as the objective function,the optimal design of the conventional two-column process and the DWC process is investigated. It is revealed that proposed DWC process can save 43. 5% of energy. Significant reduction on the total annual cost（22. 3%） can also be realized with the additional benefit of having only one column shell.
