本研究目的係探討丙烯酸乙酯製程之設計與控制。首先選擇合適的熱力學與動力學模式來描述程序,並使用Aspen Plus®進行穩態模擬。本研究提出偶合塔與反應蒸餾塔系統性最適化流程,以年度最大利潤為目標,得到兩種設計流程下各別的最適化之穩態設計操作條件,以偶合塔設計流程之年度最大利潤較反應蒸餾塔設計流程大。接著用Aspen DynamicsTM進行動態模擬。從干擾排除測試來看,以反應蒸餾塔的設計流程下以乙醇/丙烯酸進料比率控制反應蒸餾塔第五板板溫,同時以汽提塔再沸器加熱量來控制汽提塔第五板溫度的控制策略之結果較佳。
The aim of this research is to study the design and control of Ethyl-Acrylate process. First, we use the suitable thermodynamic and kinetic model parameters to describe the process, and then use the Aspen Plus® to do steady state simulation. The design procedure is proposed to obtain the optimum flowsheets of coupled reactor/column and reactive distillation column. The annual maximum profit is used to obtain the optimum process design and operating condition of those two processes. After that, we use the Aspen DynamicsTM to do dynamic simulations. In the process of reactive distillation column, simulation results demonstrate that the effective dynamic control is provided by a control strategy that uses Ethanol/Acrylic-Acid feed ratio to control 5th stage temperature of first column and uses the second column reboiler duty to control 5th stage temperature of the same column. This control strategy is able to maintain the impurities of product stream in the face of various disturbances.
