本研究係探討由丙二醇甲醚與醋酸進行酯化反應產生丙二醇甲醚醋酸酯之製程設計與控制，丙二醇甲醚醋酸酯是一種工業界及電子業界重要的溶劑，因具有較低的蒸氣壓以及可抑制抗蝕劑微粒的形成，在電子產業中用於調配光阻劑。丙二醇甲醚醋酸酯同時也是在樹脂原料、墨水用溶劑、及紡織工業中一種重要的反應物。研究中首先選擇合適的熱力學及動力學模式來描述程序，並使用Aspen Plus進行穩態模擬。本研究系統為可逆反應，並尋求最小年度總成本(TAC)為目標，來提出系統之最適化流程，分別討論反應蒸餾塔及共沸蒸餾塔兩系統之設計概念與最適化結果，進而提出整廠系統，並將未反應之反應物回收利用，改動進料位置來找到最小年度總成本(TAC)之設計。
本研究接著將探討整廠製程之控制策略，利用Aspen Dynamic進行動態模擬及控制。控制策略方面，使用基本的控制環路，並且利用敏感度分析來尋求每一個操作單元最適合的控制點，接著給予進料量增減的干擾及進料組成改變的干擾，找到一個控制策略能使整個系統在干擾下快速回穩，並保持產物的純度。

In this research, design and control of a reactive distillation column to produce propylene glycol mono-methyl ether acetate (PGMEA) from propylene glycol methyl ether (PGME) and acetic acid (AA) via the esterification reaction is proposed. PGMEA is widely used as the photoresist in electronics industry and it is also important reactant in other industry. First of all, suitable thermodynamic and kinetic model are chosen to describe this process and perform the steady-state simulation by Aspen Plus. The system in this process is a reversible reaction and seeking out the optimum goal is obtained by minimizing the Total Annual Cost (TAC). After two optimum designs which are about reactive distillation column and azeotropic distillation column are obtained, we connect each unit into a plant-wide process and recycle the un-reacted reactants. Then, we change the feed location to look for the optimum process.
After that, we will discuss the dynamic simulation and control of the plant-wide process by Aspen Dynamic. A simple control strategy has been brought forward, and the sensitivity analysis is performed to find the suitable control of each unit. With the interference by adjusting the feed flow rate and feed composition, the proposed control strategy works effectively and holds the purity of the product.
