由於近年來生質柴油大量生產，使得發展其副產物甘油的再利用製程越來越受到重視，而本研究係探討其中一種甘油應用為將甘油與醋酸酯化反應產生三醋酸甘油酯(Triacetin)。此產物能應用在塑化劑、高分子塗膠劑、炸藥、菸草、藥物及化妝品之添加劑。
整廠之設計首先選定合適的熱力學與動力學模式來描述程序之相平衡及反應，研究中採用Hasabnis and Mahajani (2010)所回歸之LHHW反應速率模式及動力參數，並使用Aspen Plus V7.1進行穩態模擬。本研究利用多階段反應進行酯化反應製程，並延用上述論文所提出之反應蒸餾整廠架構進行討論及改良，最後以最小總年度成本(TAC)為目標提出系統最適化流程。

Due to the tremendous development for the production of biodiesel , the process of utilizating glycerol ( as by-product in biodiesel process) has gained a lot of attention in recent years. One of the various possibilities that this work explores is on glycerol esterification with acetic acid to produce triacetin. Triacetin is used mainly as a plasticizer and a gelatinizing agent in polymers and explosives and as an additive in tobacco, pharmaceutical compounds,and cosmetics.。

This work chooses the suitable models to describe the thermodynamics and kinetics for the process design, and then simulates the process by using Aspen Plus V7.1. The series of reactors are used for the reaction system, and the overall process design be adopt and improved the concept by Hasabnis and Mahajani (2010). Design objective is to minimize the total annual cost (TAC) by varying dominant design variables.
