本研究應用Underwood簡捷法估算反應蒸餾塔(Reactive Distillation, RD)及反應性分隔內壁蒸餾塔(Reactive Dividing Wall Column, RDWC)所需之最小蒸氣量。於反應蒸餾程序中,化學反應通常會伴隨反應熱產生,因此不同系統必須有相對應的修正並做出額外的假設,使Underwood簡捷法可以成功地應用於吸熱及放熱系統。
於理論推導程序中,分別以兩種計算方式進行RD及RDWC程序之探討,並且藉由商業模擬軟體Aspen Plus建立不同條件下之理想反應蒸餾程序、反應性分隔內壁蒸餾塔以及碳酸二苯酯(Diphenyl carbonate, DPC)反應蒸餾製程及其熱耦合組態。
根據比較結果顯示,I_P (HK+LK⇌HHK+LLK)為RD程序估算最精準之組態,誤差值介於- 8.02%至11.04%,並且於RDWC程序中,此組態之估算誤差值介於- 10.64%至16.16%亦為最準確之組態。對於真實系統而言,DPC反應蒸餾製程之塔底總蒸氣量誤差為+1.46%,熱耦合設計之誤差則為+19.69%,故驗證此簡捷法可以有效地作為初步設計的起始猜測值。
The objective of this study is to extend Underwood’s concept to reactive distillation (RD) column and reactive dividing wall column (RDWC), but the exothermic and endothermic reactions in the distillation column will cause the difficulty in derivative procedure. Thus, the modified terms and the additional assumptions are necessary in order to simplify the derivation procedure.
In the derivation procedure, there are two different concepts applied in RD and RDWC processes, furthermore, the ideal cases and the realistic cases are used to compare the difference between the shortcut method and rigorous simulation. Also, RD processes, RDWC processes, diphenyl carbonate (DPC) RD and RDWC process are simulated by commercial software Aspen Plus.
According to the results, I_P (HK+LK⇌HHK+LLK) configuration has the lowest deviation error in RD and RDWC process (RD: - 8.02% ~ 11.04%, RDWC: - 10.64 ~ 16.16%). For the DPC process, the percent deviation for RD is +1.46% and +19.69% for RDWC, it shows that the novel shortcut method is effective and helpful.
