雙成份常壓蒸餾塔之視窗程式設計

Windows Programming of Binary Distillation Column under Atmospheric Pressure

指導教授 : 林顯聖

摘要


蒸餾塔是化學工業中常用且重要的程序之一,藉由物質沸點的不同,達到分離與純化的效果。本研究期望開發出一座雙成份常壓蒸餾塔,使用者輸入欲分離之成份參數、蒸餾塔總板數、進料板位置、塔頂回流量、塔底加熱量等,便可進行穩態模擬,再藉由穩態模擬結果進行動態模擬,以提供學習使用 本研究利用Microsoft Visual Basic 2010程式語言作為視窗程式之開發工具,程式之撰寫是以質量平衡、能量平衡、相平衡作為基礎,並建立各個單元之副程式模組,再加入塔頂與塔底控制器來達到控制產品品質的目的,整合成一完整的視窗模擬程式。 由模擬結果可知,其穩態數據與文獻相近且動態應答合理。因此本模擬程式可幫助了解雙成份蒸餾塔之特性以及控制策略之研究。

The distillation column is a common and important operation unit in the chemical industry. The process utilizes the difference of the boiling point to separate the components. The aim of this research is to develop a program can simulate the steady state of distillation column for different number of stage, feed tray location, flow rate of feed, reflux rate, heat duty. In addition, the dynamic control simulation is also provided. Microsoft Visual Basic 2010 was used to develop the program. The subprograms for solving the mass balance, energy balance and phase equilibrium equations was constructed firstly. Two temperature control loops were added into the fully program. By virtue of the simulation examples, the steady state data is similar to references and the dynamic response is also reasonable. Therefore this simulation program can be provided for further studies and research.
