In order to overcome this drawback, various novel ideas and approachES have been proposed in literature. The subject of this work is on the design of internal energy-integrated distillation system.tudies on internally heat-integrated distillation column(HIDiC) are proceeding for many years. HIDiC was proved to be effective in energy saving, but so far only few works addressed about its economic point of view and “asymmetric” structure. This work aims to develop a general model of mixed-integer nonlinear program (MINLP) for HIDiC design where exergy consumption and total annualized cost (TAC) are both taken into account. After the optimization, the results of asymmetric HIDiC are compared with those of conventional distillation column and symmetric HIDiC in the two aspects (exergy consumption and TAC). The follow-up analysis shows how the structure of asymmetric HIDiC to influence the energy efficiency and total cost.摘要 i謝 iii要 vbstract vii圖目錄 xiii表目錄 xvii. 緒論 1.1 前言 1.2 HIDiC之原理與結構介紹 2.3 文獻回顧與當前之技術背景 6.4 研究動機與目的 9 .5 組織章節 10. 內熱整合蒸餾塔逐層式超結構模式建構 11.1 模式建立之背景說明 11.2 模式建立之基本假設條件 12.3 設計流程之介紹 14.4 模式之符號、集合、系統參數與系統變數(Indices, Sets, Parameters, and Variables) 16.4.1 符號說明(Indices) 16.4.2 集合說明(Sets) 17.4.3 系統參數(Parameters) 18.4.4 系統變數(Variables) 20.5 目標函數與限制式(Objective Functions and Contraints) 20.5.1 0-1變數決定塔板數限制式(Binary Representation of Column Trays) 20.5.2 質量及能量平衡限制式(Mass and Energy Balance Constraints) 21.5.3 邏輯限制式(Logical Constraints) 31.5.4 莫耳分率限制式(Mole Fraction Constraints) 32.5.5 單調增減限制式(Monotonic Constraints) 32.5.6 熱力學關係式(Thermodynamics) 33.5.7 規格限制式(Specification Constraints) 34.5.8 氣體與液體莫耳熱焓量計算式(Vapor and Liquid Molar Enthalpy Calculation) 35.5.9 蒸氣再壓縮機設計方程式(Compressor Design Equations) 35.5.10 塔結構限制式(Column Structure Constraints) 37.5.11 年總成本計算式(Total Annual Costs Calculation) 39.5.12 目標函數(Objective Functions) 41. 模式之實例暨模擬結果分析與討論 45.1 最佳化軟體介紹 45.2 苯與甲苯分離系統與基本性質之介紹 46.3 苯於甲苯最適化設計 49.3.1 目標函數一:最小化外部提供有效能(Exergy) 49.3.2 目標函數二:最小化年總成本(TAC) 61 .4 非對稱內熱整合蒸餾塔(asHIDiC)架構討論 71.4.1 比較asHIDiC在最小化有效能與年總成本下的設計架構 71.4.2 asHIDiC板數對最適化結果之影響(Min.
