Contrast sharply to the conventional distillation process, the reactive distillation process can offer more benefits in utility consumption and capital investment. The main object of this paper is to activate the potential advantage of the reactive distillation columns in the chemical process industry.In terms of the ratio between the thermal heat released by the reactions involved and the latent heat of the reacting mixture separated, reactive distillation columns can be divided into three broad categories, ., those with highly thermal effect, those with considerably thermal effect and those with negligible or no thermal effect. Though a number of methods have already been proposed for the synthesis and design of reactive distillation columns so far, much of them are actually about the process with highly thermal effect, and almost no essential progress has been made regarding the synthesis and design of reactive distillation columns with negligible or no thermal effect.A systematic method for deepening internal mass integration is proposed for the synthesis and design of reactive distillation columns involving reactions with negligible or no thermal effect, aiming to improve the thermodynamic efficiency. Four strategies, including the superimposition of reactive section onto rectifying and stripping sections, relocation of feed stages, and redistribution of catalyst within the reactive section, can be derived to intensify internal mass integration. With a systematic application of these strategies, a sequential procedure is devised for the synthesis and design of reactive distillation columns involving reactions with negligible or no thermal effect.Four hypothetical ideal reactive distillation systems are used as examples to evaluate the philosophy proposed, and a substantial reduction of utility consumption is secured in addition to a further abatement in capital investment. The proposed method for deepening internal mass integration could be effective in different reactive distillation models with different physical properties and operating conditions. It is also proved quite simple in principle and procedure. These striking results evidence the significance and strong necessity of deepening internal mass integration in the synthesis and design of reactive distillation columns.Keywords: Reactive distillation column, thermodynamic efficiency, internal mass integration, process synthesis, process design目 錄符 號 說 明 1第一章 緒論 3 3 3 4第二章 反應精餾過程簡析 5 5 5 5 6 動態(tài)模型簡介及研究情況 6 多穩(wěn)態(tài)現(xiàn)象 7 8 9第三章 強化內(nèi)部物質(zhì)耦合 11 11 11 13 14第四章 理想四元反應精餾體系A(chǔ)+B?C+D 15 A+B?C+D反應精餾體系過程描述 15 15 18 24 FB進料熱狀況對系統(tǒng)穩(wěn)態(tài)特性的影響 24 25 小結(jié) 27第五章 雙進料的理想三元反應精餾體系A(chǔ)+B?C 28 A+B?C反應精餾體系過程描述 28 28 31 34 FA進料熱狀況對系統(tǒng)穩(wěn)態(tài)特性的影響 34 36 小結(jié) 37第六章 理想三元反應精餾體系A(chǔ)(HK)?B(LK)+C(IK) 38 A?B+C反應精餾體系過程描述 38 38 40 46 FA進料熱狀況對系統(tǒng)穩(wěn)態(tài)特性的影響 46 47 小結(jié) 47第七章 理想三元反應精餾體系A(chǔ)(IK)?B(LK)+C(HK) 48 A(IK) ?B(LK)+C(HK)過程描述 48 48 50 55 FA進料熱狀況對系統(tǒng)穩(wěn)態(tài)特性的影響 56 56 小結(jié) 57第8章 強化系統(tǒng)內(nèi)部物質(zhì)耦合的討論 58 58 58第9章 結(jié)論與展望 61 61 展望 61參 考 文 獻 63致謝 69研究成果及發(fā)表的學術(shù)論文 70作者與導師簡介 71ContentsNotation 1Chapter 1 Introduction 3 The Development of Reactive Distillation Process 3 Advantages and Research Necessity of Reactive Distillation Process 3 Structure of This Paper 4Chapter 2 Research of Reactive Distillaiton Column 5 History and Plant Process of Reactive Distillation 5 Concerning Reactive Distillation Models 5 Steady State Model 5 Dynamic Model 6 Research of Dynamic Model 6 Multiple Steady State 7 The Category Method according to the Thermal Effect 8 Intensifying Methods Improving System Performance 9Chapter 3 Deepening Internal Mass Integration 11 The Method of Deepening Internal Mass Integration 11 Four Strategies 11 A Sequential Procedure 13 Conclusion 14Chapter 4 A Hypothetical Quaternary Reactive Distillation System (A+B?C+D) 15 Process Description 15 Steady State Model Description 15 Effect of Deepening Internal Mass Integration 18 Influences of Physical Propoties and Operation Condition 24 Influences of Thermal Conditions of FB 24 Influences of the Amount of Catalyst Employed 25 Conclusion 27Chapter 5 A Hypothetical Ternary Reactive Distillation System(A+B?C) 28 Process Description 28 Steady State Model Description 28 Effect of Deepening Internal Mass Integration 31 Influences of Physical Propoties and Operation Condition 34 Influences of Thermal Conditions of FA 34 Influences of the Amount of Catalyst Employed 36 Conclusion 37Chapter 6 A Hypothetical Ternary Reactive Distillaiton System with a Heavy Reactant A (HK)?B(LK)+C(IK) 38 Process Description 38 Steady State Mo
