Main contributions and achievements are as follows:A general non-equilibrium rigorous model for RDP is developed in this thesis. Based on the pseudo-homogenous assumption, two main factors reaction and separation are de-coupled, and an RDP model with the same format as that for a traditional distillation process is established. To solve the model with a large number of algebraic equations, modified M-K equations with tri-diagonal matrix form are developed based on the improved Separation Efficiency Functions, which greatly increases the iteration efficiency. This thesis also develops a general reactive distillation dynamic model. Through splitting of the differential variables based on SEFS, large-scaled differential algebraic equations can be solved with the improved Gear's algorithm which makes the dynamic model suitable for the on-line application. A simulation platform for the control loop design and evaluation of RDP by introducing control system equations into the dynamic model is also developed.A lactic acid purification pilot-scale RDP is investigated.

论文对热点问题——反应精馏过程的建模与优化控制相关技术进行了深入的研究,取得了一系列成果:1、建立了反应精馏过程机理模型,基于拟均相假设,将反应和分离过程进行解耦,推导出反应精馏过程的非平衡级稳态模型和动态模型,通过引入推广的分离效率函数,对模型变量进行了合理划分,显著提高了模型求解效率;将动态模型和控制系统方程结合,建立了反应精馏过程控制系统研究的辅助工具。2、全面分析了乳酸提纯反应精馏新工艺试验装置,利用本文建立的过程机理模型,对该试验装置进行了稳态和动态性能分析及水力学核算;设计和分析了单边质量控制方案,比较了间接和直接物料平衡控制两种方案的控制性能。

It thinks that the promotion of ESO system is the requirement to deepen the current state-owned enterprise reform and the construction of modern enterprise system. It is urgently needed by the hi-tech enterprises to attract talents and avoid brain drain. The long-term stimulation mechanism such as stock option has better effect in comparison with the traditional salary mechanism such as basic wage and annual bonus. Meanwhile, with the expansion of use scale of the long-term stimulation mechanism such as stock option and greater elasticity of the performance of the whole salary, the stimulation effect of the whole salary will be strengthened.

认为ESO制度的推行是当前深化国有企业改革,建立现代企业制度的要求,是高科技企业吸引人才、避免人才流失的迫切需要;其与基本工资和年度奖金等传统薪酬机制相比,股票期权等长期激励机制的激励效果更好;同时随着股票期权等长期激励机制使用规模的扩大,整体薪酬的业绩弹性增大,使整体薪酬的激励效果增强。
