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.

首先采用不同的方法分别建立了大跨桥梁索塔的精细有限元模型和简化模型，运用环境振动实测结果对简化有限元模型进行了修正，并和精细模型计算结果相比较；研究结果表明：严格按照设计图纸建立的精细有限元模型计算得到的动力特性与索塔现场环境振动实测值之间的误差较小，而未经修正的简化模型误差较大，由此说明：大跨桥梁在有限元建模时应尽可能详细地反映结构的几何与材料特性，在此前提下，对于设计资料全面的桥梁结构，建立有限元模型时就只需要修正那些无法用数学和物理方法模拟的不确定因素。
