Researching Methods of Design of Continuous Reactive Distillation Processes

介绍连续反应精馏过程设计的两种研究方法 :静态分析法和有限元正交搭配OCFE法 .静态分析法是对反应精馏图进行热力学和拓扑学分析 ,鉴定反应精馏过程的基本可能性 ,此方法不需要依靠确定的对象的特性 ,要求最少量反应混合物的物理化学特性 ,有限元正交搭配技术应用了把整级评估模型转变成连续的模型 .OCFE能精确地吻合逐板模型的优化设计 ,而只是使用一套较小的模型公式和避免使用与塔级数有关的总决策变量 .用静态分析寻找一个最大转化率稳定态 .用OCFE确定反应精馏塔的级数 (塔级数 )及进料级 (塔板 )位置 .

Tow researching methods of design of continuous reactive distillation processes are addressed in this paper Analysis of statics and orthogonal collocation on finite elements(OCFE). Analysis of the statics is a result of their thermodynamic and topological analysis of the structures of the distillation diagram.With this tool, the basic potentials of the process can be indentified tool are being a general method with no dependence n concrete features of the object and requiring minimal information of the physicochemical properties of the reaction mixture OCFE techniques that transform the integer-valued stage model into a continuous analogue are employed OCFE models accurately reproduce the same optimal design as a full-order tray-by-tray model White using a smaller set of equation and eliminating the use of integer variables associated with the column stages To find maximizes the conversion steady state for a given feed composition with an analysis of the statics and to determine the total the number of stages in the reactive column and the locations of feed stages with OCFE.
