RSR系统一般化特性方程

The general characteristic curve eqution of RSR system

从过程系统综合优化的角度出发,针对反应器/分离器/再循环系统,基于反应、混合和分离操作的基本原理,将反应器系统由纯组分进料拓展到任意组分浓度进料的情况,同时考虑产物与反应物不能完全分离,采用几何图示的方法,在二维浓度空问分析了总收率等值线与可得区的关系,导出了RSR 系统的一般化特性方程。将该特性方程曲线与可得区相结合,可在明确反应器系统流程结构、反应器类型的基础上确定RSR 系统最佳工艺条件。结合实例分析了反应器/分离器/再循环系统特性曲线的构造方法,考察了未反应物回收率m 值以及反应器系统进料点对RSR 系统一般化特性方程的影响。

From the view of systemetic synthesis,this paper,based on the principle of arbitrary reaction and mixing,extend AttainableRegion method from reactor system to reactor-separator-recycle system by consideration of the recycle material from the separation.Atthe same time,considered of the different separation condition of product with reactant and side-product,this article analyzes the rela-tionship of the gross yield contour lines and attainable region by geometric method and deduces the general characteristic eqution.Atthe end of this article,the method of general characteristic curve eqation is constructed by analyzing the vàn de vusse reaction.
