反应-分离循环系统最佳工艺条件的确定

Optimal Process Condition of Reaction-Separation Recycle System

本文从化工过程系统综合优化的角度出发，以定态、等容反应过程为研究对象，在可得区内考虑分离回收的循环物流，通过几何方法分析总收率等值线与可得区的关系，导出了通用的反应-分离循环系统的最佳工艺条件方程。将该方程曲线与可得区相结合，可在反应器网络综合的基础上确定最佳工艺条件。采用两个等温反应的例子在两维浓度空间辅之说明。

For an arbitrary system of steady-flow and constant volume reactors, the concept of theattainable region is extended by the consideration of the recycle material from separation. The geometricmethod is used to analyze the relationship of the total yield contour lines and the attainable region, and theophmal process condition of reaction-separation recycle system is developed by system synthesis andoptilnization method of chemical concentrahon space to illustrate this problem.
