摘要
针对定态、恒温、等容反应过程,将二维浓度空间中反应/分离/循环(Reactor-Separator-Recycle,RSR)系统的最佳工艺条件方程拓展至瞬时选择性(S)—关键反应物未转化率(x)空间,在一定程度上克服了浓度空间的维数限制。以Van de Vusse反应模式为例,分析了关键反应物转化率、未反应物的回收率以及产品分离程度对RSR系统最大总收率的影响,获得了最佳CSTR—分离器—循环结构及其最佳工艺条件。
For the reactions of steady state,isothermal state and constant volume,the optimal processing condition equation of reactor-separator-recycle（RSR）system in two dimensions concentration space was extended to the instantaneous selectivity-unreacted fraction space of key reactant（S-x）to overcome,to acertain extent,the dimension limits in concentration space.For example of Van de Vusse reaction,it was analyzed that conversion ratio of key reactant,unreactant recovery fraction and product seperation degree influence on the optimal yield in RSR system and the optimal CSTR-separator-recycle framework and its optimal prcess condition were obtained.
