Partition Strategy of Non-isothermal Reactor Networks Synthesis Based on Instantaneous Objective Function

摘 要 :反应器网络综合是化工过程综合的关键子课题之一。本研究以反应器系统为对象,以停留时间(或空时)为目标,针对稳态、恒容、非等温条件下的化学反应过程,在瞬时反应速率r和关键反应物的未转化率x空间探讨了反应、混合、温度对反应速率的影响,提出了在r x空间非等温反应器网络综合的新策略。以第一类反应中的可逆放热反应为例,利用得到的分区策略,获得了在非等温操作条件下的最优反应器网络。

The synthesis of reactor network is a key sub-problem in the synthesis of chemical process. The effect of reaction, mixing and temperature on reaction rate in the space of instantaneous reaction rate-unreacted main reactant was studied using retention time as an objective, and a new strategy for the synthesis of reactor networks was presented under steady state, isochoric and non-isothermal anditions. Also, according to the obtained new strategy, the optimal reactor network of reversible exothermic reaction was obtained.
