We study two new challenging problems in distillation network synthesis: (1) how to synthesize a distillation sequence when streams can have variable, including zero, component flows, which is common when the distillation network is simultaneously designed with the reactor network, and (2) how to couple the reactor and distillation networks, especially when there are multiple coupling streams. We introduce a superstructure-based method for distillation sequence synthesis using a “matrix” representation. We use binary variables and mixed-integer constraints to determine the separation task for each distillation column accounting for the possible zero component flows. Departing from existing methods, the proposed approach yields the optimal coupling configuration of distillation and reactor networks.

基于上层结构的方法扩大了蒸馏网络综合的范围

我们研究了蒸馏网络合成中的两个新的挑战性问题:(1)当物流具有可变的组分流(包括零)时,如何合成蒸馏序列,这在蒸馏网络与反应器网络同时设计时很常见;和(2) )如何耦合反应器和蒸馏网络,尤其是在有多个耦合流的情况下。我们介绍了使用“矩阵”表示法的基于上层结构的蒸馏序列合成方法。我们使用二元变量和混合整数约束来确定每个蒸馏塔的分离任务,并考虑可能的零组分流量。与现有方法不同,所提出的方法产生了蒸馏和反应器网络的最佳耦合配置。
