摘　　要：质量交换网络是过程系统高效经济回收污染物或杂质的重要途径,其中组分浓度的小尺度特征对于其求解域和全局优化性能存在一定限制。基于质量传递和能量传递比拟理论,本文假设了单位高度塔板提供有效传质的塔板质量,建立了非连续传质的板式塔和广义换热器的比拟关系;在此基础上,将小尺度质量交换网络比拟为广义换热网络,进而采用节点非结构模型和强制进化随机游走算法对广义换热网络进行全局优化;最后,将优化所得的广义换热网络回归为质量交换网络,使其满足传质可行性约束。算例分析表明,该方法可有效拓展质量交换网络搜索空间,提升流股匹配的多样性和全局优化性能。同时,灵活调整比拟尺度和协调系数能够进一步丰富优化路径,提升最优解的质量,获得了R2S3算例和R2S2算例优于文献最优的结构。Mass exchange network is an important way to recover pollutants or impurities efficiently and economically in process systems,the small-scale characteristics of which have certain limitations on their solution domain and global optimization performance.Based on the theory of mass transfer and energy transfer comparison,this paper assumed the tray mass providing an effective mass transfer of per unit height tray,established the comparison relationship between tray column tower and heat exchanger.On this basis,the small-scale mass exchange network was analogized to the generalized heat exchanger network.Furthermore,the node-based non-structural model and the random walk algorithm with compulsive evolution were used to globally optimize the generalized heat exchanger network.Finally,the optimal generalized heat exchanger network was regressed to mass exchanger network to make it satisfy the mass transfer feasibilities.The example analysis showed that the method can effectively expand the search space of mass exchanger network,thus to improve the diversity of stream matching and global optimization performance.Meanwhile,flexibly adjusting the analogy scale and coordination coefficient can further enrich the optimization path of MEN,and improve the quality of the optimal solutions.The obtained optimal solutions for the R2S3 and R2S2 examples were both superior to the best solutions in the literature.
