摘　　要：提出了以有效能损耗最小为目标、同时又考虑热集成的多组分复杂精馏塔序列优化设计新策略。该复杂精馏塔模型:1股进料、2股出料,每块理论板上均可有中间冷凝器或再沸器。复杂精馏过程的设计步骤是:①根据过程有效能最小确定优化塔序列;②对每个塔优化设计出含中间换热器的复杂塔;③考虑多效且允许热集成的复杂精馏流程,以塔压为决策变量,以精馏过程有效能损耗最小为目标,建立并优化设计出一个热集成的复杂精馏流程。一个3组分精馏过程的例子表明所提策略简单有效,可用来指导多组分精馏过程的优化设计。A new strategy to design an multi-component complex distillation process was presented,which was Daseu on the minimum exergy loss and involved heat integration within a series of complex columns. The complex column is limited to one feed, two products, with the side reboilers or condensers being allowable for each stage. The new strategy is composed of following steps：Determinating the optimal series of colmums based on minimum exergey loss of the process . Each column is optimized to obtain the complex column with side reboilers and condensers based on minimum exergy loss. （~） Constructing and designing an optimal complex distillation process with heat integration and multi-performance, taking the operation pressure as decided variables and exergy loss of the distillation process as objective function. An example of three components distillation was given to show that the new strategy can be used easily to design the optimal multi-component distillation processes.
