摘要
提出了有分流结构特征的换热网络同步综合数学规划方法。该方法以Yee和Grossmann提出的分级超结构模型为基础,在工艺物流匹配过程中考虑分流串级结构,建立混合整数非线性数学模型,采用无进化次数的改进粒子群算法进行求解。两个典型算例用来验证方法的可行性和有效性。
A general method for simultaneous synthesis of heat exchanger network with split streams is proposed,which is formulated as a mixed integer nonlinear programming model based on stage-wise superstructure.An improved particle swarm optimization is proposed for optimizing such systems.Two benchmark problems are studied to prove that the proposed method is able to find more economical networks than those generated by other methods.
