Optimization and analysis of specific heat exchanger network cases
摘要
Abstract
Heat exchanger network synthesis belongs to the mixed integer nonlinear programming problem with severe nonconvex and nonlinear characteristics. In order to study some heat exchanger network cases probably existing special heat exchanger network structures with inner utilities but with lower total annual cost,a non-splits stage-wise superstructure with inner utilities was utilized. Based on the cuckoo search algorithm,an optimization algorithm was established by setting the minimum heat threshold and accepting bad network structures with a small probability to guide the structure evolution process and applied to solve heat exchanger network synthesis problems,and optimization results of the specific cases were analyzed. Three specific cases,with the characteristics of the initial temperature of the hot stream is higher than the inlet temperature of the hot utility or the large temperature difference between the inlet and outlet of the hot utility,were solved with the modified cuckoo search algorithm which found the heat exchanger networks with the inner utility and those total annual costs have a steep descent. For specific cases,the results showed that the inner utility can serve as an important role of optimizing the heat load distribution of the heat exchanger network,which save the heat transfer area and effectively reduce the total annual cost of the heat exchanger network.关键词
