The stage-wise superstructure model of shell-and-tube heat exchanger network without stream spits was proposed, objective function and constraint conditions of the heat exchanger network were obtained, an optimization example was given using improved particle swarm optimization algorithm with position weighted. The result shows that, through choosing appropriate weighting factor, improved particle swarm optimization algorithm with position weighted can accelerate the algorithm’s convergence velocity, and can obtain global optimum solution, at last the best optimization parameters of hell-and-tube heat exchanger network can be obtained.
