The application of shell-and-tube heat exchanger is extensive, and the optimization design is particularly important. The performance efficiency of the heat exchanger is influenced by its own structures and numerous operating factors. The optimization design mathematical model established with the objective function of annual total cost has strong nonlinearity. In this paper, the optimization algorithm of the lstOpt software platform is used to optimize the process. The results showed that the lstOpt optimization system can provide efficient solution for the model optimization scheme. The optimum design model and algorithm are in accordance with the engineering practice and wide applications, which can achieve better optimization design of shell and tube heat exchanger and save produc- tion and design costs for enterprises.
