Abstract: Heat exchanger network is a heat recovery system in a industrial plant,which plays an important role in reducing energy consumption and increasing energy utilization ratio. The design method for heat exchanger network has been one of the hot worldwide research subjects. In last 30 years,many research studies by domestic researchers have been carried out on this topic. Based on the reports published in China,the domestic progress in the field of synthesis method is introduced. After a review of several groups of approaches,such as pinch design methods,mathematical programming methods and optimization algorithms,the main research contents and difficulties are analyzed and summarized. Finally the main researching focus and developing direction on simultaneous synthesis method and global optimization algorithm are pointed out to improve theoretic study and practical application.

Key words: heat exchanger network, pinch design method, mathematical programming, optimization algorithm
