Abstract: As an efficient heat exchanger, shell-and-tube heat exchanger was widely used in petrochemical production, and the conventional design way is very complex. The heat exchanger design software has gradually replaced the traditional calculation method, and has become the main design method for engineers and manufacturers of heat exchangers. In this paper, the steam condenser containing non-condensable gas H₂, CO, N₂ is designed, and described the process designing and verifying the shell-and-tube heat exchanger by discussing an example of using Aspen EDR software. The selection of parameters and the emphases in the synthesis gas are emphatically introduced. Besides, the problems encountered in the design were analyzed, and the adjustment strategy was determined. Finally, the design meets the requirements of the process. Using ASPEN EDR software to design the shell-and-tube heat exchanger can save a lot of manual calculation process and improve the efficiency of the designer.
