HTRI simulation of spiral baffle heat exchangers
Thread Content
In the butadiene unit, heat exchange takes place between crude butadiene (in the tube side) and circulating water (in the shell side), using vertical spiral baffle heat exchangers manufactured by Lummus Company. The author used htri to simulate spiral baffle heat exchangers. The simulation results showed that, for the same shell diameter, the heat transfer coefficient of spiral baffle heat exchangers was lower than that of conventional shell-and-tube heat exchangers, which is somewhat counterintuitive. It’s not clear where the issue lies; I would appreciate it if experts could provide guidance and help identify the problem. (I’ve attached the file).

Although HTRI has spiral baffle modules, the calculations show a significant difference compared to those of Lummus Company. It is recommended to refer to the literature from Xi’an Jiaotong University and do the calculations by hand
