Seeking expert advice: For the design of this hydrogen sulfide gas heat exchanger, a U-tube heat exchanger is being used. The known conditions are shown in the figure below. I need some guidance on the design approach; I don’t know where to start
First determine the heat exchange area, then carry out strength calculations, and finally produce the drawings
How is the heat exchange area determined? I don’t even know the outer diameter, length, or number of tubes used for heat exchange
Based on the heat transfer amount. Perform process calculations for temperature, etc
Is it to determine the heat load? If so, how are the initial and final temperatures of the cold and hot fluids determined? Please ask an expert for a detailed explanation
You can’t possibly have only this much data
It’s just this thing; I really don’t know where to start :(
Is there anyone who knows how to do this? Please give some advice{:1_90:}
That can’t be right – there are no data for the most important heat exchange tubes?
The design of heat exchangers involves two aspects: one is to conduct thermodynamic calculations on the heat exchanger in order to determine its structural configuration and appearance； Secondly, based on the results of heat transfer calculations, strength analyses and checks are performed on various components of the heat exchanger, in order to determine the total weight of the equipment as well as to prepare detailed drawings for its manufacturing and inspection.
In the picture you posted, the thickness of the cylinder is 89, while the flange thickness of the shell is 34; these two values seem problematic. The thickness of the cylinder is determined by parameters such as the design pressure and the diameter of the cylinder. If the wall thickness of the cylinder is 89, then the design pressure for the shell side should be quite high – how can the flange thickness then be only 34? In short, your parameters are incomplete, so a design cannot be carried out
