What is the purpose of that N-shaped device placed after the tubular reactor?

As shown in the figure, what is the function of that red N-shaped element? How should this thing be called? If we want to add that height, how do we determine it?
Could any older brother or sister who knows about this get in touch?
The pipeline you drew (the N section) isn’t connected to any equipment or control valves, etc. Based on my past experience, this was likely designed intentionally; perhaps the vapor from the top of the distillation tower needs to be discharged after passing through a heat exchanger (to prevent uncondensable gases from causing an increase in tower pressure and hindering flow). Just letting you know
What is connected there isn’t a heat exchanger; it’s a fixed-bed reactor. Designing an N-shaped pipe shouldn’t provide the same liquid-sealing effect as a heat exchanger, right? There must be other functions as well; he also requested a specific design height
It should be a liquid seal; indeed, there is a requirement regarding its height. As for other functions... it’s not clear what they are. Additionally, this pipeline should also have an exhaust line, otherwise any accumulated gas won’t be able to escape
There is indeed that line you mentioned, but I think that line is connected to the venting system; if gas is released, it would be easy for liquid to be carried out, right? How do you usually handle it?
Basically, that exhaust connection pipeline is used for discharge only during the initial startup of the system; once the system is stable, this process no longer occurs. So, during the initial startup, if there is pressure that cannot be properly discharged or if the flow rate fluctuates greatly, you can try carrying out a discharge to see what happens
Many of these pipelines here serve a liquid-sealing function; if used behind the reactor, they should be able to control the reactor’s liquid level and thus prevent overflow.
