There is a connecting pipe between the discharge pipe of the distillation column and the feed pipe of the reboiler

As the title suggests, the diagram shows that the outlet pipe from the reboiler and the inlet pipe to the reboiler are two separate pipes. However, there is a connecting pipe between them that doesn’t have any valves; its diameter is the same as that of the reboiler’s inlet pipe. What is the function of this pipe? Is it to control the flow rate of the reboiler feed line?
This connecting pipe is usually referred to as a balance pipe or bypass pipe. Its main function is to establish a material flow path between the reboiler outlet pipe and the reboiler inlet pipe of the distillation tower. Due to the absence of valves, this design can be used to balance the pressure on both sides and ensure stable material flow. At the same time, this connection can also help control the flow rate in the reboiler feed line, ensuring the continuity and efficiency of the material processing during distillation. However, the specific function needs to be analyzed in conjunction with the operating conditions and design requirements of the entire system. .
The drawings are confidential; since they are relatively simple, a written description is provided: there are two pipes at the tower’s discharge point – one for product discharge and another for feeding into the reboiler. There is also a pipe connecting these two pipes, and its diameter is the same as that of the pipe leading to the reboiler
It’s still pretty good, isn’t it? Haha
Let’s check the location on site? It seems to be intended to empty the reboiler when the system is shut down!
No problem, this is just a standard design

Is it forced circulation or thermal siphon?
So what is the meaning of this design?
