What was said upstairs is right too; it probably isn’t completely blocked. What is the temperature at different heights of the tower? Has it gotten hotter? Remove the insulation layer and touch it with your hand to see if it’s hot. Without an insulation layer, the internal backflow is severe.
From the top of the tower to the inlet of the condenser, there are areas where moisture can accumulate, areas without insulation, or sections where the insulation has been removed; feel those areas with your hand to check if they are hot.
That’s not a reboiler issue. Hot gas has gone up there as well. Is the cooling capacity of the condenser sufficient?
A gas-liquid separator should be connected below the condenser, and this gas-liquid separator must be linked to the gas channel at the upper part of the condenser. It’s the balance tube. Is the vapor-liquid separator hot? If it is, the cooling capacity is insufficient. There is a certain height difference between the vapor-liquid separator and the inlet of the reflux pipe into the tower, which should be around one to two meters. Could the liquid outlet of the condenser get clogged?
Wow, it uses a pump to do that – the pump sucks up all the material. It went back to the reflux stage, so of course there was no outflow. A height difference of about ten meters should be more than enough. It can reflux on its own. By the height difference of about ten meters you mentioned, do you mean the difference in height between the outflow flow meter and the inflow port, or rather the difference in height between the outflow flow meter and the condenser? The height difference between the condenser and the inlet of the reflux tower should not be around ten meters. Is your tower very tall?
