Please tell me how to deal with the failure of the reflux pump at the top of the fractionation tower.

Increase the cold reflux to control the top temperature, and open an additional group for air cooling at the top of the tower.; After the backup pump is enabled, the cold return flow gradually adjusts to normal

Thank you, we only have top return flow and no cold return flow, and the question is that both pumps cannot be activated.

Catalytic fractionation column? If there is no cold return and both return pumps are malfunctioning, what is your equipment management job? Can you post a picture?

Increase the heat extraction in the middle section, reduce the reflux temperature in each middle section, and control the temperature at the top of the tower not to exceed the temperature. Reduce the reaction feed to ensure the heat load of the fractionation tower. Repair the top return pump.

Brother, do you only have cold reflux and no cyclic reflux, or are you saying that you can’t see it in this picture?

Does the catalytic fractionation column have no overhead circulation system?

Use the middle section to control the top of the tower to increase the heat extraction of each cycle at the bottom of the tower and repair it as soon as possible.

Sorry, there is recirculation, but I haven’t used it for more than ten years. I just started to learn it.* , I thought there was no one. There was a branch line across the top return line before the crude gasoline flow stabilized.
