How to deal with reduced circulation driving force in vertical thermosyphon reboilers
Thread Content
We have a distillation column here with three reboilers. The temperature of one of these reboilers is always lower than that of the other two. This time, the temperature of one of the reboilers first increased, then started to drop, and subsequently the temperatures of the other two reboilers also dropped, which led to a rapid decrease in the temperature at the bottom of the column. After taking some measures, the temperatures of the reboilers did not return to their original levels. It is suspected that the high viscosity of the material is the cause; apart from venting the liquid from the reboilers, what other solutions are there?
Is your reboiler of the vertical siphon type? Has a bench pump been added to enable forced circulation? If the material is viscous, add a circulation pump at the end to force circulation
It’s a vertical thermosyphon type. I was wondering if forced circulation can be added, and whether this would affect the operational stability of this reboiler. Also, I want to know how to do it
It’s best not to use forced circulation; try raising the liquid level instead
