Due to reboilers fouling I noticed the deferent percentage on both reboilers affect the level controlling in both since we have only one LCV and the selector is in one reboiler.
After we cleaned one of the fouled reboilers we kept the selector on the fouled one to avoid having high level but the just cleand one becomes on low level .
Also I noticed the vapor return temp for the cleand one is relatively hi than normal I think even shell side where tube bundle is on low level . What about the weir shouldn’t be designed to make sure the bundle is submerged ?
If the equalizer is possible wouldn’t be helpful in this case and would delay the fouling time if the load is the same on both reboiler ?
I’m not familiar with engineering and design I’m operator Thanks in advance
