tray damage in distillation column

[Siddz]

Hi, hope you all are fine.
I have a question is that , crude ditillation column is open after four years. All trays is in good condition but the drawoff of kerosene plate is damage even its not able to use much more what was the purpose of this damage in kerosene plate .

Strange why only this drawoff tray is damaged. Drawoff going to side stripper ? Can we see P&I D of this section of the column and side stripper or pump around ?? What about photo of damaged tray ? Corrosion or mechanical buckling of tray ?

Could you share a photo of the damages ?????. Mechanical damages to only one draw-off could be done in the last maintenance work.

georgeverghese yes draw off is going to stripper and dont share P&ID because its confidential , but i share the tray photos as soon as possible

Open after 4 years, but was there any maintenance work on this CD column before that ?

Is this column the first column sometimes called topping unit, or this is the next vacuum distillation unit ?

If after four years, only the kerosene plate drain has been damaged, you should be proud of the operation of the atmosfheric column by your operators. These types of plate-damaging incidents occur during unit starts and stops, due to pockets of condensed water and their sudden expansion and consequent explosion of the trays.
