LPG Caustic Wash Column Trays Hole Size Changed
LPG Caustic Wash Column Trays Hole Size Changed
(OP)
In my facility LPG Caustic wash column trays were changed from 12.7 mm to 4 mm between 1969 - 1976, soon after commissioning and start up. we don't have any record in our data basis.
I read one report which was written 1992 that internals were changed because of corrosion.
Here is my question, why change the hole size?
Thanks

Note: you may want to contact Norton, they may be able to support. Norton may have kept a technical note about the change.
My 2 cents

New trays had different hole size from the original, so it was mentioned.
