I would like to ask how the feed position in a floating valve tower is determined

I would like to ask fellow sea veterans: our MDEA solvent regeneration tower uses feed at the 1st and 3rd layers, with an emphasis on the desorption efficiency of the MDEA-rich amine solution. However, I don’t understand why feed is not supplied from the 1st and 2nd layers or the 2nd and 3rd layers of the tower How is the feed position chosen for a floating valve column (I’m not sure whether the choice of feed position is related to the type of column)? Thank you all for your answers!

I have seen MDEA regeneration towers that use packing throughout, with feed at the bottom of the tower.

Are you saying that the solvent regeneration tower uses a packed tower? The processing capacity must not be very high, right... What type of filler is being used?
