In what situations is it necessary to divide them into upper and lower towers?

This is related to the operating conditions and process requirements.
Does the senior know the specifics? Because I can’t determine right now whether it’s necessary to divide it into two towers
I’ve seen devices designed in such a way that the operating conditions at the top (the upper part of the tower) and at the bottom (the lower part of the tower) are different; to allow for the extraction of products or the feeding of materials, these towers are divided into two sections. Separated by two built-in end caps. I’m not exactly sure either.
The propylene column in the gas phase is divided into two sections because its height is too great; there are no intermediate products in this case.
The absorption towers here are divided into two: one for acid absorption and the other for water absorption
How tall is considered too tall? It seems the propylene tower will have around 200 layers; it is indeed tall, but I’m not sure how to determine the number at around 100 layers.:(
