Does a structured packing tower require a discharge port?

Does a structured packing tower require a discharge port? The packing is P-125 ii. According to the drawings, in a packing tower with a diameter of more than 4 meters, a discharge port is provided at the lower part of the packing layer; it seems that regular packing cannot be removed from there.

Regular packed towers generally also require a discharge port; a manhole that doubles as a discharge port can be used
Structured packing does not require discharge through a discharge port, and it is also not convenient to remove the material from such a port. The so-called discharge port on that tower indicates that it was probably previously equipped with bulk packing, or it was used for some other purpose.
“Providing a manhole that also serves as a discharge port in a structured packing tower is ineffective in actual production.
Thank you to the friend upstairs! The packing layer of this tower is 5 meters thick. From the drawings, it appears that there is a difference of about 1 meter between the height of the discharge opening on the upper layer and that of the manhole on the lower layer; the platforms are shared. It seems feasible to use the manhole as both a discharge opening. Could you explain the situation regarding production as mentioned by the colleague on the 4th floor? Thank you first!
A suitable manhole will do
Regular packing is rarely replaced; if replacement is necessary, it is done by shutting down the system, and there is no need for a discharge port.
Regular packing is of course removed and installed through the manhole, while bulk packing (such as Pall rings, saddle rings, etc.) is equipped with discharge ports to facilitate unloading
Regular packing generally does not require a discharge port, as it is of little use. If the structured packing comes out from the discharge port, it is very likely to get scattered.
Structured packing does not require a discharge port. You should know that structured packing consists of individual pieces that are stacked together in layers, just like bricks. You install them from the bottom up, but to remove them, you can only do so from top to bottom; otherwise, it’s impossible to remove them. It’s similar to trying to take bricks out from the bottom – it’s definitely not possible.
Is it usually unloaded directly from the manhole?
Regular packing is divided into separate pieces, with the size of these pieces generally being determined by the ability to access them through the manhole During installation, proceed layer by layer according to the sectional diagram! With a discharge port, I think this tower might have been modified; it was originally equipped with bulk packing, which is why this situation occurs!
