I am working on a 4" design using 3 sets of 3 plates, so 9 plates all up in a 1800mm column with 250mm dephlegmator. I want to stack the plates in from the bottom and have the bottom set of plates sitting or fixed to the bottom flanged end cap and the next set of plate stacked above and so on.
You will have to imagine the 4" column in the drawing
This is not my idea. I don't remember where I saw it, sorry in advance for the lack of credit to who ever I stole the idea off.
I plan to use (6-8) 1/2" & 1" end caps for the bubble caps per plate. The outer cap screwed to the inner cap like the AC are.
What size holes and how many should I use on the out caps?
I thought I would solder the 1/2" cap to the plate.
I was thinking a 3/4" downcomer would do the job?
The downcomer liquid would exit on a 3" plate to rain over the bubble caps. There is a weir at the tube exit.
What have I forgotten?
Ideas?
