The centring cone wont make much if any difference overall, you would have to be very unlucky to have the packing arrange itself so that there was a clear path straight down the side of the column
Given that you are in Vic, scoria is not a bad choice of medium vs scrubbers, its very cheap down there and many will argue it dose an equal or better job, many just use fresh stuff instead of cleaning it as its $35 a trailer load down there
Having 3 different mediums in the column will be inefficient as the column will have to balance out to the "weakest" one, also having "dead space" between sections just wastes height that could have packing in it (top of column 2 in your pic)
It would be much cheaper to have the packed section as a single 1.4m length (or as much height as you can get into your stilling area), those triclamps aint cheap and attaching them aint the easiest thing unless you have the tig available to do it properly yourself
Why all the plates? and the different hole szes? The one with 5mm holes would come close to loading at full tilt in a 4" packed column
If you just want to retain the packing some woven SS mesh is much easier to use and way less restrictive
Each unnecessary restriction adds to the amount of power you have to use and raises the the temp of the boiler, which in turn means to achieve the same level of separation (quality vs smearing), you have to reduce output speed. I am only talking very small percentages here, but given how many times its likely to be run, becomes hours/days of your life over a span of years of runs
