What size should the base be for a passive closed loop with a 3 inx24 column? I can get either a 6 inch with a spool and a splatter platter, or a 10 inch.

Im in contact with a manufacturer to get this-
https://www.alibaba.com/product-detail/3A-Approved-SS304-Food-GradeTriClamp-Spool_60410550301.html?spm=a2700.7724838.2017115.14.pZVGhQ But with a big triclamp on the bottom and a splatter platter.

It will eliminate a big expensive clamp/gasket/weakness, and it has the ring to protect the valves. Notice that its a min buy- I may go into the extractor biz? And so nobody gets confused it doesnt really cost 10 dollars, itll be at least 150 shipping each.

I run a 10"x15" collection vessel which is including a 3" shatter platter for a 4"x48" column with 4" to 2" concentric reducers which brings the column to a 678 cubic inch volume or 11.11 liters. I can use roughly 20 lbs of a 70/30 butane/propane mix, which is 1.31 lbs per liter, per pass which fills my collection pot to an 80% full mark. It would be nice to be able to run 25 lbs but this works for me. The bigger you go, as far as triclamps go, the less pressure they can handle. I have heard of 12" lids being leaky, not that I haven't had a small leak myself.. that's just one of the many variables to running a closed loop.

An important point if you are operating a certified facility, is that the pressure vessels be certified to ASME Section VIII. Also a capital idea that it meet those standards, even if you aren't operating a licensed lab, for safety's sake.

6" and below is considered pressure piping and must meet 350 psi for LPG. Everything above is a pressure vessel and must meet 3X its maximum operating pressure.

Also consider that if you are transporting LPG in it, it will require both ASME and DOT certification.
