The column with the gussets was made by NBOler. The BizzyBee parts were the lids, sight glasses. The lid for this one piece, which I commissioned through IndoFab, was a 6” lid with a 3/8” port for PRV and gauge, a 1/2” port for liquid input, and a 1.5” Tri clover port for exhaust.

While that collection bowl was nice, if I were to do it over again, I would pay the extra $100 I think it was to go with a bizzy bowl. But they both work good for the process.

What was your thought process/reasoning for choosing the thicker end caps on this system? Are they rated for propane while the thinner caps are not?
It would not be the caps. The weakest point of any LPG system are the clamps. This is why quality fabrication is important in keeping those ferrules faces perfectly flat after welding. If you’re running propane, you will want 8" or 6" clamps at most unless using a rated manway. Of course, any vessel over 6" will require a U or UM ASME stamp to be compliant.

Why aren’t any coils like this mounted with the fittings in the side of a very short spool? Id like a
6”x2” spool with 6” coil.

Exactly. It would have to be custom made.
But if one can get it done, the savings from dry ice or chillers power would have great effects on your bottom line.

How big is that NBOler column with the gussets? Did you have that custom made by them?
It’s 10” in diameter on the inside. The ends are 6”. About 52” in height

Just bumping up a good thread.
@Boomtownpharms How are you doing lately?
Do you have any diagrams of how the crossflow heat exchanger works?
Lots of people probably haven’t heard of this yet.
Great idea by the way!

Gearing up for my move back out West.
I try to draw it out the best way I can when I get home, but it’s basically a column, preferably 4x36”. Bottom of column would have a 1/2” connection going back to the solvent tank. The top, will have a 1.5” or larger tri-clover fitting. The bottom side of the column, needs a 1/2” port to connect to the inside of column containing the coil that leads to the upper side port leaving the column heading to your collection column. The top port, accepts gas coming from your sieve column. The bottom side port accepts cold solvent coming from your extraction columns.

It’s brilliant and I want one or two of my own.

Ive been using one for about a year . Ive been able to cut dry ice use down by 30% potentially a little more . My system is all passive and runs fully off dry ice and one baby chiller so this is huge for me . When i keep the heater turned down the system almost runs itself i barely have to add ice. It really helps make your system more efficient and can increase recovery as well . I have acheived delta temp swings of 50c+ sometimes when its really working well

After as much as I have already given away on this subject I cannot believe you are still struggling with the concept… 
It is just an extra condenser column put inline before the actual condenser that exchanges heat with what is no longer needing to be cold (extraction solvent) as it travels to the basin. No need to restrict flow if it is done right. Nothing “special” needs made here.
You take the liquid from the extraction column drain and run it through the tubes in the core of the condenser and the hot vapor around the tubes in the shell. The hot vapor condenses on the cold liquid removing the need for dry ice.

With all of our extraction systems, all heat required to operate the system is generated by the system, just as nearly all cooling required to operate is also generated by the system and still achieves above +50c and below -50c conditions. (Patent Pending)
There is only one condition where we still use a small MTA chiller (for now), but other than that - the system runs the system.

I approve @Zack_illuminated systems. I do feel he is the forefront of the extraction systems out there for hydrocarbons.

Agreed. Most everything else is more of the same.
