My love for building extractors (diy)

yes, it will flow easily, but at the end of the run, to clear out the column, just N2 pressure it a little to clear it.

@Boomtownpharms did u ever post the drawing of the cross flow? I do good with peectures and I’d like to see em if u got em I looked at ur posts in this thread and didn’t see em

The coils? Chemtech services makes them really tight ones they use on their wfe.

I thought you found a dude already making a similar unit with the shell.

Hell they make this…

Stack 2 of these together

Is an expansion just an intermediary holding column after the material extraction?

Condensing inside the jacket/shell of a regular common jacketed spool would make a cheap n easy xflow hx provided the shell/jacket was also sanitary(dubious)

Gets all the solvent off the material right away too!

I have one laying around I’ll never use.

If the shell is rated for the PSI, yeah it would work. Just not as efficient as a coil

I’ve been playing around with it for a while now. The setup works amazing. Defiantly worth the work and experimentation. Its acts more like a pre-condenser before your main condenser with a mix of butane vapor and liquid. I can feel solvent and vapor gurgling threw the line set exiting the crossflow condenser and entering into my coil pot. The flow rate must be throttled down to match your recovery speed or you will run out of cold solvent running threw the coil before your collection pot is recovered. I used this with a CRC so its naturally slowed down based on how much media i use. I can lower my nitrogen push PSI down to regulate flow rate or just throttle back the CRCs exit valve. I choose to just keep my regulator at 60psi and throttle back if needed. Most of the time it runs perfect wide open but near the end it speeds up after the bulk of the oil has been filtered and needs to be valved down a tad. I’ve also played around and closed off the line set exiting the crossflow condensers shell for shits and giggles. The 6x48 behaves like a recovery vessel with a coil inside and starts to fill up with solvent. I found it pretty amazing that i went from using 1lbs of dry ice per lbs of solvent to 0.75lbs/1lbs solvent recovered. My material columns are closed jacketed so i cant use dry ice in them, that is why im only seeing -35f exiting the material and entering the crossflow coil. I just use the jackets for warm water baths to recover any remaining solvent from the columns. I try to inject as cold as possible by prechilling my solvent and then running it threw the injection coil slowly. My next step with this is to cut the 1/2" bung off the lid of the coil and get a 1.5" tri clamp welded on upgrading my recovery path to 1.5" from my collection to crossflow shell. DM me and we can chat if ya need and insight.

The jacketed one Chemtek has would be better suited. I believe that its 8" shell with a 100ft coil. With a long coil like that you’d have so much surface area for condensing but im not sure its really needed or would increase efficiency seeing that im entering at -35f and exiting around 55f. I wish i had a jacked spool to use for mine because this thing sweats like crazy all day.

Thanks for the update and info @stonebolone!

Whats happening on the back side of your collection skid? I assume one is the mol sieve but cant figure the sight glassed tube?! Thanks

Mol sieve to tube in shell.
Valve in the middle is a bypass to the mol sieve

How much did bizzy charge you for that tall and skinny collection evaporator that hac two 6"tc at each end?

That wasn’t his. If it’s a column, it came from Glacier Tanks or another vendor.

In the above post he says the top half was from bizzy and the bottom nobler. I I need that peice with the gussets.

Let’s see what the man says. I swore he had that made by nboler
