But yeah you screw the male of PRv into the t fitting female then t fitting male into pot, extra female opening for gauge
SS 1/4" male double female… That one looks funny to me like cast, might work idk
Go up to @BG305 post above us
…top pic…the male pointed down, females on each end
I can’t find on eBay, I get from my supplier of all… Killa
Can you give me a list of parts to ask killa?
U don’t need but the t fitting though right?
Idk if he has prvs…that’s the best one to get to vent somewhere else if it does
Tank regulator lines…
Ur tank needs the same get up as pot
Oss nitrogen push walk through
Beautiful!!!
That fog is what i look for in the sight glass under my material column to know that i pushed all the solvent out of my material. Thats when i close the Nitro and purge it.
I don’t know your rig or style but you should use the nitro to push everything into your collection, and then recover.
It is safe if used with a regulator and close attention to your system.
I have no PRV’s on my system but never have the pressure within expand beyond what the regulator is set to (40-50 psi). I run below -50 and do not begin recovering or introducing heat until I have bled off the nitrogen from tops of any columns + collection. I pump nitro in continuously until it comes out in collection - and then close collection, bleed collection, and open again to push the last bit out. Since I stay cold enough I just release pressure to 2-3 psi and like @BG305 said look for the fog in the collection - close it up once I feel like I got everything and then recover.
I’d say if you run warm and tend to turn your back to your pressure gauges run PRVs on any column that is isolated. If you run cold you could say fuck the PRV’s if you pay close attention to your process but still make sure you have a valve to atmosphere or a line outside of your shop to vent off any pressure built up in any isolated column if it does get too high.
I was told and show a video from Soxs where a nitrogen tank dumped the last 100 or so lbs when it’s the last bit…doesnt always happen and may not ever, but can… Was more safety setting so if something catastrophic like this does happen you don’t lose your rig potentially
Okay few questions. Can I do a nitrogen push with a non stainless regular recovery tank? How much would it cost.to fabricate a 3" lid with the top injection port like they have with the bleed port and injection port?
I have a question. If I’m doing a nitrogen push from the top of the column how do I know when I’ve pushed all the solvent through and it’s nitrogen do I see a cloud of fog? Also when I do the push do I turn off my pump wait for the fog then bleed out of my recovery base? If so how much do I bleed off? Right till the pressure goes to zero?
My recovery base water is set to 36.5. And I’m not sure I understand what you want to know? Are you asking why it’s imporant to know the temperature? If your suggesting that my base is heating up my solvent creating to much pressure to allow the column to drain that’s not the problem I am having. I added a crc and my pump is pretty much pulling a vacuum while my column is at 50psi
In order to vent the nitrogen safely, you have to know that N2 is the ONLY gas present.**
That ONLY happens if your solvent is below its boiling point.
What pressure would you expect from your solvent at body temp?
When does it approach zero (so you can safely vent)?
You want I should spoon feed this? It’s #%^<,ing important.

So I would need to chill it down to -40 to be able to do the n2 push.
if you’re using 100% PROPANE, yes.
Are you?
~0C will work for 100% butane.
doesn’t hurt to go a little lower to give yourself a safety margin.
-0f for 70/30 mix. My issue would be the water in my recovery freezing.
My solvent is chilled to -30c and my column is jacketed with dry ice/ethanol. So my solvent would be good for temperature my issue would I could only push half the needed solvent through before I would need to turn on my water bath or risk freezing. Unless I’m able to do multiple pushes
