Is there any advantage to pushing with N2 over having a second solvent tank, that is at ambient temp, to pressurize the the cryo solvent out of the primary tank and into the column?
Yea, when you run cryo, you can’t push with solvent because the solvent will phase change into liquid. And eventually it will warm up to gas but then you just got your run dirty with warm solvent. I push my butane with propane but only when I extract warm.
I want to push for the same reason, I don’t dewax or winterize and want the highest quality meds I can get. Cold solvent seems to do the trick for what I’m after. I can probably get into nitrogen cheaper than a second solvent tank…I’ve got oxygen and argon regulators on hand. that choice was easy lol
I removed this thing from the spot the prv is at…the part I removed kept leaking… So I thought the prv would go nicely there
Only issue, I go to open my tank and my prv goes crazy… I’m thinking it needs to be on the other side… Only thing I have other than prv , is a plug and the original part that come in the spot the prv is at… Please help this is my first n2 vapor bump
Prv 150psi…but I think it should be on a t w the jic ,no? Like to the regulator gauge side, not tank gauge side …And maybe a plug where I have the prv, my regulator was used, and come w what I took pictures, I’ll get another pic of the piece I took off this spot aoon
Bc does the first gauge take what the entire tank psi is? Bc if so then this spot somehow is bypassing the next gauge, where u dial it up or down
This is what came in the spot I put the 150prv, I use the same ones on extractor, tested they work at 150, tested the one I installed too!
prv should be on top of your “cold zone” where n2 ends up, or on any tanks you’d prefer didn’t explode (collection pot, material columns, solvent tanks, filter stack)
first gauge after valve is tank pressure, second is flow
Exactly, the PRV needs to go on whatever you are trying to keep under 150psi(after your gauge). I’m not sure what they fill those small tanks to for nitro.
Why is there a port on the tank side of regulator, it had some weird hook up port , that’s what I’m holding in the pic, after I removed it… If you look at picture under it, that thing was located on the tank side, where the x I made is, where I messed up and put prv… I’m guessing I need my plug that I already have by chance there?
I’m getting better pics soon, my hands covered been running since last night …
Have a hash phone
Go back to original pic w m&Ms pack…u can see how it came, w that port weird thing next to tank hook up… There’s another 1/4" opening on the flow side also, was empty I put jic, guessing needs t w prv and jic, or maybe no prv even there at all, they all over my extractor
Nitrogen vapor assist allows for a controlled pressure feed that you can manually increase and adjust. Compared to a random pressure you are getting from the warm butane, which needs to be constantly warmed to produce more vapor pressure.
While pushing with warm butane/propane it will also increase the temp of the cold liquid solvent you are extracting with. So its not as consistent and homogenous.
The down fall is that the nitrogen vapor has to purged out of the system, ideally a cold vessel, before solvent recovery
