Yes I chill my solvent tank first, then once I’m ready I use nitro to push through…I noticed my recovery tank will pull the nitro because I wont see any recovery happening even though its empty and on dry ice…as soon as i open my vapor line on the recovery tank it burps out a good amount of pressure and that’s how I know it’s the nitro because my tank was empty and cold so there is no reason why it should hold pressure. Also as soon as I do that recovery begins and the aggressive sound of the vapors coming in confirm the nitro is out and recovery has began. The burp is only about 5 to 15sec long

Ohhh ok you’re running passive. It seems running nitro assist is more difficult to vent with active recovery

I have my whole collection on quick connects so I might just run a diy chiller and hook up the chiller to my collection, drop the temps, vent nitro, then plug in my heater quick connects and start recovery. That should work right?

Yea as long as your butane is cold enough it should be only nitro being burped

I think I’m gonna set this up today. Just had one last question. Do I have to worry about any sort of thermal shock on my jackets going from 90°f then Having a dry ice slurry run through it a few moments later…

That’s a good question I noticed my open jacket “move” on one of my tubes when adding hot water to recover the gas in the column…that tube was my first tube ever it’s old and it lost its supports on the top part of the jacket so I’m guessing that’s why it moves and the others dont but it did let me visualize the thermal shock…maybe one of the other guys can answer this

This is how I do it. Works great. Constant ability to switch from cold to hot on the fly.

Do you use quick connects? I’m a little worried the qc’s won’t be able to handle a dry ice slurry

Nope. I actually just swap my pump over from hot to cold and so fourth.

Well I got it to work super well. Injection was insanely quick at the lowest temps I can get. But after injection there’s still all that solvent left in the column. How do you get the rest through?(sorry for the dumb question) With my active system I use the vapor pressure from the pumps to heat up and push the rest of the solvent down into the collection.
This is how I used to do n2 assist: I’d flood normal at like 15psi then shut it off and push through with nitro to clear the column if vapor assist didn’t get high enough psi to make it through all the crc media.

I hook up recovery to the top of my column, remove the dry ice and add hot water to the jacket to push the remainder of the solvent into recovery.

How would I do this with distillate? which is presently 94.8% delta 9 as i dont want end up with bunch delta 8 just to have clear oil.
Dissolve, filter, recover solvent.
What, wait? Who the fuck are you? I know who you are man!

Can someone expand on the nitro push? Do I add my solvent then push with nitro?

No, with valves closed and prior to injection,
Charge your cooold solvent tank with desired psi using an inert gas,
Then it’s happy injecting🤙

You definitely don’t want to thermally shock your stainless gear with a delta-T of 160 degrees. Won’t do anything noticeable to the eye the first or even the tenth time but beyond that you’re playing with fire.
