I’m currently running a1lb closed loop system With a dewax column And am struggling to get temperatures lower on my collection chamber. I place dry ice in the dewax column as well as around my shatter platter. But my process is taking far too long (2+hours). Anything that I should change up, should I use regular ice on the column and dry ice on the bottom. Or something that is easily accessible to add to the dry ice to make that a little colder to have a lower temp for the butane to continue to chase the colder temperature?
You are talking about your recovery vessel when you say collection chamber? Most people in the industry use collection chamber as a term for where the oil is collected after the gas has been recovered into the recovery vessel. If you’ve got a valve between the material column and the collection chamber, close it when you start recovering so the butane isn’t trying to go in two directions at once.
There are a few options , isopropyl comes to mind,
more detailed description of your process and temps will be beneficial in a resolve
N2 asist also comes to mind
When you say two hours, is it total time, extraction, recovery?
We definitely need a lot more details before anybody can make any kind of suggestions.
Seems like a couple or four 1k word substitutes would help folks figure this out.
Yes recovery vessel = collection chamber. Sorry for term mixup. And I don’t chill my butane before hand. I will start doing that. I do have a Ball valve but I’m referring more to the extraction process not recovery so that would prevent the butane from traveling completely through the system.
2 hours for extraction
I will do another run and not those temps down for your input. Thank you
Put your whole collection chamber on dry ice not just platter.
2 hours? From when you open your solvent valve till you crack open your collection? For a one pound system. Your doing fine. Shit you could make four or five runs a day like that.
No thats too long. Should take an hour to an hour and 20 for the entire run
very similar to my collection, i slurry it and then over the hemi lid with pellet, ive noticed marked improvement with the extra pellet iver the lid
i agree, 2 hrs is decent, you can probably get stonger flow with the right temps
soak or no soak? separate column dewax? op did not state, if its a wash through , around an hour would be good imo
I think 2 hours to get solvent from solvent tank into collection is what’s happening with him.
I don’t even chill my collection anymore. I chill the incoming gas to -80c and push with n2 at 20-30psi. The collection starts to chill itself with the -80 gas asap. And I do 3-4lbs runs in about 3hrs
That’s the ticket for us smaller guys. Chilling the solvent tank to -80. Push with nitro into a warm collection, recover straight back into the chilled solvent tank.
It’s very efficient and I can run a higher throughput. Your not taking a vessel and warming it, then cooling it, then warming it etc. Your vessel is already in the range of desired temp the moment you need it…no waiting to make a 150 degree temperature swing.
But I’m a redneck with questionable morals…so don’t necessarily isten to me
I just started using a injection coils for injection and recovery. What a difference that made
No joke, my coil is my bff now haha. One of the best tips I picked up here was adding a coil into my setup.
