I use my injection coils for recovery as well. You could easily do this for your set up too

Got it, going to go to dual 3/8 vapor lines, 3/8 liquid lines and eliminate bottom fill.
I have an instant hot water heater in my shop that Iām not using so Iām going to start brainstorming on how I want to set that up.
@FicklePickle
And that makes total sense! I dig it. Thank you.
I will post an adjusted diagram tomorrow.
Thanks again guys!

Get a stainless tank that has multiple vapor ports (2) Ā½ vapor recovery. And (1) ā for nitrogen/vac.
Dunk the tank in a dry ice slurry and ditch the coils.

Did you see the video at the meet up of the bolt giving out on a cls at 120 psi? @Dred_pirate wasnt that video gnarly? That rig took off like a rocket ship

Do you have a link to the video?
I ordered a 50lb stainless tank. 2x 1/2ā vapor ports and 1x 1/4ā vapor port.

Based on your guysās Input I will he making the following adjustments:
Delete bottom fill
Solvent tank will be in slurry
Single coil in slurry plumbed for injection and recovery.
Going to return 1/4ā lines and use 3/8ā lines all around
Ordered some extra 10ā gaskets with the outer lip.
Still chewing on instant hot water heater set up. Got a couple ideas but noting concrete yet.
I will post an updated diagram tomorrow.
Thanks again

Thatās interesting Iāve always found the opposite. Acetone seems to boil less aggressively when chilling as well as consuming less dry ice by a factor of half in my experience. What proof was your iso and what percentage was your acetone? Pellets or chunk for dry ice? Iāve seen both hang at roughly -70C regardless of solvent. Is your experience different?

My understanding of this is that the stable low temp will be very close regardless of solvent (acetone or 99.7 iso) however the acetone slurry will have less temp fluctuation due to the heat transfer.
I am going to mess around with both slurries using dry ice pellets and will let you know what my experiences are.
This is from my brother who is a biochemist:

Acetone is in my opinion far more aggressive then iso. The reaction alone when introducing the two is vastly different, bubbles and speed at which the ice lasts. Iām talking about everything directly out of there containers, brand new.
Home Depot acetone
99.7 iso
Type of dry ice hasnāt matteredā¦ surface area on the pellets is far higher so it goes through that faster. That can be controlled by feeding it with dry ice slowly over the entire day.
They donāt use isopropyl alcohol in this video, but I feel itās very close to etho alcohol and itās reaction with dry ice.

Acetone transfers heat better therefore it would transfer the outside heat to the dry ice faster in this experiment since theres no insulation resulting in a more violent boil.
Try getting a vacuum jacketed container to hold your slurry and the outside heat wont kill your dry ice as fast
This is true in any solvent
I use to use a yeti for my coils with a lid, that shit worked great and made my dry ice last way longer
Unfortunately it eventually broke

Iām not disagreeing with you at all here. I just think acetone is best used if your process is very quick. Otherwise, your ice and acetone are just sitting sublimating at light speed. Once I upgrade my collection vessel and donāt have to throttle it, Iām sure acetone will make a huge difference.
Iām using Home Depot job site coolers right now.

For my heat exchanging system. I got a couple bulkheads, then NPT to quick connect water hose adapters to return the cold water into the heating bucket using a 3/4 garden hose.

Is this what yall arguing about? When choosing different solvents a chilling solution?

Sieve beads? The sieves are between the collection pot and the solvent tank. One for each recovery line

Also decided to go with dual 1/2ā recovery lines instead of 3/8ā
Parts started showing up this afternoon. Woooo. Stoked.
