First off, I’m pretty unfamiliar with the mechanics of cooling with LCO2. I imagine you run LCO2 through a vessel, vent it to atmosphere, and get a cooling effect?
Currently I condense in a DI/denatured slurry, however my DI supply has become unreliable. I was wondering if I’d be able to put a second coil in my slurry, run LCO2 through it to cool the slurry, and keep the rest of my system the same?
Don’t blow yourself up. People have mentioned you need thicker walled steel for lco2
Edit: I see you’re not talking about using jacketed columns, so nevermind
This sounds sketch tho.
I’m thinking a thick walled SS coil, not sure how that’s more sketch than a jacket. Maybe because it can clog easier?
Back to the thickness thing. Definitely do some searching, but I swore I saw standard steel is 3mm and things need to be 5mm thickness for lco2.
But that’s for jacketed steel. Dunno about coils.
Def get as much advice as you can, all I know is from comments here, but guys seem to be extra careful around it.
And get dry ice that’ll expand and stretch thin steel.
I wouldn’t recommend using lco2 for cooling unless the column has been engineered for it
Lco2 venting out of a coil is gonna clog up fast ain’t it?
It’s gonna make dry ice quick then start to expand the steel. Maybe it’s more doable on a smaller circumference like a jacketed coil, but I wouldn’t do that unless it was an exergy coil that has some engineered specs on it.
Yep, so sketch is right lol.
That much pressure scares me.
Thanks for chiming in, I was definitely just going off of what you and dred have commented before on the subject.
Where is LCO2 typically vented to? Collection vessel?
Yeah Boris went through a lot of trial and error in bizzys infancy figuring that stuff out. Or so I heard.
Atmosphere
With a relatively open input, throttle on the output? I feel like a coil in slurry is safer than a jacketed column. If it blows, CO2 goes everywhere–not butane
If it blows?? Are you justifying the safety of an explosion on your rig?
Not justifying, just planning for the worst
Planning for the worst would be not doing something dangerous that could blow up
i can assure you a non volatile explosion is still an explosion you do not want. EVER
Not sure where I gave the impression I want a non volatile explosion. I’m just emphasizing how a coil in slurry design is inherently safer than a jacketed design for this application
sure seems like you are trying to justify the possibility with this comment.
Do ya’ll not plan for ruptured vessels? I have an oversized exhaust specifically for this possibility. My intention for that comment wasn’t to brush it off, just to plan for the possibility of it
