I plan on doing ffe with ethanol.

Would this be ideal for a steam generator? or can I just use a tankless water heater and pump water into the hot dephlegmator? I see steam is generally used for FFE that’s why I asked.
bumping for answer
use hot water or hot oil

Do those work with BHO?
Theoretically yes, I wouldn’t personally do that. There are better ways to skin that cat.

So for chilling I can’t decipher if glycol lowers the temperature of already freezing water or if you have to mix it in with the water and then apply cold to it.
Everything I’ve read said glycol and water can get to - 40 to - 60 effectivly. I just can’t tell if it means already freezing cold water then add dry ice. Or make a dual or triple resivour.
I know regular glycol chillers are a thing I’m just cheap and bored.
…before they FREEZE.
No, adding glycol doesn’t magically make things cold.
(Neither does adding salt to your ice. )
I’ve got a couple of other words I’d use…

I was terribly worried I was going to hear he thought glycol just… made cold
But rereading this, I definitely see that’s what he was asking.
Christ. That’s not groovy at all.

“I can’t decipher if glycol lowers the temperature of already freezing water or if you have to mix it in with the water and then apply cold to it.”
I’m not thinking that glycol “makes things cold” I was just thinking if you added it to already freezing cold water and then apply more cold to it, could you possibly get to - 40.
Like by just having the bucket with the glycol water mix in a igloo cooler with dry ice… Something like that.
I’m not an idiot. I’m just wondering if it would be more ideal to mix it in first or if it’s more ideal to gradually keep adding. 
I guess I should’ve worded it like that.
It does Infact lower the freezing point. There’s a handy chart around somewhere telling you the difference freezing point to glycol proportion of Ethyl/propyl glycols

Order of operations is irrelevant unless you’re trying to circulate while cooling and adding stuff.
Own a car? Do you mix in the antifreeze after getting your car cold? Why do they sell it premixed?
It will start to slush around -40.
It will be solid before it hits the sublimation point of dry ice.
Can you modulate your dry ice additions to maintain -40? Maybe.
Certainly not on my list of to do’s….
Try it and report back, or go find the previous report.
