I could start a new topic, or ask in @TheGratefulPhil’s thread, but think this falls fairly close.
I just asked the manufacturer on my 100gal vac assist still what his guess was for recovery time for 100gal of 190proof ethanol under vac. He said “an hr or two”!!
I’m having a really hard time with that number, but don’t really know where to start to come up with a better guestimate.
100gal EtOH. vac at -26" Hg or so, to give a boil temp of 35C. Driving with 60C hot water in jacketed vessel. Running coolant through the condenser at -25C if I can manage it.
What other information do I need (condenser area?)?
even pointers to the correct maths would be helpful
Edit: seems like heat input is a required parameter. still haven’t found the maths. I’ve been advised to throw 150kBtu worth of water heater at the problem.
Edit: made a new thread and took a stab at the math. looks like the manufacturer might be on target.
