Yeah fractional distillation would be the best way to reuse the alcohol but this is something I'd rather avoid. Our production staff are not the most careful people around and I don't mean to say they aren't smart but they have managed to do some pretty stupid things. The last thing I want is to add is highly flammable vapor into their routine, I'd much rather keep things simple and safe if possible. Also have to consider the cost of distilling, the energy required for the process is significant in comparison to the cost of the alcohol.
I don't want to heat up the alcohol in the washer either, this would not exactly be safe. I actually have a thermo switch installed which shuts the system down if the fluid gets too warm.
