The % purity of ethanol has to do with the cost of purification. A standard industrial fractional distillation tower can produce 95% ethanol in one pass.
Yes
That's it. Anything above that needs a second or third pass,
No.Cannot be done, the 95% alcohol:5% water mixture boils at a lower temperature than pure ethanol and will always remain 95%:5% at each distillation. To make anhydrous alcohol needs a separate process like passing it through oven dried cracked wheat. Search on positive azeotropic mixture
Very few ethanol stoves have low CO,
I believe you, all I was pointing out is that if it is producing CO it is also likely producing aldehyde
