It takes a substantial amount of alcohol to remove water from gasoline.

Therefore it takes relatively little water to remove lots of ethanol.

Water and gasoline do not mix.

But if purified water is used to minimize total dissolved solids it leaves virtually no contamination after the water is purged.

Then the so-called de-alcoholed water is passed through a RAcor water separator filter with the "S" series 1 micron filter element.

And Presto, untreated gasoline.

A container with drain valve is needed to purge water from the bottom

Then a one time purchase of a small RAcor filter, and a tiny fuel pump. Put the pump downhill gravity AFTER the RAcor filter.

I haven't a clue what to do with the effluent. Evaporation?

I've got another experiment designed around the same hypothesis; my experiment goes like "drive to the Liberty station that sells 100% gasoline" [emoticon]

As far as uses for the effluent...all I'm saying is that Stolichnaya makes a pretty penny selling water mixed with ethanol...

Most people do not understand the negative effect of ethanol. I can say after replacing almost every piece of yard equipments gas connections, bulb, and tubing that this stuff sucks.
The really bad news is the government is saying they will ease ethanol restrictions so they can add more. This will destroy many 2 cycle tools permanently.
I'm from the government I am here to help you .....not.

MEX:

If you remove the ethanol, remember that it's not only a fuel extender, ethanol is also an octane enhancer, and, a pretty good one at that. So, if you are starting with E15 and say, 87 octane regular fuel, you will end up with +-15% less lower octane E0 fuel which may not work well if your engine really needs 87 octane fuel.

Adding ethanol allows the refiners to produce cheaper (lower octane) gasoline, then increase the octane rating at a remote blending facility before it gets sent to the retail outlet.

Dozens of videos on YouTube showing how it is done. Here is one.

How to easily remove ethanol out of gasoline.

Fortunately, in the US, there's not a lot of water in gasoline. And alcohol doesn't remove any of it, but combines with it so it's not an issue in engines. But I'm led to believe you shouldn't drink the water in Mexico.

"Purified" implies nothing about TDS. Distilled or deionized water is free from minerals so can dissolve them.

Uh, what? Alcohol and water are miscible. A "filter", especially one which is based on particulate size ("one micron"), or which which separates based on specific gravity ("RAcor", sic) won't do a thing. Perhaps you should get a De-alcohol-orizer.

I used to mix my alcohol and water with a little soda and a twist of lime.

The 1 micron filter is to filter out inevitable debris of which my living down here makes me acutely aware of. When my day tank was built (100 liters) the RAcor caught an unbelievable amount of detritus. I would expect no less from a home brew separator tank.

I should have pointed out in the beginning I guess that mass separation of lots of gasohol would be impractical. This is aimed at low volumes, like mowers chain saws and outboard motors.

My say tank has a pyramid shaped bottom with drain valve at the apex of the pyramid. A stainless steel 1/4" Globe Valve. The pickup is on the base of the pyramid (remember everything is inverted) I fill the day tank after use, during the non use intervals not only does the water go to the bottom, so does the settled debris like imported rust and dirt.

Nest is a 30 micron spin on Detroit Diesel filter then comes the RAcor. I have to change the Detroit filter every six months, and the pricey S filter once every 2 years or so (mostly for drill). Because the Kubota was upgraded to use a micro Isuzu turbocharger, it meant lots of parts had to be changed, The fuel injection pump was hand built by a wizard in Long Beach. Not something I want to gamble with.

Jesus has a smaller RAcor used when transferring fuel from drum to 40 liter translucent white lancha tank, I really need to get a second filter for him. Plus a used 60 hp Yamaha engine.

Get a water separating fuel filter and move on. Marine stores will have them.

Trying to play chemistry is likely to cause more problems than it solves.
