Ethanol mogas

I was wondering if it is possible to remove the ethanol from mogas and
thought of the folling idea.
Alcohol binds with water.
Get a big tank with a spigot at the bottom, fill it with mogas.
Add water, aggitate, let sit.
The alcohol ladden water will settle to the bottom.
Open the spigot, drain the water.
You now have alcohol free mogas.
What am I missing here?

My old flight instructor and salt of the earth, Wally Olson, (owner and
founder of Evergreen Airport) did a similar thing.

Wally kept the bottom third of his fuel farm tanks filled with water. That
way, he said, when there was a leak it was only water.

Would that then make it legal to run mogas with the EAA STC??? Would
the FAA have to approve your separation method?

I think the answers are yes, and what would the FAA care about anyway,
this is MoGas.

If anybody cared, I would think you could make a strong case for this
being nothing more than filtering to remove contaminates.

On the other hand, common sense and regulation are generally mutually
exclusive.

Don't try this on anything above a cheap lawnmower. The octane of the
resulting fuel will be reduced substantially, assuming you could even
get all the water out of solution. Remember that as the fuel is
further chilled, more dissolved water will come out, too. Don't even
think of putting it in an airplane.

The remaning gasoline isn't the same as what you would buy if you got
gasoline without ethanol - gasoline with ethanol is blended taking in
account the fact that ethanol will be added. (octane, distillation curves,
etc.) Then there is the question of additives - would they stay with the
gasoline, or with the ethanol?

I think alcohol is a polar-covalent solvent that tends to hold water in
solution with gasoline. I suspect instead of getting the alchohol out, you
would be suspending water in the fuel that you would not be able to drain.

On the other hand, if you have an engine that can burn alcohol, perhaps some
amount of water in the alcohol could boost the performance of the engine ala
water injection in old military aircraft. You could turn some of that
wasted heat into steam before dumping it out the exhaust.

If the alcohol is being used to help boost the octane, which is a
common tactic by oil companies using alcohol, the mogas with alcohol
removed may no longer meet your engine's octane needs.

Oh, boy the FAA would care. Just to run the mogas you have to have the
STC. Since the STC prohibits using gas with Ethenal they may be
interested in how you got it out.
