There's a very simple way to deal with ethanol and I'm not being facetious.  Every single EAA / AOPA / rotary group member should run for some kind of office in 2012.

Years ago, when this govt funded boondoggle first started, I looked into building a still, er, ethanol processing plant.  In order to avoid paying taxes, the white lightening, er, ethanol, had to be immediately denatured.  The process of denaturing made the white lightening, er ethanol, unfit for drinking.  This was done by pouring gasoline in it.  The idea was that you could not remove the gasoline after it was introduced.

 

If this was good enough for the Revenuers, I suspect that it would not be possible to remove the alcohol from the gas as well.

Well, if you don't blow yourself up in the process, you will now have low octane gas for about $4.50/gallon.  Then you'll need a method to transport it to the airport, then pump/pour it into your fuel tanks, again without blowing yourself up.  From a risk-analysis perspective, it doesn't wash (pun intended).  I just don't see the benefit here.  It would almost be easier to fly to Oklahoma whenever I needed fuel for the airplane.

Charlie is right, you can extract the ethanol with water. Best practice would be multiple small washings to reduce it to a negligible level, but octane would suffer. Also, your price of auto fuel just went up, because you are sending some down the drain.

Basically there is a partition coefficient for alcohol between gasoline and water.  Each time you add water, x% moves to the water.

Thanks, Bill.  That chemistry class in college was a LONG time ago for me.

So, how long will it be before someone starts selling a system that allows you to put contaminated gasoline in one end, have it add water and then centrifugally separate it, let the clean gasoline go out the other end, and distill the water to reuse it?  The ethanol would drive the distillation, and the left-over could be mailed to the stupid politicians and lobbiest that keep adulterating our gasoline.  ("Here!  You like it so much, you can have it!")
