Ethanil

I was reading an article on the kits in one of the classic bike mags, don't know if anyone has used one but it looks easy enough to make something similar in the shed? - Ethanil

Thats my thinking too robotstar, it seems to be a couple of 5l containers and a bit of tube.

P.s. Loads of videos of different ways of removing this rubbish from fuel on youtube.

I worked for sometime on industrial centrifuges, doing all sorts of things and occasionally cleaning fuel. It sounds odd, but water was injected into the fuel as it was being pumped into the centrifuge. This was mainly to dissolve sulphur and other salts. The mix went into the centrifuge, the water and salts were spat out one way, any dirt collected at the side of the bowl was periodically ejected by dropping the bowl bottom and the clean oil went the other way, at a rate of 5,000 litres per hour.

Am I right in thinking you add water to the modern petrol/ethanol blend and it seperates out into an aqueous layer of ethanol and water and an organic petrol layer? So all you need is a big seperatory funnel.

What sort of volume would you be processing?

 

[Robotstar5]

The article gives the fuel/water ratio so you adjust it to suit whatever size container you have

Shouldn't there be an option at the petrol station for ethanol free ?

Shouldn't there be an option at the petrol station for ethanol free ?

The reason there isn't would break the "no politics" forum rule, 'nuff said

The reason its there is as a shift away from crude oil toward carbon neutral (ish) fuel.

I know very little about petrol though. Or petrol stations, for that matter...

I would imagine adding any polar solvent, in volume, will take the ethanol out of petrol.
Ethanol has polar and non-polar regions, which allows it to dissolve in both polar solvents (eg water) and non-polar (eg petrol).

Id assume that, adding water in excess, would allow the bulk of the ethanol to dissolve in the water, which would then be removed.

You could do it continuously, using a mist nozzle, and a "never overflowing" tank.
