Thank you! This is the best setup I’ve seen. I like your methods.

That's by far the best way I have seen for separation on KZfaq. So thanks for that. I would also do this outside. And thanks for the links, although the 2000ml separator is expensive in the UK. I'll be giving it a go as suffering from expansion of the fuel tank on my Triumph Speed Triple.

Although I doubt most additives are very water soluble, you may be removing some inadvertently. Would be interesting to know exactly what is added.

What can be done with the ethanol/water mix? Can it be distilled to separate thenburn the ethanol to warm you home or cook on?

So add 10% water to the jug. Dump in gasoline,. Shake a few times over the next few hours. And wait over night and pour the gas off leaving the water behind. Cool.

what do you do with the ethanol/water mix that's left? the ethanol is used to raise the octane in gas so you removed it which lowers the "grade" of fuel so what are you using to bring the octane back up.

This is only worth it if you can't buy ethanol free gas. Where i live its maybe 30 cents per gallon more and this equipment currently costs over $143. I would have to process almost 500 gallons once I deduct the ethanol removed to make this worth it. Fun experiment to do to test the gas in my area, though.

Thanks god bless

You shouldn't discard ethanol, you should distill it out of the water and keep it for other uses Table top water distiller does a great job

Sorry, nice try but surely all too fast with far too much movement of the can causing small quantities of water and ethylene to remain in the gasoline, and better with a dye in the water. The glass container used is perfect for filling with the gas and water, bigger would be even better, and leaving for hours if not over nite, then opening the tap to drain the ethanol/water crap out, leaving just gas that can be emptied directly into a gas container ?

Sooo you aren't adding dye to the water to help identify alcohol/water mixture, and instead of letting mix separate in funnel you pour it out as 'gas' into can. You should let it sit, separate in funnel, pour out bottom alcohol/water mixture, then what remains is gasoline. Also you should start with highest octane gas you can get as the rating accounts for combustibility of the ethanol you remove. Start with Super in other words.

Can someone please do a before and after at the lab !!!!

How do U bring up the octane rating if your using 87 octane. And how Much octane booster do u Add for a gallon

This gave me an idea Sir. Would just filling a gallon with salt at the bottom do the same thing and just discard the jug with inpureaties for the trash man ????

Better idea and a hell of a lot cheaper if you just need maybe one or two liter for your leaf blower, just get a empty 32 oz. Clear bottle, fill with about 3.5-4 oz. Of water, rest gas, screw on top and shake. Wait an hour or over night, and than sniffing off the ethanol free gas. You prolly already have the bottle in your fridge, buy a sniffing hose and your good to go. No need for ~$120 bucks of glass.

I've recently wondered again how much cotton, a real chamois or maybe even just oven dried desiccant like say commonly found CaCl or silica gel would perform quantitatively?

Couldn't you mix it in a water jug with a valve at the bottom then drain off the alcohol/water?

Good for weedeaters

where do you dispose of the ethanol/water mix. Is it hazardous?

After you shake it, how long does it take the ethanol/water to sink to the bottem of the red gas jug before you pour it?

yeah - wtf wxf? do tell! Actually there are a dozen other ways this particular setup is overkill - but put it on a table and the container on a bench so you don't have to transfer it using an intermediary. If you pour that e10 etc into proper container like a 5-gallon water bottle from a water cooler (very thick) - and drain the water then pure petrol out a valve you install at the bottom you would be in business a lot faster - cheaper too! If you want to filter the last 0.1% of water from the gas you would have to run it through a paper-stack. They actually use rolls of toilet paper with no side-effects for that among other things. Just find a suitable PVC pipe and caps and you can DIY. You need a small fuel pump and the hose can go in and out the top - just let it run a few minutes. 1 roll will hold about a quart of water and the TP will show cracks and separations when it needs changing.

Take it from a chemical engineer; This isn't how you properly use a separation flash (or funnel) at all.

Maybe you could buy a gallon of ethanol-free gas. You might be spending fifty cents, but you'd save 30 minutes. Your process did look fun though.

can you use tap water instead distilled?

Old PT shirt I wore mine yesterday to sand my fence.

Using water, the mixture would have to set overnight to alow the water/alcohol portion to settle at the bottom. Using a clear juice bottle would alow one to just pour off the gasoline, leaving a small amount of gasoline on top of the water. Which is exactly what was actually done in the video! Capping off the residual water/alcohol/gasoline to reuse for the next batch without losing any gasoline. Or it could be siphoned... kzfaq.info/get/bejne/qqeRhtByp8WqcXU.htmlsi=OjlW_-J1-EsQAzSG

Nice effort but I’m not gonna break out my chemistry set every effing time I need gas.
