Dealing with the new demon of E20

Our Guv in its wisdom has introduced E20 gasoline here in India.
Over several years it has been a hop (E5) skip (E10) and jump
(E20). Soon we will also add a pole vault (E27). Since ages I
had been experimenting with water separation. It does help, but,
it does not remove all the Ethanol and being hygroscopic it ,
the Ethanol keeps building up moisture . Out of sheer
desperation I tried something. I sell SAP gel ( Super Absorbent
Polymer), aka Rain Gel. this gel is used in agriculture and
horticulture to keep moisture localized. In daily life it is
used in baby diapers and a ladies hygiene product for absorbing
moisture. Also a super fine grade known as Hospital grade is
used in Operation theaters and ERs to clean up human mess fast.
I had various grades and the common sodium based gel and the
potassium based gel. Fine dust, medium and granular. Fine dust
is super absorbent, picks up moisture and the medium grade is
transferred some, who passes it on to the granular grade. That
is the theoretical reason for me to mix them before giving it to
my agri and horti based customers, and it works. To cut a long
story short. I added some SAP to a bottle of Gasoline that had
just gone through the water separation process. For comparison I
also had a bottle of the same gasoline without SAP. The results
were extremely promising. And with its ability to absorb
moisture 50 times or more of its volume, the SAP seemed more
like an efficient fly catcher, here the fly being the resultant
moisture from the ethanol's hygroscopic property. Its been only
a few days since the SAP idea hit me and the only available
guinea pig to try my first batch on was my wife's mini hatch.
It has lost all its Ethanol caused issues and runs smoothly. My
two stroke bike get a sock filled with SAP to keep the moisture
under control. I am thinking of small bags of SAP that can be
inserted into fuel cans to keep the moisture isolated. I really
thought this information will find some interest here. Posting a
few pictures below. In the first one I had marked the level of
water , poured in the gasoline and agitated the bottle and then
let it settle. The water line has risen above the mark. Also
notice that this gas is still light in color.

This image is of the gas in two bottles after allowing the big
bottle to rest overnight. Notice the color after the Ethanol was
reduced. The bottle on the left has the SAP at the bottom and
was totally moisture free .

Our gas can have dyes in it or not. Here is Efree 2 different
years.
1 year I had to make sure I didnt buy diesel off road or heating
oil as it was yellow like it.

One idea that seems to work is handling the moisture
accumalation from E fuels that tend to be hygroscopic. Sodium
based water gel aka SAP, Rain Gel Water Gel etc is the trick.
Just ad some into the container, or even tank of the equipment.
It absorbs the moisture. Since it can absorb moisture 40-50 or
even 60 times its volume immedeate replacement not needed. Only
precaution needed is a little bit of care while decanting the
fuel. But since it is heavier than fuel it sinks to the bottom.
In the picture the bottle on the left has SAP added. None in the
one on the right.
