Hi Golan
2 things, 1st read all the JtF site as there are some
contradictions such as BD should be clear after processing then in the washing
section it says the BD maybe cloudy and need to dry/settle for a couple of days
in a sunny place. There is also a good section on emulsions.
2nd do small 1L test batches to sort these sort of problems
out before going big. this includes not only changing the chemical ratios but
drying the oil and checking the accuracy of you measuring
equipment.
I have done quite a few test batches before going to 15 then
30 L batches.
Have fun
Ian

Just joined the biodiesel world and this group as
well.
I’m from Israel & my name is Golan.
Just mixed my first 100-liter batch.
I use
electric pump about 16 liter a minute
& 2.5
kw heater.
I
preformed quality test (150 cc water &150 cc biodiesel shaked toghether in
ahalf aliter jar) after 24 hours and got 4-5 millimeter white layer
In-between the biodiesel and the water.
As
well the biodiesel wasn’t
clear.
I
reheated the tank again to 52 deg C
And mixed it with 10% methanol and 3.5 gram of lye per
liter of oil.
Mixed it for an hour.
Any way I took samples after 20 and 40 min.
I
saw the biodiesel was darker then in the first mix and an extra very thin
layer nylon like appeared on top of the biodiesel .
24
hours later preformed another quality test no spreration at all for aday and
ahalf all ready it stays awaitish fluid.
does any one knows what that layer is and what is there
to do.
All the best
Golan
