A winter's worth of BD tailends & gloop. What to do?
« on: April 09, 2014, 07:01:56 PM »
Last year I decided I didn't want to make any BD over the cold winter months so stockpiled enough to get me to Spring.

The BD was made & then sat, some for 6 months, being decanted by gravity pouring into a clean jerry can before being put into the car. I stopped pouring at the first sign of any whites or anything that didn't look like clear BD.

I now have about 60-70 litres of this stuff. At the bottom it's pretty thick gloop, at the top it's kind of slightly cloudy BD with a waxy scum on top. Not quite sure what it is exactly, all the BD I made had a 100% pass & sailed through every test - 10/90, 50/50 & dryness. It remained clear & uncloudy all winter & I used it neat all winter with no winteriser or petrol added.

What to do with it?

I've thrown it all into the processor thinking I'll add about the same amount of really clear, clean feedstock & use it in the next batch, which I'm thinking should be a 1 stage process (hopefully).

Does that seem sensible to the panel or is it a waste of time to re-treat it & I should dispose of it?

Chuck it in with the glycerol wash.

You will find that most of it will stay in the feedstock when you drain the glycerol.

Do a 90/10 before you dose the chem, as it would then be very possible to overdose.

Then 2stage etc. as you would otherwise.

Yeah, that's pretty much what I planned to do with it.

Should be interesting to see what the end result is.

Should work. Just make sure you 10/90 to get the dosing right and two stage for complete conversion.
