I meant to add that your beer head picture looks exactly like mine did when the bubbler was too low, that was before I ever added Acetone to anything other than my fuel tank.

I'll keep that in mind and lift it next batch but I think you said yours was soap? I am sure this is HMPE but it could be lifted from the bottom in the air like the soap. The soap in the bottom of my tank is almost always a solid which I have to dig out.

Same here with my bubbling for a long time (also a low bubbler - never even thought that height would affect it - next batch it'll be higher to see what happens).

Sorry that was an assumption of mine, I think I scooped it out and it ended up being discarded without any testing at all.

I usually keep my bubbler quite a distance from the bottom of the drum. It's surprising how much of a circulation it can set up.

Similar theory to an air lift pump I think, although I suspect liquid density may come into play in the diagram ...

My bubblier was always in the very bottom, I'd have to pull it out of the settled soap/gly each time I did a new batch,
and then let it rest on top.
I've only ever seen honeycomb looking stuff form on top, and this was if I'd made a really soapy batch.

My bubbler is also resting on the last batches drop out and I never get a head like that in the picture. I did in the very early days of bio brewing but not for years now.

Jim, what did you put the head down to? I have never had one till this batch with the acetone.

Wet feedstock and/or excess of catalyst are the main suspects.

I'm getting some Acetone soon and will be playing with a few of my own ideas namely ASM and AAF reaction and distillation via the RED.

Dickjotec · « **Reply #144 on:** January 28, 2013, 08:27:40 PM »

Oil was as dry or drier than normal and it was the least catalyst I have ever used for a full reaction so that rules those two out. Btw what is RED?

Ah, that's the new name for a Squirrel, a Rapid Evaporation Devise or Red Squirrel

Dickjotec · « **Reply #146 on:** January 28, 2013, 09:06:48 PM »

Is it the same as the 'old' squirrel or a new device or just another new acronym?
I shall be interested to read your experiments with acetone, it seems like a big step forwards, too good to be true! Perhaps like all TGTBT it is not true?

Hi all
Tomorrow I'm going to some test on the Glyc produced from acrtone reaction I'm wondering if the soaps and catylist remain more so in the bio than in the Glyc.
Maybe this is why we're seeing less Glyc
If this is so then it could cause some problems with de mething alone

That would explain the seemly higher yield, and Dick's foamy top.

Yes the is some strange stuff going on.

With my micro batch 13% meth/Glyc. 75% catylist
Heavy layer of soap between Glyc / bio
Crust over the top of bio that I believe to be hmpe

My first batch 20% meth/Glyc
Decanted from Glyc
Heavy formation of soap through the whole sample

Steve also has a anomalies that we're going to look at today.
IMHO I think that we should probably hold back on full batches for a few days till we get the cleanup sorted.
