Re: Fat fail
Hi Johnnojack,
This sure brings back found memories. These are the type of problems that we often talked about 15 years ago when just about everyone used NaOH.
Now that just about everyone uses KOH instead of NaOH, there is virtually no "glop" produced. You either have separation or you don't.
That is because KOH makes liquid soap, not solid soap.
Even the latest nonsensical "foolproof" procedure that uses 20g KOH per litre of WVO! does not produce glop, it just produces lots of liquid soap that ends up in the glycerine layer.
How much of of the sample that you washed do you think is biodiesel?
Two things I would do
1. I would wash a sample of the glop from the reactor the way you washed the last sample and see what it looked like
2. I would do another reprocess cutting the NaOH back to around 3.5g per litre of WVO
