Soaps/Acetone

[Jamesrl]

I'm going to try demething before washing as I think this will help with soap removal.

I've demethed both batches before the acid wash phase and the wash water still had a slight whiff of methanol.

For my last batch I returned to demeth bubble and settle but this time I added 15ml of acetone to the 100ltr of bio once it hit approx 20C, continued bubbling for 30mins and settled.

The idea was to see if the soaps settled faster, they seemed to but the result is somewhat subjective.

The general concensus is that most of the soaps will not wash out until most of the meths has been removed,
this is why I want to demeth before washing.

Tony also tried using acetone when settling, but he didn't see any benefit to it.

With Julians recent results I use acetone on this batch but carried on with a couple of washes afterwards,
50/50 tests showed that not all the soap was removed and I ended up doing 5 washes.

I have no soap test results due to getting my samples mixed up (I should have marked them) and having to do an acid wash due to an emulsion.

My next batch will be using ASM, hopefully tomorrow.
