Ken, I have been experimenting with using water and various "catalysts" to clarify WVO. My aim had been to "drop" the particulate matter from WVO as well as neutralize any acidity. This would lengthen the time between cleaning WVO processing filters as well as preclude any injector/pump damage from long term use of acidic SVO/WVO.
Forgive me if I am asking stupid questions. When you refer to the dilute NaOH solution "and lots of it" are you referring to and NaOH and alcohol (ethanol?) solution? If you are do you recover the alcohol and reuse or does it go into solution in the WVO? Do you think that this might hold promise for refining WVO to use as SVO?
