How about shall we not say "nefarious purposes." The salt will precipitate during the FFA recovery.
And glycerol is not going to be worth anything more as a fuel source than is sugar. It's an alcohol that's as thick and as sweet as honey in it's pure state. If you've seen sugar burn then you're already familiar with what glycerol would burn like. You'd have better luck getting the glycerol cocktail to burn, as it has a higher energy value due to the methanol and FFAs in the soap. As for producing NaCl from any process? The intent should be to steer processes away from creating waste products, not creating more. The wash process doesn't need to be a brine to work. The caustic should be potassium whenever possible and the waste salt from FFA recovery should be something that has and end use, such as potassium phosphate, making the process an almoste entirely closed loop. Glycerol disposal (that's after methanol, caustic and useable FFAs are recovered) can either be by sale or simply dissolved in the treated wash water and dispersed as gray water irrigation. Again, the purpose should be to reduce the waste stream, not add to it.
