Kenneth, I can see a problem here if the process was single base and the feedstock was high in FFA. The addition of acid could convert the soap formed from the initial neutralisation back into FFA. Careful monitoring of the ammount of acid added might prevent this. Whilst FFA is a good fuel in itself its compatability with the components of a diesel engine is highly suspect. >In fact if you follow the "Fool proof method" then you do almost exactly >this.

Another way to strip some of the methanol from the raw biodiesel would be to use glycerine from which the methanol had already been distilled.. Mix the raw biodiesel and the glycerine. The methanol will disperse 50/50 in the biodiesel and the glycerine. The methanol can be distilled from the glycerine. But would it be cost effective?
