Re: Emulsion and fuel testing

SOme more suggestions from the peanut gallery:

If you succeeded in separating the emulsion by adding acid, titrate the
resulting esters (exactly like you would titrate oil)- they're likely to
be really acidic. I wouldn't put the fuel into a vehicle without some
sort of further processing if that's the case. Normally, washed
biodiesel titrates at .2 or so if using NaOH solution to titrate.

If you separated it by adding glycerine, then make sure you wash it
again, it'll still be both soapy and wet.
