In the Real World…In the Real World…Not all feedstocks are created equal, and
often times the cheapest and easiest to acquire are, in many ways, the hardest to work with.
Feedstocks that are higher in Free Fatty Acids (i.e. used fryer oil), known as FFAs, require a titration that determines how much extra lye is needed to compensate for the oil’s acidity.
Feedstocks that are really high in FFAs may require alternatives to lye, alternative amounts of alcohol, and different production processes entirely.

The reaction is done around 130 deg F, at overnight settling. The reaction is done around 130 deg F, at atmospheric pressure, in a stainless steel reaction vessel. A simple atmospheric pressure, in a stainless steel reaction vessel.
