*********************
Topics covered in Advanced Topics class:


working with high-free-fatty-acid oil

working with high-water feedstocks

acidulating glycerine and wash water for easier disposal and cost savings

testing biodiesel, glycerine, and wash water for soap

producing biodiesel from oils recovered from glycerine

acid-catalyzed esterification options

methanol recovery from biodiesel (GL-1 process) and glycerine.

using glycerine as a solvent in various stages of the process

There will be an extensive hands-on section of the class devoted to
techniques for making biodiesel using ethanol instead of methanol, and we
will discuss small-scale fuel ethanol production.

We will also discuss water-free soap removal such as the use of the GL-1
process and ion exchange resins.

Introduction class: there is a hands-on, introductory class for those with
no prior experience, on the Friday before the Advanced Class.
