-A brief introduction to SVO

Small Scale processings

Notes to writers:

I think the idea with this chapter is to give an overview of all the different parts of small scale processing. Each section could instill a general understanding of the importance of each facet within biodiesel processing and give ideas and traditional methods. For instance, the mixing tank section could say that a mixing tank needs to be big enough for your oil, catalyst, and some head room for pressure/mixing space. It could talk about the desirability of good drainage and conical bottoms, mentioning common tank designs (appleseed, 55 gallon drums, drums with welded conical bottoms, and purchased HDPE tanks). The titration section would explain the importance of titration, necessary materials, and a how to, etc etc. This chapter is a synthesis of theory and how to which will be woven together in our making a batch section and our processor designs section.

Small Scale Processing: TOC

-introduction

-heating devices

*The need to preheat (dewatering, optimal reaction heating)

*Hot water heater elements, burners and wood fires,

*toward a drying strategy.

Making a batch in our processor

Notes to writers: This chapter is outlined at the process from start to finish of making biodiesel. It will most likely be a very short chapter written by WDA members about a typical routine batch in our processor, from start to finish. If Centrobiodiesel or other individuals would like to write a short essay about their biodiesel making routine, it would be great and we could include it on the wiki. This will intertwine all the knowledge in the theory section with a processor design and give a whole picture.

Making a batch in our processor TOC

-introduction

-*preheating

-calculating and adding methoxide

-mixing

-prewash

-settling

-draining glycerol

-washing

-filtering

Oil

Notes to writers: This chapter should give a brief introduction to oil. It should layout our research on Jatropha, Palm, Castor, Lard and include a good chapter on WVO acquisition. Each oil section should talk about information on the oil, a brief sketch on its pros and cons for growing (including a guide to sustainability), and things to take into account when processing with it. It should also give reference to further resources (publications and people) who we know are working with sustainable oil production and processing with it.
