Feedstock Oils

I am based in Cape Town, South Africa where the biodiesel market is in its infancy and little is know about biodiesel. 

 

Firstly, In my research of biodiesel processing plants, I have yet to come across a website selling a processor which gives the types of feedstock oils it can and cannot process. ie please can someone advise me on which criteria must apply when selecting a plant to process Jatropha oil, Soy(a) oil, Canola Oil, Sunflower oil, Crude Palm oil, Copra Oil, Used Cooking Oil etc.

 

Secondly, can you point me to a website / manufacturer which produces processing equipment for the harvested feedstock.

 

Thirdly, which is the preferred method of washing biodiesel?
