Hi Des, This is my idea for a recovery still, *keep in mind I have not actually used it yet so it may not work but it might give you some ideas.* I got some SS tubing 1/4" and bent it in a zig zag for about 2', took 4" PVC and put a 1/4 hole in each end and a 3/4 NPT top and bottom on the side.

Hello Bobby, Copper coils are used for oxidation of methanol to formaldehyyde which itself will oxidise further. if you are selecting stainless steel ignore initial higher as it is the appropriate material to use and it will be more economical long term.

Kurt, I've read that copper causes biodiesel to oxidize so the copper tubing is probably out. The reason I looked this up is because i have considered using a 50 gallon water heater as my processor, but the cheaper models have copper heating elements. The higher end ones have stainless steel he

I am getting ready to build my first processor. It appears that everyone uses black to plumb everything. I have read that galvanized can be used but is not good. How about copper tubing? Will it stand up to the chemicals used to process bio-diesel? Mark McElvy AccuBak Data Systems, Inc. 573.435
