Hi Bob, Joe, Thanks for clearing up the Nitrogen reactivity for me as well, I had read about the nitric acid and just figured that there may exist some ugly possibilities. I am no chemist either. I am confused about what vacuum enhanced sparging is ? Do you just let the vacuum suck down then

Hello Keith, I just like to see something that has the possibilities of taking focus away from the hydrogen myth and all the coal that goes with it. I suppose that is highly optimistic but then who can say how it will all go in 10 years?. Jim Keith Addison wrote: >>This is just about as coo

vacuum under any conditions should not impact the biodiesel, nitrogen gas shouldn't impact, even nitrogen, vacuum and heat wouldn't be a problem. If you want to impress the folks at the next potluck, tell them you're using vacuum enhanced sparging. ;-> My comment on forcing conditions was ju

Thanks Jim; I'm not a chemist so maybe you can fill me in on the reaction.  Air is about 80% nitrogen so is the degradation that people have been referring to as "oxidation"  just a generalized term that includes a nitrification process as well? Joe PS Helium is expensive!  And so is Argon.

I assume that this only replaces the transesterification step, and you would still have to wash to remove glycerin afterwards. Seems like this would almost be a better technology for the very large plants, because it turns a batch process into a contiuous process which is what they have been hampe

Thomas, That's 0.20 ml per liter of fuel to be washed. Adjust as needed to bring the wash water to neutral, which means toy with it. Doing this in the first wash will yield remarkable improvements in any subsequent wash. Todd Swearingen Thomas Kelly wrote: >Todd, > I've been sold on stir
