... recovery, ... We have started one with a 200 gallon propane tank and will use vacuum to bring off the methanol at a very low temp-"105" degress under...
I recover methanol from the glycerol byproduct and so do several other members of the St. Louis Biofuels Club. Here's a presentation describing our approach....
Question to the old timers: To what accuracy (titrant volume increments) do you titrate? I started out titrating to the ml, now to the 1/2 ml. I use a pipette,...
I have a burette but for me it's too much of a hassle to use. So I use syringes from my vet. The rubber on the oil one holds up well because I have learned to...
Thanks. because I can get repeatable results to the 1/2 ml, I'll stick there ... and not worry too much about it. A burrette would be much more of a hassle. I...
... Hmm ... can anyone say *from personal experience* that a HWH will collapse under low vac? Please tell me only if you know, don't reply with an opinion no...
I don't know anyone who has collapsed one although two members of the St. Louis Biofuels Club have cracked the fiberglass linings of larger HWHs with vacuums,...

Maud, and the Methanol "Recovery" types.. I joined the STL group, to read on your methanol recovery methods. Fascinating stuff-- since biodiesel is about...
... That's what I've done. ... Can't speak for you, but I'd never get _anything_ done unless I started small and progressed. Trying to get all going at once is...
Thanks, AJ! We have had several Club members try a combo all-in-one approach to processing and methanol recovery with the same unit and they have all abandoned...
Lan, I think you can get smaller propane tanks for $25 or so. So if you collapse one as part of your pre-recovery testing it won't be the greatest loss in the...
Can anyone tell me (in detail) how to fab a methanol recovery system (vacuum type) I think that I have most of the matetials and I have a good idea about how...
Oh, you and Graydon have convinced me. I'm grateful ... you've also saved me time and maybe a nasty event. So I'm thinking a 25-gal propane tank (about the...
I think you people are on the wrong track. At 29"Hg you should be able to recover methanol at 0*F. At 29"Hg you can boil water at 65*F. At 105* F you ...
That is magical thing Maud. If you think about it for a minute you will realize that you CAN'T collapse one that is full. You can only get it to deflect a bit,...
Hi Layton, Take a look at our group's web page on Yahoo: http://groups.yahoo.com/group/biodieselbasics. There's a bunch of resources listed there. Probably...
Maud, In your presentation you mention that you can recover about 25% methanol by volume of glycerol. How much methanol can you recover from the freshly made...
Jason, What would you suggest on vacuum and temp to do this? Del Jason J <duecento@...> wrote: I think you people are on the wrong track. At 29"Hg you...
