Re: [Biofuel] liquid liqid centrifuge
You're only turning 1400-3000 RPM. How many people do you know cutting on engines that are running 6,000 rpm or more. I know I've seen a lot of them go wrong, but they're normally not sending things flying in every direction. And belive it or not most of the time they work. Also the fact that liquid is spinning should help adjust any off balance and smooth out the rotation. http://www.rousselet-robatel.com/products/extraction3.php I am planing on useing one of their BXP 130p for my setup. I was quoted 15,500US. for rebuilt, 27,800us for new. I know that's a lot for the average person makeing it in their backyard, but I am setting up for production in south Louisiana.

[Biofuel] liquid liqid centrifuge
has anyone tried a liquid liquid centrifuge. By continuously removing the dense gycerine you would drive the reaction forward requireing less methanol (the whole pont around the two step reaction) please see http://www.cheresources.com/centcontactor.shtml I think it would be possible to build something along these lines cheaply, take that old blender and put it inline with your reactor? mike in San jose ca ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/

Hey Mike. The NH Coop that Mike Briggs works with has an line-in centrifuge, but as far as I know, they only use it to skip settling, not to reduce the amount of methanol.

They do speed up the process as you don't need to wait for settling to occur, which also means that you don't need extra tankage. See my comments in the archive from a few days ago regarding OFM mixing and centrifuges. Before you start planning to build something along these lines cheaply, remember that these things are made of steel and spin at many thousands of RPM's. Unless you're very good at machining and milling you could be making a potential bomb, you only need something only the slightest bit out of balance and the thing will tear itself apart spitting shrapnel everywhere. I've seen pictures of when lab based centrifuges go wrong and it looks like someone tossed a hand grenade into them. I've also heard of an installation of several CINC, that's the company that provided the info in the above mentioned link - Kevin Costner owns it, centrifuges at a biodiesel plant here in Australia where they couldn't get them to work properly. The plant eventually dumped them and went for a standard Alfa Laval type of thing. Don't let these comments put you off centrifuges. Do some web searchs and no doubt you will come across second hand/excess/scrapped centrifuges. They still might not be cheap, but then again, it would make a nice experiment.
