I guess you didn't read the abstract which says that settling time IS
also reduced with ultrasonics (although I don't understand the
mechanism or how that works).

In fact I use mechanical stirrer wich means there is no heat loss in the tubes outside tubes, and the mechanical energy remains in the reactor also as heat.Other thing is that the reaction time is 10 or 60 or 120 minutes doesn't matter. the reason is that you have to settle for 12 - 24 hours anyway. in my point of view speeding up the settling would be something much more logical direction to go. Another reason for this is that the 2 stage mathods require a re-heating, which could be avoided if separation was compete in 1 hour vs. 24 hours Keep going Andrew ----- Original Message ----- From: "Joe Street" <[EMAIL PROTECTED]> To: <Biofuel@sustainablelists.org> Sent: Friday, March 31, 2006 3:49 PM Subject: Re: [Biofuel] Glycerine use and other fancy stuffHey Greg ; If I run my reactor (which has a 1500 watt element but is a 220 volt unit running on 110v) I am consuming 350 watts and current wisdom says to allow 1 hr or more for the reaction so that's 350 Wh of energy used. If I use a 300 watt US generator and the reaction completes in 10 minutes that's only 50 Wh of energy used. for the u-sonics and another 58 Wh for heating during that 10 minutes, but in fact the insulation will keep the mixture hot for that amount of time so I can get away with just 50Wh of energy. Plus if the abstract is right I use less catalyst and less excess methanol and you have to consider the energy that went into producing those as well. All told it is a significant savings!

If the idea is to use renewable fuels, how much electrical energy from the natural gas fired generating plant will be used to speed up an equlibrium process? I think too much to keep with the ideals. I don't mean to be critical. I ain't been here long enough for that. And the people here have such a strong hold on the concepts, I am just wondering if/what I am missing? respectfully, Greg Kelly_______________________________________________ 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 (50,000messages):http://www.mail-archive.com/biofuel@sustainablelists.org/_______________________________________________ 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/ |
