Re: [biofuels-biz] Re: Max capacity and consultant for biodiesel wanted
joe, answer in your em : Subject: [biofuels-biz] Re: Max capacity and consultant for biodiesel wanted 1-What is the maximum capacity of a transesterification(biodiesel) reactor? there is no max capacity per se for batch units, but the bigger they get, the more complex they are as regards process quality control and automatization features. our experience is that several small plants are just as economical as one large one, more reliable and safer to operate, and make better use of human resources. small plants 'in series' have the advantage of a smaller infrastructure requirement, specially as regards electric power. small plants have the added advantage of allowing simultaneous processing of different feedstock's. In other words can I react vegetable(or cooking oils) in a 2,000 gals reactor? What about 5,000 gallons? suppose you can, but have never heard of a batch plant this large. when you get into those volumes you might want to go continuous. Is there a maximum capacity? What about ratio of Height to Diameter? RPM? don't know about max batch plant size. h/d we use in our reactors is ~ 1.5/1. rpm = 500 Any publication on the subject? yes, i'd suggest you start by reading tickel's book, 'from the fryer to the fuel tank'. you can get it from amazon. 2- We are thinking (our local group) on hiring a Biodiesel expert from any country of the Americas (who have had a few years experience in making biodiesel form spent oils) to come down to our place and assist us in the design, start up and training of a small biodiesel plant (from cooking oils). Capacity initially would be of less than 1,000 GPD. State your qualifications, fees etc. best i can do is send you specs of our LC-400 semi-automatic plant. it will process 200 gallons a day. we have been considering selling the engineering and/or franchising the construction, but this might be too small for what you want to do, unless you go the 'serial' route. you will need separate facilities for processing your wvo, and turn it into reliable feedstock. you know the old computer saying, 'garbage in - garbage out' whereabouts are you located, and are you fluent in spanish or portuguese ? cheers, dick. ps : you may also contact me ol : [EMAIL PROTECTED] Biofuels at Journey to Forever http://journeytoforever.org/biofuel.html Biofuel at WebConX http://www.webconx.com/2000/biofuel/biofuel.htm To unsubscribe from this group, send an email to: [EMAIL PROTECTED] Your use of Yahoo!

Re: [biofuels-biz] Re: Max capacity and consultant for biodiesel wanted
Hello Jos: 1_ There`s not maxximum cappacity of transesterification but the most common reactors are between 2000Lts ( 500 gal) to 1 Lts (2500 gal). Whit single reactors bigger than 1 Lts (2500 gal)is more dificult get high efficience reaction; in general for get more daily capacity they add others reactors. the 80% of transesterification happened in the first 30 seconds because of in the bigger reactors the metoxide (mixture of methanol and Na(OH) ) can`t react quickly with all the oil like in little reactors. 2_ I know a consultant in Argentina, look at in www.biodiesel.com.ar , in this page appears a consultant called SOLUTION PARTNERS S.C. they are really experts in biodiesel industry and are the encharged of my project and start up for a continuous plant of 40.000 tn/year (145.000 lts/day).
