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.

Hello JosŽ:

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).

Best regards,

Mauro Ariel Knudsen

  Hello Jan:
 
  All the oils have some diferences, depending of
  quantity of carbon chain and the quantity of
 single,
  double or triple bond between the carbon atoms.
  This 2 features will be the most important for
 quality
  oil and will be determinatings for 2 parameters:
  IODINE NUMBER: this is one kind of measure to know
 how
  satured or insatured (quantity of single, double
 or
  triple bond between the carbon atoms)is an oil.
  The oils with high iodine number has lower gelling
  temperatures and the inverse. The norm E DIN 51606
  limit this number in 115, but I thinck that is a
  political limitation, because with this limit
 the
  rapeseed is able to biodiesel and sunflower and
  soybean aren«t. The europeans don«t want introduce
 the
  soybean cultivation in Europe. In USA this
 parameter
  don«t exist.
  CETANE NUMBER: this is a important parameter of
  efficience in the combustion, and is determinated
 by
  the long of the chains, it«s uniformity and the
  saturation of the oil.
 
  When a oil is more satured have more cetane number
 but
  higher gelling temperatures.
 
  When a oil is more insatured have less cetane
 number
  but lower gelling temperatures.
 
  Look at this information:
 
  This are diferent oils with their melting
 temperatures
  as: oil, methil esters, ethil esters and their
 Iodine
  Numbers and Cetane numbers.
