We have several used/reconditioned centrifuges from Alfa Laval and
some from Westfalia, for sale. They are not as expensive as the
prices you may see thrown around. Contact us for a actual quotation
or visit us online at www.dolphinmarine.com
Thank you.

Hi James, we have been using dairy cream separators to continually
remove glycerol. There are some problems though if the glycerol
gets
cool too quickly it clogs up the plates. A simple precipitate trap
like the water trap in a fuel line only bigger has given good
separation at times. Its just a 4 pipe with the inlet and out let
pipes at the top. The inlet goes down a few inches through a mesh
screen. The outlet is above the screen. I use a tap at the bottom
to
remove the gycerol etc. The volume of the pipe is determined by the
batch size, leave room for all of the glycerol. In series with the
dairy separators this trap helps to overcome clogging. The methanol
is added to the pickup after the separators and mixes in the
centripital pump. The methoxide is added a little at a time so that
the glycerol is produced slowly, over at least 1/2 an hour. Still
pretty quick for a batch method. I haven't done much with washing,
separation of soapy water and fuel seems to need more speed than we
can muster. Regards from Harry

Hello,
can anyone give me a rough idea of the types of centrifuges or
liquid
liquid
separation equipment that could be used for the separation of
glycerol
from
biodiesel, and the separation of water from biodiesel. (as in
after
washing)
I have no expertise in this kind of equipment and would
appreciate
greatly
any help on the matter. I am aiming at a plant to produce 15000
litres of
biodiesel per week.
