Hydro-cyclone separation is a good idea in principle. From my experience
with these, I should think you will be looking at a bank of several small
diameter units manifolded together on all three pipes (inlet, apex and
vortex finder). If these are above the reactor and uninsulated, the

Thanks for the tip.

We are interested to design the use of solar enegy instead of wood as
fuel and looking for the innovative design. Is there any one who already have
done this design for recirculation using thermo siphon without pump , solar

Hi Jim
I made a mixing vessel from a 30 litre water pressure tank cut in half,
welded onto the ends of a 1.2 meter high cylinder (capacity of 160
litres) I used a 1/2 hp transfer pump with brass impeller, and I'm glad
I tried it with vegetable oil first. It would only run for a few minutes
Has any successfully used a small recirculating pump to mix
during the reaction time? A 1/4 hp Grunfos with nitrile, brass or
other impellers should work. The amount of electricity used
would be low. The pump outlet would lead to a circular
manifold at the bottom of the tank with a
I use a 700 watt power drill to mix 180 litres of oil/methanol. It's
not an efficient motor, but suggests you'd need at least 5KW into a
300 gallon tank. 3 phase is more efficient so you might get away with
4Kw.
The milk bulk tank mixers I've seen are really only stirrers.
They'd struggle

Subject: [biofuel] Mixing times for complete reactions
I know that there are differing beliefs on this list as to required
mixing times for reaction completion.
