mobile processing

I want to make a greaser that will be capable of collecting, processing, and burning the oil onboard. It will be a van or truck, so I can potentially have several barrels and/or fuel tanks.

My main concern is that the usual gravity method to let the sediment and water settle out won't work if I am driving around with the oil sloshing around. I suppose I could weld some baffles in the settling barrels to try to minimize this.

I will be able to heat the barrels, probably will weld a pipe coil in them with quick disconnects to the radiator. But even with a 210 F thermostat I am doubtful that the barrels will ever get much over 150 F, and that may take a few days.

Any ideas for me ?

yeah, id say at least a short school bus would be good, a long one even better, like one of those famous dt466 internationals. also, look into a centrifuge for filtering. apparently, its the new way.

someone just made a post about trying to have an onboard centrifuge that would filter "on the fly". ;0)

Forget about settling and

Forget about settling and filtering. Using a good centrifuge, you can clean you WVO to less than 1 micron in purity. Check out the system at pabiodieselsupply.com. They have a great system for the least money.

On that other comment, centrifuging directly into the fuel line will not work well, because you need to send the WVO through the centrifuge 4-5 times to remove all of the contaminants.

The oil will seperate despite

The oil will seperate despite the sloshing. I have transported unfiltered oil 2000 miles at a time and it has seperated enroute. As far as a centrifuge is concerned, the previous posts are correct when they mention that your oil will need to travel several times through the centrifuge to filter properly. In addition to the centrifuge, I would most definitely have a 5 micron or better filter after the centrifuge to 'polish' the oil before it enters the fuel line. If I were to do it, I would set the system up like this:
-Cherry pick oil at the source in order to minimize filtering/seperating and to leave you with less undesired oil to get rid of.
-Use a 1" gear pump to collect the oil, or build a small vacuum system.
-Have an insulated 55gal drum with your radiator coils to be used a a settling/heating tank.
-From the drum you run it through a centrifuge, just make sure you pull the oil from the top because the junk and water will have settled to the bottom. (You might devise a suction tube that is attached to a float).
-Have the centrufuge mounted to the top of another insulated barrel and run it through 5 or 6 times. Transfer your oil through a final filter while its still hot to your WVO 'fuel tank'.
-The system will not be capable of being totally automated because you will need to clean the centrifuge bowl and change filters after a couple batches.

Hope this helps you out. I have been working with WVO for several years and have learned alot by trial and error. (believe me, 'error' is expensive). I have a very nice centrifuge sitting in the corner of my shop. I have outgrown it and it is not used anymore. It will be perfect for your setup if not overkill. (I have always preferred overkill). It will process 1,200 gallons per hour, but through a 55gal drum you will have ran it through 6x in 15 minutes! I have it attached to a 55gal drum and can let it go for $600 if interested email me at: mattcomaintenance@yahoo.com I am located in southern CA, but i'll ship it if you like. Good Luck, be sure to post pictures and keep us informed on your progress.

Keeping the on board tank

Keeping the on board tank smaller rather than larger will help the system work better.

I would emphasize the above comments about a centriguge and a final filter. I also believe that the premium filters (Fram Tough Guard Bosch premium) do a much better job of final filtering.
