Need advice on low cost wvo processing.

Postby Radrick » Tue May 20, 2008 9:28 am

I have had so many expensive repairs to my truck recently and fuel is costing my so much that I am having a hard time getting the components together for my conversion and processing setup. I can afford to purchase the components for the truck but if I do that I can't afford the centerfuge. So I am wondering what my best choice is for a cheap wvo processing setup that can get me by for a few months until I can save enough to buy a centerfuge. I was planning on setting up the wvo processing system first since there isn't any reason to have the truck converted until you can provide fuel. Also I would like to make certain that the fuel is processed correctly so that I have the lowest possible risk of damaging my IP and engine, this is why I was planning on using Sun's setup from the get go. Any advice or opinions are welcome, I am just looking for my best cheapest options.

John,
How often do you have to clean out the sludge? Will the system work in the summer at 90f or does it need to be at 65f or below? What did you use for the 10 gallon container? I already have five plastic 55 gal drums, I assume the main settling drum can be plastic. Can I use a 55 gal drum for the second stage drum if only let it fill 2/3 the way up? I already have the pump for the centerfuge if I slow it way down I'm thinking I can use it for the final filtering instead of buying a drum pump. Thanks for the feedback.

How much sludge is in the oil you will pour in?

It won't separate hydrogenated oil and fats above 65.
What did you use for the 10 gallon container?

a 10 gal barrel I had handy; it holds two cubies of oil, any size will work

John's system is great. You can read about another low cost, no energy consumption option http://biodiesel.infopop.cc/eve/forums/a/tpc/f/159605551/m/5421073512?r=5421073512#5421073512 here.

For filtering I use a 200 micron drum screen then three sediment filters (20-5-1u) followed by a 1 micron absolute final polishing sock filter.

For de-watering I use THIS STANDPIPE DESIGN. The drum is well insulated with R-13 and aluminum bubble wrap so the s-l-o-w cooling lasts up to 72 hours from 160*F with my band heater. Passes the hot pan test every time.

The link you provided is discussing a water wash system for Bio. Is it nessisary to water wash wvo? what are the risk/benifits of doing this? Or are you just using this for removing any existing water?

No, but some do it to VO, see:
Mistwash Rig
He says he doesn't mistwash in that thread, so it must be for settling out suspended water.
