@Veikra Yeah, that is what happens when you run dual electrical 24V and 12V systems in your rig. I've since converted the truck to all 12V ;) Also found a bad ground on the compressor pressure switch which is why I had to jerry rig the compressor on the truck to make it run.
In this first revision we pumped it into the top of the main mix tank but we found the methoxide just floated on top and did not stir well. The second revision we used the main mix pump to suck the methoxide in at a slow rate. This allowed the oil in the tank to turn over about 5 times in the mount of time it took to introduce the methoxide. We would take a sample just after the methoxide was 100% introduced and set that jar aside and found the 20% glycerin split without any more mixing.
We did however let the main mix pump run for 2 hours just to be on the safe side mixing the oil methoxide mix after the methoxide was fully introduced. Results were slightly better then the sample we took with no mixing so continued to use that process.
I copied my little 2 tank 40gallon batch processor, which I intern copied from all the other makers of processors: biodiesel solutions, extreme biodiesel, etc all use the same design. They wanted $3000+ for a 40 gallon system, you can buy the tanks and build it yourself for $600. This larger one I believe cost us in the ~$6000 range. $3000 along for tanks and shipping. ~$1500 for pumps. Not sure what the pumbing cost us.
Turn on the water line running to the misters hat are moutned in the tip of the tank. That water sinks to the bottom and over hours of running you will see a layer of water growing on the bottom because the biodiesel floats on top. Drain the water off the bottom by opening a valve on the bottom.
Keep misting and draining every few hours till the water you drain is clear.
I have a question: the one thing I can't figure out after hours of research is how the washing process works. I get the boiling and all that, but how is the stuff taken out? does it just evaporate with the water, or does it get skimmed off? Could you answer this?
Water washing is simply misting water on the top of the biodiesel. It settles on the top then as the droplets get big enough and heavy enough they sink though the biodiesel. As they sink they pickup little bits of left over lye, methanol and other contamanents and drop them to the bottom. You drain the bottom several times.
Once the water wash water on the bottom is clear as the water you put in you done washing. On to the Dry process.
I prefer to heat the biodiesel to about 100-120F again after the wash is completed. I move mine into the dry tank which has a "sprinker" type slit in the end of my 2" pip that sprays the biodiesel exposing it to as much air as possible. I also have a fan blowing air into the tank. Since the biodiesel is warm, air is applied, and I'm spraying the biodiesel I end up with a completly water free batch in about 4-8 hours.
Nice setup, however I was told to prevent oxidation of the oil at all costs in order to prevent polymerization with High iodine Value oils. (The gummy, plastic like, sludge and the scourge of every IC engine) Is there a way to dry without exposing it to air? Thats the only qualm I had but great video.
Email me and I can get you some information. I have lots of charts and diagrams that I wish I had when I first started and will help you jump right into it.
Not sure actually, they have 2.5GPM stamped on them but they pump proboubly 2 gallons every few seconds when they run. With a 1.5" input and output on the pump it pumps with some pretty good pressure.
The smaller transfer pumps are little harbor freight ones. Methoxide mix tank uses sparkless air powered pump. I can transfer 55gallons of methanol in a few minutes.
For oil we are using waste vegitable oil from resturants that can be a number of sources from: canola, peanut, etc.
Not that I imagine it would mean that much to you, but I personally applaud the sentiment in the video comments.

Do you manually introduce the catalyst into the methoxide tank? Or is it pumped in somehow ?

another question, did you make the plans for that up or did you find one in a catalog or something? that looks pretty complex

so you pretty much open a nozzle on the bottom of the tank and wait till it turns clear?

Hey just wondering if you would like to automate your processor with a PLC.

hey is there anyway u can call me so we can discuss ur processor because im opening my own business and some helping advice would help. thanks!!

What heater are you using an about how much were the pumps you use.
qzerweazel 3 years ago
The heater is huge. 2" diamter, 4 foot long, heats 275gallons of oil to 130F in about 4 hours.
Pumps are 220V run about $500 each.

Where did you get that large of a heater and those pumps.

nice system man ... just wondering tho what r ur pumps rated ... and whats ur source(is it corn) for the biodiesel?
