even with a diaphragm pump?

 

Tom was talking about a centrifugal pump. Using a diaphragm pump is fine ( it's what I use). Using a centrifugal, or gear pump is problematic. When Magnesol is mixed with raw biodiesel it swells up. Using anything but a diaphragm "shears" those swollen particles, and makes it harder to remove.

 

that is what I thought. I have a pump on order. It took 2 hours for me to filter 4 gallons and figure the pump will help a lot. thanks for confirmation.

 

Do you have a link for the pump you ordered?

 

Thanks Don. Not to get too "nitt-picky" but is that 10 micron absolute or can we let a few of those rascals sneak through my regular 10 micron filter without any sheering problem? Tom

 

Just for you Tom............We can let a few rascals sneak through

 

Thanks Don. I will sleep better tonight knowing the little rascals won't be swimming around in my bio trying to avoid getting sheered.

 

Where did you get your diaphram pump? Did you check around for a decent price? Is it manual or motorized? Thanks Tom D.

 

northern. electric of course- $250.

 

US Plastics Corp (www.usplastic.com) has a Guzzler Large volume Hand Diaphram Pump that is pretty reasonable. ($46.02 for a 10 GPM). Do you think that would work OK? I'm trying to keep costs down and $350 is a bit much for no more than you need to use it. I will transfer through it only when I need to pump with Magnesol in the bio. It would take approx 8 strokes to move 10 gal.

 

How do you determine how much magnesol you use. I saw the test stuff and it looked kinda confusing to me on doing to whole acid thing. Also I am using a water irigation pump and only filter to 200 micron for the oil. Will this pump work for the filteration process. Thanks.

 

I don't have as much experience as most of the biodiesel guys in this forum, but I use Magnesol without mechanical pumps at all. My entire processor moves liquid off the pressure and suction of a cheap WalMart compressor and my processing tanks are steel. Once I have drained my glycerine I :

- Blow the fuel into a 94 gallon open stock tank and aereate until I know the methanol is gone. The stock tank is elevated so it is above the top of a 275 gallon tank.

- Add 2 grams/liter of Magnesol and stir with an air drill and pain stirrer for 30 minutes. Let it settle for a minimum of 2 hours and if possible overnight.

- Gravity flow into the tote through a 5 micron sock inserted into a 1 micron sock, and both are inserted into another 1 micron sock. (32" x 6" socks).

- Once in the tote I vacum it through a 2 micron Biotech canister filter into an old 120 gallon water tank. Then I blow it back through the sock filters into the tote and through the 2 micron canister filter a second time just because I can.

- From there I pressure it through a 1 micron Biotech and finally through a 1 micron absolute into the transfer tank in my truck.

- Before I run the next batch I scrape the settled Magnesol out of the stock tank.

It really doesn't take much time and I can read newsprint through 3 inches of biodiesel in a glass beaker.

Purolite and Amberlite require too much residence time to be fast enough for the average homebrewer. I think Amberlite instructions are 0.3 gallons per pound of Amberlite per hour. A soda keg holds 10 lbs of Amberlite, so that comes to a whopping 3 gallons per hour!

Sorry if I bored you all with this reply.

 

from what I have read though, that seems a little on the low side. I have seen some people that are running with like3.5 pound per batch for a 40 gallon batch. your method only uses like 11 oz. Please unconfuse me. I have been making this stuff for like 4 years now but I am new to dry wash. Thanks

 

If you don't recover or remove the methanol it requires 2 percent by Weight.
40 gallons at 7.5 lbs/gal = 300 lbs. 2 percent would = 6 lbs of Magnesol.

If you remove the Methanol, and filter out the soap, you can use 1 percent Magnesol, or 3 lbs magnesol / 40 gallon batch.

 

Follow this link to Fryerpower.com (MAGNESOL R60 and D-Sol (D60) at FRYERPOWER HOME). Read that page and then go to the Burlington Biodiesel link.

I do take pains to demeth thoroughly, I am passing the 3/27 test, and the clarity is great. At first I did not believe it would work and clear up such cloudy fuel, so I used a whopping 3 grams/liter.

Besides, the methanol has to come out sometime anyway.
