ways to double check titration math?

[Lee Haenschen]

I am doing a 302 litre batch of bio-D...is there a website that I can double check my math from my titration?

With my titration it took 3Ml. of tester to get the correct color change (tested 4 time

302.8 ltr batch
66.6 litr. Methanol
2,422 grams of lye

OR
80 gallons
17.6 gallons of methanol
85.5 Ounces of lye

Is this the correct math for this batch??

If my calculations are right it will cost me around $1.03 per gallon to produce
Methanol $2.99 per gallon
Lye $5.50 per 510 gram bottle

What do you guys think? did I get it correct?

Here is a link to a page that has the link to down load the excell spreadsheet.
You have to look down the page some to find it.

YES! That spreadsheet is a definite musthave for making biodiesel.

I put it on an old laptop I got for 75 bucks and use that as my portable Linux/Biodiesel brain for my operation.

Is this titration with NaOH or KOH?

[Spencnaz]

Ok if you are using the following numbers:

3 g/L of NaOH
80 Gallons of Oil
17.60 gallons of Methanol

Results:

Assuming a transesterfication of 78%:

86.38 ounces of lye

At $2.99 per gallon of methanol and .77 per ounce of lye, your cost per gallon will be .91 per gallon to manufacture.
