Not sure if Magnesol will work for your application? Try this 10lb bag.
What is Magnesol? How much Magnesol do I need to clean biodiesel? Magnesol D-SOL is a synthetic magnesium silicate powder. D-SOL cleans B100 by adsorbing the impurities. The impurities are attracted to and stick to the D-SOL. The manufacturer of Magnesol D-Sol is The Dallas Group. They recommend the use of .05% to 1% by weight of Magnesol D-Sol to clean B100. Start with the .1% by weight and test the washed B100. The ratio can be lowered based on the test results. A gallon of B100 weighs approximately 7.3 lbs. To find the amount of Magnesol D-Sol to wash 50 gallons of B100 the formula is:
.01 x 7.3 x 50 = 3.65 Lbs of Magnesol D-Sol
To clear up some misinformation found on the internet. There are sites that require that you test for soap content and then input the soap number into the equation. This is NOT correct. The soap number is relevant for another product made by The Dallas Group called D-Sorb which is used for a completely different application. Again, it is not used in the Magnesol equation. Magnesol removes all the impurities from B100, not just the soaps.
In order to calculate the amount of Magnesol to use prior to washing, the B100 will need to be tested for all the impurities, not just soaps. It is much more feasible to test the washed B100 and adjust the ratio accordingly. Another misconception is to use the specific gravity of wvo or B100 in the equation. The specific gravity of wvo should never be used since the product you are washing is B100, not wvo. Specific gravity is the measure of a fluid density in reference to water. Therefore the equation would multiply the gallons by the weight of water and then the specific gravity of the fluid for an accurate result. For example the specific gravity of B100 is approximately .88 and a gallon of water weighs 8.3 lbs. The formula is:
.01 x 8.3 x .88 x 50 = 3.65 lbs of Magnesol D-Sol
As long as the weight of B100 per gallon is used, the specific gravity is not needed.
The process of using Magnesol to wash B100 is simple. Drain off the glycerin, reclaim the methanol or heat the B100 and allow the excess methanol to evaporate off. While the B100 is still approximately 140°F and being agitated, add the amount of Magnesol based on the equation above. Let it mix for 20-30 minutes. At this point you have 2 options. Option 1 is to stop the mixer and let the magnesol settle to the bottom, drain the Magnesol off and then filter the remaining B100. Option 2 is to filter the Magnesol out. A filter bag with a 1 or 5 nominal micron rating will remove the Magnesol. Test the washed biodiesel using the PhLip test. Rewash and retest as necessary until the B100 is clean. Add the pounds used with each washing to get the total amount of Magnesol needed to clean the B100 with your process. Pump the B100 thru a polishing filter such as a Bio-Tek Filter to ensure all Magnesol has been removed. Your B100 is now ready for use.
