Lanlang CA005DR is a special commercial grade dry wash ion exchange resin that can be used to remove impurites from Biodiesel after the glycerin has settled and been removed. It works extremely well at removing soaps, catalyst, glycerin, and even water. When used as recommended and in tandem with a demethylation system, it can allow you to remove the contaminant levels in Biodiesel down to ASTM specifications.
How It Works?
CA005DR biodiesel purification ion exchange resin is placed inside of a holding vessel. Typically the vessel employed is tubular and is referred to as an Ion Exchange Dry Wash Tower. The resin beads, when deposited in the column, form a "resin bed" at the base of the vessel. Unnwashed Biodiesel is then pumped through the vessel and through the ion exchange resin beads.
As the Biodiesel flows through the beads, the impurities are removed and the Biodiesel is purified. This biodiesel purification ion exchange resin product purifies the Biodiesel by working at a molecular level through a process called ion exchange. This product literally exchanges sodium or potassium ions in the soap in the Biodiesel for hydrogen ions in the resin. This means that it breaks the soaps apart and keeps part of the soap molecule and gives up part of a hydrogen molecule, resulting in Biodiesel with extremely reduced soap levels.
Here's some example life expectancy estimates:
5 lbs - between 625 to 875 gallons
10 lbs - between 1250 to 1750 gallons
20 lbs - between 2500 to 3500 gallons
50 lbs - between 6250 to 8750 gallons
70 lbs - between 8750 to 12250 gallons
100 lbs - between 12500 to 17500 gallons
120 lbs - between 15000 to 21000 gallons
250 lbs - between 31250 to 43750 gallons
500 lbs - between 62500 to 87500 gallons
There should be no more than 2000 PPM (Parts Per Million) of total impurities (glycerin, soap, unused catalyst and other trace impurities) in the Biodiesel to be dry washed but less than 1000 ppm is highly recommended. Otherwise, the resulting Biodiesel can become too acidic.
If soap levels are higher than 1500 PPM, we recommend pre-treating the Biodiesel with a cellulose media product prior to running it through CA005DR Dry Wash Resin.
