The Dallas Group of America Inc., the company behind Magnesol dry wash, is offering a new line of adsorbents to help biodiesel producers purify their fuel and pass the cold soak filtration test (CSFT). Called D-Sol, the new product line removes sterol glucosides and other contaminants that cause CSFT failure.

D-Sol can be used either during regular dry wash purification or as a post-purification treatment after water-wash or ion exchange purification.

The Dallas Group reports that when D-Sol is used as a part of the regular adsorbent purification process, the incremental cost to the producer is zero. When utilized as a post-purification treatment, the incremental cost is between 1 cent and 2.5 cents per gallon.

Unlike other post-purification filter treatment systems, D-Sol works at normal process temperatures so there's no need to waste time and energy chilling the fuel down prior to filtration.

For more information, call the Dallas Group at (800) 367-4188.
