Greenhunter Biofuels Announces Distillation Capabiliites in Advance of Cold-Soak Filtration Test Effective Date
In October of 2008, ASTM International, originally known as the American Society for Testing and Materials, added the “Cold Soak Filtration Test” procedure to its mandated biodiesel testing methods. The stated goal of the Cold Soak Filtration Test is to protect against the precipitation of solid materials in inferior biodiesel during cold weather and to ensure that end users will not have problems with their engines when using biodiesel in cold temperatures. Material that does not pass the Cold Soak Filtration Test and other ASTM specifications cannot be sold in the United States as biodiesel after April 1, 2009. Management of GreenHunter believes that most of the biodiesel currently being produced globally will not pass the minimum requirements of the Cold Soak Filtration Test and will therefore have to be further refined using a distillation process.
