Cold Soak System

Filter plugging both in the ASTM procedure and in the field has been researched significantly with a range of answers to the single question. Most producers and consumers assumed poor cold flow performance was due to feedstock issues, or even poor biodiesel quality. When data started coming in from biodiesel producers around the nation, the answers became even more confusing. A wide range of cold soak results were found for biodiesel samples from a wide range of feedstock and an even wider range of producers. Obviously the cold flow problem was not just quality or feedstock dependent.

Methes Energies has designed a multi‐stage filtration / absorption system that ensures that any potential factors that would initiate crystallization or plugging on the filter do not occur. By sequentially removing certain impurities that create a higher than normal likelihood of surface crystallization on the filter, our filtration system ensures that your biodiesel can meet the ASTM specification for cold soak filtration. It also ensures that your customers are receiving the very highest quality biodiesel and will minimize system plugging quality issues.

The system is designed to be a single pass four‐stage bank of filters/absorbers that sequentially remove those compounds likely to cause filter plugging. The filter elements are disposable and easy to remove from the filter housings. Multiple units can be run installed in parallel to achieve higher flow.
