COLD FILTERED BIODIESEL

FUELS THAT DO NOT CLOG FILTERS OR GEL IN TEMPERATURE-SENSITIVE APPLICATIONS, THE FUELS BEING PRODUCED BY A WINTERIZATION PROCESS OF (1) CHILLING AN ALKYL ESTER TO THE CLOUD POINT, (2) ALLOWING/ENCOURAGING WAX PARTICLES TO FORM; (3) CENTRIFUGING OR FILTERING OUT THE FUEL, AND (4) FURTHER CHILLING TO CAUSE MORE WAX PARTICLES TO FORM; (5) REMOVING THE WAX PARTICLES UNTIL THE CLOUD POINT OF THE FUEL IS SUPPRESSED TO AN ACCEPTABLE LEVEL
