Dual Cold Soak Filtration Refrigeration System



For the determination by filtration time after cold soak of the suitability for a biodiesel (B100) blend stock that meets all other requirements of Specification D6751 and has a cloud point below 68°F (20°C) to provide adequate low temperature operability performance to at least the cloud point of the finished blend. 300 mL of biodiesel (B100) is stored at 40 ± 1°F (4.5 ± 0.5°C) for 16 h, allowed to warm to 77 ± 2°F (25 ± 1°C), and vacuum filtered through a single 0.7 μm glass fiber filter at controlled vacuum levels of 21–25 in. of Hg
