BFM202 Lab – Cloud point measurement of biodiesel

The video describes the importance of performing the cloud point test. The temperature at which solids begin to crystalize in the fuel as it is cooled is called the cloud point. Fuel filters will plug with these solidified particles. The cloud point will help to determine the lowest temperature at which a fuel can be used. Biodiesel has a higher cloud point than No. 2 DF. B100 is pure biodiesel and is not good to use in cold weather applications. B20 is a 20% mixture of biodiesel with 80% petrodiesel and has a similar cloud point as No. 2 diesel. Cloud point depends on the feedstock used to produce the biodiesel. Biodiesel produced from animal fats have a higher cloud point temperature than that produced from vegetable oil.
