Efficient, Reliable, and Rapid Moisture Determination Using Superior and Proven HYDRANAL Reagents
Residual moisture from the manufacturing process may remain in the finished B100 biodiesel product. It can also be introduced after manufacturing due to condensation in storage tanks. Moisture in a fuel is very undesirable and can lead to many problems:
Reduces the heat of combustion, thereby increasing engine stress.
Corrodes fuel system components.
Allows gelling of fuel in cold temperatures through ice crystal formation and nucleation.
Accelerates the growth of microbial colonies which can clog fuel systems.
ISO 12937 specifies a coulometric titration procedure for the determination of moisture in B100 biodiesel samples. This procedure is based on Karl Fischer titration chemistry. Other procedures based on Karl Fischer, such as by coulometric titration with a Karl Fischer oven and also by volumetric titration, may also be suitable.
