Cloud Point of Diesel Fuel #3074

The Cloud Point of a diesel fuel is the temperature below which wax forms giving the fuel a cloudy appearance. This parameter is an important property of the fuel since the presence of solidified waxes can clog filters and negatively impact engine performance. The traditional laboratory methods for the measurement of Cloud Point are optical in nature, but rely on cooling the fuel for the wax formation to occur. Guided Wave’s process analyzers can measure compositional changes in the fuel that will be directly related to the wax formation and hence the Cloud Point. This note will discuss the use of Guided Wave hardware and software tools for the measurement of the Cloud Point of diesel fuel using fiber optic-based, near-infrared (NIR) spectroscopy. NIR can be applied in real time directly in process.
