Cetane Number of Diesel Fuels #3010 - Oil, Gas & Refineries - Refineries

The Cetane number of a diesel fuel is a measure of the ignition properties and is an important specification that must be met during fuel production. The traditional laboratory method for Cetane number determination is the knock engine method in which the fuel is burned and its combustion characteristics compared to known standards. This method is time and labor intensive, and provides no ability for real time control of production. This note discusses the use of Guided Wave hardware and software tools for the measurement of Cetane number in diesel fuel using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR is applied in real-time directly in process monitoring or as a laboratory procedure. In either case NIR is a time and money saving alternative to traditional methods.
