Jet fuel, crude oil, Diesel blends: Applied NIR-Spectroscopy – quality control of hydrocarbon refining

May 20 2016 Read 959 Times

 

Near-Infrared Spectroscopy (NIRS) enables straightforward multi-parameter analysis of critical parameters for monitoring the refining of hydrocarbons. NIRS is a non-destructive secondary analysis method, NIRS does not require any handling of chemicals whatsoever, and real time measurements are performed at the push of a button.

 

NIRS is the ideal method for a wide range of applications:

  • Distillation of crude oil: API Gravity, Reid Vapour Pressure (RVP), density, PIANO
  • Lubricant oils: aromatics content, density, flame point, oil content, PAH, pourpoint, distillation analysis, viscosity
  • Diesel blends: cetan index, cloudpoint, density, FAME, colour, flashpoint, etc.

Metrohm provides a comprehensive portfolio of NIRS instrumentation for laboratory and process analysis as well as a large number of documented applications (Application Notes). Among them are:

 

  • AN-NIR-022  Petroleum product analysis by NIRS (cetane index, TAN, aromatics, and sulphur)
  • AN-NIR-024  Measurement of diene value (DV) by NIRS
  • AN-NIR-025  Real-time inline predictions of jet fuel properties by NIRS
