Total Nitrogen Analysis in Liquid Hydrocarbons Compliant to ASTM D5762

Oil refinery at dusk.

ASTM D5762 covers the determination of Total Nitrogen in liquid petroleum products and lubricants in concentrations ranging from about 40 to 10,000 mg/ kg.

Nitrogen compounds can have detrimental effects on many environmental and industrial processes and are undesirable in finished products. Nitrogen containing hydrocarbons seem to be the hardest to hydrotreat, meaning that the nitrogen content in the product of the hydrotreater is a measure of the effectiveness of the hydrotreating process.

This supports the need and importance to monitor trace level nitrogen concentration of various type of automotive fuels and related products. This Application Note shows the Total Nitrogen analysis performance of a set of liquid hydrocarbon samples, by the EST NEXIS model Total Nitrogen analyzer.
