Determination of Trace Level Total Nitrogen content in aromatic hydrocarbons according ASTM D7184

Oil refinery at dusk.

The Total Nitrogen content in liquid hydrocarbons and aromatics like benzene plays an important part in the manufacturing process of these chemicals and is essential for
adherence to stringent pollution laws. The Total Nitrogen content has also been found to be critical to the effectiveness of catalysts and shortens their lifespan, which affects
the cost of operations dramatically. This causes problems for petrochemical plants which have moved into the production of light products whereby catalysts play an important role in those processes. Aromatics and olefins are particularly susceptible to nitrogen effects when they are saturated by a hydro-treating process. This application note describes the principle of operation and performance of the TSHR 7000 Total Nitrogen Analyzer for the determination of Total Nitrogen in liquid aromatic hydrocarbons according to ASTM D7184 methodology.

Our Impact

TSHR has been helping labs achieve their elemental analysis goals with dedicated solutions. Our vision is to develop innovative reliable combustion analyzers that enable customers to make their work productive and more easier.

To help labs excel we offer Application Notes across the Combustion Analyzer product line. They are a resource that explains the technology, performance, and abilities of our products as used against certain methodologies and or applications.

Whether your needs center around an ASTM Standard or EN/ISO methods, or a sample matrix-based outcome TSHR has you covered. If you don’t see the technical direction you need, simply contact us. We also offer sample analysis in our onsite Applications Lab.
