Ultra-trace Level TN Content in Aromatics UOP 971 method
Very low levels of nitrogen are detrimental to the effectiveness of catalysts used in refining processes. Petrochemical plants which are producing BTX type of aromatics therefore require the ability to monitor the total nitrogen content of feedstocks in the low ug/kg region.
This application note describes a direct injection, oxidative combustion followed by chemiluminescence detection technique for the measurement of ultra-low levels of Total Nitrogen (TN) present in aromatic hydrocarbons in compliance with UOP 971 method.
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.
