Description

UOP 384 – Nitrogen in Petroleum Distillates and Heavy Oils by Acid Extraction or Direct Kjeldahl Procedure

This acid extraction method is specifically intended for the determination of combined nitrogen in petroleum distillates and heavy oils in concentrations ranging from 0.1 to 100 ppm. Non-extractable samples, and samples containing nitrogen concentrations ranging from 20 ppm to several percent, can be handled by a direct Kjeldahl analysis. The method applies to oil samples as well as a large variety of other materials; e.g., corrosion products, deposits, catalysts, etc.

The types of nitrogen compounds which can be determined are those which usually are determined by a macro-Kjeldahl procedure and include amines, amides, pyridines, pyrroles and quinolines. The method does not apply to organic nitro-compounds or to those containing a -N = N- linkage.
