1. Scope |
This method is for determining basic organic nitrogen in petroleum distillates. This method may be applied to both colored and clear samples with no difficulty. The range of detection for petroleum distillates is from 0.0001 to 1.0 mass-% nitrogen, while for viscous materials, such as heavy oils, the range is 0.001 to 5.00 mass-% nitrogen. This method may give erroneous results for materials containing bases other than nitrogen compounds (e.g., caustic-washed distillates containing sodium soaps, or crude oil containing inorganic bases). Clear or very lightly colored samples may be analyzed from 0.1 to 1.0 mass-ppm by UOP Method 313. |
