ASTM D5762 - Nitrogen in Liquid Hydrocarbons, Petroleum and Petroleum Products by Boat-Inlet Chemiluminescence
Significance and Use
4.1 Many nitrogen compounds can contaminate refinery catalysts. They tend to be the most difficult class of compounds to hydrogenate, so the nitrogen content remaining in the product of a hydrotreator is a measure of the effectiveness of the hydrotreating process. In lubricating oils the concentration of nitrogen is a measure of the presence of nitrogen containing additives. This test method is intended for use in plant control and in research.
1.1 This test method covers the determination of nitrogen in liquid hydrocarbons, including petroleum process streams and lubricating oils in the concentration range from 40 μg/g to 10 000 μg/g nitrogen. For light hydrocarbons containing less than 100 μg/g nitrogen, Test Method D4629 can be more appropriate.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.Extracted, with permission, from ASTM D5762-18a - Nitrogen in Liquid Hydrocarbons, Petroleum and Petroleum Products by Boat-Inlet Chemiluminescence, copyright ASTM International, 100 Barr Harbor Drive, West Conshohocken, PA 19428.
