Значение и использование

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.

Область применения

1.1 Thistest method covers the determination of nitrogen in liquidhydrocarbons, including petroleum process streams and lubricatingoils in the concentration range from 40 μg/g to 10 000 μg/gnitrogen. For light hydrocarbons containing less than 100 μg/gnitrogen, Test Method D4629can be more appropriate.

1.2 Thevalues stated in SI units are to be regarded as standard. No otherunits of measurement are included in this standard.

1.3This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety,health, and environmental practices and determine the applicabilityof regulatory limitations prior to use. Specific warning statements are given in Section6, 7.1, 8.2, and 8.2.2.

1.4This international standard was developed in accordance withinternationally recognized principles on standardizationestablished in the Decision on Principles for the Development ofInternational Standards, Guides and Recommendations issued by theWorld Trade Organization Technical Barriers to Trade (TBT)Committee.
