About the Course

This test method covers the determination of nitrogen in liquid hydrocarbons, including petroleum process streams and lubricating oils in the concentration range from 40 ug/g to 10,000 ug/g nitrogen. For light hydrocarbons containing less than 100ug/g nitrogen, Test Method D4629 can be more appropriate.

The course can be completed in approximately one hour.

Learning Outcomes

By the end of this course, you will be able to:

• Describe the apparatus needed to conduct this test method

• Recall the requirements for sampling

• Describe the steps for preparing the apparatus

• Identify the calibration and standardization procedure for the two alternative injection procedures available: the volumetric and the gravimetric procedures

• Recall the procedure for the determination of nitrogen in liquid hydrocarbons

• Recall the calculations used to determine the nitrogen content of the specimen based on which analyzer calibration method was utilized

• Identify the requirements for reporting nitrogen results
