Course Highlights

This online engineering PDH course explains how nitrogen oxides (NOx) are formed, their impact on the environment, and specific control technologies and solutions. This course further explains the principles on which all NOx control and pollution prevention technologies are based, available NOx technologies for various combustion sources, and performance and cost of NOx technologies.


This 4 PDH online course is intended for environmental and chemical engineers as well as other professionals working in the field of air pollution control. The course is also beneficial for a student with basic knowledge of EPA air pollution regulations and an interest in controlling NOx emissions from combustion sources. The reader will learn about the various control strategies and be able to evaluate the advantages and disadvantages of each as they apply to combustion sources and fuel types.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Background of Nitrogen Oxide compounds
  • Nitrogen Oxide effect on the environment
  • Nitrogen Oxide emissions from various fuels and combustion sources
  • Alternative control pollution prevention techniques and control technologies 
  • Effects of various fuels types
  • Support information for determining NOx action plans
Course Document

In this professional engineering CEU course, you need to review the EPA Publication "Nitrogen Oxides (NOx), Why and How They Are Controlled, {C}USEPA Clean Air Technology Center, EPA 456/F-99-006R".
