An Introduction to Sulfur and Nitrogen Oxides Control in Air Pollution

COURSE NO: C03-068
An Introduction to Sulfur and Nitrogen Oxides Control in Air Pollution
Course Highlights

This online engineering PDH course provides an introduction to nitrogen and sulfur oxides formation in boiler plant and incinerator emissions.


All fossil fuels contain sulfur compounds, usually less than 8 percent of the fuel content by weight. During combustion, fuel-bound sulfur is converted to sulfur oxides in much the same way as carbon is oxidized to CO2. Sulfur dioxide (SO2) and sulfur trioxide (SO3) are the predominant sulfur oxides formed. All fossil fuel burning processes also produce NOx. The principle oxides formed are nitric oxide (NO) which represents 90-95 percent (%) of the NOx formed and nitrogen dioxide (NOx) which represents most of the remaining nitrogen oxides.


This 3 PDH online course is applicable to environmental and mechanical engineers as well as boiler plant managers who are interested in learning about sulfur and nitrogen oxides control in air pollution.
Learning Objectives

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

  • Familiarizing with formation of sulfur oxides
  • Learning about procedures to minimize SOX emissions
  • Understanding nitrogen oxides control and reduction techniques
  • Exploring available methods for reducing SOX emissions
