NOx Scrubbers FAQ

NOx Scrubbers – Frequently Asked Questions

1. What are NOx Scrubbers?

NOx scrubbers, also known as flue gas desulfurization systems, are pollution control devices used to remove nitrogen oxides (NOx) from industrial flue gases emitted by power plants, boilers, and other industrial facilities. These scrubbers utilize various techniques to convert harmful NOx compounds into less harmful substances through chemical reactions.

2. Why is reducing NOx emissions important?

Reducing NOx emissions is crucial to protecting the environment and human health. High levels of NOx contribute to the formation of smog, acid rain, and ground-level ozone, which can lead to respiratory issues, cardiovascular problems, and other health hazards. By installing NOx scrubbers, industries can significantly reduce their impact on air quality.

3. How do NOx scrubbers work?

NOx scrubbers work by introducing a scrubbing medium, typically a liquid solution, to the flue gas stream.
