Nox Scrubber System
Industrial facilities and power plants located in North and South America dealing with nitrogen oxides (NOx) such as NO2 must consider the dangers of emitting pollutants into the atmosphere and determine an effective way to reduce nitrogen oxides. If left untreated, NOx emissions contribute to environmental smog and acid rain that pose a threat to layers of the ozone.
Businesses handling the combustion of fossil fuels can acquire the help of MACH Engineering for filtering nitrogen oxides that become dangerous for employees, system processes and those living in nearby communities.

What Are Nitrogen Oxides?
Signs of NOx Inhalation
- Irritation of eyes/skin
- Coughing
- Nausea
- Headache
- Difficulty breathing at site
Due to the health risks associated with NOx, a NOx wet scrubber system is critical not just for environmental protection, but also for worker protection.
NOx Wet Scrubbers
MACH Engineering NOx scrubber systems require vertical vessels for packing materials and filtration. Due to the nature of nitrogen oxide gases, nitrogen scrubbers require greater packing height, multiple scrubbing chemicals and sometimes multiple stages to achieve National Ambient Air Quality Standards (NAAQS). Because of this greater complexity, it is critical to work with an experienced team of engineers to select the appropriate packing materials and design an effective scrubbing process.
NOx Scrubbing Process
The first stage of nitrogen oxide scrubbing focuses on the oxidation of NO and NO2 through liquid solutions. The reduction process occurs in the second stage where nitrogen and oxygen molecules are separated. Depending on the physical and chemical properties of the gas streams containing oxides of nitrogen, some processes may require five or more stages to achieve the reactions needed to destroy the NOx constituents.
Our scrubbers are suitable for hot and cold phase systems depending on the type of industry. NOx scrubbers manage the following gas stream residuals for your business operations:
- Cl2
- HCl
- SO2
- Caustics
- And more
