What is a denox scrubber system?
A DeNOx scrubber is a type of air pollution control device specifically designed to remove nitrogen oxides (NOx) from exhaust gases. These nitrogen oxides are typically produced during combustion processes, particularly at high temperatures, in industries like power generation, manufacturing, and vehicle emissions. DeNOx scrubbers are crucial in reducing the environmental and health impacts of these pollutants.
How does it work?
The DeNOx scrubber implements the use of liquid hydrogen peroxide to oxidize NOx species. For this treatment, it is used a vertical scrubber in which contaminated air is introduced at the base of the tower, and it moves upward through the tower filled with packing material.
The hydrogen peroxide-containing scrubbing medium is continuously introduced from the top of the tower, and it flows in countercurrent with the air through the packing material. The purified air exits at the top of the tower, and it can either be safely released into the atmosphere or directed to the next step of the process.
The waste containing the pollutants is collected at the bottom of the tower and it requires further treatment or specific disposal.
The scrubber system is equipped with automated controls that monitor and regulate parameters such as flow rates of air and scrubbing medium, pH levels, and pressure differentials.
Which problem can sort it out?
DeNOx scrubbers, designed to reduce nitrogen oxides (NOx) emissions, are particularly crucial in industries where combustion processes are prevalent and generate significant NOx emissions.
