hydrogen peroxide air purification

Cleaner air through fewer exhaust gases

Air purification

As an effective oxidant, hydrogen peroxide can be used to increase air quality in industrial plants. Air pollution from exhaust gases can be harmful to the ecosystem, the climate, buildings and the health of people, animals and plants.

HOW DOES HYDROGEN PEROXIDE INCREASE AIR QUALITY?

At the end of the last century, acid rain was a major environmental problem in many developed countries. Although the air in Europe has become much cleaner in the meantime, industry and traffic cause the emission of the environmentally harmful gases carbon monoxide and nitrogen dioxide — and even particulate matter — mainly through the combustion of fossil raw materials such as coal and crude oil. 

Since 2020, the reduction of national emissions of air pollutants has been regulated by an E.U. directive. The use of hydrogen peroxide helps to meet emission reduction targets for sulfur dioxide (SO2), which is present in exhaust gases. In this way, limit values can be significantly reduced.

Removal of mercaptans, hydrogen sulfide (H2S), and sulfur dioxide (SO2) from wastewater or exhaust gases is achieved by using a wet scrubber with hydrogen peroxide. It is also used to reduce toxicity and odors in paper mills, rendering plants, and metal smelting, and in pharmaceutical, pesticide, chemical, or petrochemical plants.

Hydrogen peroxide is used in various technological processes to reduce environmental pollution caused by exhaust gases. For example, nitrogen dioxide and nitrous oxide emissions can be greatly reduced in steel industry production processes that use nitric acid in a pickling process. Nitrogen dioxide is also produced to a lesser extent in the paper industry.
