For significant reductions in NOx emissions

Nitrogen oxides, or NOx for short, is a group of pollutants that include nitrogen monoxide and nitrogen dioxide. They’re created when oxygen and nitrogen react at high temperatures, as in combustion processes within engines.

These NOx emissions contribute to air quality degradation and are a significant problem for the environment. They can lead to issues like acid rain, pollution of lakes and rivers (eutrophication), respiratory problems in humans, and the creation of harmful ground-level ozone and smog.

Most NOx emissions come from transportation sources, especially internal combustion engines in cars, trucks and ships. In recent years, with the advancement of cleaner technologies and catalytic converters, we've made significant progress in reducing these emissions by implementing stricter emission standards and regulations, focusing mainly on cars and trucks. These pollution control measures are in place as part of international protocols such as the Kyoto Agreement and other green initiatives.

DeNOx – NOx reduction with ammonia and urea

To meet these stricter NOx abatement requirements and to reduce environmental footprint, large energy producers such as power plants, waste incinerators, steel mills, fossil fuel operations, cement plants, and refineries are adopting advanced NOx remediation and emission control systems.

In markets where stringent air quality standards are enforced and very low NOx emissions are necessary, such as in marine applications, shipping and stationary installations, diesel engines use a post-combustion treatment process that involves adding a urea solution of 40%, or AdBlue into the exhaust stream.

A catalyst, known as Marine SCR (Selective Catalytic Reduction), aids in the chemical transformation and helps convert hydrolyzed urea into ammonia. This ammonia then reacts with NOx over the catalyst, transforming it into harmless nitrogen and water vapor, aiding in atmospheric protection.

This method can achieve a significant pollution abatement, resulting in up to 99% reduction in NOx emissions.

This use of Marine SCR technology allows us to achieve the IMO Tier III emissions limits. An alternative method, called SNCR (Selective Non-Catalytic Reduction), provides a means for NOx neutralization without the need for a catalyst.
