What is Selective Catalytic Reduction (SCR)?

Selective Catalytic Reduction (SCR) is an advanced emission control technology designed to convert harmful nitrogen oxides (NOx) into harmless nitrogen (N2) and water vapor (H2O). This process significantly reduces NOx emissions, which are a major contributor to air pollution and acid rain. SCR systems are widely used in various industries, including power generation, chemical manufacturing, and transportation.

How does SCR work?

The SCR process involves injecting a reductant—either ammonia (NH₃) or urea (CO(NH₂)₂)—into the exhaust stream. As this mixture passes over a catalyst, it triggers a chemical reaction that breaks down NO_X into nitrogen and water.

Ammonia (NH₃)

Ammonia is directly injected into the exhaust stream where it reacts with NO_X in the presence of a catalyst to form nitrogen and water.

Urea (CO(NH₂)₂)

Urea is typically used as a safer alternative to ammonia. It decomposes into ammonia and carbon dioxide when heated, and the resulting ammonia then reacts with NO_X over the catalyst.

The process begins with the intake of exhaust gases containing nitrogen oxides (NO_X) into the SCR reactor.
A urea solution is added to the exhaust system before the SCR reactor.
In the SCR reactor, the exhaust gas passes through a catalyst bed; this catalyst material accelerates the chemical reactions required for NO_X reduction.
When the exhaust gas comes in contact with the catalyst bed and urea, a chemical reaction takes place. The nitrogen oxides (NO_X) in the exhaust react with urea (NH₂CONH₂) to form nitrogen (N₂) and water vapor (H₂O) according to the following reaction:

6NO_X + 4(NH₂CONH₂) → 5N₂ + 6H₂O + 2CO₂ + 2NH₃

As a result of this reaction, the harmful NO_X compounds are converted into harmless nitrogen gas, water vapor, carbon dioxide and ammonia. This reduction in NO_X emissions helps reduce air pollution and complies with environmental regulations.
The purified exhaust, which now contains significantly reduced NO_X emissions, leaves the SCR reactor and is emitted through the exhaust system.

Benefits of SCR Technology

SCR technology is highly efficient, capable of reducing NOx emissions by up to 90%. This makes it one of the most effective methods available for controlling emissions. Additionally, SCR systems are versatile and can be adapted to a wide range of industrial applications, helping companies not only comply with environmental standards but also improve overall operational efficiency.
