DeNOx and DeSOx systems play a vital role in modern flue gas treatment technologies, especially in power generation, cement production, and industrial combustion processes. These systems are essential for reducing nitrogen oxides (NOx) and sulphur dioxide (SO₂) emissions from fossil fuel combustion, significantly contributing to global environmental protection efforts.

What is DeNOx Technology?

DeNOx (Selective Catalytic Reduction – SCR) is an advanced technology used to remove nitrogen oxides from exhaust gases by injecting a reducing agent—typically ammonia or urea—into the flue gas stream. The chemical reaction, facilitated by a catalyst, converts harmful NOx gases into harmless nitrogen (N₂) and water vapor (H₂O). This process is highly efficient and widely used in:

• Coal-fired power plants
• Gas turbines
• Waste-to-energy plants
• Oil refineries
• Cement and steel industries

What is DeSOx Technology?

DeSOx systems, primarily involving Flue Gas Desulfurization (FGD) units, are designed to eliminate sulphur dioxide (SO₂) from flue gases produced during the combustion of sulfur-containing fuels like coal and oil. A common method involves using a lime or limestone slurry that reacts with SO₂ to produce gypsum (CaSO₄), a marketable by-product.

Why Are DeNOx & DeSOx Systems Crucial?

When NOx and SO₂ gases are emitted into the atmosphere, they combine with water and oxygen to form nitric acid and sulphuric acid, which leads to acid rain—a major cause of soil degradation, forest damage, and aquatic ecosystem disruption. Implementing flue gas cleaning solutions like DeNOx and DeSOx systems is a critical step toward environmental sustainability and meeting emission regulations.
