Hydrated lime (Ca(OH)₂) is one of the most effective materials used today to combat air pollution from industrial activities. Among its many applications, its role in flue gas desulfurization (FGD) stands out as a critical solution to reduce sulfur dioxide (SO₂) emissions — a major contributor to acid rain, respiratory problems, and environmental damage.

Why Control SO₂ Emissions?

Sulfur dioxide is a major byproduct of burning fossil fuels such as coal and oil, especially in power plants, cement kilns, and metallurgical processes. Once released into the atmosphere, SO₂ contributes to acid rain, which damages ecosystems, corrodes infrastructure, and poses serious risks to human health. With governments worldwide tightening emission standards, industries need reliable solutions — and hydrated lime is proving to be one of the most efficient.

Hydrated Lime in Action

Ca(OH)₂ has become one of the most effective materials for flue gas desulfurization (FGD). When injected into flue gases, it reacts chemically with sulfur dioxide, binding the pollutant and transforming it into a stable compound that can be safely managed.

Benefits of Hydrated lime for Industry and the Environment

Significant SO₂ reduction → Lower air pollution and compliance with environmental standards.
Cost-effective solution → Readily available and easy to handle compared to alternative methods.
Flexible application → Suitable for power plants, cement production, steelmaking, and other heavy industries.

Real-World Impact

Many large-scale power plants and cement factories worldwide have already adopted slaked lime-based FGD systems. The results are clear: dramatic reductions in SO₂ emissions, improved compliance with international environmental standards. Moreover, it leads to more positive public image for companies investing in cleaner technologies.

Building a Sustainable Future

Hydrated lime is more than just a simple chemical compound — it is a reliable partner in the global effort to combat air pollution. By integrating it into emission control systems, industries can protect local communities, safeguard natural ecosystems, and ensure compliance with environmental regulations, all while maintaining operational efficiency.
