Introduction
Introduction to Calcium Hydroxide for Flue Gas Treatment
Calcium hydroxide, with the chemical formula Ca(OH)₂, is a versatile inorganic compound widely recognized for its applications in various industries. In recent years, it has gained significant attention for its role in flue gas treatment, particularly in reducing harmful emissions from industrial processes. This product overview highlights the use of calcium hydroxide in flue gas treatment, its benefits, and why it is a preferred choice for air pollution control.
Key Features of Calcium Hydroxide for Flue Gas Treatment
High Purity: ≥95% purity, ensuring effective and reliable performance.
Eco-Friendly: Complies with global safety standards, including REACH certification.
Cost-Effective: Reduces operational costs by efficiently neutralizing acidic gases.
Versatile: Suitable for a wide range of industrial applications, including power plants, cement factories, and waste incineration facilities.
How Calcium Hydroxide Works in Flue Gas Treatment
Calcium hydroxide is primarily used to remove acidic pollutants such as sulfur dioxide (SO₂), hydrogen chloride (HCl), and hydrogen fluoride (HF) from flue gases. Here’s how it works:
- Neutralization of Acidic Gases
Calcium hydroxide reacts with acidic gases to form neutral compounds, effectively reducing air pollution.
Example Reaction:
Ca(OH)₂ + SO₂ → CaSO₃ + H₂O - Formation of Stable Byproducts
The reaction produces non-hazardous byproducts like calcium sulfite (CaSO₃) and calcium sulfate (CaSO₄), which can be safely disposed of or reused. - Improved Air Quality
By removing harmful gases, calcium hydroxide helps industries comply with environmental regulations and improve air quality.
Advantages of Using Calcium Hydroxide for Flue Gas Treatment
High Efficiency: Effectively removes up to 99% of acidic gases.
Easy to Handle: Available in powder form, making it easy to store and transport.
Sustainable: Reduces the environmental impact of industrial emissions.
Cost Savings: Lowers the need for expensive air pollution control equipment.
Applications in Flue Gas Treatment
- Power Plants: Reduces sulfur dioxide emissions from coal-fired power plants.
- Cement Industry: Controls acidic gases released during cement production.
- Waste Incineration: Neutralizes harmful gases from waste-to-energy plants.
- Chemical Manufacturing: Minimizes emissions from chemical processes.
Transportation and Storage
Packaging: 25kg bags with moisture-proof lining.
Storage: Store in a cool, dry place at 5-30°C with humidity ≤60%.
Safety: Avoid contact with acidic substances and follow MSDS guidelines.
