High Specific Surface Area Hydrated Lime is a highly reactive calcium-based desulfurizer developed based on advanced calcium modification technology, which can efficiently remove SO₂ and acidic gases such as HCl and HF in various flue gas desulfurization scenarios. As a core solution in the chemical environmental protection sector, it has become an indispensable technical support for enterprises to achieve ultra-low emissions and environmental compliance .

Main Classifications
To meet diverse needs of different industries and working conditions, our product covers two main series with customizable solutions available for special scenarios:
1. Standard Series: Stable specific surface area ≥50m²/g, suitable for most common flue gas desulfurization scenarios, featuring high reactivity and stable performance .
2. Customized Series: Specific surface area ranging from 40-100m²/g, tailored for extreme working conditions such as high-temperature flue gas or high-concentration SO₂ environments .
Design Philosophy
Our product adheres to the core design philosophy of high reactivity, low energy consumption, and resource recycling, fully considering harsh industrial working conditions and strictly following full-life-cycle reliability design standards to provide customers with stable, low-maintenance, and cost-effective technical solutions .
Technical Principles
The core working principle of High Specific Surface Area Hydrated Lime is based on calcium-based chemical reactions. The complete implementation chain is as follows:
1. Input: The high-reactivity hydrated lime particles are injected into the flue gas stream, making full contact with acidic gases such as SO₂ .
2. Reaction: The porous structure of the product provides a large reaction area, enabling rapid and full reaction with acidic gases to form stable by-products such as calcium sulfate .
3. Output: The reacted by-products are collected, which can be recycled as building materials or soil conditioners, achieving resource utilization .
Core Architecture & Innovative Design
We have optimized the product structure with two key innovative modules:
1. High-Porosity Particle Module: The large pore structure increases the specific surface area, significantly improving reaction speed and efficiency compared to traditional hydrated lime .
2. Precision Formula Module: The optimized calcium-based formula ensures stable reactivity across a wide temperature range, avoiding performance attenuation during long-term continuous operation .
Comparison with Traditional Solutions
Compared to traditional desulfurization materials such as sodium bicarbonate, our product achieves core breakthroughs:
1. Lower Consumption: Calcium-sulfur ratio is controlled at 1.2-1.5, reducing desulfurizer consumption by 20%-40% and cutting operational costs .
2. Recyclable By-Products: The unreacted Ca(OH)₂ in by-products accounts for ≤5%, with high-purity calcium sulfate that can be recycled, eliminating secondary pollution .
