High Specific Surface Calcium Hydroxide Desulfurizer refers to calcium hydroxide with an exceptionally large specific surface area, typically exceeding 50 m²/g.
The MS-HAD series high-efficiency desulfurizer is a a new product developed by us with full independent intellectual property rights. The BET surface area of the product is 50-100m2/g, reaching the international leading level. It is widely used for flue gas desulfurization in industries such as steel, coking, industrial silicon, sodium silicate, photovoltaics, new energy, lithium batteries, carbon materials, cement, glass, ceramics, waste-to-energy, and refractory materials.
Core Features & Benefits：
1. Superior Adsorption Capacity
Efficiency: Removes >95% of sulfur dioxide (SO₂) from flue gas, with broad adaptability to gas temperatures (0-430℃), minimal temperature drop, and excellent fluidity.
2. Low construction investment and environmental protection: no water consumption, no hazardous waste generation, no wastewater discharge, no carbon emissions, and by-products can be recycled. It can replace some high-cost adsorbents (such as activated carbon), reducing environmental governance costs; as an alkaline material, it is naturally non-toxic, and the desulfurization product (CaSO₃) is harmless to the environment.
Wide Application:
Demonstrates significant advantages in flue gas desulfurization across industries including environmental protection, new materials, steel, coking, industrial silicon production, sodium silicate manufacturing, photovoltaics, lithium battery production, cement, and waste-to-energy plants, positioning it as a high-efficiency functional material.
SO2 removal from flue gas in ceramic plants, steel plants, waste-to-energy plants, industrial silicon facilities, glass factories, blue carbon plants, coking plants, and lithium processing plants.

High-surface-area calcium hydroxide, with its unique pore structure, ensures that HCl and SO₂ emissions in flue gas are significantly below the stringent standard of 10mg/m³. Its highly efficient chemical reaction mechanisms—such as the reaction between Ca(OH)₂ and SO₂ to form CaSO₃ and H₂O, as well as the reaction with HCl to produce CaCl₂ and H₂O—can be completed in an extremely short time, with a utilization rate exceeding 85%. Moreover, its superior flowability effectively prevents pipeline clogging and other issues in practical applications, further enhancing operational convenience and safety.

With advancements in dry desulfurization technology, dry methods with significant advantages are gradually replacing wet desulfurization. Many existing desulfurization towers in the market are approaching maintenance or replacement cycles due to corrosion and other factors. Replacing these towers with dry desulfurization processes offers lower investment and operational costs.
Dry desulfurization utilizes highly efficient calcium-based desulfurizers, which are strongly alkaline inorganic non-metallic powders. These agents excel in gas adsorption, reactivity, fluidity, and reaction speed. They also feature broad temperature adaptability (0–430°C), low construction costs, minimal carbon emissions, and easily recyclable by-products, making them highly promising for widespread applications.
This product has been extensively applied in industries such as lime kilns, coking, steel, metallurgy, chemicals, mineral processing, and building materials under complex flue gas conditions. It achieves a desulfurization efficiency of over 97%.
