Advantages of HS-High specific surface Calcium Hydroxide
High surface area
High porosity
High purity

Efficient emission control
Sulfur dioxide -so2 -so3
Hydrochloric acid - HCl
Hydrofluoride HF
Big specific surface area provides more contact area for acid gas and hydrated lime translation.
With high pore volume, it can absorb more acid gas pollutants under the same amount of hydrated lime


• Low one-time investment
• Low equipment space occupation and low failure rate
• Improve the anti-corrosion performance, thermal efficiency, avoid complex cooling and heating, reduce the scaling phenomenon of the air preheater  and the minimum working temperature of the SCR system
• Improve SO3 removal rate, reduce blue plume, better protect activated carbon adsorbent and improve mercury removal efficiency
• Reduce the consumption of hydrated lime, the system load and solid waste
• Reduce boiler scaling and corrosion
• Good fluidity, easy to operate, reduce pipe scaling and accumulation
• High activity, reducing the impact of peak fluctuations
• Easy to maintain, eliminating the cleaning once a few weeks required by SDA semi dry method
• Sufficient system margin to cope with possible environmental upgrades and capacity improvements
HS-BS Ca(OH)2 is an efficient and easy-to-use calcium based adsorbent. 
It has the physical characteristics of high specific surface area and high pore volume, as well as efficient acid pollutant capture ability. 
The patented production process and surface modification technology make it excellent in capturing all acid pollutants, especially SO2. 
In addition, it is almost unnecessary to modify the original device.
HS-high specific calcium hydroxide can be used for additional investment or transformation.


Packing: 25 KGS, 50 KGS or 500 KGS/ bag, or according to the customer requirement.
