SOLVAir®s efficient air pollution solutions for the cement industry

With cement manufacturers becoming more environmentally friendly and switching to alternative fuels such as waste and industrial residues, HCl and SO2 in flue gas emissions need to be treated differently. By injecting a sodium-based dry sorbent into the flue gases right before bag filters, the pollutants can be removed with the minimum amount of sorbent, with residues formed at minimum cost per ton of clinker produced. The sodium-based sorbent addition does not significantly affect the alkali standard limits in the clinker, even if cement kiln dust is wholly recirculated as part of the raw feed…a most efficient way of complying with emissions limits!

Cement plant brings down SO2 and HCl emissions!

At a North American cement plant, a solution to provide the most efficient acid gas removal from flue gases while consuming less sorbent was implemented by SOLVAir®, generating less residue and reducing related logistics costs. Results? Over 97% mitigation of SO2 and HCl emissions! Find out more here!

Low capital cost waste incineration for a plant’s small footprint
When waste incinerators have to deal with HCl, SO2 and SO3 emissions without space for large air pollution control systems, low capital cost sodium sorbent DSI makes sense for a small footprint. DSI can be effective for sorbent injection as “trim” at the end of an existing system, and provides a flexible technology to cut pollutants during peaks.  SOLVAir can help identify the optimal injection strategy depending on system configuration and reduction targets. Click here for more information.

Targeted Pollutants
For over 30 years, SOLVAir® S150 and S200 Trona,  and S300 and S350 Sodium Bicarbonate have helped eliminate or control SO2 and SO3 (SOx), HCl and mercury (Hg) in acid gas emissions. Our understanding of regulatory compliance, expertise in Dry Sorbent Injection, and our ongoing independent field tests help customers meet their compliance goals, both effectively and cost-effectively.

Industries Served
SOLVAir’s trona or sodium bicarbonate in a Dry Sorbent Injection system has effectively helped reduce or eliminate SO2, SO3 and HCl in flue gases in markets including coal fired power plants, cement, glass, biomass, waste-to-energy, industrial boilers and waste incinerators.

SOLVAir® Products
SOLVAir® Products, including S150 and S200 Trona, and S300 and S350 Sodium Bicarbonate, are the direct approach for air pollution control. Whether in wet or dry scrubbers or in Dry Sorbent Injection (DSI) systems, these are the products your plant needs to clear the air.

The Responsible Care® Initiative
We are committed to sustainable development through the Responsible Care initiative, a policy adhered to by all Solvay companies, in every country in which Solvay has a presence. The Responsible Care initiative underscores our focus on continuous improvement in the health, safety and environment of our planet.
