Flue gas treatment (FGT) has become a focus of electric utilities and industrial operations due to new air quality standards. As companies seek to comply with air quality regulations and to use more economical fuel sources the need to effective flue gas treatment options has increased.
A variety of calcium based materials are effective reagents for treating acidic air emissions. The primary categories of calcium reagents used in FGT applications are:
• Calcium hydroxide (hydrated lime)
• Calcium oxide (quicklime)
• Calcium carbonate (limestone)
These reagents have differing characteristics and can be effectively employed at different points in the process. Calcium based reagents are effective at removing acid gases including:
• SO2 - Sulfur dioxide
• SO3 - Sulfur trioxide
• H2SO4 - Sulfuric acid
• HCl - Hydrogen chloride
• HF - Hydrogen fluoride
The largest application area of calcium based reagents is for SO2 treatment and SO3 treatment, however, the use is growing in Multi-pollutant removal situations. Mississippi Lime has a wide range of calcium based reagent products and the required expertise to support you applications needs.
