UtiliMag® Magnesium Hydroxide and Magnesium Oxide:
Utility Emission Control Additive
Reduces SO3 and Opacity in Backend Treatment of Utility Boilers and Neutralizes Acidic WESP Effluent
For utilities and industrial companies using Selective Catalytic Reduction (SCR) systems to control backend boiler emissions, UtiliMag H, a high-purity magnesium hydroxide slurry and UtiliMag 40, a high-purity magnesium oxide (MgO) powder can be used to significantly reduce sulfur trioxide (SO3) generated by the boiler and SCR unit as well as opacity emissions and acid plumes related to SO3.
UtiliMag H can be added from the superheater section to the SCR outlet for SO3 control or to reduce opacity. UtiliMag H is also ideal for neutralizing acidic solutions generated from wet electrostatic precipitators (WESP).
UtiliMag 40 can be injected downstream of the SCR to the air heater inlet for effective SO3 removal, corrosion control and opacity treatment. Backend treatment with UtiliMag 40 can also reduce the formation of ammonium bisulfate in the air heater, resulting in less frequent, easier cleanup and elimination of corrosion.
In addition to UtiliMag powders and slurries, Martin Marietta offers testing equipment and dry powder injection systems for utility and industrial companies. For more information, please call 800-648-7400 (inside the U.S.) or +1-410-780-5500. Or, email us with your questions.
