Calcium based reagents are an effective means to control a variety of flue gas pollutants including SO2, SO3, HCL and HF. Calcium based sorbents can also play a role in the control of Arsenic (As) and Mercury (Hg).
Lime, hydrated lime and limestone are effective reagents for controlling SO2 and SO3 in electric utilities as well as a variety of industrial applications. Hydrated Lime has proven to be an effective tool in mitigating SO3.
Lime and hydrated lime products can be effective in controlling HCl and HF. And as a result lime scrubbing is used to control HCl in industrial applications including industrial incinerators and waste to energy facilities.
Calcium products such as calcium carbonate and calcium oxide can be used to address Arsenic concerns. Arsenic can negatively impact the SCR operation at electric utilities. Calcium carbonate products such as Calcarb R1 and Calcarb R2 are potentially effective solutions for As foulling situations.
Hydrated lime and other calcium products are being investigated as additives to help control mercury emissions.
Mississippi Lime’s portfolio of Standard Quicklime, Standard Hydrated Lime, Liquid Calcium Hydroxide and Calcium Carbonate product families provide a broad variety of tools to address flue gas pollutant situations.
