Sodimate technology can help coal-fired and waste-to-energy plants meet stringent EPA regulations regarding flue gas emissions of acidic gases and heavy metal pollutants. Sodimate’s dry sorbent injection flue gas cleaning systems can be used with dry chemicals such as lime, trona, urea, powdered activated carbon (PAC), and soda ash.
A primary goal of flue gas treatment is sulphur dioxide removal along with removal of of hydrogen chloride (HCl), mercury (Hg) and other heavy metal particles. Sulfur dioxide control is commonly achieved using calcium hydroxide injection, and mercury is commonly removed with PAC injection. In each of these processes when the dry chemical is exposed to the acidic gases, a dry particulate material is created which can then be separated and removed.
