The removal of sulfur dioxide from glass fume discharging is a very important technology in light of burning coal for electricity generation. It takes shape as part of desulfurization; that is when sulfur dioxide produced by burning fossil fuels with oxygen gets absorbed into a liquid such as water and converted into sulfuric acid before being finally expelled into the atmosphere. Through the use of limestone or lime slurries to absorb the sulfur dioxide, we have created a chemical reaction that results in solid gypsum. The ashes can be sold as byproducts at this point in time. Typically the process uses absorber towers, slurry preparation systems, gypsum dewatering systems and water treatment facilities. Applications for flue gas desulfurization are found in coal-fired power plants as well as cement kilns and other industrial processes that release a high content of sulfur dioxide.
