The pilot program showed that % SO2 removal can be achieved for a stoichiometric ratio of 1 to 2 by dry injection of the silica enhanced lime when using a duct + baghouse configuration, or when using a duct + cyclone configuration including recycle.

Application of DSI for flue gas de-sulfurization (FGD) in high temperature range of –°C (upper-furnace region) involves injection of dry calcium-based sorbents in the above-the-flame. A significant emerging variation of duct sorbent injection is the ADVACATE (Advanced Silicate) process offered by ABB-Fläkt. The first commercial systems are expected to achieve 90% SO 2 removal with a Ca/S ratio of less than with costs about 50% of wet FGD. SO 2 removal efficiencies up to 99% have been reported on a pilot plant, including the effects of upstream furnace sorbent injection. The Dustex TM Dry Sorbent Injection (DSI) System provides a cost-effective solution for the reduction of SOx (SO 2, SO 3), and HCl from boiler flue gases.. Dry Sorbent Injection Systems involve the injection of a dry sorbent into the flue gas ductwork following the boiler to reduce concentrations of acid gases SO 2, HCl and HF which are regulated to prevent acid rain. Dry Sorbent Injection (DSI) Proven low captial cost solution to meeting your SO2, SO3 & HCI emissons performance There are a number of technologies available to help industrial boiler operators, fossil fueled electrical generation facilities, and biomass plants meet recently established and .
modeling for the injection grid design, on-site testing to validate sorbent type and injection rate, and proactive lab testing and evaluation of the effects on existing ash handling systems. UCC offers the expertise, confidence and single point accountability our customers expect in dry sorbent injection . Dry Sorbent Injection Systems Dry Sorbent Injection Systems As coal fired power plants faced increased environmental regulations amid commercial viability concerns, a growing number of plants have adopted Dry Sorbent Injection (DSI) as an answer to compliance and efficiency requirements. Fortunately, or unfortunately, there are as many sorbents. Name of Technology: Flue Gas Desulfurization (FGD) - Wet, removal for dry sorbent injection systems range from °C to °C (°F to °F). Optimal temperatures for SO Proprietary sorbents with reactivity-enhancing additives provide control efficiencies greater t han 95% but are very costly. Electrical utilities. Chang, J. C. S. and C.
