SCR Systems

Indure has rich experience and know how having supplied ash handling systems for over 78,000 MW including systems for large units of size 800 MW. In order to offer comprehensive solution for denitrification based on SCR (Selective Catalytic Reduction) technology, Indure along with its partner Termokimik Corporation, Italy is well positioned and equipped to offer state of the art SCR systems to clients in India.

Active since 1938, Termokimik Corporation is an engineering contracting and construction company from Italy specializing in the design, manufacturing, supply and installation of a wide range of processes and turn-key industrial plants in the field of environment control technologies. With more than 28,000 MW of successfully realized installations all over the world, Termokimik is a leading supplier of SCR systems to reduce emissions of Nitrogen Oxides.

Denitrification by SCR technology

A reduction in the amount of nitrogen oxides being discharged into the atmosphere as combustion gases are emitted from power and industrial plants has become an important goal to minimize environmental pollution. The most efficient secondary technique for removing such Nitrogen Oxides from the burning of fuels such as coal, oil and natural gas, municipal and hazardous waste, is their conversion into inert nitrogen gas by reaction with a reducing reagent, using the Selective Catalytic Reduction (SCR) technology through which reduction efficiencies of 90% and more can be achieved through SCR process which mainly consists of a reducing agent upstrem of one or more catalyst layers.

Catalysts may be produced in different configurations but for SCR DeNOx plants, honeycomb and plate-type catalysts are mainly used. Oxides of Vanadium, Titanium and Tungsten (V2O5, TiO2, and WO3) are widely used for ceramic monolith and composite SCR catalysts. Titanium oxides typically constitute the support while Vanadium is the active principle. Operating temperature ranges from 180 °C up to 500 °C, depending on several parameters like type of fuel, flue gascomposition and configuration of upstream flue gas treatment. The catalyst is installed inside a Reactor that can be positioned in different alternative places along the flue gas treatment line. Two configurations are most commonly used the “High Dust System“ upstream the flue gas treatment and the “Tail End System“ (which operates with cleaned gas). The best solution is obtained by taking into account process parameters, layout considerations and economical evaluations.
