Emission Control Diesel Power Plant for Reducing Oxides of Nitrogen through Selective Catalytic Reduction Method using Ammonia

Background/Objectives: The major pollutant that comes out from engine exhaust of Diesel Power Plant (DPP) is Nitrogen Oxide (NO_x)as well as Sulphur oxides (SO_x). Since NOx concentration level is higher it affects our environment to great extent. Our main objective of our project is to reduce NO_x concentration level to lower rate of parts per million (ppm). Methods/Statistical Analysis: The NO_x concentration level is higher in DPP as they didn’t install any NO_x control methods. We suggested using Selective Catalytic Reduction (SCR) method for controlling NO_x emission. Ammonia (NH₃) is making use of reagent in SCR technique and it is inject to the exhaust stream. Findings: NH₃ reacts with NO_x present in the exhaust and it is converted into Nitrogen (N₂) and water (H₂O). It is proposed that, if SCR system is installed in Diesel Power Plant, NOx concentration level is expected to reduce from 1100 ppm to 132 ppm. Application/Improvements: If The proposed system is implemented successfully in the power plant, then NOx concentration level could be reduced to approximately 132ppm (<2 g / kWh).
