Experimental Investigation on NOx Emission Control Using Pilot Plant Control System

This paper is mainly focuses on design and experimental investigation on NOx removal process and to optimize the packed column parameters and the absorbent used to obtain high removal efficiency. The experiment is held with different absorbents such as water, HNO3 andH2O2. Hence the result obtained is about the high removal efficiency above 98% by adding 0.1M of Hydrogen Peroxide. From the analysis the packing material used is optimized as Intolax ceramic saddles with 10mm diameter, liquid (absorbent) flow rate of 5 lph, gas flow rate of 1m3/hr and the packing height of 0.70m are optimized for the lab scale analysis of pilot plant based on the performance of packed column for improving NOx absorption rate.
