“…In the industrial sectors concerned with fossil fuels, mining and the chemical processing industry, the major threats to human life are the emission of the Sulphur and nitrogen-based toxic content gases into the environment [1]. When these gases come into the atmosphere and get the oxidation process with the pure oxygen compounds it leads to the formation of oxides of nitrogen and Sulphur compounds causing acid rain and greenhouse effects to the surrounding circumstances [2,3].…”

This paper aims to explore experimental studies on the NOx removal process by using pilot plant packed column experimental hardware. Physical modeling based on chemical absorption equations is used to estimate the diameter concerning the height and L/G ratio. Hydrogen peroxide is used as the additive for achieving high NOx removal efficiency. The absorbent entering into the packed column has been controlled by varying its flow rate through the fractional order controller. The FOCDM-PIλDµ controller tuning parameters such as KP, τI, τD are determined using CDM (Coefficient Diagram Method) PID control strategy and the additional parameters of FOCDM-PIλDµ controller such as λ and µ are determined based on the PSO algorithm. The comparative analysis is performed with classical controllers like ZN-PID along with the CDM-PID controllers.
