Study to Ascertain the Efficacy of the Bag Filters Attached to Various Locations at a Calcining Plant

This study investigates the efficacy of bag filters installed at various locations within a calcining plant situated in Paradeep, Odisha, India. The plant processes raw petroleum coke into calcined petroleum coke, generating significant amounts of particulate matter and gaseous emissions. The research focuses on assessing ambient air quality inside the plant premises and evaluating the performance of the bag filters in reducing particulate and gaseous pollutants. Measurements of PM2.5, PM10, SOx, and NOx were taken using the EVM-7 equipment under operating and non-operating conditions of the bag filters. Results indicated substantial reductions in particulate concentrations when bag filters were in operation, although some levels remained above standard limits. The study highlights the importance of continuous operation and maintenance of pollution control equipment, proper handling of materials, and enhanced housekeeping practices to mitigate indoor air pollution and ensure workplace safety.
