SO2 emissions has begun to cause serious problems in industrialized countries. Today, various methods are used for removal of SO2 gas. SO2 gas is an important raw material for production of sulfuric acid. However, SO2 content of flue gas must be over 6% to produce sulfuric acid commercially. Flue gases, which don't have enough amount of SO2 to produce sulfuric acid commercially are harmful to the environment and human health and they must be filtered. In this study, calcined dolomite was used to remove SO2 in flue gas which doesn't have enough SO2 to produce sulfuric acid but have high emission values. Pyrite was used as SO2 source and SO2 removal efficiency of dolomite was determined for different experimental parameters. SO2 capturing system was thermodynamically modeled and SO2 capturing efficiency was determined as 77.81% in the experiments.
