Simultaneous removal of NO<SUB>x</SUB> and SO<SUB>x</SUB> from the flue gas was performed under the gas feed rate from 50 to 80Nm<SUP>3</SUP>/hr using the slurry liquid of MgSO<SUB>3</SUB>-Mg (OH) <SUB>2</SUB>-e (II) edta system in a column packed with "SAN" packing.<BR>It was shown that the removal ratio of NO<SUB>x</SUB> exceed 90% for liquid-gas ratio above 30kg-liquid/kg-gas. More than 99% of SO<SUB>2</SUB> was removed. It was found that NO<SUB>x</SUB> removal ratio can be estimated by means of Porter's equation.<BR>As the results, deposition of solid particles in the apparatus does not occur when concentration of solid particles in the slurry liquid is in the range of 2-5%. Any increase in the initial concentration of MgSO<SUB>3</SUB> or Fe (II)-edta increases NO<SUB>x</SUB> absorption capacity of the absorbing liquid.<BR>NO<SUB>x</SUB> absorption capacity of the liquid did not increased so much at O<SUB>2</SUB> cocentration above 5% when the concentration of MgSO<SUB>3</SUB> and Fe (II)-edta in the liquid were increased.
