Simultaneous removal of low-concentration nox and sox

PURPOSE: To remove low-concentration NOx and SOx contained in an exhaust gas for ventilation such as from a road tunnel efficiently simultaneously. CONSTITUTION: The method for removing low-concentration NOx and SOx simultaneously is to desulfurize an exhaust gas in a wet state in a moisture adjustment column 1 installed in the upstream of a rotary adsorption denitration device 2, and denitrate the exhaust gas in a rotary adsorption denitration device 2.
