Semi-dry ammonium desulfurization technology is proposed to meet the requirements of Directive 2010/75/EU on reducing sulfur dioxide emissions and obtaining dry product - ammonium sulfate. The peculiarity of this technology is the presence of a gas-phase reaction of sulfur dioxide with ammonia along with the absorption of SO2 in drops of ammonia water. The efficiency of the absorption of sulfur dioxide by gaseous ammonia (up to 90%) has been experimentally proved, subject to the presence of water vapor in the gas, the volume concentration of which should exceed the volume concentration of ammonia.
