FIELD: chemistry.
SUBSTANCE: aqueous solution of H2O2 is dispersed in waste gas with temperature of 30-150°C, containing 0.001-1 volume % of SO2. Then obtained H2SO4 is removed from waste gas by aerosol filter or humid electrostatic separator. Waste gas is cooled down by evaporation of water from H2O2 solution.
EFFECT: enhanced separation efficiency.
