Abstract

A process for removal of SO2 in off-gases having a temperature of 30-150~C a nd containing 0.001-1 vol% SO2 in which the SO2 is oxidised to H2 SO4 by sprayi ng an aqueous solution of H2O2 into the off-gas upstream of an aerosol filter removing the produced sulphuric acid from the off-gas.

Claims (3)

1. A process for removal of SO2 in off-gases having a temperature of 30-150°C and containing 0.001-1 vol% SO2 in which the SO2 is oxidised to H2SO4 by spraying an aqueous solution of H2O2 into the off-gas upstream of an aerosol filter removing the produced sulphuric acid from the off-gas.
2. A process as in claim 1, in which the off-gas is cooled by evaporation of the water comprised in the solu-tion being sprayed into the off-gas upstream of the filter.
3. A process as in claim 1, in which a wet electro-static separator us used in place of an aerosol filter.
