Abstract
A process of producing sulfuric acid from feed gases containing 0.1-30% SO. The process produces concentrated sulfuric acid from a feed gas containing 0.1 vol % to 30 vol % SO, in particular a strong feed gas containing 6 vol % to 30 vol % SO, that enables the gas entering the final wet condensing stage to have an acid dew point of below 260° C., while at the same time achieving current requirements of acid mist emissions of about 20 ppmv without resorting to substantial air dilution of the strong feed gas.
