Embodiments of the disclosure include systems and processes for the recovery of sulfur dioxide (SO.sub.2) from tail gas of sulfur recovery plant or from flue gas of a power plant, such as flue gas originating from an H.sub.2S-containing fuel gas for a gas turbine. SO.sub.2-containing gas is dissolved in chilled water and produce SO.sub.2-containing chilled water. The SO.sub.2-containing chilled is contacted with H.sub.2S-containing gas to aqueously react H.sub.2S and SO.sub.2 and form elemental sulfur. A water stream with the entrained sulfur is routed to a solid-liquid separate, and separated sulfur may be processed or disposed of. The water is recycled and chilled for use in the reaction. Embodiments also include the generation of sulfur dioxide (SO.sub.2) from produced sulfur instead of using tail gas or flue gas.

A contact process, sulfuric acid system and method are disclosed for producing sulphuric acid with improved operating efficiency in humid environments. The system comprises a pre-drying absorber for pre-drying humid air with weak sulfuric acid. Weak sulfuric acid from the pre-drying absorber is provided to a subsystem comprising two sulfur trioxide absorbers and a heat exchanger for the recovery of heat via steam production. This arrangement allows for a marked increase in steam production (i.e. energy efficiency). In a separate improvement, the emission apparatus for the system can be simplified using a peroxide tail gas scrubber comprising upper and lower scrubber sections in which the upper scrubber section consists essentially of tray type scrubbers.
