A process plant for the production of sulfuric acid from a gas comprising H2S comprises an alkaline absorber for con- tacting a gas comprising H2S with a liquid ammonia absorbent solution and a dissolved material, that is catalytically active in the oxidation of H2S to elemental sulfur, separation means for producing an absorber liquid free of elemental sulfur to be returned to the absorber and a stream of elemental sulfur and purged absorber liquid to be introduced into an incinerator, air-free nozzles for receiving and atomizing the elemental sulfur and purged absorber liquid into an incinerator, means for cooling, a particulate removal device, a sulfur dioxide converter for oxidation of SO2 to SO3, and means for the provision of concentrated sulfuric acid. |
