Book excerpt: This report presents a cost analysis of Sulfuric Acid production from hydrogen sulfide gases. The process examined is Wet gas Sulfuric Acid (WSA) process similar to the one owned by Haldor Topsoe. In this process, hydrogen sulfide contained in the feed gas is burned, forming to sulfur dioxide and water. Sulfur dioxide is converted to sulfur trioxide and then cooled to a teperature where it reacts with water in the gas phase and forms sulfuric acid, which is then condensed and concentrated to about 98 wt%. This report was developed based essentially on the following reference(s): "Sulfuric Acid and Sulfur Trioxide", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Sulphuric Acid, Sulphur, Oleum, Fuming Sulfuric Acid, hydrogen sulfide gases, WSA
