This report presents a cost analysis of Sulfuric Acid production from iron pyrate gases. In this process, iron pyrate gases are first treated for undesirable compounds removal and then, sulfur dioxide contained in the feed gas is converted to sulfur trioxide, which passes through double contact double absorption (DC/DA) process to generate sulfuric acid. This report was developed based essentially on the following reference(s): Keywords: Sulphuric Acid, Sulphur, Oleum, Fuming Sulfuric Acid, Exothermic Reaction, Catalytic Reaction, Smelter Operation, Metallurgical Off Gas, Roasting of Pyrites

This report presents a cost analysis of Sulfuric Acid production from sulfur The process examined is a conventional process comprising sulfur burning followed by a typical double-contact double absorption (DC/DA) process. In this process, sulfur dioxide is obtained by molten sulfur burning. Sulfur dioxide is converted to sulfur trioxide in a reactor. The sulfur trioxide-rich gaseous stream is absorbed in recirculating sulfuric acid. The absorption column offgas is sent to a further bed in the SO2 reactor for converting the remaining sulfur dioxide into sulfur trioxide, which is then absorbed in a second column with recirculating sulfuric acid. 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, Exothermic Reaction, Catalytic Reaction, Double-Contact Double Absorption, DC/DA

This report presents a cost analysis of Sulfuric Acid production from sulfur. The process examined is a conventional process comprising sulfur burning followed by catalytic conversion of sulfur dioxide to sulfur trioxide and single contact absorption process. In this process, sulfur is oxidized to sulfur dioxide and then converted by catalysis to sulfur trioxide, which is then absorbed in a recirculated stream with sulfuric acid. This report was developed based essentially on the following reference(s): Keywords: Sulphuric Acid, Sulphur, Oleum, Fuming Sulfuric Acid, Exothermic Reaction, Catalytic Reaction, Single-Contact
