With its signature rotten egg smell, hydrogen sulfide (H{sub 2}S) is not only odorous, but corrosive and toxic, too. It is produced naturally, by the anaerobic decomposition of sulfur-bearing materials, and synthetically, by a host of chemical process operations, including hydrogenation and hydrodesulfurization and coking. Many processes have been developed to convert H{sub 2}S to innocuous forms, such as elemental sulfur and sulfates. Selecting the best one depends on the overall composition and variability of the gas stream, the concentration of H{sub 2}S present, and the absolute quantity of H{sub 2}S to be removed. This article describes the advantages and disadvantages of seven H{sub 2}S removal systems. Described are: the Claus process, chemical oxidants, caustic scrubbers, adsorption, H{sub 2}S scavengers, amine absorption units, and liquid-phase oxidation systems.
