The majority of sulfur recovered via natural gas sweetening is obtained from some form of the Claus process. These are dry-bed catalytic processes operating on the acid-gas stream from the regeneration step of a liquid-absorption process such as an amine unit. The direct-oxidation process is similar but is used for recovering sulfur from acid-gas streams with small HD2US concentrations. The Claus process was developed in 1890 and involved the vapor oxidation of HD2US to sulfur in the presence of a catalyst such as bauxite. The reaction was characterized by the evolution of large quantities of heat. As a result of German development work, 2 basic schemes are used today. These are the once-through and split-stream processes. Variations of each exist to handle differences in acid- gas quantity, composition, and sulfur-recovery level.
