In 1883, the Claus process for producing sulfur from hydrogen sulfide through partial combustion over an iron oxide catalyst was patented. It enjoyed limited success as a method for producing sulfur over the following 50 years, despite a number of process improvements. Its primary use arose with the need for a means to remove the sour component of sour gas for processing reasons and for environmental compatibility.

With the aid of chemical equations, describe the Claus process for the production of sulfur from hydrogen sulfide. 

In multiple-tube boilers (usually horizontal) the fire may be on the tube side. As long as the fire tubes are kept submerged in water, the tubes do not overheat. Boilers of this type are widely used in the regeneration of spent sulfuric acid, and in the production of elemental sulfur from hydrogen sulfide. 

The practical importance of the higher sulfanes relates to their formation in sour-gas wells from sulfur and hydrogen sulfide under pressure and their subsequent decomposition which causes well plugging (134). The formation of high sulfanes in the recovery of sulfur by the Claus process also may lead to persistance of traces of hydrogen sulfide in the sulfur thus produced (100). Quantitative deteanination of H2S and H2S in Claus process sulfur requires the use of a catalyst, eg, PbS, to accelerate the breakdown of H2S (135).

MS As are recirculated. The stripped acid gases are fed to a Claus unit" where elemental sulfur is recovered from hydrogen sulfide. In view of air pollution control regulations, the tail gases leaving the Claus unit, R, should be treated for partial removal of the unconverted hydrogen sulfide. Table 3.10 summarizes the stream data. 

In 1875 Pollacci (7) reported grape leaves treated with sulfur produced hydrogen sulfide gas. Recently it has been reported that hydrogen sulfide gas is produced by sulfur-dusted lemons and oranges (22). This gas which emanates from sulfured plants is also produced by the reactions of ingredients in the widely used lime-sulfur sprays. St. John and Groves (9) have excellently reviewed the chemistry of these mixtures.
