Hydrogen sul?de has the distinctive unpleasant odor associated with rotten eggs, and it is poisonous. It often must be removed from crude natural gas and is therefore a product of re?ning natural gas. In such instances, the Claus process provides a means of convening H2S to elemental sulfur.
Consider a feed stream to a Claus process that consists of 10.0 mole% H2S and 90.0% CO2. One- third of the stream is sent to a furnace where the H2S is burned completely with a stoichiometric amount of air fed at 1 atm and 25°C. The combustion reaction is
The product gases from this reaction are then mixed with the remaining two-thirds of the feed stream and sent to a reactor in which the following reaction goes to completion:
The gases leave the reactor at 10.0 m3/min, 320°C, and 205 kPa absolute. Assuming ideal-gas behavior, determine the feed rate of air in kmol/min. Provide a single balanced chemical equation re?ecting the overall process stoichiometry. How much sulfur is produced in kg/min?
