Hydrogen sulfide 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 refining natural gas. in such instances, the claus process provides a means of converting 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 h 2 s + 3 2 o 2 → s o 2 + h 2 o 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: 2 h 2 s + s o 2 → 3 s + 2 h 2 o the gases leave the reactor at 10.0 m 3 / 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 reflecting the overall process stoichiometry. how much sulfur is produced in kg/min?
