Hydrogen sulfide is poisonous. it must be removed from crude oil. claus process allows for removing h2s from crude oil by converting it into elemental sulfur. a feed stream to the claus process consists of 10 mole % h2s and 90 mole % co2. one third of the stream is sent to a furnace where the h2s is burnt completely with stoichiometric amount of air fed at 1 atm and 25 oc. the combustion reaction is as follows: h2s+ 3 2 o2 so2+h2o. the produce gases from this reaction are them mixed with the remaining two-thirds of the feed stream and sent to a reactor in which the following reaction goes to completion: 2h2s+so23s+2h2o. the gases leave the reactor at 10.0 m3 /min, 320 oc, and 205 kpa absolute. assuming ideal gas behavior, determine the feed rate of air in kmol/min. how much sulfur is produced in kg/min?
