Chemistry

Consider a feed stream to a Claus process that consists of 10.0mole% H2S and 90.0% CO2. Onethird of the stream is sent to afurnace where the H2S is burned completely with a stoichiometricamount of air fed at 1 atm and 25Â°C. The combustion reaction is H2S3 2 O2! SO2 H2O The product gases from this reaction are then mixedwith the remaining two-thirds of the feed stream and sent to areactor in which the following reaction goes to completion: 2H2SSO2! 3S 2H2O The gases leave the reactor at 10:0 m3/min, 320Â°C, and205 kPa absolute. Assuming ideal-gas behavior, determine the feedrate of air in kmol/min. Provide a single balanced chemicalequation reflecting the overall process stoichiometry. How muchsulfur is produced in kg/min?
