The raw feed to a sulfur removal system contains 15 mol% CO2, 7% H2S, and the balance is CH4. The fresh feed to the unit is 100 kmol/h. The original absorber design places a maximum flow rate limit of 80 kmol/h, and yields a product stream with only 1% H2S, and the balance is CO2 and CH4. The absorber removes H2S only. The excess feed flow rate is bypassed and blended with the product stream. Draw and label the process flowchart. Find the CO2 mole fraction in the absorber exit gas stream
