plz solve it and show me the diagram. also whichstream is the exit gas stream?..

Problem 4.5: (30 marks) 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 maximum flow rate entering the absorber is 80 kmol/h. Any excess in the raw feed is bypassed to the top product of the absorber. The top product stream yields with only 1% H2S, and the balance is CO2 and CH4. The absorber removes H2S only from the bottom. Draw and label the process flowchart. Find the CO2 mole fraction in the absorber exit gas stream
