30 points You are asked to remove 95% of H2S in a gas stream of air and H2S that flows at the rate of 250 m3/min and contains 8.0 mol% H2S. The H2S is to be removed by a stream of water using an absorption column. The entering water contains no H2S. You may assume that the air is completely insoluble in water and that the water is nonvolatile. The temperature is 313 K, and the pressure on the process is 3.5 atm. a Draw and label a flow diagram for the process. b Find the flow rate of water (in mol/min) needed to remove the H2S assuming that the exit water is in equilibrium with the entering gas. The Henry's Law constant for H2S in water at 313 K is 745 atm/mol fraction.
