P7.38 A natural gas stream (100 kgmol/h) contains 98mol% methane (CH4) and 2mol% hydrogen sulfide (H2S)H2S is a highly toxic gas. The concentration of H2S in the natural gas stream must be reduced to 0.01molHH2S before the natural gas can be used as a fuel or chemical feedstock. A process engineer recommends absorption in a single equilibrium stage with water as the solvent. The absorber operates at 35atm and 10C. Determine the required flow rate of water to the absorber
