Hydrogen Sulfide has to be removed from a light refinery hydrocarbon stream before the gas is subject to further processing. The feed gas contains 4.0 mole% H₂S, and 98% of which has to be removed by absorption with a weak aqueous basic solution in a packed column. The feed gas rate is 80 kmol/h, and the entering solution has negligible amount of H₂S. The concentration of H₂S in the absorbent solution leaving the column is 0.015 mole H₂S per mole of the H₂S-free liquid. The equilibrium relation is linear and is given by y = 1.95 x. The 1.0 m diameter column operates at 25°C and 101.3 kPa total pressure. If the overall gas-phase film coefficient is Kya = 130 kmol/m³.h.Ay, calculate - (a) the molar flowrate of entering liquid solution, L (b) the number of transfer units, NOG (c) the packed height, CT
