A certain plant requires SO2 solution in water which can be prepared by absorbing SO2 gas in pure water. The source of the SO2 is a sulfur burner which issues a gas consisting of 12 % SO2, 10% O2 and 78 % N2. 90 kg-mol/hr of this gas is available. The resulting solution is 1 % SO, by weight. The outgoing gas has a partial pressure of SO2 equal to 2.6 mm Hg and a partial pressure of water equal to 20 mm Hg. The total pressure is 760 mm Hg at 35C. Find the liquid water requirements in kg/h, the volumetric flow rate of the exit gas and the % recovery of the SO2 gas.
