Sulphur dioxide is to be scrubbed from an air stream in a small packed tower by contacting it with an organic amine. The feed gas is 3 % SO2 by volume, and 95 % of it is to be absorbed. The total gas rate is 150 m3 /h at 20 oC and 1.1 bar absolute pressure. The liquid enters the column at a rate of 1.40 kmol/h. Determine the overall gas phase mass transfer units and packed height if the column is 1 ft in diameter. Given: the overall mass transfer coefficient, KG = 3.2 x 10-4 kmol/(m2 )(s) (AP, bar); The effective gas-liquid contact area = 105 m2 per m3 of packed volume; 3 130/() (0) y ka kmol m hy Slope of the equilibrium line, m = 0.17 Sulphur dioxide is to be scrubbed from an air stream in a small packed tower by contacting it with an organic amine.
