Absorption 5 A wetted-wall column is used for absorbing sulphur dioxide from air by means of a caustic soda solution. At an air flow of 2 kg/m²s, corresponding to a Reynolds number of 5160, the friction factor R/pu² is 0.0200. Calculate the mass transfer coefficient in kg SO₂/s m²(kN/m²) under these conditions if the tower is at atmospheric pressure. At the temperature of absorption the following values may be used: The diffusion coefficient for SO₂ = 0.116 x 10-4 m²/s, the viscosity of gas = 0.018 mNs/m², and the density of gas stream= 1.154 kg/m³.
