In a certain equipment used for the absorption of SO₂(sulphur dioxide) from air by water, at one section,the gas and liquid phase concentrations of the solute are 10 mol% and 4 mass% respectively.The solution density is 61.8 lb/ft3. At the given temperature (40°C) and pressure (10 atm), the distribution of the SO₂ between air and water can be approximately described as pA = 25 (xA),where pA is the partial pressure of SO₂ in the gas phase in atm. The individual mass transfer coefficients are kx = 10 kmol/(h–m 2 –Δx) and ky = 8 kmol/(h–m 2 –Δy). Calculate the overall coefficient, KG in kmol/(h–m 2 –Δp in mm Hg) and xAi and pAi at the gas-liquid interface.
