A packed column absorbs SO2 from a gas containing 6% SO2 and 94% air by mol. used for. The inlet gas flow rate is 400 kg/h. SO2 concentration in the emitted gas should not exceed 0.4%. Water is used at a rate of 10 000 kg/h. The process is carried out at 1 atm pressure and 30°C. It In operating conditions, the equilibrium relation can be expressed as y=30.x. Accordingly, the necessary assumptions by doing; a) If the gas phase total transfer unit height is taken as 0.5 m, the total filling height, b) Calculate the column diameter for a pressure drop of 200 N/m2 across 1 meter of filling in the gas phase. Additional data: Density and viscosity values ​​of water at 30°C are 1000 kg/m3 and 8.5x10-4 kg/m.s, respectively.
