Q2. A gas mixture containing 9.8 mole % CO2 and 2.4 mole % ethanol is passed through an absorption tower to separate ethanol using water as solvent. The gas mixture enters from the bottom of the tower at a rate of 7980 m/h, at 298 K and at a pressure of 1.11 atin. Water enters from top of the tower with a flow rate of 6490 kg/h and at 298 K. The expected recovery of ethanol will be 80 %, and the maximum permissible pressure drop for the gas stream should not exceed 250 N/m. The value of the Henry's law constant for the ethanol - water system corresponding to a temperature of 298 Kis H = 0.270 atm. Assume 69% flooding condition. Use the equilibrium relationship y* = m x. Select a 50 mm ceramic raschig rings as packing material, Evaluate the following with suitable assumptions. (0) Number of ideal stages (ii) Flow Parameter
